AI Technical Summary

Technical Problem

In animal protein processing, heat is generated between grinding blocks during prolonged grinding, leading to an increase in temperature and affecting the emulsification of salt-soluble proteins.

Method used

A colloid mill suitable for animal protein production was designed, comprising a cooling water chamber and a cooling water delivery assembly. The cooling water in the cooling water chamber cools the stationary grinding plate, and heat dissipation vents are provided on the rotating grinding block to dissipate heat and ensure that the grinding block remains at a low temperature.

Benefits of technology

Effectively controlling the grinding block temperature prevents the denaturation of salt-soluble proteins, maintains emulsification, and ensures the quality and taste of animal protein products.

Abstract

The utility model relates to the technical field of colloid mills, and discloses a colloid mill suitable for animal protein production, which comprises a shell, a fixed grinding plate I mounted on the inner side of the upper part of the shell, a feeding pipe mounted on the eccentric side of the fixed grinding plate I, a cylindrical fixed grinding plate II mounted on the inner wall of the shell and positioned on the lower side of the fixed grinding plate, and a rotary grinding block rotatably mounted in the shell, a motor connected with the rotary grinding block is mounted at the bottom of the shell; a slurry outlet groove is mounted between the lower part of the shell and the lower part of the fixed grinding plate II in a penetrating manner; a cooling water cavity is formed in the second fixed grinding plate, and a cooling water conveying assembly communicating with the cooling water cavity is installed on the shell. Compared with the prior art, the cooling water cavity is formed in the second fixed grinding plate, cooling water is continuously conveyed into the cooling water cavity through the cooling water conveying assembly, the temperature of the second fixed grinding plate is reduced, the second fixed grinding plate makes contact with the first fixed grinding plate, the first fixed grinding plate is cooled, the multiple sets of first heat dissipation openings are formed in the side wall of the rotary grinding block, and the cooling effect is good. And good heat dissipation can be achieved.
