A production process of bean curd skin comprises the following steps:

specifically, the degree of grinding is controlled, and the particles can be twisted into small particles by fingers.

S4: filtering the soybean milk, washing the ground raw materials with hot water, uniformly stirring, putting the raw materials into a separator with a 80-90 mesh filter screen, and separating the bean dregs from the soybean milk;

specifically, the soybean milk can be filtered by adopting bean curd filter cloth, the soybean milk is poured into the filter cloth, the filter cloth is shaken to filter the soybean milk, and the soybean milk can be drained after three times of filtering.

specifically, in the film forming process of the bean curd skin, the temperature of the soybean milk is one of the important factors influencing the quality and the yield of the bean curd skin, the soybean milk is kept at a proper temperature to provide enough heat for the denaturation of the soybean protein, namely the polymerization energy required by the polymerization of the soybean protein, so that the gel structure of the protein and the quality and the yield of the bean curd skin are influenced, and the proper soybean milk temperature is controlled to be about 85 ℃.

Furthermore, the yield of the skin of soya-bean milk is increasing with the increase of the depth of the soya-bean milk, which is mainly due to the fact that the proportion of the soya-bean milk which can not form the film finally is reduced, however, when the depth of the soya-bean milk exceeds 5cm, although the yield is still increasing, the range is greatly reduced, the film forming speed is also reduced, and in order to ensure the yield and the quality of the skin of soya-bean milk at the same time, the depth of the soya-bean milk in the forming groove should be controlled to be about 5 cm.

The specific drying is to remove excessive moisture in the bean curd sheets, and is an important link in the bean curd sheet skinning process, and the traditional drying method is long in time and poor in sanitary condition, so that an automatic and continuous drying mode is adopted to ensure the quality of the bean curd sheet products.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
