Preparation method of bean curd skin

Abstract

The present invention discloses a preparation method of bean curd skin. The preparation method comprises the following steps: (1) selecting raw materials; (2) soaking soya beans; (3) grinding pulp; (4) performing centrifugal filtration; (5) boiling pulp; (6) discharging boiled pulp: putting the boiled pulp into a skin-forming groove, controlling the temperature of the boiled pulp at 95-98 DEG C and the solid content of the boiled pulp at 10-11%, running a rear fan when 1/3 of the skin-forming groove is filled with the boiled pulp, and opening all steam valves to heat, with the steam pressure not more than 0.2 MPa and the heating temperature controlled at 95-97 DEG C; (7) forming skin: pulling the bean curd skin to a conveyor belt when the surface of the boiled pulp begins to form skin andsmall wrinkles appear in the skin, opening the pulp-returning pump when the formed skin is uneven and the skin forming is slow, controlling the speed of pulp returning through the valves, and using the recovered soya bean milk to produce other products; (8) drying the bean curd skin; and (9) packing products. The prepared bean curd skin is delicate, uniform in thickness and not easy to break. In addition, the preparation method improves the utilization rate and production efficiency of the soya beans, and prolongs the shelf life of the bean curd skin by spraying table salt water and spirit.

Description

technical field [0001] The invention relates to the technical field of bean products processing, more specifically, it relates to a preparation method of bean curd skin. Background technique [0002] Tofu skin is a kind of yuba in a broad sense.

Long-term consumption of the elderly can prolong life. Especially for pregnant women during the postpartum period, it can not only restore their health quickly, but also increase milk supply. Tofu skin also has the advantages of easy digestion and quick absorption. It is a good food suitable for women, children, old and weak. [0003] my country's soybean products are very traditional in terms of technology and equipment, and even some enterprises have a certain scale of workshop-style and manual production. The bean curd skins purchased on the market are basically all handma...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the manual production method is adopted, and the speed and quality of the skin are difficult to control. The quality of the tofu skin produced is uneven, the thickness is different, it is easy to break, the processing efficiency is low, and the shelf life is short.
