Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an apparatus for producing bean curd, and more particularly to an apparatus for producing yuba (soybean yuba), which can prevent a coagulated thin film from adhering to a soybean milk tank.

[Prior art] Yuba, which is obtained by heating soy milk and collecting the coagulated thin film that forms on the liquid surface, is widely known as a traditional food in Japan. It is also attracting attention as a health food rich in vegetable fats.

Conventionally, to produce yuba, soybeans are soaked in water, then ground and filtered to obtain soymilk, which is poured into a heating tank and heated at a temperature of about 90°C for 10 to 15 minutes. The method involved scooping up the solidified thin film that formed on the liquid surface one by one with a stick and drying it.

However, in such a classical method for producing S leaves, the operation is complicated, and furthermore, a thin solidified film is formed on the liquid surface and scooped up one by one, which is time-consuming and difficult to produce continuously.

Therefore, in the past, various improvements have been made to the apparatus for producing yuba (Japanese Patent Application Laid-open No. 51-22844, No. 54-80448, No. 55-50872).

For example, Japanese Patent Laid-Open No. 51-22844 discloses the following apparatus for producing yuba.

That is, as shown in FIG. 8, soybean milk 12 is poured into the soybean milk tank 10, and a heating device 8I114 is provided at the bottom of the soybean milk tank 10.

The liquid surface 12a of the soybean milk 12 in the soybean milk tank 10 is covered with a film 16 having water vapor permeability.

In this state, the soybean milk 12 in the soybean milk tank 10 is heated by the heating unit 14.
When the soybean milk 12 is heated, a thin coagulated film 18 is formed on the liquid surface 12a of the soymilk 12.

The coagulated R film 18 is adhered to the film 16 with an appropriate adhesion force, and when the film 16 is pulled up, the coagulated thin film 18 is also pulled up.
After being pulled up, the solidified thin film 18 easily peels off naturally and is subjected to a subsequent drying process.

Therefore, according to this method, it becomes easy to pull up the solidified thin film, and it also becomes possible to achieve continuous production.

[Problems to be Solved by the Invention] Problems in the Prior Art However, in this type of yuba manufacturing apparatus, there is a problem in that it takes a long time to form a coagulated thin film on the surface of the soybean milk liquid. there were.

In other words, the formation of a coagulated thin film on the surface of the soybean milk liquid is thought to be due to the evaporation of water at the liquid surface, which increases the protein Fj11 degrees at the liquid surface, causing mutual reactions. However, once the surface of the soybean milk is coated with a film, even if the film has excellent water vapor permeability,
Evaporation of water from the liquid surface is significantly delayed, and if the soymilk concentration is constant, it will take several times as long to form a coagulated thin film.

Furthermore, in the conventional method of retaining soymilk in a soybean milk tank and heating the soymilk, as the number of coagulated thin films taken out increases, the composition of the residual liquid changes, making it impossible to maintain a constant quality. In other words, soy milk contains a mixture of components that coagulate easily and components that tend to remain soluble in the residual liquid, and as all of the coagulated milk is removed, the non-coagulability of the residual soy milk increases. The concentration of the ingredients becomes extremely high.

Furthermore, the long-term heating also caused changes in the components of the soymilk itself, making it impossible to continuously collect high-quality coagulated thin films.

As a result, the quality of the dried bean paste obtained by collecting and drying the coagulated thin film is not stable, resulting in low product value.

OBJECTS OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and its purpose is to provide an apparatus for efficiently producing bean curd of consistent quality.

[Means for Solving the Problems] In order to achieve the above object, the yuba manufacturing apparatus according to the first invention of the present application is provided with a coating layer on the inner wall of the soybean milk tank to prevent the solidified thin film from adhering to the wall surface. There is.

Furthermore, a recessed portion is provided in at least a portion of the peripheral edge of the bottom surface of the soybean milk tank.

The soybean milk tank is characterized in that soybean milk is poured into the soybean milk tank in a thin layer.

Further, in the yuba manufacturing apparatus according to the second invention of the present application, a recess is provided in at least a part of the peripheral edge of the bottom of the soybean milk tank, and a film is removably disposed in close contact with the soybean milk tank.

The method is characterized in that soybean milk is injected onto the film in a WI layer.

[Operation] Since the first invention of the present application has the above means, the soymilk poured into the soybean milk tank in a thin layer is heated by the heating section,
It solidifies into a thin film. At this time, only a thin layer of suspended soymilk that forms a single sheet of yuba is poured into the soybean tank, and as in the past, the soymilk is heated and a thin layer of coagulation is collected from the liquid surface. Unlike conventional methods, the concentration of non-coagulated components in the residual liquid does not increase, or the soy milk itself deteriorates due to long-term heating, and it is possible to produce bean curd that is always stable and of a constant quality. becomes possible.

Furthermore, since the soymilk is poured into the soybean milk tank and the surface of the soybean milk is not coated with a film or the like, water evaporation is not hindered and a thin solidified film is formed in an extremely short period of time.

Unlike conventional production equipment, the coating layer prevents the coagulation thin film from adhering to the inner wall of the soybean milk tank, and moreover, some soymilk remains uncoagulated in the recess provided at the periphery of the bottom of the soybean milk tank. The coagulated thin film can be peeled off from the soybean milk bath very easily.

On the other hand, since the apparatus for producing tofu skin according to the second invention of the present application has the above-described means, it is possible to form solidified thin films one by one in the same manner as in the first invention, and to always produce tofu skin with a stable and constant quality. Become.

In addition, soy milk is formed on a film that is placed in close contact with the soy milk tank, and the film does not cover the surface of the soy milk liquid, so it does not prevent water evaporation and coagulates and forms IS in a very short time. .

Then, the coagulated thin film formed on the film is extremely easily peeled off from the soybean milk tank together with the film.

In addition, at the periphery of the solidified thin film formed on the film,
A small amount of uncoagulated soymilk remains in the concave portion of the soybean milk tank, and the coagulated 7m membrane and the film can be easily separated from this portion.

As explained above, according to the inventions of the present application, it is possible to form a coagulated thin film one by one in the soybean milk tank, so it is possible to produce bean curds of consistently stable quality in a short time, and the production is also easy. becomes.
