What are the categories of puffed corn?

According to the bulk density of the final product (after drying and cooling, 2mm sieve plate crushing), the expanded corn can be divided into three types: nTH China Feed Industry Information Network - based on feed, serving animal husbandry

1. First-class expansion product. The bulk density is >0.5kg/l, generally low temperature puffing, about 80~120oC, the finished product has higher moisture content, and the gelatinization degree can be 60~80%. It can be used in piglets after milking, and can also be used in multi-dimensional and enzyme preparation coating process. nTH China Feed Industry Information Network - based on feed, serving animal husbandry

2, second-class expansion products. The bulk density is 0.3-0.5 kg/l, the temperature is about 100-160oC, the finished product moisture is 6-10%, and the gelatinization degree can be more than 90%. It is used for special animal feed such as suckling pig, scorpion, fox and leeches, and aquatic feed. nTH China Feed Industry Information Network - based on feed, serving animal husbandry

3. Third-grade expansion products. The bulk density is 0.1-0.3 kg/l, the temperature is 140-170oC and higher, and the finished product moisture is 4～8%. It can be completely gelatinized. It is generally dry-expanded, used in the carrier of composite phospholipid powder, and foundry industry and coating industry. nTH China Feed Industry Information Network - based on feed, serving animal husbandry

It should be pointed out that the degree of corn expansion required by special fur animals is higher than that required for suckling pigs, and most of the bulk density is around 0.3. Therefore, the requirements for puffed corn in the northern region are higher than those in the south. nTH China Feed Industry Information Network - based on feed, serving animal husbandry

At present, theoretically, the bulk density of 0.4~0.5 can be used for suckling pigs, but users tend to use the requirements of fox mites to select puffed corn. (Internet) nTH China Feed Industry Information Network - based on feed, serving animal husbandry
