Description

Technical Field

[0001] The utility model relates to the technical field of bean curd stick production, in particular to a soybean milk circulation system of a bean curd stick production line. Background Art

[0002] The existing yuba production process uses a long bean curd forming trough to transport soy milk. During the soy milk flowing from the front end to the end, the surface will gradually condense into a film. The film is lifted and cut at the end of the trough, and then formed into yuba by air drying. The soy milk that has not yet condensed is collected and then added back to the front end for recycling. Since the film on the top layer of the soy milk is taken away, the soy milk in the bean curd forming trough becomes less, and it is necessary to replenish soy milk at the end entrance of the bean curd forming trough. The existing soy milk replenishment method uses a pipeline for replenishment. The slurry delivery port of the pipeline is smaller than that of the flat bean curd forming trough, resulting in uneven soy milk flow rate in the bean curd forming trough and different thicknesses of the condensed bean curd film, which affects the preparation quality of the bean curd.

[0003] In order to solve the above problems, Chinese patent application number 202222432940.0 discloses a soy milk circulation system for a bean curd sheet production line, in which soy milk is first added to a pulp separation cylinder and then flows out from a homogenizing tube at the bottom. Since the pulp outlets are evenly arranged on the homogenizing tube, the supplemented soy milk enters the bean skin forming tank at a uniform speed everywhere. At this time, the soy milk in the bean skin forming tank coagulates at the same speed everywhere, and the finally generated bean curd sheet has uniform thickness and good consistency. However, the soy milk circulation system of the bean curd sheet production line has the following deficiencies: the temperature of the uncoagulated soy milk drops during reflux, and it fails to be heated to affect the formation of a thin film on the surface of the soy milk.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
