The raw material with wet feather feathers as an example, the slaughter line down, use conveyor loading hydrolysis tank, normal temperature hydrolysis 30min, stamped seal, so that the bed temperature reaches 130 DEG C, to kill E.coli, break the keratin molecular chain, can reach 75% to improve product rate of digestion. To keep 15min working pressure is 0.25MPa, the steam water tank, after drying, cooling and crushed into powder, powder, yellow brown, become 80% protein content, moisture content is less than or equal to 10% of the hydrolysis of feather powder. Scope of application: broiler slaughter line feathers, fur animal bones, meat, viscera, casing and internal residue in transportation, residual dead poultry, livestock animal body, can cause a high temperature sterilization of feather meal, meat and bone meal, chicken powder, feather powder intestines. Cost analysis: for example: fresh meat to feather feather feather finished 14000 1000kg power consumption: 90kw / tons of coal consumption: 220 kg/ tons of artificial: 70 yuan / ton package 20 yuan / ton market price: 2400 yuan per ton - 2800
