TECHNICAL FIELD

[0002] Microbial fermentation granular feed is a kind of biological feed or feed raw material with rich nutrition, good palatability and high viable bacteria content, which is formed by using the metabolic activities of microorganisms (such as bacteria, yeast, mold, etc.) to degrade polysaccharides, proteins and fats in raw materials into small molecules such as organic acids and soluble polypeptides under specific fermentation conditions. These microorganisms not only degrade complex organic matter in raw materials, but also synthesize a variety of beneficial substances such as vitamins, enzymes and growth promoting factors during the fermentation process.
[0003] However, after the fermentation production is completed, the temperature of the feed is often high after being cut and extruded from the extruder. Direct packaging at this time will cause the feed to be soft due to high temperature, resulting in the formation of clumps due to extrusion. Therefore, personnel often need to cool the feed particles through a device. The existing feed cooling method relies on air cooling and freeze drying cooling. Air cooling uses the method of accelerating air flow to cool down. Although it can play a role, the specific heat capacity of air is low, and the cooling effect is limited.
