The steam pipe connects to the bottom of each cooking tank 1 for steam input, and the exhaust pipe connects to the top of each cooking tank 1. The steam pipe supplies steam into each cooking tank 1 to cook the raw soybean milk, and the exhaust pipe discharges steam, creating a steam circulation system to heat the raw soybean milk. A safety valve 11 is also installed at the top of each cooking tank 1 for venting steam. When the steam pressure in the cooking tank 1 exceeds the opening pressure set by the safety valve 11, the safety valve 11 opens to release steam.
