Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to an extrusion type tofu dehydration device. Background Art

[0002] Tofu contains many trace elements necessary for the human body and is rich in high-quality protein. It is known as "plant meat" and is a nutritious food with a long history. The traditional tofu making technique has been selected into the fourth batch of China's national intangible cultural heritage representative project list.

[0003] The basic process of traditional tofu production is that soybeans are cleaned, soaked, and ground, and then filtered to remove bean dregs, and then boiled and brined to solidify, and finally squeezed and dehydrated to form. Extrusion is required for dehydration. The traditional method is to use heavy objects such as stones for extrusion. Modern production workshops use equipment such as cylinders or electric cylinders for extrusion. Taking the electric cylinder as an example, the gel-like soybean protein and yellow pulp water that have been ground are poured into a container together. Gauze is padded in the container. After the gauze is folded to wrap the soybean protein gel, the electric cylinder pushes the pressing plate down, and the top of the gauze bag is stressed and gradually flattened, and the yellow pulp water in the soybean protein gel is squeezed out. There are some functional deficiencies in actual use, and there is room for improvement. For example, most of the containers currently used to hold soybean protein are fixed. After extrusion and drainage, when the tofu needs to be taken out, it can only be taken out by pulling the gauze bag. When the gauze bag is pulled upward, the corners of the tofu are subjected to large force and the center is subjected to small force, which is prone to cracking, corner breakage and other problems, affecting the appearance of the tofu, and it does not have the function of being easy to demold and take out.

[0004] Now, a novel extrusion type tofu dehydration device is proposed to solve the above problems. Utility Model Content
