By designing the stirring mechanism 9, the material can be uniformly stirred and cooled.

[0022] Working principle: During use, the material to be cooled is fed into the tank 1 through the feed port 73 and discharged through the discharge port 74. Simultaneously, the water supply pipe 82 delivers cold water to the fixed base 10 and the rotating base 11. The cold water is then atomized and sprayed through the atomizing nozzle 81. The material is cooled by contact with the cold water. During spraying, the drive motor 83 operates simultaneously. The output of the drive motor 83 drives the rotating rod 84 to rotate, which in turn drives the first bevel gear 85 to rotate. The first bevel gear 85 drives the second bevel gear 86 to rotate, which in turn drives the rotating shaft 87 to rotate along the support base 88. The rotating shaft 87 then drives the third bevel gear 89 to rotate, which in turn drives the fourth bevel gear 891 to rotate. Wheel 891 drives the rotating seat 11 to rotate, which in turn drives the atomizing nozzle 81 to rotate and spray, improving the uniformity of contact between the atomized cold water and the material, and enhancing the cooling effect of the material. Furthermore, when feeding through the feeding port 73, the rotating motor 75 is simultaneously activated. The output of the rotating motor 75 drives the gear ring 76 to rotate, which in turn drives the gear ring 77 to rotate. The gear ring 77 then drives the feeding port 73 to rotate, which in turn drives the discharge port 74 to rotate. The material can then be discharged through the discharge port 74, causing it to be dispersed and sprayed out under the influence of centrifugal force, allowing for uniform feeding into the tank 1, further improving the uniformity of contact between the atomized cold water and the material, and further enhancing the cooling effect.

[0023] After initial cooling, the material falls to the bottom of the tank 1. The semiconductor cooling chip 4 can cool the inside of the tank 1, thus achieving secondary cooling of the material and effectively improving the cooling efficiency. When the connecting rod 78 rotates, it also drives the stirring rod 91 to rotate, which can evenly stir the material and improve the cooling efficiency. When the connecting rod 78 rotates, it also drives the connecting rod 92, the sliding rod 93 and the scraper 94 to rotate. The scraper 94 can scrape off the material adhering to the inner wall of the tank 1, avoiding material residue and waste. The spring 97 inside the connecting rod 92 is in a compressed state, which will give the slider 95 an outward push. At the same time, under the influence of the centrifugal force of rotation, the scraper 94 can be pressed tightly against the inner wall of the tank 1, which can improve the cleaning effect of the residual material on the inner wall of the tank 1.
