The circulation pump 5 is fixedly installed on the top of the outer casing 1. The water outlet of the circulation pump 5 is connected with a delivery pipe 51, and the delivery pipe 51 is hermetically and rotatably installed inside the hollow shaft one 3. A plurality of upper through holes 301, injection holes 303 and a plurality of lower through holes 302 are sequentially formed in the hollow shaft one 3 from top to bottom. And a plurality of injection holes 303 are all located inside the inner casing 2.

[0047] Working principle:

[0048] In practical applications, when pasteurization treatment of milk is required, first, the power supply is connected and the water inlet of the circulation pump 5 is connected to the water source. Then, the water is injected into the hollow shaft one 3 through the delivery pipe 51 by the circulation pump 5. The lifting plate 42 is adjusted by the electric cylinder 43, and with the cooperation of the fixed rod 41, a plurality of through holes 401 on the hollow shaft two 4 can be adjusted to a state communicating with the hollow rod 31. Under the action of the plurality of upper through holes 301, the plurality of lower through holes 302, and the plurality of through holes 401, the water can fill the space between the inner housing 2 and the outer housing 1, the hollow shaft one 3, the hollow shaft two 4, and the hollow rod 31. Then, the water in the inner housing 2 is heated by the temperature control module 6 and heated to the preset sterilization temperature of the milk. Then, the milk to be treated is introduced into the inner housing 2 through the feed pipe 21, so that the milk in the inner housing 2 can be heated and reach the temperature range required for pasteurization.

[0049] During the heating process, the motor 34 starts to work, and its output shaft drives the driving gear 35 to rotate. Then, through the meshing action of the driving gear 51 and the gear 52, the hollow shaft one 3 drives the plurality of hollow rods 31 fixedly installed thereon and the scraping strip 32 to rotate together. The scraping strip 32 contacts the inner side wall of the inner housing 2 and can continuously scrape the inner wall as it rotates. At the same time, the hollow rod 31 continuously stirs the milk, so as to ensure that the milk is evenly heated.

[0050] After sterilization, the milk is discharged through the discharge pipe 21. Then, the hollow shaft two 4 is adjusted by the electric cylinder 43, and the plurality of through holes 401 coincide with the plurality of injection holes 303, so as to achieve the effect of jetting water flow to wash the inner wall of the inner housing 2. At the same time, with the continuous rotation of the hollow shaft one 3, the inner wall of the inner housing 2 can also be cleaned under the action of the plurality of scraping strips 32.
