Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an apparatus for manufacturing bean products, particularly for manufacturing bean products such as amanatto, bean paste, and bean confectionery, in which the beans are boiled and seasoning liquid is permeated. It relates to equipment used in the process.

Conventional technology Bean products such as amanatto, bean paste, and bean sweets are generally made by soaking the raw beans in water to remove the lye, boiling the beans from which the lye has been removed, and soaking the boiled beans in a sugar solution. Traditionally, the process of boiling the beans and the process of permeating the seasoning liquid into the beans were performed in separate containers, and the containers had to be transferred to move on to the next process. Ta. Moreover, in order to penetrate the sugar solution, conventional methods were to boil it down in a pot, concentrate under reduced pressure using a vacuum concentrator, or prepare multiple containers with different concentrations of sugar solution and immerse them in concentrated sugar solution one after another. In either case, it is difficult for the concentration of the sugar solution to become uniform throughout the whole, that is, the concentration tends to be higher in the lower layer than in the upper layer, which causes variations in the degree of penetration of the sugar solution into the beans, resulting in poor quality of the product. It tended to cause unevenness.

It is also known that a concentrator is loaded with baskets containing beans in several layers, and a stirring device is installed to stir the sugar solution, but because the basket is inside, the stirring effect cannot be spread over the whole area. However, this is not sufficient to make the sugar solution homogeneous.

In order to deal with the above-mentioned problems, a method has recently been developed in which a basket containing beans is placed in a heating container, the container is heated to boil the beans, and then a seasoning liquid is forced to circulate. According to this method, the process of boiling the beans and the process of permeating the seasoning liquid into the beans are performed in one container, so there is no need to transfer the beans, and because the seasoning liquid is forced to circulate, the degree of penetration of the seasoning liquid is controlled. equalize,
It has the advantage of producing an even product, but in the simmering process, the container used as the boiling pot must be replaced with a lid during the seasoning process to circulate the seasoning liquid before moving on to the next process. Alternatively, the opening or inlet must be opened and closed, which requires work and reduces work efficiency, and when the boiling process is finished and the lid or opening or inlet is opened, steam rises to the extent that it obstructs the view. In some cases, it was necessary to quickly remove the steam to prevent it from interfering with the work.

Problems to be Solved by the Invention This invention solves the above problems by making it possible to move from the boiling process to the seasoning liquid penetration process without replacing the lid or opening or closing the opening or inlet. The aim is to provide a manufacturing device for this purpose.

Means for Solving the Problems The apparatus of the present invention is therefore provided with a seasoning liquid concentration tank separate from the container used in the step of boiling the beans and impregnating the seasoning liquid.

That is, the present invention provides a boiling pot loaded with a basket containing beans, a heating means for heating the boiling pot, a concentrating device for concentrating a seasoning liquid, and a concentrating seasoning liquid discharged from the device. It is an object of the present invention to provide a device having a pump that supplies a boiling pot and a discharge pipe that sends a seasoning liquid discharged from the boiling pot to a concentrating device.

In the present invention, water may be supplied to the boiling pot in the boiling process when the lid is opened to load the basket, but preferably a water supply pipe is provided separately, and water is supplied to the boiling pot after boiling. The water can be discharged by providing a separate discharge pipe, or by using a seasoning liquid supply pipe or a discharge pipe.

The seasoning liquid sent to the boiling pot by the pump may be supplied from the upper part of the boiling pot and then discharged from the lower part, but preferably it is supplied from the lower part of the boiling pot and discharged from the upper part. desirable. This is because it becomes possible to drain the overflowing seasoning liquid to the concentrator using potential energy without using a pump.

A concentrating device is a device that increases the concentration by evaporating water when a seasoning liquid is sprayed from above and dripping, and in the above-mentioned type of device, a fan is used to suck out steam to promote evaporation. It is desirable to do so.

A shower 34 is attached to the end of the discharge pipe inside the tank. However, the shower 3
The sugar solution sprayed from 4 is concentrated by sucking out the steam by the blower 32. Note that the discharge pipe 31 is also connected to the water supply pipe 9 through a pipe 36. This is provided for cleaning the concentration tank 14 by opening the solenoid valve 37 provided in the pipe 36 at the end of the process.

The sugar solution tank 17 is a tank for storing the stock solution of sugar solution, and is provided with a lead-in pipe 39 from the introduction pipe 4 so that it is always kept warm when the manual valve 40 is open. By opening a manual valve 41, water can be replenished at any time. Note that the opening and closing of each of the solenoid valves described above is program-controlled by a control device consisting of a separately provided microcomputer.

Effect Next, each process performed by this apparatus will be explained.

Although it is preferable to perform the lye extraction step using a separate container, it can also be performed using this device. In the case of this device, the lid 1 of the boiling pot 2 is opened, a basket containing beans is loaded, and then the lid 1 is closed. Next, the solenoid valve 11 is opened by a signal from the control device, and water is injected into the boiling pot 2 through the water supply pipe 9.
At this time, the solenoid valve 12 is closed, so the boiling pot 2
Water is collected in the When a certain amount of water is reached and the basket is immersed, the solenoid valve 11 is closed.
After that, it is left as is for the required period and the lye is removed. After removing the lye, the solenoid valve 12 is opened and the lye is drained. Then, the solenoid valve 11 is opened again and water washing is performed.

The solenoid valve 12 is then closed and water is stored again. When the amount of water reaches a certain amount, the solenoid valve 11 is closed in the same manner as described above. Then, the solenoid valve 5 is opened and steam is introduced into the jacket 3 through the introduction pipe 4. This heats the boiling pot 2 and boils the beans. The cooled and liquefied water droplets are drained from the drain pipe 8.
However, the reduced pressure caused by this is constantly compensated for through the inlet pipe 4, and the boiling pot continues to be heated. The temperature inside the boiling pot is controlled by a temperature sensor 6, and maintained at a constant temperature by opening and closing a solenoid valve 5. When the beans are boiled after a certain period of time,
Solenoid valve 5 is closed. Next, the manual valve 43 is opened and the steam inside the jacket is discharged from the drain pipe. Then, the valve 12 is opened and the hot water in the boiling pot is discharged.

Next, the solenoid valves 26, 20, and 30 are opened, and the solenoid valves 19, 27, and 28 are closed, and the pump 13 is driven to pump the sugar solution from the sugar solution tank 17 to the branch pipe 22, the branch pipe 18, and the pipe. 10 and is supplied to the boiling pot 2 from the bottom. The supplied sugar solution increases in volume, and when the liquid level reaches the discharge port, the discharge pipe 31
The water is discharged from the shower 34 and sprayed from the shower 34. Then, it gradually accumulates in the concentration tank. When a certain amount of sugar solution has accumulated in the tank and a level sensor (not shown) detects this, the solenoid valve 26 is closed to stop the supply of sugar solution from the sugar solution tank 17, and the solenoid valve 27 is opened. The sugar solution in the concentration tank is sent to the boiling pot 2 via the branch pipe 23, pump 13, branch pipe 18, and pipe 10, and is circulated.

The valve 5 is opened before or after the circulation of the sugar solution starts or the supply of the sugar solution to the boiling pot 2, and the jacket 3 is opened.
Steam is sent again to heat boiler 2. Therefore, the circulating sugar solution is heated in the boiling pot and then dispersed in the concentration tank, and the steam generated here is sucked out by the blower 32, thereby gradually concentrating it. It is then boiled down in the boiling pot and permeated into the beans. The permeation of the sugar solution continues until there is no sugar solution in the concentration tank, at which point the valve 5 is closed and the supply of steam to the jacket 3 is stopped, and the valve 20 is closed and the valves 28 and 19 are opened. The residual sugar solution in the boiling pot is pipe 1.
0, and is returned to the sugar solution tank 17 via branch pipes 24 and 16. Pump 13 then stops.

Next, the lid 1 is opened, the basket is taken out, and the valves 11, 12, 37 and 28 are opened, and the boiling pot 2 and concentration tank 14 are cleaned. Wash water is discharged from the drain pipe 10.

Effects of the Invention According to the present invention, as described above, the process of boiling the beans and the process of permeating the seasoning liquid into the beans are performed in one boiling pot, and when moving from the boiling process to the process of permeating the seasoning liquid, You can move on to the next process without opening or closing the lid of the boiling pot or opening or closing the opening.
Work efficiency can be improved because there is no need to interrupt work or cause steam to build up and hinder work.
