Description

Technical Field

[0001] The utility model belongs to the field of experimental mouse feed granulator equipment, in particular to a device for improving the gelatinization degree of starch in experimental mouse feed. Background Art

[0002] Laboratory mice are one of the commonly used experimental animals in scientific research. They are small in size, reproduce quickly, have low feeding costs, and have similar physiological characteristics to humans. Therefore, they are widely used in biology, medicine, pharmacology, genetics and other fields. In the field of life science research, laboratory animals are recognized as indispensable living precision instruments. To ensure that laboratory animals have good sensitivity, accuracy, and repeatability in animal experiments and meet quality requirements, standardization is necessary. The quality of laboratory animal feed directly affects the quality of the animals. Feed hardness is one of the important indicators of feed sensory quality.

[0003] The teeth of laboratory mice do not experience the process of shedding and replacement, and they maintain continuous growth. Laboratory mice are born with the characteristic of gnawing, and their feed consumption is quite large. This is one of the most direct factors affecting the production cost of laboratory mice. There are many factors that affect the hardness of feed, such as the particle size of the raw materials, the starch content in the raw materials, the uniformity of feed mixing, the moisture content of the powder, etc., and the external ambient temperature will also have a certain impact on it. In the high temperature season in summer, the hardness of the finished feed usually decreases. Through research, it is found that this is because the temperature is too high, causing the water in the feed to evaporate faster than in other seasons, thereby reducing the hardness. In the production process, since the material temperature and moisture are not easy to control freely, the feed hardness is affected by related factors and cannot be maintained stable, resulting in large fluctuations in the hardness data of the finished feed.
