[Problems to be solved by the invention]

What is common to such conventional emulsifying devices is that
That is, the emulsification pot is fixed. The reason is that the heat exchange device and the vacuum device are involved in the emulsification kettle.

Therefore, the supply of the stock solution to be emulsified to the emulsification tank is performed by a stock solution supply hose with a pump, and the discharge of the emulsified emulsion is performed by a suction and discharge hose with a suction pump.

In the conventional fixed emulsification kettle, there is a problem that the transfer of the emulsion is not easy because it is fixed, and that the quality of the emulsion is deteriorated due to air being mixed at the time of the transfer.

In recent years, as consumer preferences have diversified and a production system without stocks has been demanded, a small-quantity, multi-product production system has been demanded. With the frequent relocations, the above problems have become even more prominent.

On the other hand, emulsification is performed while heating or cooling the emulsification kettle. The heat energy becomes large due to repetition of heating and cooling, and there is a problem that the heat source capacity increases.

The present invention has been made in view of such a problem, and an object of the present invention is to provide an emulsifying apparatus capable of easily transferring an emulsified substance and saving energy, and an operation method thereof.

The solenoid valves (21, 22, 23, 24, 25, 26) and the temperature sensor 11 are connected to a control unit 60 by a microcomputer provided below the sensor chamber 55, and the inner pot 1b
Each of the solenoid valves is controlled to open and close by a command from the control unit 60 based on the temperature of the solenoid valve.

Next, a method for obtaining an emulsion using the apparatus of this embodiment will be described.

With the lid 3 lifted upward, the emulsification kettle 1 is moved to the side in the horizontal direction, and the inner pot 1b is removed. And inner pot 1b
The raw material of the emulsified product is put in the inside, and set again in the outer pot 1a.
Thereafter, the emulsification pot 1 is moved below the lid 3, the lid 3 is lowered and closed, and the inside of the inner pot 1 b is evacuated by the vacuum device 6.

In the heating step, first, the third to fifth solenoid valves (23, 24,
First and second solenoid valves (21,22,26) with 25) closed
open.

As a result, the heat medium (warm water) heated by the heating unit 8 passes through the liquid chamber 53 in the outer kettle 1a, and the heat medium outlet 5
Is discharged from At the same time, hot water is introduced into the space 51 between the outer kettle 1a and the inner kettle 1b. This heats the inner pot 1b, so that the raw material in the inner pot 1b is also indirectly heated. Since the empty space 51 is also filled with warm water, heat from the outer pot 1a is efficiently transmitted to the inner pot 1b.

During this time, the temperature of the inner pot 1b is detected by the temperature sensor 11, and is compared with the reference temperature by the control unit 60. In the initial state, since the inner pot 1b is not sufficiently heated, its temperature is lower than the reference temperature. The temperature of the inner pot 1b rises with time,
The temperature exceeds the reference temperature and becomes as close as possible to the temperature of hot water. Usually, the reference temperature is set to a value close to the temperature of the hot water.

When the temperature of the inner pot 1b is lower than the reference temperature, it means that the heat radiation amount of the hot water for heating the inner pot 1b is large, and conversely, the temperature of the discharged hot water is low. Therefore, in order to recycle such discharged water by heating, a large amount of heat is required for reheating. Therefore, the second solenoid valve 22 is kept open until the temperature of the inner pot 1b reaches the reference temperature, and the warm water that has passed through the liquid chamber 53 is directly discarded outside.

When the temperature of the inner pot 1b becomes higher than the reference temperature, the second solenoid valve 22 is closed by a command from the control unit 60, and the third solenoid valve 23 is closed.
Is opened, the discharged hot water is returned to the heating unit 8, reheated, and supplied to the emulsification pot 1 again. During this period, no water is supplied to the heating unit 8.

During the above, the raw materials in the inner pot 1b are stirred and mixed by the stirrer 2 to form an emulsion.

When the emulsification is completed, a cooling step is started. Here, the first,
Since the third solenoid valves (21, 23) are closed and the fourth solenoid valve 24 is opened, the heat medium (cooling water) cooled by the cooling unit 9 passes through the liquid chamber 53 in the outer kettle 1a, The gas is discharged from the discharge passage 10 via the second solenoid valve 22. Unless the inner pot 1b is removed from the outer pot 1a, the space 51 and its outlet 47 remain shut off, and the hot water used for heating remains in the empty space 51 between the outer pot 1a and the inner pot 1b. The sixth solenoid valve 26 is opened to supply a predetermined amount of cooling water, and the remaining warm water overflows from the upper part of the cavity 51 (the opening of the outer pot 1a) to release the cooling water. To be supplied. Then, when the cooling water passes through the liquid chamber 53, the cooling water in the space 51 is cooled, and further,
Through this, the inner pot 1b is efficiently cooled.

During this time, the temperature of the inner pot 1b is detected by the temperature sensor 11, and is compared with the reference temperature by the control unit 60. In the initial state, the temperature of the inner pot 1b is higher than the reference temperature because the inner pot 1b is not sufficiently cooled. The temperature of the inner pot 1b decreases with time,
When the temperature falls below the reference temperature, it becomes as close as possible to the temperature of the cooling water. Usually, the reference temperature is set to a value close to the temperature of the cooling water.

When the temperature of the inner pot 1b is higher than the reference temperature, it means that the amount of heat taken by the cooling water from the inner pot 1b is large, and conversely, the temperature of the discharged cooling water is high. Therefore, in order to cool and reuse such discharged water, a large amount of heat is required for re-cooling. Therefore, the second solenoid valve 22 is kept open until the temperature of the inner pot 1b reaches the reference temperature, and the cooling water that has passed through the liquid chamber 53 is discarded outside as it is.

When the temperature of the inner pot 1b becomes lower than the reference temperature, the second solenoid valve 22 is closed by a command from the control unit 60, and the fifth solenoid valve 25 is closed.
Is opened, the discharged cooling water is returned to the cooling unit 9, re-cooled, and supplied to the emulsification pot 1 again. During this period, no water is supplied to the cooling unit 9.

During the above, the raw materials in the inner pot 1b are stirred and mixed by the stirrer 2 to promote cooling of the emulsion.

When the cooling step is completed, the lid 3 is lifted upward, the emulsifying pot 1 is moved to the side, and the inner pot 1b is removed. As a result, the ring-shaped convex portion 52 of the inner pot 1b is separated from the O-ring 59 of the cylinder 58, so that the water in the space 51 falls into the cylinder 58 and is discharged from the outlet 47.

In the heating or cooling process, the temperature sensor
The temperature of 1b is monitored, each solenoid valve is opened and closed so that the inner pot 1b maintains a predetermined temperature, and after performing a heating process for a predetermined time, the solenoid valve is automatically switched to perform a cooling process.

As described above, in the present embodiment, when a large amount of heat is required for reheating and recooling, hot water and cooling water are discarded, so that 50% of conventional thermal energy can be saved.

In the first embodiment, the hot water is discarded until the temperature of the inner pot 1b exceeds the reference temperature, or the cooling water is discarded until the temperature becomes lower than the reference temperature. The temperature rise rate or the temperature fall rate may be detected from the change, and while the temperature rise rate or the temperature fall rate is large, the hot water or the cooling water may be discarded.

Further, in the initial stage of cooling in the cooling step, in order to minimize the amount of cooling water to be discarded to the outside, for example, the electromagnetic valve 27 is branched from the heat medium circulating path 7 between the electromagnetic valve 24 and the heat medium supply port 4 and If it is connected to the industrial water discharge path 7d via the water, the inner pot 1b can be cooled with the industrial water until the temperature of the inner pot 1b becomes lower than a certain standard, and the cooling unit is not re-cooled without discarding much of the cooling water from the cooling unit. It does not need to release much heat.

Second Embodiment Next, a second embodiment will be described.

In this embodiment, as shown in FIG. 4, in addition to the temperature sensor 11 and the control unit 60 provided in the first embodiment, a second temperature sensor 61 is provided between the heat medium discharge port 5 and the discharge path 10. And a second control unit 62 for receiving temperature information from the second temperature sensor 61. The first control unit 60 controls the first, third, fourth, fifth, and sixth solenoid valves (21, 23, 24, 25, 26), and the second control unit 62 The first, second, and third solenoid valves (21, 22, 23) are controlled.

Further, a second outlet 65 of the empty space 51 is provided above the outer hook 1a, and the overflow in the empty space 51 is discharged through a discharge passage 64 of the empty space.

Since the other points are the same as those of the first embodiment, the same reference numerals are given and the description is omitted.

Next, the operation of the second embodiment will be described. The operation is basically the same as that of the first embodiment.

In the heating step, first, in accordance with a command from the first control unit 60, the first, second, and sixth solenoid valves (21) are closed in a state where the third to fifth solenoid valves (23, 24, 25) are closed. , 22,26) opens.

Thereby, the hot water passes through the liquid chamber 53 and is discharged from the discharge path 10. At the same time, warm water is introduced into the space 51 and discharged from the second outlet 65. When the empty space 51 is full of warm water, the sixth solenoid valve 26 closes.

The second temperature sensor 61 detects the temperature of the hot water after the heating of the inner pot 1b, and the second control unit 62 compares the temperature with the reference temperature. While the temperature is lower than the reference temperature, the second solenoid valve 22 is turned on. Keep open. Then, when the temperature of the hot water after heating the inner pot 1b exceeds the reference temperature, the second solenoid valve 22 is closed, and the third solenoid valve 22 is closed.
Is opened. Therefore, the discharged hot water is returned to the heating unit 8, reheated, and supplied to the emulsification pot 1 again. During this period, no water is supplied to the heating unit 8.

During the stirring, the temperature of the inner pot 1b is monitored by the temperature sensor 11, and the solenoid valve 24 is opened and closed so that the inner pot 1b maintains a predetermined temperature. If the predetermined temperature continues for one hour, for example, it is determined that the emulsification has been completed, and the cooling process is started. Here, the first and third solenoid valves (21, 23) are closed and the fourth solenoid valve 24 is opened by a command from the first control unit 60, so that the cooling water passes through the liquid chamber 53 and the second
Is discharged from the discharge path 10 through the electromagnetic valve 22 of the first embodiment. Further, since the sixth electromagnetic valve 26 is also opened, the cooling water from the heat medium supply passage 7c pushes out the hot water from the space 51 through the space discharge passage 64. When the cooling water is replaced with the warm water, the sixth solenoid valve 26 closes.

The second temperature sensor 61 detects the temperature of the cooling water after cooling the inner pot 1b, and the second control unit 62 compares the temperature with the reference temperature. Keep open. When the temperature of the cooling water falls below the reference temperature, the second solenoid valve 22 is closed, and the third solenoid valve 23 is opened. Therefore, the discharged cooling water is returned to the cooling unit 9, re-cooled, and supplied to the emulsification pot 1 again. During this period, no water is supplied to the cooling unit 9.

〔The invention's effect〕

In the apparatus of the present invention, since the inner pot can be removed, the raw materials and the emulsion can be easily transferred, and it can be handled even by a woman with little skill. Therefore, the operation in the case where an emulsion production line is formed by arranging the raw material adjusting / supplying device, the main emulsifying device, and the device for filling the container of the emulsified product becomes quick and easy.

In addition, it is easy to switch types, and it is possible to quickly cope with small-quantity, multi-type production.
