Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel tea processing method and tea processing apparatus.

In detail, the amount of hot air sent into the drying chamber, which was said to be impossible to obtain a good product unless a skilled worker was always by the side of the machine and operated it according to the progress of the process. The transition of each control element in the tea making rough simulation process, such as the rotation speed of the spindle on which the pocket hand and the quick hand are attached, the position of the spindle, etc., is patterned based on the results of repeated trials, and the first rough finishing process is created. By using the pattern as an indicator to change the control elements, it is possible to obtain a product of a certain level of quality or higher, regardless of the skill level of the worker, and the roughening process of 1 can be changed to the first leaf punching process. The process is divided into several steps, and the user can set the time for the leaf beating process as desired, so that the straw beating time can be set differently from the leaf beating time specified in the pattern. In this case, the pattern is deformed, and the selection of the pattern allows for an almost error-free transition of the control elements, and at the same time, the arbitrary setting of the strawing time adapts to the infinite variety of tea leaves. The purpose of this invention is to provide a novel tea manufacturing method and a tea manufacturing roughing camouflage layer in which roughening conditions can be set. The tea processing process is
The tea leaves steamed in the previous process are gradually dried with hot air while being exposed to bare pressure in a drying room or sprinkled with hot air until the residual moisture content in the tea straw reaches approximately 50%. The important point is to keep the drying rate as constant as possible without over-drying while keeping it constant, and if you do this incorrectly, the yellowing of the hollyhock color, powdering, grassy smell, or stuffiness will occur. This leads to quality deterioration such as this.

Such a tea processing process is generally performed as follows.

That is, a main shaft is rotatably arranged in a quasi-drying chamber having a substantially cylindrical handling barrel, and a handle is placed on the main shaft to press the tea leaves against the handling barrel to apply bare pressure, and a handler is used to stir up the tea leaves and scatter flies. The tea leaves that have undergone the previous process are placed in the Minato drying chamber, and the spindle is rotated to apply pressure and spread to the tea leaves. It supplies hot air to gradually dry the tea leaves. Then, control elements such as the amount of tea leaves input into the drying chamber, the temperature and amount of hot air supplied into the drying chamber, the rotation speed of the spindle, the position of the leaf stopper, and the position of the spindle relative to the steering barrel are controlled as appropriate. By doing so, the best quality of life can be achieved. However, in such a tea processing process, it is not clear how each control element, for example, the hot air temperature, should be set to 0, or how it should change as the process progresses. Needless to say, it is impossible to set a certain standard and process it uniformly.

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 buds and stiff leaves, differences in tea varieties, differences in production areas, differences in annual rainfall and sunshine hours, and differences in the day before harvest. Due to differences in various conditions, such as differences in the weather, the condition of the fresh leaves changes from moment to moment, and furthermore, the condition of the tea leaves introduced into this roughening process changes in various ways depending on the steaming process in the previous process. This is because it is something you do. Therefore, if we were to say that if we should change each control element in the same way in the rough harvesting process this time because good results were obtained in the rough harvesting process in the previous year or the previous time, this is not necessarily the case. Sometimes you get good results, and sometimes you don't.

Furthermore, the tea making process is carried out in a battlefield-like environment, and it is not possible to keep records of the acidity of the airflow pattern, the duration of the opening, etc., which change at any time during the process of making tea. . The same holds true for other control elements in the roughening process, such as the rotational speed of the spindle and the position of the spindle.

From this point of view, in the tea processing industry, there is a back-grinding technician called a tea master who is always on hand at the grinding machine and monitors the progress of the grinding process, for example, checking the progress of the tea processing, The reality is that each control element during the roughening process, such as the change in the amount of hot air, is controlled based on experience and intuition, with reference to the feel of the product and the moisture level.

Furthermore, even if a skilled engineer is always nearby to control the volume of hot air, etc., the changes cannot be made exactly the same, and it is undeniable that there will be significant differences in the results each time. It is.

The tea processing method and tea processing rack apparatus of the present invention have been developed in view of these points, and the work to create ready-made patterns that serve as indicators of control element transitions requires the skills of skilled engineers or experiments. This is done depending on trial and trial data, but
In subsequent repeated processes, these patterns are used as indicators to change the control elements, thereby creating a new tea manufacturing and roughing method that makes it possible to mass-produce tea of high quality and uniform quality. The purpose of this project is to provide a unique device.

Also, even if you prepare ready-made patterns, the properties of tea leaves are ever-changing, so it is impossible to prepare all ready-made patterns that can be adapted to each one.
Even if a temporary pattern could be prepared, it would be difficult to select the most appropriate pattern.

Therefore, we made it possible to freely set the time for the beating process, which needs to be changed depending on the properties of the tea introduced into the steaming machine, especially the depth of steaming. It is an object of the present invention to provide a novel tea manufacturing and roughening method and a tea manufacturing and roughening device in which the pattern itself is appropriately changed when the time of the leaf beating process is different from that in the pattern. In this way, by selecting a ready-made pattern that matches the properties of the tea leaves and changing the control elements according to this pattern, any operator can perform roughing without making any mistakes. By being able to arbitrarily set the beating time, it becomes possible to adapt to various types of tea leaves with different characteristics.

The present invention will be described in detail below, but first, an example of a tea processing machine suitable for carrying out the present invention will be described.

FIG. 1 schematically shows a tea processing machine 1. As shown in FIG.

Reference numeral 3 denotes a frame of a tea processing machine, and the frame 3 is provided with a spindle drive unit 4 and a main shaft drive unit 5. The bare ear 4 has a gutter-like shape with both ends closed, and a take-out door 6 that can be opened and closed is formed at the lower part of the front side to take out the tea leaves after rough exploration. A main shaft 7 is rotatably provided inside the control barrel 4 and is rotated by the driving section 5 passing through the control barrel 4 in the direction of the ball. and draw 9
, 9, . . . are attached. It is a loss dissipation room installed at the upper end of the 8 cars 4 of the 1st river, and a window 11 that can be opened and closed is provided at the front, and a hot air blowing port 12 is opened and closed at the rear.

Reference numeral 13 denotes a steamed leaf pool located at the upper end exhaust port of the aggregation chamber 10, into which tea leaves are thrown until a predetermined weight is reached, and the lower doors 14 are shown by two-dot chain lines in FIG. When opened as shown, the tea leaves in the pool 13 are thrown into a drying chamber composed of a shank 4 and a porridge 10.

Note that this steamed leaf pool 13 is usually equipped with a tea leaf weight measuring device. Reference numeral 15 denotes a wire mesh that covers the upper end exhaust port of the diffusion chamber 10.

Reference numerals 16, 16, . . . are displacement adjustment dampers arranged inside the wire mesh 15 at the upper end of the foundation dispersion chamber 10, and the degree of opening and closing thereof is adjusted by a damper adjustment motor 17 fixed to the frame 3. It has become so.

Reference numeral 18 denotes a hot air guide formed on the rear side of the fly dispersal chamber 10, and one end thereof is connected to 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.

The heat exchange section 20 includes a furnace cylinder 23 and hot air passages 24, 24, . The hot air generated in the furnace tube 23 by the burner 25 passes through the hot air passages arranged in a labyrinth in the casing 22 and is discharged from the chimney 26. Incidentally, the burner 25 is provided with, for example, two nozzles that generate different amounts of heat (not shown), and these two nozzles are ignited in two, one is ignited, the other is ignited, 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 the air blowing fan 21.
Air enters the casing 22 from the air supply □ 27 that passes between the hot air outlet 19 and the casing 22, and is supplied into the air guide 18 from the hot air outlet 19. And the air is in the casing 22
When passing through the furnace tube 23 and hot air path 24, which are heated to high temperature,
, 24, . . . are heated and become hot air. Then, this hot air is supplied into the drying chamber from the hot air blowing rows 2, 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 roughening process using the roughening machine 1 as described above is carried out as follows.

A predetermined amount of tea leaves that have completed the steaming process are introduced into the steamed leaf pool 13, and when the doors 14, 14 of the steamed leaf pool 13 are opened, the tea leaves are introduced into the drying room consisting of the drying room 4 and the nada dispersion room 10. Injected. The hot air generated by the hot air generator 2 passes through the hot air guide 18 to the hot air inlets 12, 12, . . .
・Supplied into the drying room. Then, the main shaft 7 is rotated, and the tea leaves are pressed and twisted against the bottom by the handles 8, 8, . It will be dissipated. Then, the tea leaves are twisted and scattered with flies and come into contact with hot air, gradually drying and undergoing the roughening process. The above operation is continued until the residual moisture 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 conveyor 29 below. , then sent to the bare twisting process. As mentioned earlier, the tea processing process described above has the significance of drying the tea leaves steamed in the previous process until the residual moisture content is reduced to about 50%.
It is not sufficient to simply reduce the residual moisture content to about 50%, but it must be done in a way that does not cause deterioration in the quality of the tea leaves, such as their color and aroma.

In order to do this, each control element in the tea making and roughing process, such as the temperature of the hot air supplied to the drying chamber, the amount of hot air, the rotation speed of the spindle, and the position of the spindle, must be adjusted according to the progress of the process. It must be progressed sequentially. Therefore, the means by which these control elements are controlled in the tea milling machine 1 will be explained by giving an example of these means. First, the temperature of the hot air supplied to the bare dry room 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 to detect the temperature of the hot air blown into the bare dry room, and the burn-up degree of the burner is determined based on the difference between this value and the target value at that time. In other words, one of three modes of adjustment may be selected: both of the two nozzles are ignited, only one of them is ignited, and only the other is ignited. The amount of hot air supplied into the drying chamber depends on the number of rotations 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, the air supply fan 21 and the heat exchange section 20. It can be controlled by adjusting the opening/closing degree of the damper disposed between the air supply □27 and the opening/closing degree of the damper.

The rotational speed of the main shaft 7 can be controlled, for example, by a mechanism shown in FIG.

The frame of the main shaft drive section 5 includes a reduction gear 31 fixed on the frame 30, and an output shaft (not shown) of the reduction gear 31.

) is connected to the main shaft 7 directly or via a universal joint or the like. Reference numeral 32 denotes a reduction gear booley, which is fixed to the input shaft 33 of the reduction gear 31.

Reference numeral 34 denotes a speed change base which is rotatably supported by a frame portion 35, and the main shaft drive motor 3 is mounted on the speed change base 34.

is installed, and a V-belt 39 is installed between the variable adjustable pulley 38 and the reduction gear pulley 32. This variable pulley 38 is formed by two members in which a groove for suspending the belt is joined by elastic means, and when the speed change base 34 rotates in the direction of the solid line arrow and the pulley 38 moves away from the other pulley 32. , the pressing force by the V-belt 39 acts between the two members forming the groove to widen the gap between them. As a result, the diameter of the groove in which the belt is hung becomes smaller. Furthermore, when the speed change base 34 rotates in the direction of the dotted arrow, the two members forming the groove move toward each other by the elastic pressure means, and as a result, the diameter of the groove increases. Reference numeral 40 denotes a speed change rod rotatably supported by an intermediate portion 41 of the frame.

A sliding pin 42 is provided at one swing end of the speed change rod 40, and this sliding pin 42 can freely slide into the largest sliding hole 43 provided at the free end of the speed change base 34. is engaged with. Note that the free end of the speed change base 34 is connected to the spring 4.
4, it is constantly pulled in the direction of the line arrow. Shift. The other swinging end of the pad 40 is formed with the largest sliding hole 45 . A control motor 46 is fixed on the frame 30 and swings the control rod 49 via a rotation transmission system 47 and a reduction gear 48.

A roller 50 is rotatably provided at the swinging end of the control rod 49, and the roller 50 is slidably engaged with the sliding hole 45 of the speed change rod 40. When the control rod 49 is swung by the control motor 46, 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 light pulley 38 is adjusted in accordance with the direction. By increasing or decreasing the rotation speed applied to the input shaft 33 of the reduction gear 31 via the pulley 32, the rotation speed of the main shaft 7 is changed.

The relative position of the main shaft 7 with respect to the base can be adjusted by using a mechanism as shown in FIGS. 4 to 6, for example.

Reference numeral 51 designates disc-shaped bearing discs that are rotatably supported by the frame 3 at the positions on both side ends of the shell body 4.

A bearing portion 52 for receiving the end of the main shaft 7 is formed at a position eccentric from the rotation center of the bearing disk 51.
2 supports the end of the main shaft 7. Reference numeral 53 denotes 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.

55 is a control motor 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.
This pin 58 is slidably engaged with the outermost hole 54 of the aforementioned change rod 53. In addition, as mentioned above, the bearing plate 6
1. The change rod 53 and the control rod 57 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 disc 61. move.

Accordingly, the bearing disk 51 that 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 position of the main shaft 7 in this manner, the degree of bare pressure on the tea leaves is changed. For example, when the main shaft 7 is at the position shown by the solid line in FIG. 4, the operator 8 draws a trajectory shown by the dotted line A, but when the main shaft 7 is at the position shown by the two-dot chain line in FIG. , operator 8 is 2
A trajectory indicated by the dotted chain line B is drawn, and the degree of pressure applied to the tea leaves by the handle 8, which is rotated in the direction indicated by the arrow C, is increased compared to when the trajectory A is drawn. Therefore, by appropriately changing the position of the main shaft 7, the optimum degree of bare pressure can be selected. Reference numeral 59 denotes a leaf stopper plate disposed approximately in the upper center of the rock-spreading room 10 so as to traverse it in the longitudinal direction.

The leaf stopper plate 59 is connected to a control motor 61 via rings 60, 602, and 603, and can be rotated about a shaft 62 as shown by the two-dot chain line in FIG. There is. Then, depending on the position of the leaf stopping plate 59,
Good hand 9, 9,... The trajectory of the stirred tea leaves changes due to... That is, the code "5" of the Aoi stopper plate in FIG.
The locus will be drawn as shown by the arrows I to D corresponding to the edicts I to II added to "9". Then, as the trajectory changes from A to II, the tea leaves fall directly below the main shaft 7, and the degree of rubbing of the tea leaves increases. Figure 8 is a front view of the control panel.

3 is also connected to the input/output ports 8 through respective latch circuits 95, 95. - Therefore, the tea manufacturing process using the tea manufacturing rough camouflage layer as described above is performed as follows.

First, it is determined whether control elements such as air volume and spindle rotation speed are to be changed manually or according to established patterns. In the case of manual operation, the program selection switch 65 is set to the "manual" position, and in the case of transition according to a predefined pattern, an appropriate predefined pattern of "1" to "5" is selected according to the properties of the tea leaves. Select. In the case of manual control, the transition of the control elements is all done manually, and in the case of pattern control, the transition of each control element is patterned.
The control elements are stored in the PROM, and each control element will be transitioned according to the selected pattern. FIGS. 11 and 12 show an example of the above-mentioned pattern, and show the hot air volume pattern when "2, Wakame, Ichibancha" is selected by the program selection switch 65, for example.

11 and 12 show the same pattern; FIG. 11 is shown numerically, and FIG. 12 is shown graphically. In this embodiment, the entire roughening process of 1 is divided into 29 steps, and each step is assigned one memory address (in the EPROM), for example from "00 first control" to "IC" address. If the control target value of the control element at each memory address is, for example, hot air volume, "114/mln" at the 00th location, "138/min" at the 01th location, ... "IBJ "4" in the address
"2/min" and "42/mln" are written at the "IC" address.

Therefore, for example, if the pattern "2, Wakame, Ichibancha" is selected, the amount of hot air supplied into the drying chamber will change according to pattern a in Figure 11 (the transition shown by the solid line in Figure 12). be done. Of course, the other control elements written in the pattern are the same. Next, the pushbuttons 67 and 69 are operated to set the roughening time and the leaf beating time.

In this embodiment, the time required for coarse-graining is not specified in the existing pattern, but only the number of steps, 29, is specified.

Therefore, the user determines the rough time by operating the push buttons 67, 672. Then, the set roughness time is divided by the number of steps, 29, to calculate the time per step. For example, if the rough time is set to 44 minutes, 1
The time per step is 44 (minutes) ÷ 29 (steps)
This means that it is 1.25 (minutes).

Therefore, pattern a in Figure 11 is selected, and the roughness time is 4.
If it is set to 4 minutes, the hot air volume will be controlled according to the value stored in ``00'' until 1.52 minutes have passed from the start of rough operation, and from 1.52 minutes to 3.03 minutes, it will be controlled according to the value stored in ``01''. Depending on the value of the address, from 3.03 minutes to 4.55 minutes, control is performed according to the value of address 02, and so on, until control is controlled by the value of address ``IC'' between 42.48 minutes and 44 minutes. This completes one roughening process. Next, push buttons 79, 792 are operated to set the leaf beating time.

In this example, the entire roughening process of 1 consists of 4 steps:
That is, the process is divided into a straw beating process, a first shading process, a second shading process, and a third shading process, and the above-mentioned 29 steps are assigned to each of these processes. In pattern a in Figure 11, 8 steps from 00 to 07 are in the leaf beating process, 5 steps from 08 to 1 are in the 1st manipulating process, and ” From the address “15
The 9 steps up to the first address are assigned to the second operation process, the 7 steps from address 16 to the IC address are assigned to the third input process, and so on.The total 29 steps are divided and assigned to each process. ing. Then, once the leaf beating time is set, the set leaf beating time is divided by the time per step described above, and the answer is taken as the number of steps in the leaf beating process set by the user. For example, if the rough harvest time is set to 44 minutes and the leaf beating time is 12 minutes, the number of leaf beating steps set by the user is 44 (minutes) 12 (minutes) ÷ 2 skin steps) 27.9, which is 8 steps. will be allocated.

This is the same as the number of steps 8 assigned to the leaf beating process in pattern a, so in such a case, the control elements are changed as is in the selected existing pattern. Inside the microcomputer, the contents of address ``IC'' from address 00 are transferred as is to the RAM working area. If the leaf beating time (converted into the number of steps) set by the user is longer or shorter than the leaf beating time in the selected existing pattern, the selected pattern will essentially be rewritten.

Next, the flow of the program in such a case, including the case where the above-described pattern is not changed, will be explained using the flowchart of FIG. 10 and FIGS. 11 and 12. '

(i) Determine whether the comparison results in (h) are equal or not. If they are equal, proceed to the next step; if not, jump to (-). (i
) Transfer the ready-made pattern (selected pattern) read in step (g) directly to the working area of the RAM and proceed to the next step.

(k) Start roughing using the selected pattern as an index.

With this, for example, regarding the air volume, it changes according to the numerical value shown in pattern a in FIG. (
1) Determine whether the answer obtained by subtracting the number of steps within the pattern from the number of steps set by the user is negative. If yes, proceed to the next step; if no, proceed to (q). move on.

(m) Transfer the number of steps corresponding to the number of leaf beating steps set by the user from the first step of the pattern of the leaf beating process in the selected pattern to the working area of the RAM, and proceed to the next step. For example, if the selected pattern is pattern a in Figure 11, and the setting time is 44 minutes and the beating time is 6 minutes, the number of steps set by the user is 4 steps) 6 (minutes) ÷ 2 steps ) = 4 (step), therefore, the contents from the first position of ``00'' to the first position of ``03'' are RA.
The first to fourth steps in the working area of M are sequentially transferred to the corresponding address.

(n) Transfer the pattern of the first simulation step in the selected pattern as it is to the RAM working area and proceed to the next step.

That is, the contents from address 08 to address 1 in pattern a are sequentially transferred to addresses corresponding to steps 5 to 9 in the working area of the RAM.

(o) The content of the first step of the pattern of the second inputting process in the selected pattern is changed by the number of minus steps (number of user punching steps (4) - number of leaf punching steps in the pattern '81 = -4, i.e. Transfer the 4 steps to the working area of RAM, and transfer the pattern of the second embedding process as it is to the working area of RAM.
Move on.

That is, the contents of the "OD" address are transferred to the addresses corresponding to the 10th to 13th steps of the RAM working area, and then the contents from the "OD" address to the "15th address" are transferred to the RAM working area in order. Transfer to addresses corresponding to the 14th to 22nd steps of the area (p) Transfer the pattern of the third operation step in the selected pattern as it is to the RAM working area, (k)
Proceed to.

In other words, the contents from the 16th address to the IC address are sequentially stored in the RAM working area from the 23rd step to the 2nd step.
Transfer to the address corresponding to up to the 9th step and proceed to (k).

In this case, the Z “selection pattern” in (k) is (m
) to (p), that is, the rewritten pattern b in FIG.
The transition is made in a pattern in which the solid line al in the figure is replaced with a dotted line b. (q) After transferring the pattern of the leaf beating process in the selected pattern as it is to the RAM working area, the contents of the last step of the pattern are transferred to the RAM by the number of increased steps (user leaf beating step selection - number of leaf beating steps in the pattern). Continuously transfer to the working area and proceed to the next step.

For example, if the set leaf beating time is 18 minutes, the number of user straw beating steps is 144 (boats) 18 (minutes) ÷ 2g steps) = 12 (steps), which means that the number of leaf beating steps in the pattern is 8, which means 4. The number of steps increases, and these four steps become the number of increased steps.

Therefore, the contents of pattern a from address 00 to address 07 are sequentially transferred to addresses corresponding to steps 1 to 8 of the RAM working area, and then the contents of address 07 are transferred to addresses corresponding to steps 1 to 8 of the RAM working area. It is transferred to the address corresponding to the 9th step to the 12th step in the RAM working area. (r) The pattern of the first embedding process of the selected pattern is transferred as it is to the RAM working area and proceeds to the next step. That is, "08 The contents from the first address to the only address are sequentially displayed in steps 13 to 17 of the OAM working area.
Transfer to the address corresponding to the step.

(s) Transfer the pattern of the second operation step in the selected pattern to the RAM working area in order, except for the last step corresponding to the number of plus steps, and proceed to the next step.

That is, from the address "Blood" that constitutes the second stripping process pattern, the number of steps corresponding to the above-mentioned plus steps (4
Step 1)
The contents from address ``Blood'' to address ``11'' are sequentially transferred to addresses corresponding to steps 18 to 22 in the RAM working area, except for ``number 5''.

(t) Transfer the pattern of the third manipulation step in the selected pattern to the RAM working area as it is, and proceed to (k). That is, the data is sequentially transferred to the addresses corresponding to steps 23 to 29 in the content RAM working area from address 16 to address IC, and the process proceeds to (k).

In this case, the "selection pattern" in (k) is (q)
The pattern a modified by ~(t), that is, the first
This is the rewriting pattern c in FIG. 1, and therefore, the air flow rate changes according to the pattern in which the solid line a2 in FIG. 12 is replaced with the dashed line c. As is clear from the above description, in the present invention, several ready-made patterns are prepared that serve as indicators of the transition of control elements in the tea processing and roughening process, and these can be selected as appropriate. ,1
The roughing process is divided into several processes including the first leaf beating process, and the time for the leaf beating process can be set arbitrarily. When the leaf beating time is set, the selected pattern itself is transformed accordingly, so by selecting a ready-made pattern, it is possible to make a transition of control elements that is almost error-free. By arbitrarily setting the beating time, it is possible to set roughening conditions that correspond to infinite variations in tea leaves, greatly expanding the range of application.

Furthermore, the ability to arbitrarily set the breakout time further expands the applicability. In the above embodiment, the case where the control element that changes depending on the pattern is the hot air volume, but in addition, the control element that changes depending on the pattern is the spindle rotation speed, the spindle position,
Of course, the temperature of hot air, the temperature of tea, etc. may be controlled as appropriate according to the pattern. Further, in the above embodiment, one roughening process is further divided into four processes, but the number of divisions is not limited to four, and may be at least or more than that.

At the same time, the rough kneading time and the leaf beating time can be set arbitrarily, and each of the pre-made patterns divides the rough kneading process from the start to the end into multiple steps, and further divides the entire process into several groups. For example, groups are made to correspond to each stage of the rough rolling process such as leaf beating, first rolling, second rolling, and third rolling, and the values of control elements at each step are described in a form that directly or indirectly indicates The time allocated to each step is calculated by dividing the set rough kneading time by the total number of steps, and when the leaf beating time is set arbitrarily, the set time is allocated to one step. The number of steps in the leafing stage is calculated by dividing by the time given, and the number of steps is compared with the number of steps in the leafing stage in the selected pattern.
