It is said that there are now freshly ground soybean milk machines and small machines for beating soybean milk, but it seems that tofu is made of soybean milk machines, and then something can be added by hand to make it. At present, I haven't heard of a machine that can directly make tofu brain. You can buy a machine for beating soybean milk and make it yourself. It's not funny. If you are a businessman, prepare to sell tofu brain. You can go to a store that sells agricultural equipment.
