[0002] Tofu contains many essential trace elements and high-quality protein, earning it the nickname "plant-based meat." Its digestibility is over 95%. Tofu production involves two steps: pulping, which involves turning soybeans into soy milk; and coagulation, which involves the use of heat and a coagulant to solidify the soy milk into a water-rich gel, the soy milk itself.

[0003] The original process flow of pressing tofu by the weight of turnover baskets is that first, non-woven fabric is manually spread flat in the turnover box, and the area of ​​the non-woven fabric is 1 times that of the turnover box. The required tofu pudding is filled in the turnover box (the source of tofu pudding can be in various forms, including small barrel slurry coagulation machine, large barrel slurry coagulation, slurry flushing, etc.), and then the excess part of the non-woven fabric is folded on top of the tofu pudding to confirm that no tofu pudding is exposed. Then, a new turnover box is placed on top of it, and the above steps are repeated to stack the turnover boxes to the appropriate height to form self-pressure. After a period of self-pressure, manual pouring is required. Pour-over pressing is to manually pour the top layer to the bottom and the bottom layer to the top to achieve the purpose of uniform pressure on all tofu. However, this process has a low degree of automation and is time-consuming and labor-intensive.
