Description

Technical Field

[0001] The utility model belongs to the field of experimental animal feed screening equipment, in particular to a device for ensuring the uniformity of experimental animal feed powder. Background Art

[0002] Laboratory animals are animals used for experimental purposes in scientific research, usually in the fields of disease research, drug testing, biological research, etc. The purpose of using these animals in experiments is to obtain important information related to human health and disease, as well as to develop new treatments and drugs. The quality of laboratory animal feed directly affects the nutritional supplementation of animals, and is the basis for ensuring the healthy growth and reproduction of laboratory animals, the smooth progress of animal experiments, and the accuracy and repeatability of experimental results;

[0003] Crushing is the first process in feed production. It uses physical effects such as friction, collision and shear force to change the structure and properties of starch particles. Friction crushing treatment will reduce the relative crystallinity of natural starch and form a loose and porous structure on the surface of starch particles, thereby changing the physical and chemical properties of starch such as water absorption and solubility, and ultimately affecting the digestibility of starch. The crushing particle size of different feed raw materials varies. Too fine or too coarse crushing particle size may affect the digestion and absorption of nutrients in the feed by experimental animals.

[0004] In the existing production equipment, the feed powder particle size is completely affected by the grinder equipment and the grinding method, but there are still differences in the grinding particle size of the processed cereal raw materials and other raw materials. In addition, due to the different bulk densities of various feed raw materials, powder grading may occur during the next feed processing step. The difference in grinding particle size will increase the powder grading phenomenon, thereby affecting the quality of the final product.
