TECHNICAL FIELD
[0001] The utility model relates to the technical field of edible animal oil grease processing, specifically is the frozen meat grinder with screening function. BACKGROUND
[0002] Edible animal oil is the grease extracted from animal fat tissue, which is used for human consumption, such as lard, beef tallow and mutton oil, etc.
[0003] Because many animal fat sources are frozen meat, which is convenient for storage, so in the processing of edible animal oil, the frozen meat grinder can crush the large pieces of frozen meat into smaller particles, so as to facilitate the subsequent processing procedures such as boiling.
[0004] The inventor found that the prior art has the following problems in the process of realizing the utility model: 1. At present, the frozen meat grinder is mostly manually pushed when feeding. First of all, frozen meat is a frozen product with small friction coefficient. When it comes into contact with the crushing assembly, there will be a problem of sliding. However, if it continues to rely on manual assistance to increase the contact area between it and the crushing assembly, it will not only increase the complexity of the work, but also pose a safety hazard. 2. And the current crushing equipment is to directly crush the raw materials without providing the function of screening, which will produce particles of different sizes. Because the size difference of the particles is too large, the small particles of frozen meat may release fat quickly, while the large particles of frozen meat may need longer time to fully boil, which will lead to inconsistent oil release time and difficult to guarantee the quality of the final product.
