In terms of raw materials, we take feather for an example, putting the wet chicken feather which got from slaughtering line into hydrolysis feather powder with belt conveyer, then not contact air with cover after hydrolyze 30min under room temperature, the purpose for making temperate of batch layer reaching 130℃, to kill bacillus coli, break down cornifin molecular chain, which help to reach 75% of digestibility of products. Lasting the condition of 45min that the working pressure achieves 0.25mpa, discharging steam in cylinder, breaking them up after cooling, that is, change to a sort of tawny powder, with content of protein achieving to 80%. It is fit for feather which obtained from slaughtering line, skeleton, internal organs dogmeat intestine and casing and internal remains of fur animals, animal carcase of dead livestock on the course of transportation, which can all be make into feather powder, meat and bone meal, chicken meal, Intestinal feather powder and so on which have functions of sterilizing under high temperature.
