Generally, to make tofu, the dried beans are first screened, cleaned the surface of the soybeans, and then they are called by immersing them in cold water.

The temperature of the room is about 28 hours - 30 degrees Celsius for about 10 hours. The so called beans expand more than twice the weight of dry beans.

Then, the soaked beans are ground using a tofu machine, and then filtered using soy sauce filter using a filter.

The thus obtained soymilk is heated by high temperature steam, is received by using a container, and the coagulant is sprayed on the soymilk while being cooled to a predetermined temperature to solidify the soymilk.

The tofu is produced by agglomerating the coagulated soymilk, compressing it with a compactor, shaping it in a molding machine and cutting it to a proper size.

This method of producing tofu has a problem in that a lot of scum such as a scum is generated and the generation of waste water is increased.

In addition, since most of the work is done manually by an operator, there is an unsanitary process, which takes a long time in the manufacturing process, which is a factor of deteriorating the productivity.

1 is a front view of a head manufacturing apparatus according to an embodiment of the present invention.
2 is a view showing a head manufacturing process according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a head manufacturing apparatus according to an embodiment of the present invention, and reference numeral 2 denotes a first stirring tank.

The first stirring tank 2 is provided at its upper portion with a stirring motor 4 for stirring the contents to be contained therein. The stirring motor 6 is equipped with a stirring blade 6 at an end portion of a stirring shaft extending inside the stirring tank. Is rotatably installed.

The stirring motor 4 is firmly installed on the upper side of the first stirring tank 2 through a support member 8 and is provided at a lower side of the first stirring tank 2 at a high temperature A steam spray nozzle 10 for spraying the steam of the first stirring tank to the inside of the first stirring tank.

The contents inside the first agitating tank 2 can be heated by the steam injected from the steam injection nozzle 10. The temperature of the steam coming from the steam injection nozzle 10 is about 90-95 degrees Celsius.

In the first stirring tank 2, soybean powder is mixed with water and stirred. To this end, a water supply nozzle 12 for supplying water to the upper part of the first stirring tank 2 is installed, A channel 14 is connected to the lower part of the first stirring tank 2 so that the contents contained in the first stirring tank 2 can be discharged.

The soybean powder used in the present invention preferably has a particle size of 300 mesh, and the amount of the feed once is about 30 kg.

The first stirring tank (2) is made of a structure in which the lower side is gradually narrowed so that the contents can be smoothly discharged to the lower side.

A conduit (14) connected to the lower outlet of the first agitating tank (2) is provided with a lock valve (16) which can allow or block the movement of the contents.

The conduit 14 is connected to the inlet side of the flow control valve 18 which discharges the contents coming out through the lock valve 16 by a predetermined amount.

The flow control valve 18 may be of various types, such as a time control type valve for controlling the opening / closing time of the outlet side, or a pressure control type valve for controlling the ejection pressure.

The container 20 is positioned at a certain distance below the flow control valve 18. The container 20 can be fed to a position defined by an automatic feeding means C such as a conveyor.

Since the container 20 has a shape capable of forming a head shape, it has a structure that forms a substantially rectangular internal space, and is a container made of a synthetic resin.

Another flow path 22 is connected to the flow control valve 18 so as to communicate with the lower side of the second agitating tank 24.

The second stirring tank 24 stirs the adduct added in the manufacture of the tofu. As the adduct, the starch fermentation enzyme for the fermentation of soybean powder for making tofu, and the mineral for the coagulation of the tofu, Lt; / RTI >

Therefore, the stirring motor 26 is fixed through the support member 28 to rotate the stirring blade 30.

Adjuncts that have been stirred in the second stirring tank 24 are transferred to the flow control valve 18 through the pipeline 22. The blocking valve 32 is provided below the stirring tank as a means for blocking the transfer while stirring. Respectively.

The steam injection nozzle 10, the lock valves 16 and 32, the flow rate control valve 18 and the like are not shown, but the operation time and the like can be controlled in the controller. Such automatic control of the valve flow can be applied to a technique commonly used in this field. However, it is needless to say that it is possible to manually operate it by the operator.

When the tofu powder stirred in the container 20 is filled, the opening side of the container is covered with a resin film, and the film f is fused by the film fuser 34.

The film fuser 34 presses the film f released from the roll r on which the film f is rolled by the heater h so that the film is fused to the peripheral flange portion of the container 20 Such a film fusing method is the same as or similar to the method used in general, so that detailed description is omitted.

The head manufacturing apparatus thus manufactured is manufactured through a process as shown in FIG. 2 to produce a head.

That is, the prepared raw bean powder and water are put into the first stirring tank 2, and the primary stirring is started by the step of stirring the raw material by driving the stirring motor 4.

In this process, 70 liters of water and 30 kg of soybean powder having a particle size of 300 mesh or more were put and stirred, and smooth stirring could proceed and uniform stirring could proceed.

It is also preferable to increase the degree of saturation roll of the stirred bean product through the secondary stirring process. In the secondary stirring, the pump (p) is provided outside the primary stirring tank (2), and the inlet side and the outlet side of the pump are connected to the lower and upper portions of the one-way stirring tank (2) .

When the secondary agitation is completed, a step of injecting hot steam into the primary agitation tank 2 through the steam injection nozzle 10 to warm the stirred beans.

When the heating process is performed in this manner, the stirred bean in the primary agitation tank 2 is in a state similar to soybean milk.

When the heating process is completed, the sprayed steam is cut off and natural cooling is performed. At this time, after cooling from about 70 ° C. to 60 ° C., when the cooling process is completed, the lock valve 16 is opened to discharge the beans cooled in the temperature range, (20) is filled with bean sprouts.

The reason for performing the cooling process is to cool the container 20 to a temperature that does not cause deformation of the container because the container 20 is made of synthetic resin.

It was also found through experimentation that the reaction of the enzyme occurs best in the above temperature range.

At this time, since the bean is supplied through the flow control valve 18, the bean is filled in the container 20 as much as the determined amount.

During the above processes, the process of stirring the adduct to be added to the head in the second stirring tank 24 also proceeds.

That is, minerals (or magnesium chloride) are added to the tank as starch fermentation enzymes and coagulants as additives, stirred and then fed to the container 20 while the beans are being filled in the container 20.

In this process, the bean sprouts coming from the first stirring tank 2 and the adducts coming from the second stirring tank 24 are supplied to the container 20 located below the flow control valve 18, Mixed.

Once the filling process is completed with the container 20, if the reaction time is set so that the enzyme and the mineral react with each other for about 30 minutes, they gradually coagulate in the container 20.

When the solidification process is completed, the container 20 is moved to the film fuser 34 of the packaging part using the automatic feeding device C to fuse the film f to the upper side of the container 20, . The film fusing process can be carried out in a conventional manner.

When the film fusing process is completed, the microbial propagation is inhibited through the sterilization process, the freshness of the product is maintained through the cooling process, and the production of the tofu is completed through the metallic foreign substance inspecting process. These processes can be carried out in a manner similar to the processes normally carried out.
