As a bean curd filter screen, the standard filter screen for filtering soybean milk is 100 mesh or 120 mesh, and it is also useful for 200 meshes. Because it is to make tender tofu, it is suggested to choose a large mesh, such as a 200 mesh filter, because the filtered soybean milk is smoother and the tofu will be more tender.

Tender bean curd is generally a guide bean curd. When filtering soybean milk, traditional manual workshops mainly use traditional filtration methods, such as hanging bag filtration and extrusion filtration. This method does not need any mechanical equipment and has low cost, but it is labor intensive, takes a long time to filter, and the content of residual protein in bean dregs is also high.

In larger factories, horizontal centrifugal screen filtration, flat screen filtration and circular screen filtration are mainly used. Horizontal centrifugal screen filtration is the most widely used filtration separation method at present.
