Technical Field

[0001] The utility model relates to the technical field of pet food processing, in particular to a primary screening mechanism for pet food raw materials after they are crushed. Background Art

[0002] In the current field of pet food processing technology, pet food is a kind of food for pets, which is made of chicken breast, corn starch, fish, propylene glycol, sorbitol, MSG, red yeast rice flour, soy protein isolate potassium sorbate, garlic powder, wheat flour, etc. After the pet food is crushed, it needs to be screened using a primary screening mechanism.

[0003] In the prior art, the crushed raw materials are often preliminarily screened by the vibration of a cylindrical screen installed in a frame, so that the raw materials and impurities can be separated. However, the preliminarily screening method using only one cylindrical screen can only separate impurities larger than the raw materials, while impurities smaller than the raw materials are still mixed in the crushed raw materials, resulting in poor preliminarily screening effect. Furthermore, the impurities after the preliminarily screening are still retained in the cylindrical screen, and it is inconvenient to remove them. Therefore, it is necessary to propose a preliminarily screening mechanism for crushed pet food raw materials to solve the above-mentioned problems. Utility Model Content
