A rotating shaft 11 is rotatably installed on the bottom wall of the cover plate 8, and a second motor 12 connected to the rotating shaft 11 is fixedly installed on the upper end surface of the cover plate 8. Two stirring shafts 14 are rotatably installed on the outer wall of the rotating shaft 11 through two connecting plates 13. The outer walls of the two stirring shafts 14 are connected to the gear ring 10 through a rotating mechanism. The rotating mechanism includes a gear 15 fixedly installed on the outer wall of the stirring shaft 14, and the gear 15 is engaged with the gear ring 10.

Connecting rods 18 are fixedly installed at both ends of the two connecting plates 13, and the ends of the two connecting rods 18 on the same side are commonly fixedly connected with a scraper 19. Two refrigerators 20 are fixedly installed on the outer wall of the kettle body 1. Both refrigerators 20 are semiconductor refrigerators. The semiconductor refrigerator uses semiconductor cooling sheets as main components. Semiconductor cooling sheets are also called thermoelectric cooling sheets. The principle is the Peltier effect. It can both cool and heat. The cooling or heating is determined on the same cooling sheet by changing the polarity of the DC current.
[0025] When the utility model is used, the material is poured into the kettle body 1, and then the first motor 4 drives the screw rod 3 to rotate, and the screw rod 3 drives the movable sleeve 6 to move by cooperating with the limit rod 5, and the movable sleeve 6 drives the cover plate 8 to descend through the fixed rod 7, thereby the cover plate 8 can cover the upper end surface of the kettle body 1, and the cover plate 8 can also drive the multiple stirring rods 17 to descend into the kettle body 1 while descending.
