Abstract

A process for producing soybean milk and a process for producing tofu whereby the whole soybeans employed can be converted into soybean milk or tofu without forming any okara (bean curd less), thus enabling economical production without forming any industrial waste, and soybean milk or tofu having an improved soybean flavor and an elevated dietary fiber content, compared with conventional products, can be obtained; and an apparatus for producing tofu. This process involves the step of preparing a soybean powder wherein soybeans are husked and milled to give a size of 50 νm or less; the step of preparing go by mixing the soybean powder obtained in the above step and water in an agitator; and the boiling step wherein the go prepared in the above step is boiled in a pressure cooker so as to dissolve fibrous matters contained in the go, thereby giving soybean milk.

Description

TECHNICAL FIELD The present invention relates to a method for producing soymilk, a method for producing tofu, and an apparatus for producing tofu. Conventionally, when manufacturing soy milk or tofu, soybeans are washed, immersed in water, crushed, boiled, and filtered over approximately 13 hours. The tofu is manufactured by cooling.

In the conventional method of producing soy milk and tofu, about 30% of soybeans used in filtration are generated as okara during filtration, and the waste must be treated as industrial waste, which increases costs. At the same time, about 30% of the soybeans used became okara and wasted wastefully, which was uneconomical.

In view of the above-mentioned conventional disadvantages, the present invention eliminates the generation of soybeans during the production of soymilk and tofu, and enables the entire amount of soybeans to be used to be soymilk and tofu.It is economical and eliminates the generation of industrial waste, and An object of the present invention is to provide a method for producing soymilk, a method for producing tofu, and an apparatus for producing tofu, which have a texture similar to that of conventional soymilk and tofu, and have an increased body and dietary fiber of soybean.

The above and other objects and novel features of the present invention will become more fully apparent from the following description when read in conjunction with the accompanying drawings.

However, the drawings are merely for explanation and do not limit the technical scope of the present invention. DISCLOSURE OF THE INVENTION In order to achieve the above object, the present invention provides a soybean powder manufacturing process for removing soybean hulls and manufacturing soybean powder crushed to 50 microns or less, and a soybean manufactured by this soybean powder manufacturing process. Kure juice that is made by mixing powder and water with a stirrer The soymilk production method comprises a production process, and a boiling process in which the wusu juice produced in the kusui production process is boiled in a pressure boiling kettle into soymilk so as to dissolve the fiber contained therein. ing.

Further, the present invention provides a soybean powder production process for producing soybean powder obtained by removing soybean hulls and pulverizing the soybean powder to 50 microns or less, and mixing the soybean powder produced in this soybean powder production process with water with a stirrer. And a boiling step of boiling the gou juice produced in the gou juice producing step into a soy milk by boiling it in a pressure boiling kettle so as to dissolve the fiber contained in the gou juice. The soymilk produced in this boiling step is cooled to a predetermined temperature, and then the two solids are mixed and solidified to form a tofu production method.

Further, the present invention relates to a stirrer for mixing soybean powder and water, and a pressure for boiling the kusu mixed with the stirrer while applying pressure so as to dissolve the fiber contained in the kusu. The tofu manufacturing device is composed of a boiling pot and a compression molding machine that cools the soymilk formed by boiling in the pressure boiling pot to a predetermined temperature and compression-molds the soymilk.

In the first embodiment of the present invention shown in FIG. 1 to FIG. 7, 1 removes soybean hulls to produce soybean powder 2 ground to 50 microns or less, preferably around 10 microns. In the soybean powder manufacturing process, this soybean powder manufacturing process 1 is, as shown in FIG. 3, a polishing process 3 for polishing the selected soybeans, a dehulling process 4 for peeling, and a water content of 5 to 6%. It is manufactured through a drying step 5 for drying, a pulverizing step 6 for pulverizing to 50 microns or less, preferably about 10 microns.

7, a soybean powder manufacturing process in which soybean powder 2 and water 8 etc. produced in the soybean powder producing process 1 are mixed with a stirrer 9 as shown in FIG. In manufacturing process 7, soy powder 2 was〗 kg of water 8 to about 6.8 liters, and 4.2 g of salt 26, 4.2 g of stabilizer 27, 5. Add foaming agent 28 to stirrer 9 and stir and mix for about 10 to 15 minutes.

11 is to supply the kure juice 10 produced in the kure juice production step 7 to a pressure boiling kettle 12 as shown in FIG. 5 in order to dissolve the fiber contained in the kure juice〗. 0 0 or more, preferably〗 20 · 5 to〗 0 minutes for about 5 minutes while stirring to boil into soy milk 13.Whose boiled in this boiling step 1 1 10 Filtration during transfer To remove impurities.
