The box body 1 is a steamer main body, and a heating plate and a rack are installed inside, an inlet pipe is arranged at the side, a drain pipe is arranged at the bottom, and a valve is respectively installed on the inlet pipe and the drain pipe. The water is heated by a heating plate to generate steam. The steam processing apparatus includes a fin-type condensing plate 3 mounted on the top of the casing 1, and a cooling fan 8 mounted on the lower side of the fin-shaped condensing plate 3. An exhaust port is opened at the side of the casing 1, and the exhaust port is connected to the inlet of the condensing plate 3 through the exhaust pipe 2. A condensate water pipe 4 is connected at an outlet of the condensing plate 3, and an outlet of the condensate water pipe 4 is connected to an inlet at the top of the pressure-reducing water storage tank 5. A check valve 6 is connected under the pressure-reducing water storage tank 5, and a water return pipe is connected to the bottom of the one-way valve 7. The return pipe 7 extends into the casing 1. The check valve 6 ensures that the condensed water in the pressure-reducing water storage tank 5 flows into the tank 1, and prevents the steam in the tank 1 from flowing from the return water pipe 7 into the pressure-reducing water storage tank 5.

Among the gases emitted by the water tank 1, the steam accounts for the majority, and also contains other gases that are volatilized by heat, which contain food odors or other volatile substances. Via the condenser 3, the steam is condensed into condensed water which is discharged or recovered from the pressure-reducing water storage tank 5, and the other gases are required to be discharged.
