Method for producing amino acid fertilizer from dead animals

Abstract

The invention discloses a method for producing an amino acid fertilizer by using animals died of illness. The method comprises the following steps: pre-treating dead bodies of animals died of illnessto obtain a raw material A; mixing two or more of rice bran, bran, corn flour, straw powder and crushed dry branches and fallen leaves to obtain a mixture B, adding a microbial starter and water, andperforming pre-fermentation to obtain a pre-fermented product C; adding the raw material A into the pre-fermented product C, continuously fermenting, and drying to obtain a powdery fermented product D; then extracting, and removing an extracting agent and grease to obtain a solid E; adding the solid E into an acid solution, and hydrolyzing to obtain a colloidal solution F; then adding metal ions,and reacting to obtain the amino acid fertilizer. According to the invention, the method can effectively improve the yield of amino acid and the yield of the amino acid metal ion chelate fertilizer, is simple in process and easy to control, and is suitable for large-scale treatment of animals died of illness to produce the amino acid fertilizer.

Description

technical field [0001] The invention relates to a technology for harmless treatment of animal corpses, in particular to a method for producing amino acid fertilizers from dead animals. Background technique [0002] With the continuous transformation of the production mode of animal husbandry and the continuous increase of the country's investment in animal disease prevention and control, the safety level of my country's animal health and its products has been continuously improved. Epidemics still occur frequently, and the harmless treatment of sick and dead livestock and poultry has become a major problem in animal husbandry. The carcasses of sick and dead animals often carry a variety of germs. If they are not handled or handled properly, the carcasses will rot quickly, causing pathogenic microorganisms to pollute the air, water and soil, causing the spread and spread of diseases, and easily causing pathogen transmission and cross-infection. Traditionally, incineration, la...

AI Technical Summary

Problems solved by technology

At present, the methods of using dead animals to produce amino acid fertilizers mainly include acid hydrolysis, alkali hydrolysis or enzymatic hydrolysis of proteins to obtain amino acids, and then chelate with metal ions, but the amino acids obtained by hydrolysis are easy to decompose, and alkali hydrolysis will affect most Amino acids cause damage, resulting in a decrease in the yield of amino acids; enzymatic hydrolysis requires a large amount of enzymes, high cost, and is not suitable for large-scale production
