[0023] Working principle: when the technical solution is used, first of all, the support rod 3 is placed in the required position, then the extension of the electric push rod 8 can drive the upper tube body 15 and the lower tube body 10 to slide downward or upward in the kettle body 1 through the circular block 12, so that the feed inlet 17 can correspond to or be away from the feed pipe 4 and the steam input port 18 can correspond to or be away from the steam input pipe 6, the feed pipe 4 can introduce raw materials into the upper tube body 15 and the lower tube body 10 through the feed inlet 17, and the steam input pipe 6 can introduce steam through the steam input port 18, so that the liquid can be intermittently fed, thereby the liquid can be effectively and uniformly flashed, and the flashing efficiency is improved. When the liquid material enters the kettle body 1 and the lower tube body 10, high-temperature and high-pressure steam is input through the steam input pipe 6, so that the pressure in the kettle rapidly rises. At this time, the saturated steam pressure of the liquid material also rises, but the saturated steam pressure of the liquid material is still low because the temperature of the liquid material is low. Therefore, when the pressure in the tube reaches a certain value, the saturated steam pressure of the liquid material will be lower than the pressure in the kettle body 1.
