Description

Technical Field

[0001] The utility model relates to the technical field of colloid mills, and more specifically, to a colloid mill with a cooling structure. Background Art

[0002] A colloid mill uses an electric motor to drive the rotating teeth and matching fixed teeth to rotate relative to each other at high speed. One rotating gear rotates at high speed while the other is stationary. The material being processed, through its own weight or external pressure, generates a downward spiral impact force. As it passes through the gap between the fixed and rotating teeth, it is subjected to strong shear forces, friction, high-frequency vibration, high-speed vortex, and other physical effects. This effectively emulsifies, disperses, homogenizes, and pulverizes the material, achieving ultra-fine grinding and emulsification. During the pet food processing process, the rotating and fixed teeth generate high temperatures when processing the material, which can denature the processed material.

[0003] After searching, the utility model patent with announcement number CN214553993U discloses a high-efficiency colloid mill with a cooling system, including a colloid mill main body, a processing cylinder of the colloid mill main body is provided with a connected discharge pipe, and the discharge pipe is provided with a valve, a water storage hopper is embedded in the outer wall of the processing cylinder of the colloid mill main body, and one end of the water cooling inlet pipe is inserted into the water storage hopper, and the other end of the water cooling inlet pipe is connected to the water inlet end of the water pump, and the water outlet end of the water pump is connected to the water cooling outlet pipe. The water-cooling outlet pipe and the water-cooling inlet pipe are both set to a "7" type structure; the high-efficiency colloid mill with a cooling system is provided with a water storage hopper, the water in the water storage hopper can absorb the heat conducted from the processing cylinder of the colloid mill main body, making it easier for the heat to be dissipated outside the colloid mill main body, and the device is provided with a water pump, which can complete an external circulation of the water in the water storage hopper through the water-cooling inlet pipe and the water-cooling outlet pipe, so that the heat dissipation efficiency of the colloid mill main body is further improved, meeting the working requirements of efficient cooling of the colloid mill main body.

[0004] However, the above patent has the following shortcomings: the top of the water storage hopper is not closed, and the water cooling inlet and outlet pipes are prone to splashing when cooling the colloid mill body, affecting the cooling quality; and the cooling effect of the cooling water by relying on the fan is not good. To address this problem, we propose a colloid mill with a cooling structure. Utility Model Content
