Problems solved by technology

Although the above technical solutions can turn chicken feathers and chicken blood into treasures, the treatment process is more complicated and the cost is higher, while the rest of the leftovers such as glandular stomach and claw skin cannot be processed, so they can only be discarded and allowed to pollute the environment

Embodiment 1

[0029] First put 2 tons of washed fresh chicken feathers, 0.1 tons of fresh chicken blood, 0.1 tons of fresh glandular stomach, and 0.1 tons of fresh claw skin into a pressure stirring tank and mix evenly. When stirring, the temperature in the tank is 180 °C and the pressure is 0.38 MPa. The temperature in the tank is raised to 450°C for high-temperature cooking to hydrolyze the input materials. The high-temperature hydrolysis time is 3 hours. Stirring is performed during high-temperature hydrolysis, and then the high-temperature hydrolyzate in the pressure stirring tank is pumped into the tube bundle dryer for drying to form The semi-finished feather blood powder is dried at 170°C, the dryer pressure is 0.4 MPa, and the drying time is 40 minutes. Finally, the semi-finished feather blood powder is passed through a 4-mesh filter for inspection. The water content is 11%, crude protein reached 76.18%, measured and weighed 50 kg / bag, stored in storage after bagged.

Embodiment 2

[0031] First put 2.5 tons of washed fresh chicken feathers, 0.3 tons of fresh chicken blood, 0.2 tons of fresh glandular stomach, and 0.15 tons of fresh claw skin into a pressure stirring tank and mix evenly. When stirring, the temperature in the tank is 160 °C and the pressure is 0.38 MPa. The temperature in the tank is raised to 460°C for high-temperature cooking to hydrolyze the input materials. The high-temperature hydrolysis time is 3 hours. Stirring is carried out during high-temperature hydrolysis, and then the high-temperature hydrolyzate in the pressure stirring tank is pumped into the tube bundle dryer for drying to form The semi-finished feather blood powder is dried at 180°C, the pressure of the dryer is 0.4 MPa, and the drying time is 40 minutes. Finally, the semi-finished feather blood powder is passed through a 4-mesh filter for inspection. The water content is 10.82%, crude protein reached 76.45%, measured and weighed 50 kg / bag, bagged and stored in storage.

Embodiment 3

[0033] First put 3 tons of washed fresh chicken feathers, 0.5 tons of fresh chicken blood, 0.3 tons of fresh glandular stomach, and 0.2 tons of fresh claw skin into a pressure stirring tank and mix evenly. When stirring, the temperature in the tank is 200 °C and the pressure is 0.4 MPa. The temperature in the tank is raised to 480°C for high-temperature cooking to hydrolyze the input materials. The high-temperature hydrolysis time is 3 hours. Stirring is performed during high-temperature hydrolysis, and then the high-temperature hydrolyzate in the pressure stirring tank is pumped into the tube bundle dryer for drying to form The semi-finished feather blood powder is dried at 200°C, the dryer pressure is 0.45 MPa, and the drying time is 40 minutes. Finally, the semi-finished feather blood powder is passed through a 4-mesh filter for inspection. The water content is 9.74%, crude protein reached 77.02%, measured and weighed 50 kg / bag, put into storage after bagging.

Abstract

The feather-blood powder with high amino acid content is prepared with fresh chicken feather, fresh chicken blood, fresh claw skin and fresh glandular stomach in certain weight proportion, and through washing, mixing, high temperature steaming to hydrolyze the material mixture, stoving, sieving, inspection and packing. The simple and low-cost preparation process changes the leftover of meat chicken production into the feather-blood powder with high amino acid content and avoids environmental pollution effectively.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to a high amino acid feather blood meal made from poultry leftovers and a preparation method thereof. Background technique [0002] At present, in the process of processing and slaughtering broiler chickens, there are always leftovers such as chicken feathers, chicken blood, glandular stomach, claw skin, etc., except for a few that still have use value, most of them will be abandoned. In addition to polluting the environment, it also wastes recyclables. utilize resource. For this reason people have done the research that utilizes chicken feather to make fertilizer and extract medicine from chicken blood, for example publication number is the Chinese invention patent application " chicken feather produces cystine and additive compound amino acid method " of CN1168884, and this method first chicken feather Carry out hydrolysis, neutralization, and then refine twice,...
