Rendering Hydrolyzer Model Is SRSJ1228-7 Feather Meal Processing Equipment

Many countries have poultry farming, which generates a lot of waste to be disposed of. Most of them are feathers with protein content as high as 85-90%. Feathers in their natural state cannot be digested, but feather meal can be obtained through various processing. Feather meal as a kind of animal protein feed has been applied to animal feeding. Therefore, processing feathers and applying feather meal provides a relatively cheap protein feed material to solve the growing problem in many parts of the world, including China.

The demand for animal protein products is very necessary. Feathers are mainly keratin and have a structure. The cross-chains between its side chains strengthen this structure. These chains are connected by hydrogen bonds to form a cylinder, and then form a cord-like structure. The disulfide bond formed by cysteine ​​between these cylinders stabilizes this structure. It is precisely because of the existence of this structure that keratin It can resist the digestion of digestive enzymes in the intestine. In order to make digestive enzymes work on keratin, it is necessary to destroy its chemical structure through hydrolysis. At present, several methods have been used to open the hydrogen bonds between keratin molecular chains. Usually, steam and a certain pressure are used to hydrolyze feathers to increase the availability of nutrients, and heat denaturation is considered the most economical method. Strong alkali treatment and enzymatic methods are also used, but the results are limited. The processing methods of each processing method may be different, but the overall processing conditions are similar. First, the feathers with a moisture content of 60-70% are baked at a certain temperature and pressure for a certain period of time, and then dried at a certain temperature.
