Problems solved by technology

[0003] The traditional operation method is to manually rotate the shaking head tube, so that the suction end of the shaking head tube drops with the drop of the liquid level, and stops discharging when it falls to the interface; One end is inserted into the sediment; the traditional shaking head tube is located in the clarification tank, which will hinder the stirring. The long-term force shaking head tube itself will loosen, and the motor load will increase; in order to avoid shaking the head tube when discharging Interference with the stirring shaft, the suction end of the shaking head tube is located on the side of the clarification tank for dischar

Abstract

The invention discloses a preparation method of yolk supernatant powder and an egg white extraction device thereof. The preparation method specifically comprises the following steps: cleaning fresh eggs, extracting egg white, filtering clear liquid, concentrating, sterilizing at low temperature, drying at low temperature, detecting, packaging, performing gold detection, boxing and warehousing. Thepreparation method has the beneficial effects that compared with immunoglobulin extracted from serum of mammals, the egg white extraction device has the advantages of convenience in material obtaining, relatively simple extraction method, high yield and the like; the product is good in stability, can generate acid-resistant antibodies in the aspect of immunotherapy, is stable in performance, canbe orally taken to prevent human intestinal infectious diseases, has a specific killing effect on pathogenic bacteria causing acute and chronic pharyngolaryngitis and amygdalitis, inhibits the growthof rotavirus cultured by tissue cells, and can also prevent animals from developing rotavirus gastroenteritis, which indicates that the yolk extract can be used as an antiviral antibody source to prevent and treat rotavirus diarrhea of infants.

Description

technical field [0001] The invention relates to the technical field of immunoglobulin extraction, in particular to a method for preparing egg yolk supernatant powder and a protein extraction device thereof. Background technique [0002] The traditional immunoglobulin extraction technology is extracted from serum. Since the main source of serum is obtained from animals, the production of immunoglobulin is severely limited by raw materials, and serum is expensive. Through the research of researchers, it is found that immunoglobulin Protein can be extracted from egg yolk supernatant powder. Immunoglobulin is a powder made from fresh eggs through multiple processes. It is the most ideal substitute for serum, and egg yolk supernatant powder has good emulsifying properties. It is an ideal raw material for food, high-grade feed and other products. When preparing immunoglobulin, it needs to go through the protein extraction process. During the temporary storage tank, it is necessar...
