Pressing method of beancurd

Abstract

The invention discloses a pressing method of beancurd, comprising a dehydration pressing process of removing moisture in beancurd jelly to press the beancurd jelly into beancurd. The method is characterized in that the dehydration pressing process is in a positive non-contact type. The positive non-contact type dehydration processing process comprises the following steps: firstly preparing a container with an opening, wherein the wall or the bottom of the container is provided with a filter structure for discharging moisture in the beancurd jelly; then placing the beancurd jelly in the open space of the container and shielding the filter structure; and finally sealing the opening of the container and ensuring the upper part of the beancurd jelly to form positive barometric pressure, and discharging moisture in the beancurd jelly through the filter structure. Compared with the prior art, by adopting a forming method through non-contact pressing of barometric pressure, the invention replaces the existing manual operation and the mechanical direct dehydration method through pressing, is characterized by remarkably reducing labor intensity, improving working efficiency, etc and simultaneously uses no pressure plate to directly contact the beancurd jelly, thus ensuring safety and health of food.

Description

technical field [0001] The invention relates to food processing technology, in particular to a method for pressing tofu. Background technique [0002] Tofu is a very delicious food, deeply loved by consumers. The pressing method of traditional bean curd generally comprises steps such as soaking beans, grinding, boiling, filtering, pointing (solidifying), dehydrating and forming. Also a lot of patents disclose the preparation method of various tofu in Chinese patent, as mung bean tofu, multi-layer tofu etc. The dehydration molding process of these tofu usually adopts the mechanical extrusion method. When the tofu flower needs to be pressed into tofu, a bottom plate and a square frame are prepared. The frame is placed on the bottom plate, and then gauze is spread in the frame , scoop the bean curd into the frame, and then press down the bean curd with a platen that is the same size as the frame, so that the water in the bean curd can flow out from the gauze and the gap betwe...

AI Technical Summary

Problems solved by technology

In this way, although the machine is used to replace human manual labor, the mechanical extrusion method is still used. The equipment has a complex structure and many parts, and a complex and huge mechanism needs to be installed above the container, which is not conducive to the miniaturization of the equipment. and home use

Moreover, the gland needs to be in direct contact with the tofu flower, that is, the tofu flower is dehydrated by contact extrusion, which is easy to cause pollution to the tofu
