Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protein degradation reactors, and more specifically to a special reactor for degrading animal protein using a biological enzyme method. Background Art
[0002] Meat and bone meal, the main raw material of animal protein, is a byproduct of high temperature and high pressure drying of dead livestock and poultry. Its main use now is to make fertilizers directly or indirectly. Because plants cannot directly absorb protein, it needs to be converted into amino acids or short peptides before it can be absorbed and utilized, and the fertilizer effect is very slow. Common methods for hydrolyzing meat and bone meal include acid hydrolysis, alkaline hydrolysis, high temperature and high pressure hydrolysis, and enzymatic hydrolysis. Among them, enzymatic hydrolysis has the most promotion value due to its mild reaction conditions and good quality of enzymatic hydrolysis products.
[0003] A lot of fat will be brought into the meat and bone meal during the processing, which will affect the efficiency and quality of the enzymatic hydrolysis, so it needs to be removed before entering the enzymatic reactor. The common method of removing fat is the layering method, but in the production process, due to insufficient stirring and standing time, there will still be a lot of fat remaining in the protein liquid. In addition, the presence of sugar, protein, inorganic salts and other substances in animal protein during the enzymatic hydrolysis process will cause a lot of foam to be generated during the enzymatic hydrolysis process. If these foams cannot be eliminated in time, they will affect the normal progress of the enzymatic hydrolysis reaction, and the traditional method of adding defoaming agents will affect the efficiency of enzymatic hydrolysis.
