Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic tofu skin and bean curd stick technology, specifically to automatic tofu skin and bean curd stick equipment. Background Technology
[0002] Tofu skin and dried bean curd sticks are made from a layer of oil that forms on the surface of heated soy milk. Traditionally, making tofu skin and dried bean curd sticks requires repeatedly skimming and drying the oil film from the surface of the soy milk by hand, which is not only wasteful of labor costs but also difficult to control in terms of hygiene. Later, automated tofu skin and dried bean curd stick equipment emerged. The soy milk is placed in a rectangular container, heated from the bottom, and blown on top to quickly coagulate it into a film. Then, the oil film is pulled up from one end by a conveyor belt, and hot air is blown on top of the belt to dry the tofu skin. This cycle is repeated, achieving automatic skin formation and drying.
[0003] The existing automatic bean curd skin and tofu skin equipment does not allow for height adjustment of the conveyor belt, which causes obstacles during pot washing and makes it inconvenient to use. In addition, the cold air pipes for blowing soy milk in the existing automatic bean curd skin and tofu skin equipment are positioned too low, and dozens of air pipes must be removed after each pot washing, resulting in a long pot washing time and poor practicality.
