Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a novel tea manufacturing and roughing method and a tea manufacturing and roughing device. Specifically, the tea manufacturing conditions involved in the rough rolling process, that is, the transition of control values of tea manufacturing elements such as hot air temperature, hot air volume, spindle rotation speed, and spindle position, are determined by fresh leaf quality, steaming conditions, etc. In addition to creating ready-made patterns according to steamed leaf quality, etc., the rough kneading time can also be set arbitrarily by the user.
Even if the same existing pattern is selected, if the rough rubbing time set above is different, the control values of each step of the existing pattern can be made to change at different times. Therefore, even if the number of ready-made patterns is limited, it is easy to set more optimal roughening conditions according to the infinitely changing quality of steamed leaves, even for those with little experience in managing the roughening process. It can be kneaded in a relatively short period of time without causing any rejection reactions, and in cases where there is a skilled engineer for rough rolling process control, or where there is a certain amount of experience and ready-made patterns are not enough, When you want to perform detailed and original operations, you can continue to change the control values of each tea manufacturing element in the same pattern as the previous operation that produced a good product. Experienced technicians can leave the scene with peace of mind, and inexperienced technicians can further hone their skills by observing the process being reproduced.On the other hand, in terms of quality, It is an object of the present invention to provide a new tea manufacturing method and a tea manufacturing and rough rolling apparatus which make it possible to always obtain coarsely rolled leaves of a certain quality or higher regardless of the degree of roughening.

Background technology and its problems The significance of the tea manufacturing process is that the tea leaves steamed in the previous process are gradually dried with hot air while stirring and rolling pressure in a rolling drying chamber until the residual water content in the tea leaves reaches approximately 50%. .

The tea manufacturing and rough rolling process is generally performed as follows. That is, a main shaft is rotatably arranged in a drying chamber having a roughly semi-cylindrical kneading barrel, and a kneading hand for pressing the tea leaves against the inner surface of the kneading barrel and applying pressure to the main shaft, and a kneading hand for scooping up the tea leaves. A dredge for stirring is attached, and the tea leaves that have undergone the steaming process are put into the drying chamber, and the main shaft is rotated to apply pressure and agitation to the tea leaves. Hot air is supplied into the drying chamber to gradually dry the tea leaves.

By the way, in the tea manufacturing process, it is important to maintain the leaf temperature at around 36 to 37 degrees Celsius while drying the leaves as constant as possible without over-drying. If these requirements are not met, the tea leaves will yellow, break, and
This results in various quality deteriorations such as a grassy smell or a stuffy smell.

Therefore, in general, in order to carry out the rough rolling process, the tea manufacturing conditions involved in the rough rolling process, such as the temperature and amount of hot air supplied into the rolling drying chamber, the rotation speed of the main shaft, the position of the leaf stopper, or the rolling barrel of the main shaft, must be adjusted. Each tea manufacturing element, such as its position relative to the inner surface, is appropriately controlled.

However, such control is extremely difficult, and it is impossible to unconditionally define the control value. This is because tea is, so to speak, a living thing, and for example, there are differences in the time of picking, such as visible and stiff buds, differences in tea varieties, differences in production areas, differences in annual rainfall and sunshine hours, and differences in the day before the day of harvesting. The condition of fresh leaves changes slightly due to various conditions such as differences in weather, and furthermore, the quality of the steamed leaves introduced into this rough rolling process varies depending on the steaming treatment in the previous process. This is because it is something you do.

In addition, the properties of the tea leaves in the rough rolling process gradually change as the process progresses.
For example, the shape gradually withers, the water content gradually decreases, the exudation of internal water gradually becomes slower, and the leaf clusters gradually form clumps.

Therefore, it is necessary to control each of the above-mentioned tea manufacturing factors according to the above-mentioned differences in the quality of the steamed leaves and the progress of the process. However, even when controlling according to differences in steamed leaf quality or the progress of the process, it is difficult for inexperienced process managers to judge the difference in steamed leaf quality or the progress of the process. Needless to say, it has become extremely difficult to control tea manufacturing elements using specific control values.

Moreover, the requirements necessary for controlling each of the above-mentioned tea manufacturing elements are not only the "control value" but also the time for sustaining the control value, that is, the "step time". This is because, as mentioned above, the properties of the tea leaves in the rough rolling process change gradually as the process progresses, so even if the control value is the same, if the duration of the control value is different, the tea manufacturing conditions for the tea leaves will be different. This is because, especially in the rough-milling process, subtle differences in the duration of this control value greatly affect the quality of the coarsely-milled leaves.

From this point of view, in the tea manufacturing and rough rolling process, a skilled technician called a tea master is always by the side of the rough rolling machine and monitors the progress of the rough rolling process. The reality is that each tea manufacturing element, such as the temperature of hot air, is controlled during the coarse rolling process, based on experience and intuition, with reference to texture, wetness, etc. In addition, tea manufacturing is carried out in a battlefield-like environment, and it is difficult to record the opening of the airflow damper and the duration of the opening, which are changed at any time during the roughening process. do not have.

Under these circumstances, in this industry, even inexperienced process managers have been able to obtain rough-milled leaves of a certain quality or higher, and what is more, even they can easily operate the rough-milling process. There has been a strong demand for the development of a tea processing and roughening method and a tea processing and roughening device that can be carried out easily and that can improve the skills of those involved.

Purpose of the Invention Therefore, the present invention has been made in view of the above-mentioned problems.The present invention has been made in view of the above-mentioned problems. By making it easier to set more optimal rough kneading conditions according to the steamed leaf quality, which is limited but infinitely variable, even inexperienced people can easily knead without causing rejection reactions, and it is also easier for experienced technicians to knead than they did last time. By making it possible to change the control values of each tea-making element even in the exact same pattern as the previous one, experienced technicians can leave the area with peace of mind, while inexperienced technicians can observe the process being reproduced. Once you have honed your technique and gained some experience, you can create your own patterns rather than using ready-made patterns and reproduce them to further hone your technique.On the other hand, in terms of quality, the rough rolling process To provide a new tea manufacturing method and a tea manufacturing and roughing device which can always obtain coarsely crushed leaves of a certain quality or higher regardless of the skill level of a manager.

Summary of the Invention Therefore, the tea manufacturing and rough rolling method of the first invention is characterized in that the temperature and volume of hot air sent into the rolling and drying chamber, the rotation speed of the main shaft on which the rolling hands and dredges are attached, the position of the main shaft, etc. In a tea manufacturing and rough rolling method in which one rough rolling process is completed while each tea manufacturing element is sequentially changed as the process progresses, one rough rolling process is performed for one or more tea manufacturing elements divided into a plurality of steps. In addition to preparing in advance multiple ready-made patterns that serve as indicators of the transition in the process, the process of the transition of the tea manufacturing elements that the user changes as desired during any coarse rolling process can be stored in memory as a user-created pattern. The rough kneading process is memorized so that one of the ready-made patterns and user-created patterns can be selected as needed in the rough-kneading process that is repeated thereafter, and when the ready-made pattern is selected, the rough-kneader time can also be arbitrarily set. The time allocated to each step of the selected ready-made pattern is calculated by dividing the rough kneading time set above by the total number of steps, and both the selected ready-made pattern and the set time are used as indicators. The present invention is characterized in that when a user-created pattern is selected, the selected user-created pattern is used as an index, one or more of the tea manufacturing elements described above are changed, and the rough rolling process of 1 is completed. The second invention tea rough rolling method uses a plurality of rolling and drying chambers, and the temperature and volume of hot air sent into the rolling and drying chambers, the rotation speed of the main shaft on which the rolling hands and dredges are attached, the position of the main shaft, etc. In a tea manufacturing and rough rolling method in which one rough rolling process is completed while each tea manufacturing element in the tea manufacturing and rough rolling process is sequentially transferred in each rolling and drying room as the process progresses, one or more tea manufacturing elements are In addition to preparing in advance a plurality of ready-made patterns that serve as indicators of the transition in one rough-rolling process divided into steps, the user can also use the The process of the transition of the tea manufacturing elements that has been changed as desired is stored in the memory as a user-created pattern, and one of the pre-made patterns and the user-created pattern is selected as a master pattern as necessary in the rough rolling process that is repeated thereafter. When a pre-made pattern is selected, the rough kneading time can also be set arbitrarily, and the time allocated to each step of the selected pre-made pattern is equal to the rough kneading time set above for all steps. It is calculated by dividing by a number, and both the selected existing pattern and the setting time are used as indicators, and when a user-created pattern is selected, the selected user-created pattern is used as an indicator, and one or more of the above It is characterized in that one rough rolling process in each rolling and drying room is completed by changing the tea manufacturing elements. In addition, the tea roughening device of the present invention has the following features:

EXAMPLES The details of the tea manufacturing method and tea manufacturing and roughing device of the present invention will be explained below. For convenience, the order of explanation will be first about the tea manufacturing and rough rolling apparatus, and then about the tea manufacturing and rough rolling method.

is provided, and a hot air blowing port 12 is opened at the rear surface. Reference numeral 13 denotes a tea leaf pool located at the upper end exhaust port of the stirring chamber 10. Tea leaves are put into this pool until a predetermined weight is reached, and the lower doors 14 are opened as shown by the two-dot chain line in Fig. 2. When you open it, pool 13
The tea leaves inside are put into a rolling drying chamber composed of a rolling barrel 4 and a stirring chamber 10. Furthermore, this tea leaf pool 13
is usually equipped with a tea leaf weight measuring device. 15 is a wire mesh that covers the upper end exhaust port of the stirring chamber 10. 16, 16... are displacement adjustment dampers arranged inside the wire mesh 15 at the upper end of the agitation chamber 10;
Damper adjustment motor 17 fixed to frame 3
The opening/closing degree is adjusted by. Reference numeral 18 denotes a hot air guide formed on the rear side of the stirring chamber 10, and one end thereof communicates with the hot air outlet 19 of the hot air generator 2.

The hot air generator 2 includes a heat exchange section 20 and an air supply fan 21
It consists of The heat exchange unit 20 includes a furnace cylinder 23 and hot air passages 24, 2 connected to the furnace cylinder 23 in a casing 22.
A burner 25 is attached to the furnace cylinder 23, and the burner 25 causes the furnace cylinder 2 to
The hot air generated within the casing 22 is discharged from the chimney 26 through the hot air passages 24 arranged in a maze-like manner within the casing 22. Incidentally, the burner 25 is provided with, for example, two nozzles that generate different amounts of heat (not shown), and these two nozzles can be used to ignite two nozzles, ignite one, ignite the other, and so on. By operating in different modes, the amount of heat can be adjusted in three stages.

Air is introduced from the outside directly or through a suitable filter by an air fan 21, enters the casing 22 through an air inlet 27 communicating between the air fan 21 and the casing 22, and enters the casing 22 through a hot air outlet. 19 into the hot air conduit 18. Then, when the air passes through the casing 22,
It comes into contact with the heated surfaces of the furnace cylinder 23 and the hot air passages 24, 24, and is heated to become hot air. Then, this hot air is supplied into the drying chamber from the hot air blowing ports 12, 12, . . . through the hot air guide 18. Although not shown, a damper for adjusting the amount of hot air whose opening/closing degree is controlled by a control motor 28 is arranged between the air supply fan 21 and the air supply port 27 .

The rough kneading process using the above-described rough kneader 1 is performed as follows. A predetermined amount of tea leaves that have completed the steaming process are introduced into the pool 13,
When the doors 14, 14 of the steamed leaf pool 13 are opened, the leaves are thrown into a drying room consisting of a kneading barrel 4 and a stirring room 10. The hot air generated by the hot air generator 2 passes through the hot air guide 18 to the hot air inlet 12,
12... is supplied into the drying chamber. Then, the main shaft 7 is rotated, and the tea leaves are pressed and kneaded against the kneading bottom by the kneading hands 8, 8, . and,
The tea leaves come into contact with hot air while being rolled and agitated.
It is gradually dried and then subjected to a rough rolling process. The above operation is continued until the residual water content of the tea leaves reaches a predetermined value, and when the desired value is reached, the roughening process is completed, the take-out door 6 is opened, and the tea leaves are taken out onto the transportation conveyor 29 below. , and sent to the next rolling process.

As mentioned earlier, the tea manufacturing and rough rolling process described above is performed until the residual water content of the tea leaves steamed in the previous process is approximately
It is important to dry the tea leaves until the residual moisture content reaches 50%, but it is not enough to simply reduce the residual moisture content to about 50%; it must be done in a way that does not affect the quality of the tea leaves, such as their color and aroma. Must be. In order to do this, each tea manufacturing element in the tea manufacturing process, such as the temperature of the hot air supplied to the rolling drying chamber, the amount of hot air, the rotation speed of the main shaft, and the position of the main shaft, must be adjusted in accordance with the progress of the process. Therefore, it is necessary to proceed sequentially. Therefore, the means by which these tea manufacturing elements are controlled in the tea manufacturing and roughening machine 1 will be explained by giving an example of these means.

First, the temperature of the hot air supplied to the drying chamber is controlled by adjusting the combustion degree of the burner 25. In this case, a temperature sensor is placed at an appropriate location on the hot air guide 18, and this detects the temperature of the hot air blown into the drying chamber. In other words, one of three modes may be selected: both of the two nozzles are ignited, only one is ignited, and only the other is ignited.

The amount of hot air supplied into the drying chamber depends on the number of revolutions of the air supply fan 21, the opening/closing degree of the exhaust volume adjustment dampers 16, 16, etc. in the upper part of the drying chamber, and the air supply ports of the air supply fan 21 and the heat exchange section 20. It can be controlled by adjusting one or more of the opening/closing degrees of the damper disposed between the damper 27 and the damper 27.

The rotation speed of the main shaft 7 can be controlled, for example, by a mechanism shown in FIG. 30 is the main shaft drive unit 5
On this frame 30 is a reducer 3.
1 is fixed, and the output shaft (not shown) of this reducer 31 is connected to the main shaft 7 directly or via a universal joint or the like.
32 is a reducer pulley, which is connected to the input shaft 33 of the reducer 31.
is fixed. 34 is part 3 on frame 30
A main shaft drive motor 36 is fixed onto the speed change base 34, which is rotatably supported by the speed change base 5. A variable diameter pulley 38 is attached to the output shaft 37 of the main shaft drive motor 36, and a V belt 3 is connected between the variable diameter pulley 38 and the reduction gear pulley 32.
9 have been constructed. This variable diameter pulley 38 is formed by two members whose grooves for suspending the belt are joined by elastic pressure means, and when the speed change base 34 rotates in the direction of the solid line arrow, the pulley 38 moves away from the other pulley 32. As it moves away, the elastic force of the V-belt 39 acts between the two members forming the groove and widens the gap between them. As a result, the diameter of the groove in which the belt is placed has become smaller. Further, when the speed change base 34 rotates in the direction of the dotted arrow, the two members forming the groove move closer to each other by the elastic pressure means, and as a result, the diameter of the groove becomes larger. Reference numeral 40 denotes a speed change rod rotatably supported by the frame 30 at an intermediate portion 41. A sliding pin 42 is slidably engaged at one swinging end of the speed change rod 40 in an elongated sliding hole 43 provided at the free end of the speed change base 34.
The free end of the transmission base 34 is constantly pulled in the direction of the arrow by a spring 44. A long sliding hole 4 is provided at the other swinging end of the speed change rod 40.
5 is formed. Reference numeral 46 denotes a control motor fixed on the frame 30, which includes a rotation transmission system 47 and a reduction gear 4.
8 to swing the control rod 49. A roller 50 is rotatably provided at the swinging end of the control rod 49.
is slidably engaged with a sliding hole 45 of the speed change rod 40.

Therefore, the control rod 4 is controlled by the control motor 46.
9 is swung, the speed change rod 40 is also swung, and as a result, the speed change base 34 is swung, and the groove diameter of the variable diameter pulley 38 is increased in accordance with that direction.
Alternatively, the rotation speed applied to the input shaft 33 of the reduction gear 31 is changed via the pulley 32 by reducing the rotation speed of the main shaft 7, thereby changing the rotation speed of the main shaft 7.

Adjustment of the relative position of the main shaft 7 with respect to the kneading bottom can be accomplished, for example, by using a mechanism as shown in FIGS. 4 to 6. 51 is massaging body 4
This is a disk-shaped bearing disk that is rotatably supported by the frame 3 at both end positions of the frame 3. A bearing portion 52 for receiving an end of the main shaft 7 is formed at a position eccentric from the center of rotation of the bearing disk 51, and the end of the main shaft 7 is supported by the bearing portion 52. Reference numeral 53 designates a changing rod whose one end is fixed to the bearing disc 51, and the other end of which is formed with a long hole 54 extending in the longitudinal direction.
A control motor 55 is fixed to the frame 3, and a control rod 57 is fixed to its output shaft 56. A pin 58 is provided at the tip of the control rod 57, and this pin 58 connects to the aforementioned change rod 53.
It is slidably engaged with the elongated hole 54 of. It should be noted that the bearing disc 51, change rod 53 and control rod 57 as described above are provided not only on one side but also on the other side.

When the control rod 57 is rotated by the control motor 55 around the position of the output shaft 56 of the motor 55, the change rod 53, which is engaged with the tip thereof, rotates around the center of the bearing disk 51. Rotate as. Accordingly, the bearing plate 51 which is in a fixed relationship with the changing rod 53 is also rotated, and the position of the bearing portion 52 is changed as shown by the two-dot chain line. Therefore, the position of the main shaft 7 supported by the bearing portion 52 is changed. By changing the main shaft in this manner, the degree of pressure of kneading the tea leaves is changed. For example, if the main shaft 7 is at the position shown by the solid line in FIG.
will draw a trajectory shown by dotted line A, but when the position of the main shaft 7 reaches the position shown by the two-dot chain line in FIG. The degree of kneading pressure applied to the tea leaves by the kneading hands 8 that are being rotated is increased compared to the case where the locus A is drawn. Therefore, by appropriately changing the position of the main shaft 7, the optimum degree of kneading pressure can be selected.

Reference numeral 59 denotes a leaf stopper plate disposed approximately in the upper center of the stirring chamber 10 so as to traverse it in the longitudinal direction. The leaf stopper plate 59 has links 60 ₁ , 60 ₂ , 6
It is connected to a control motor 61 via a _0.03 mechanism, and is configured to rotate about a shaft 62 as shown by the two-dot chain line in FIG. The locus of the tea leaves scraped up by the dredges 9, 9, . . . changes depending on the position of the leaf stopper plate 59. That is,
The locus will be drawn as shown by the arrows I to D corresponding to the symbols I to D added to the reference numeral 59 of the leaf stopper plate in FIG. Then, as the trajectory changes from A to D, the tea leaves fall directly below the main shaft 7, and the degree of kneading of the tea leaves increases.

Next, the details of the present invention will be explained in detail below.
As shown in FIG. 8, for a tea processing and roughing device consisting of four machines 1a to 1d arranged, a so-called microprocessor is used to control the temperature, hot air volume, and main shaft 7 of the hot air supplied to the rolling and drying room. An example will be explained in which the method is implemented for the purpose of automatically controlling only the rotation speed and the spindle position. In addition, in Fig. 8, 63 is a steamed leaf processing machine, 64 is a vertical bucket, 65 is an inclined conveyor,
66 is a horizontal conveyor, 67, 67 are input conveyors, and the tea leaves that have been steamed pass through a processing machine 63, and are transferred to a vertical bucket 64, and each conveyor 65, 66, 67,

Stamp indicating the position of the knob, 77
Reference numerals a to 77d are display lamps, which indicate the number of the master roughing machine 1, and the one indicating the number of the roughing machine 1 whose process is most advanced among the four roughing machines 1 is lit. "Program protection"
is a mark indicating the position to prevent the pattern from being rewritten or erased, and is intended to prevent the carefully created pattern from being rewritten if touched by another worker. Reference numeral 78 is a load/store switch, and when it is turned to the calling side, it transfers the pattern in the store area with the number (recording number) specified with the store area designation knob 75 to the working area for the coarse kneading machine 1 with the number designated with the pattern selection switch 76. When transferred, or when turned to the recording side, the pattern in the working area corresponding to the roughing machine 1 with the number specified by the pattern selection switch 76 is stored in the store area with the number specified by the store area designation knob 75.

Reference numeral 79 is a rough kneading time setting device, and the user can arbitrarily set the time for the rough kneading step 1, that is, the time from when the steamed leaves are put into the kneading drum 4 to when they are taken out from the kneading drum 4. In this embodiment, the rough kneading time is set in minutes. The rough kneading time is set by operating the push button type setting switches 80, 80. The rough kneading time set by the rough kneading time setter 79 also becomes important data for calculating the time allocated to each step of the existing pattern selected by the pattern selection switch 76. That is, in the present invention, when a ready-made pattern is selected, the time allocated to each step of the selected ready-made pattern is the rough kneading time set by the user divided by the total number of steps of the selected ready-made pattern. It is determined by the calculation. For example, if the existing pattern is made up of 40 steps and the set rough kneading time is 40 minutes, the time for each step is 40 (minutes) ÷ 40 (steps) = 1 (minutes). Also, even if the same ready-made pattern as above is selected, if the set rough kneading time is "32 minutes", the time for each step will be 32 minutes.
(minutes) ÷ 40 (steps) = 0.8 (minutes). Therefore,
Even with one ready-made pattern, the time of each step may vary depending on the rough kneading time set.

Embodiment of the Method Next, the tea manufacturing and roughening method of the present invention will be described using the above-described tea manufacturing and roughening apparatus and according to an example of an embodiment carried out according to the flowchart shown in FIG.

(1) For example, the properties of tea are well-defined, and there are eight established patterns, i.e., patterns predetermined based on past experiments and results (for example, hot air temperature, hot air temperature, etc. as shown in Figure 12). rough rolling can be performed using any of the following:

(a) Place the pattern selection switch 76 in one of the eight ready-made patterns. For example, if the steamed leaves that you are about to undergo the rough rolling process are ordinary fresh leaves that have been deeply steamed,
Place it in the position labeled "Normal leaf/deep steaming".

(b) Push button 8 of rough kneading time setting device 79
Set an arbitrary rough kneading time by 0.80.

(c) A rolling drying room to be operated, for example, the first rough rolling machine 1a
Press the input command switch 82a for the drying room,
The steamed leaves to be roughly rubbed are put into the rubbing and drying chamber.
When using the automatic loading device, if the loading device is activated by the loading command button 82, the operator does not need to do anything.

(d) In this case, as shown in Fig. 11, after the program starts or after the previous roughing process is completed, the hot air temperature, hot air volume, spindle rotation speed, and spindle position are set to the initial values, that is, as shown in Fig. 12. Initialization is performed to set the value to the value at the start of . Then, when the input command switch 82a is pressed and rough kneading is started, since the operation is based on an existing pattern, the question ``What is the pattern selection?'' is ``existing'', and therefore the specified existing pattern is transferred from the memory ROM to the memory. It is transferred to the working area corresponding to the rough kneading machine 1a in the RAM. At the same time, the time allocated to each step of the existing pattern is determined by dividing the set rough kneading time by the total number of steps of the existing pattern, as described above.
Therefore, for example, if the specified ready-made pattern is a pattern divided into 40 steps as shown in FIG.
If the setting is set to "minute", the roughing machine 1a will be controlled according to the control value of each step and its time as shown in FIG.

(e) Furthermore, each sensor 95 of the roughing machine 1a
The values of the hot air temperature, hot air volume, main shaft 7 rotation speed, and main shaft 7 position of the roughing machine 1a detected by a, 96a, 97a, and 98a are read, and are instructed by the pattern written in the working area. It is compared with the value at that time, and if there is a difference, the hot air temperature controller 92a and each control motor 17a,
Correction signals are sent to 46a and 55a.
Note that when the program is executed immediately after starting, each tea making element described above is set to the initial value by the initialization described above, and there is no need to read the value of each tea making element, but when the program is repeated again. From now on, this step is necessary.

Such a program can be run using the coarse kneading time setting device 7.
Until the rough kneading time set in step 9 has passed, the process is repeated because "Is the rough kneading time over?" is "NO", and the values of each control element such as hot air temperature are changed every step time calculated above. For example, in the above-mentioned example, the value is successively changed to the value determined by the existing pattern, for example, the value shown in FIG. 12, every minute passes.

(f) Then, when the above-set time, that is, 40 minutes have elapsed since the input, the "Rough kneading time is over?" becomes "YES", and the ejector is removed to the automatic ejector (not shown) by opening the ejecting door 6, etc. When the operation command is given, the buzzer 73 sounds to notify the end of the rough rubbing process.

Even though the start time of such operation is different for each roughing machine, the value of each control element is individually changed from the beginning of the established pattern.

As a result of specifying a pre-made pattern as described above, setting a certain rough rolling time, and executing the rough rolling process, if a good coarsely rolled leaf or rough tea product tea can be obtained, If the steamed leaves to be input into the next coarse rolling process are of the same type, specify the same ready-made pattern as the previous one,
Moreover, it is sufficient to set the same rough kneading time as the previous time.
On the other hand, if the rough rolling process results in rough rolled leaves or rough tea product tea that is not very good,
This time, for example, even if the same ready-made pattern as the previous one is specified, the rough kneading time to be set is different from the previous one. That is, as described above, even if the same ready-made pattern is specified, the coarse kneading time to be set is different from the previous time. That is, as described above, even if the same existing pattern is specified, if the set rough kneading times are different, the time of each step of the existing pattern will be expanded or contracted, and as a result, different controls will be performed.

However, the ready-made patterns prepared in advance are
For example, a control value for rough rolling conditions that is optimal for a specific steamed leaf quality (in this example, steamed leaf quality classified by a combination of fresh leaf quality and degree of steaming) is given. Therefore, add the usual rough rolling time to this, for example, 40 minutes for Ichibancha.
By setting the rough rolling time to around 35 minutes for summer tea, even an inexperienced rough rolling process manager can produce rough rolled leaves of a quality that is better than the standard quality. be able to. Furthermore, if the rough kneading time is changed and set as appropriate, even better quality coarsely kneaded leaves can be obtained.

(2) The user can set the value setting switches 83a to 83d, 8 for each tea making element without using a ready-made pattern.
4a-84d, 85a-85d and 86a-8
6d to create individual patterns for each roughing machine 1a to 1d.

(a) “Individual creation” of pattern selection switch 76
position.

(b) Roughing machine to be operated, for example, first roughing machine 1a
Press the input command switch 82a and input the tea leaves to be coarsely crushed. As shown in the flowchart in Figure 11, "What is the pattern selection?" is "Individual", so "Individual pattern is used for each rolling and drying room", and each tea manufacturing element of each roughing machine has a memory RAM. The circuit is configured so that the individual patterns stored in the working area corresponding to each roughing machine in the machine are used as indicators. In addition, when the user creates a pattern, in this embodiment, 1 address is prepared for each minute of rough rolling time, a total of 64 addresses, and the progress of the transition of each tea manufacturing element during the rough rolling process of up to 64 minutes can be memorized. That's what I do.

Then, suppose that the first part of the working area corresponding to the first roughing machine 1a of the memory RAM is
At each address corresponding to the minute, there is a message that says ``Hot air temperature is 95℃,
If a word is written indicating that the hot air volume is 150 m ³ /min, the spindle rotation speed is 42 rpm, and the spindle position is at position 1, then the values of each of these tea manufacturing elements will be kept at that value for 1 minute after input. . In the case of this embodiment, the working area for pattern storage in the memory RAM is not initialized at the start of the roughing process, so the working area corresponding to each of the actual roughing machines 1a to 1d is The progress of changes in each tea manufacturing element, such as the hot air temperature in the rough rolling process performed previously, is memorized, and unless the switches are operated, these tea manufacturing elements will change according to such a pattern.

(c) Then, for example, after one minute has passed, the main shaft rotation speed setting switch 85 corresponding to the roughing machine 1a is turned on.
When operating a and increasing the spindle rotation speed from 42 rpm to 43 rpm.

In the flowchart of FIG. 11, the switch 8
An interrupt is generated by the operation in step 5a, and the question ``What is the pattern selection?'' becomes ``individual creation of a drying room'', and the word corresponding to the changed rotation speed of 43 rpm is assigned to the address corresponding to the elapsed time in the working area (e.g. It is stored at the corresponding address from 1 minute to 2 minutes after the start.

In this embodiment, each setting switch 83a~
When 83d, 84a to 84d, 85a to 85d, and 86a to 86d are pressed and the value of the corresponding tea manufacturing element changes, for example, as described above,
When the rotation speed of the spindle 7 is changed after one minute has elapsed, the word corresponding to the rotation speed of 43 rpm is written from the address corresponding to that point in the working area of the memory RAM to the address of the last 64 minutes. If these setting switches 85a to 85d are not operated thereafter, the rotational speed of the main shaft is maintained at the rotational speed written in the memory, that is, 43 rpm, as shown in the flowchart of FIG.

(d) When the value of each tea manufacturing element is changed as the rough rolling process progresses, the addresses after the address corresponding to the time of the change are rewritten each time.

(e) When the desired pressure and shaping are applied, the user presses the eject button (not shown).
When the tea leaves are taken out by opening the take-out door 6, the take-out limit switch 90a linked to the take-out door 6 is closed. As a result, the time required from the start to the end of rough kneading, that is, the time for one rough kneading process, is stored in a predetermined address of the memory RAM, and in FIG. 11, "Is the rough kneading time over?"'', and the hot air temperature, hot air volume, main shaft rotation speed, and main shaft position of the roughing machine 1a are returned to their initial values.

Through the above operations, the working area of the memory RAM corresponding to the rolling/drying room stores the transition of each tea manufacturing element such as the hot air temperature operated by the user during the first rough rolling process for that rolling/drying room as a user-created pattern.

Therefore, if good coarsely rolled leaves or rough tea product tea can be obtained as a result of the current operation,
From the next rough rolling process, each tea manufacturing element such as the hot air temperature may be changed using the user-created pattern as necessary.

On the other hand, if only coarsely rolled leaves or crude tea product tea that is not very good is obtained, the above-mentioned operation is repeated, a new user-created pattern is created, and as many trials as there are available.

If an inexperienced person is operating the operation and there is not enough time, ask a skilled technician to take a look at it once, and then use the user-created patterns created by the skilled technician to transition each tea manufacturing element, and then check the process. You can learn a lot by checking the changes in the properties of the tea leaves inside, and then trying to transform the user-created patterns created by skilled technicians in your own way.

In addition, the pattern selection switch can be created individually.
When placed in the position of
are stored as separate patterns for each working area.

(3) When performing rough rolling work using any of the rolling and drying rooms, for example, the No. 1 rolling and drying room as the master.

(a) Set the pattern selection switch 76 to "1st coarse"
Make it.

(b) Press the input command button 82a and input the tea leaves to be coarsely crushed into the rolling/drying chamber.

(c) As a result, in Figure 11, ``What is the pattern selection?'' becomes ``master op'', and the circuit is configured so that only the working area corresponding to the designated drying room is used, and all Changes in each tea manufacturing element such as hot air temperature in the rolling and drying room are performed using the pattern of the master rolling and drying room as an index. Of course, in the case of operation using the master pattern, the transition of each tea manufacturing element is performed individually from the beginning of the master pattern, as described above, even if the starting time is different for each rolling drying room.

Therefore, if you master the pattern of a rolling drying room that has already been tried and obtained good results, each tea making element in the other rolling drying rooms will perform exactly the same movements as the rolling drying room that has yielded good results. I will do it.

(d) In addition, this kind of operation using a master pattern can be carried out as a master pattern in the rolling and drying room where an expert is currently working alongside and adjusting each tea manufacturing element such as the hot air temperature while proceeding with the rough rolling process. This can also be done by changing the tea manufacturing elements in other rolling and drying rooms.

That is, for example, when the drying chamber of the first roughing machine 1a is used as the master, the main shaft rotation speed setting switch 8 is set for the drying chamber of the first roughing machine 1a.
5a is operated, the rotation speed of the main shaft of the drying chamber of the first roughing machine changes accordingly, and as shown in FIG.
An interrupt operation is performed by the operation, and "What is the pattern selection?" is the "master op".Therefore, using the same procedure as in the case of individual creation, it is placed in the kneading drying room of the first rough kneading machine 1a, which is the master. A word corresponding to the changed spindle rotation speed is written to all unexecuted portions of the corresponding working area after the address corresponding to the time of the operation.

(f) Thereafter, whenever the number of revolutions changes, a word corresponding to the new number of revolutions is written in the working area corresponding to the kneading and drying chamber of the first roughing machine 1a at the address after the address corresponding to that point in time. .

(g) When the rough rolling process is completed, if you take out the tea leaves in the same way as when making individual tea leaves, the elapsed time from the start will be stored in a predetermined area of the memory RAM, and the initialization, That is, an operation is performed in which the value of each tea manufacturing element is returned to its initial value.

(h) In this case, if the rolling and drying rooms other than the master rolling and drying room are ready to be loaded with tea leaves, press the input command switches 82b to 82d sequentially to start rough rolling. 1 minute after the main shaft rotation speed in the drying room starts
43rpm, and if it becomes 45rpm after 2 minutes, then the main shaft rotation speed of the kneading and drying chamber of the second rough kneading machine 1b will also change to 43rpm 2 minutes after 1 minute has passed after rough kneading started in the kneading and drying room. at the point when it has passed
44 rpm, etc., using the master user-created pattern for the drying room as an indicator.

(4) When rough rolling was initially started using the existing pattern as an indicator, but the progress was not as desired.

(a) In this case, set the pattern selection switch to ``Individual Creation'' or ``Master 1st Rough
4. Roughly knead.

(b) As a result, after the switching point, each setting switch 83a to 83d, 84a to 84d, 85
By operating the setting switches a to 85d, 86a to 86d, or the master rolling and drying chamber, the values of the tea manufacturing elements can be adjusted. In this case, the existing pattern transferred from the memory ROM remains as it is at the address before the address corresponding to the switching point of the working area corresponding to the drying room, and the address after that address remains as it is. The transition of tea manufacturing elements operated by the user is recorded, and this can also be used as a new user-created pattern.

The operations for each pattern have been explained above, but in the case of this embodiment, the memory RAM is backed up by a battery, and data is saved even if the power switch 72 is turned off.

Therefore, for example, if the results of the transition of each tea manufacturing element in the rolling/drying chamber of the second roughing machine 1b are good and the pattern is one that you would like to continue using in the future, for example, set the pattern selection switch 76 to the second roughing machine of the master, and select the store. Set the area designation knob 75 to position 1 and turn the load store switch 78 to the "record" side. By this operation, the pattern in the working area for the kneading and drying chamber of the second rough kneading machine 1b is transferred to the store area No. 1 of the memory RAM, and the buzzer 73 sounds when the transfer is completed. Other drying room patterns can be saved in the same way.

Then, using the pattern stored in such a store area as an index, for example, the first roughing machine 1a
When attempting to change the temperature of each tea manufacturing element such as the temperature of hot air in the rolling drying room, set the store area designation knob 75 to the number of the store area where the pattern to be used as the index is stored, and Set the pattern selection switch 76 to the drying chamber in which you want to change the pattern, and turn the load store switch 78 to the "call" side. As a result, the pattern in the store area is transferred to the working area of the selected drying room, and when the pattern is finished, the buzzer 73 will sound.
sounds. Then, when the rough rolling process in the rolling/drying room is started, each tea manufacturing element in the rolling/drying room changes with reference to the pattern.

Effects of the Invention As is clear from the above description, the tea roughening method of the first invention has the following advantages: , in a tea processing method in which one rough rolling step is completed while each tea manufacturing element in the tea manufacturing and rough rolling process is sequentially changed as the process progresses, such as the position of the main shaft, one or more tea manufacturing elements are In addition to preparing in advance a plurality of ready-made patterns that serve as indicators of the transition in one rough rolling process divided into steps, the user can change the tea manufacturing elements as desired during any rough rolling process. The progress of the transition is stored in the memory as a user-created pattern, and one of the existing patterns and the user-created pattern can be selected as necessary in the subsequent rough rubbing process, and when the existing pattern is selected, The rough kneading time can also be set arbitrarily, and the time allocated to each step of the selected ready-made pattern is calculated by dividing the set rough kneading time by the total number of steps. Both the ready-made pattern and the set time are used as indicators, and when a user-created pattern is selected, the selected user-created pattern is used as an indicator, one or more of the tea manufacturing elements described above are changed, and the rough rolling process of 1 is completed. The tea roughening method of the second invention uses a plurality of rolling and drying chambers, and the temperature and amount of hot air sent into the rolling and drying chambers are controlled by the temperature of the hot air sent into the rolling and drying chambers, and the rolling hands and dredges attached to the rolling and drying chambers. In a tea manufacturing and rough rolling method in which one rough rolling process is completed while each tea manufacturing element in the tea manufacturing and rough rolling process, such as the rotation speed of the main shaft and the position of the main shaft, is changed sequentially in each rolling and drying room as the process progresses. For one or more tea manufacturing elements, prepare in advance multiple ready-made patterns that serve as indicators of the transition in one rough rolling process divided into multiple steps, and For any coarse rolling process, the progress of the tea manufacturing elements changed as desired by the user during that process is stored in the memory as a user-created pattern, and the pre-existing pattern and the user-created pattern are used as necessary in the rough rolling process that is repeated thereafter. One of them can be selected as a master pattern, and when a ready-made pattern is selected, the rough kneading time can also be set arbitrarily, and the time allocated to each step of the selected ready-made pattern is The rough kneading time set above is calculated by dividing it by the total number of steps, and both the selected existing pattern and the set time are used as indicators, and when a user-created pattern is selected, the selected user-created pattern is It is characterized in that it is used as an index and one or more of the above-mentioned tea manufacturing elements are changed to complete one rough rolling process in each rolling and drying room. In addition, the tea roughening device of the present invention is capable of controlling each tea manufacturing element in the tea manufacturing process, such as the temperature of hot air sent into the rolling drying chamber, the amount of hot air, the rotation speed of the spindle on which the crusher and dredge are attached, and the position of the spindle. The tea manufacturing and rough rolling method is configured to complete the first rough rolling step by sequentially changing the steps as the process progresses, and the method comprises: a rolling drying room for rolling and drying the tea leaves; and a hot air generating means. , a means for supplying hot air into the rolling drying chamber, a main shaft rotatably disposed within the rolling drying chamber and equipped with a crushing hand for compressing the tea leaves in the rolling drying chamber and a dredge for scraping up the tea leaves, and each of the above-mentioned tea manufacturing elements. at least one operation unit for operating at least one of the tea manufacturing elements, a memory for storing a pattern serving as an indicator of the transition of the tea manufacturing elements during the rough rolling process, and a pattern stored in the memory. and a rough kneading time setting means for inputting an arbitrary rough kneading time into the control part, and the memory stores one or more predetermined patterns. In addition, when the user operates the operation section, the transition of the tea making elements due to the operation can be stored as a user-created pattern, and the control section can select any one of the pre-made patterns and the user-created pattern. In particular, when a ready-made pattern is selected, the time allocated to each step of the selected ready-made pattern is calculated by dividing the set coarse kneading time by the total number of steps. It is characterized in that the operation section can be controlled by determining the operation section.

Therefore, according to the present invention, there is no need for a skilled technician to be always nearby while the roughing process is repeated as in conventional roughing methods or devices, and even an inexperienced person can perform the process. be able to manage.

In other words, even if the number of ready-made patterns prepared is limited, the time allotted to each step of the ready-made patterns differs depending on the set rough rubbing time, so in the end, many pieces of ready-made patterns can be processed from one ready-made pattern. It is possible to obtain rough rolling conditions of a pattern, and it is possible to set more optimal rough rolling conditions according to the infinitely changing quality of steamed leaves, and the setting is easy.

In addition, the properties of fresh leaves and their response to steam are somewhat special.
In cases where ready-made patterns and their rough kneading time alone cannot be used, or when a skilled engineer is nearby and you wish to perform your own operations, or if you are inexperienced but would like to perform your own operations. If something goes wrong, each control element can continue to change in exactly the same pattern as the one they operated, so an experienced person can leave the situation with peace of mind, and an inexperienced person can continue to use his or her own technique. You will also be able to polish.

On the other hand, in terms of quality, it is possible to always obtain coarsely crushed leaves of a certain level of quality, regardless of the level of skill of the rough-milling process manager.

In the above-mentioned embodiment, the type of ready-made pattern was determined based on the type of steamed leaf quality, which is a combination of the quality of fresh leaves and the degree of steamed leaves. The contents of the pattern, that is, the specific control values for executing the roughening process can be made more reliable, and the process manager can easily decide which existing pattern to select. It can be done.

In addition, in the above explanation, each of the four drying rooms is explained as one for each independent roughing machine, but it is also possible to use a single roughing machine equipped with multiple roughing machines. Of course not.

In addition to those mentioned in this specification, the tea manufacturing factors that can be controlled by the present invention include those that affect the quality of tea leaves in the rough rolling process.

Furthermore, in the above embodiment, the operating units for setting each tea making element are those for the four rolling and drying chambers that are placed together on the control, but these are placed near each rolling and drying chamber. You can do it like this.
