Description

Technical Field

[0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a soybean protein gel dehydration mechanism. Background Art

[0002] Dried tofu is a processed tofu product. It is salty, fragrant, and refreshing, firm yet chewy, and it lasts for a long time. Dried tofu is one of the best foods to go with wine or rice, and is also convenient to carry and eat while traveling. Currently, the production of dried tofu has a low level of automation, especially in the dehydration of the soy protein gel. The traditional process involves manually preparing a flat plate, placing a correspondingly sized frame on top, and placing a piece of cloth inside the frame. Workers scoop the soy protein gel (tofu pudding) into the center of the cloth and evenly smooth or sprinkle it onto the cloth (a process also known as "breaking the brain"). The cloth is then evenly wrapped around the soy protein gel (tofu pudding), and this process is repeated, typically about 30 times, before the frame is removed. Pressure is applied to the surface of the soy protein gel using pneumatic or hydraulic equipment or a heavy object, separating water and small particles such as whey protein from the gel. After the pressing is complete, the flat plate is removed one by one from top to bottom, and the cloth is torn open to remove the finished soy protein gel.

[0003] The above mainly describes the traditional process for producing low-moisture soy protein gel. Other production methods exist on the market, but they are less popular. For example, the back-and-forth folding tofu machine cannot produce thicker tofu due to structural reasons. Moreover, the crushing process requires very fine pieces, which goes against the customer's demand for a good taste. When thicker tofu is required, traditional tofu presses are still required.
