The upper surface of the kettle cover 5 is fixedly connected with a pressure gauge 4. The sensing head of the pressure gauge 4 extends into the kettle body 1, which is convenient for observing the air pressure in the kettle body 1. The kettle cover 5 is fixedly connected to the upper flange 19 by a nut, so that the kettle cover 5 seals the kettle body 1 to prevent liquid from splashing out during stirring. The inner surface of the kettle body 1 is fixedly connected with an inner tank 21, and a discharge port 10 is provided on the lower surface of the kettle body 1. A throttling control device is fixedly connected to the lower surface of the kettle body 1.
