Poultry eggshell membrane separation device

Abstract

The invention relates to the technical field of shell membrane separation, in particular to a poultry eggshell membrane separation device which comprises a base and a cover, a groove is formed in the base, the base comprises an inner shell and an outer shell, a heating cavity is formed between the inner shell and the outer shell, a water collecting tank is arranged at the bottom of the inner shell, and an annular air bag is arranged on the wall of the outer shell. An air cylinder with an opening in the upper end is vertically arranged in the cover body, a piston is connected in the air cylinder in a sliding mode, a push rod with the upper end fixedly connected with the piston is vertically arranged in the air cylinder, the lower end of the push rod is fixedly connected with a suction cup, and the outer wall of the cover body is fixedly connected with a sprayer and a cold water tank. A water inlet of the sprayer communicates with the cold water tank, and an air inlet of the sprayer communicates with the air outlet through an air pipe. The under-shell membrane obtained through separation is complete and large in area, the composition structure of the under-shell membrane cannot be damaged, meanwhile, fine egg shell particles cannot be embedded in the obtained under-shell membrane, and the texture is pure.

Description

technical field [0001] The invention relates to the technical field of shell membrane separation, in particular to a poultry egg shell membrane separation device. Background technique [0002] The eggshell is composed of the true shell and the shell membrane. The shell membrane includes the upper shell membrane and the lower shell membrane. The upper shell membrane is also called the gummed film, which covers the outer surface of the true shell. Such as glucosamine, keratin, hyaluronic acid and other substances, can be widely used in medicine, skin care cosmetics and other fields. [0003] The research and development of the subshell membrane needs to take out the subshell membrane from the eggshell first. The separation of the shell membrane mentioned in this article refers to the separation of the subshell membrane from the eggshell. The egg shell mentioned in this article refers to the shell and the epishell membrane covering the outer surface of the true shell. Existin...

AI Technical Summary

Problems solved by technology

Existing shell-membrane separation devices usually use the method of crushing eggshells and then soaking them in a separating agent to separate the true shell from the subshell membrane. The subshell membrane obtained by this method is relatively fine and has poor integrity. The chemical separation agent used in this method is easy to destroy the composition of the subshell membrane, and this separation method requires subsequent screening of the finely divided shell membrane mixture several times in order to completely separate the subshell membrane from the true shell, and the finely divided true shell is crushed when the eggshell is crushed. The shell is easily embedded in the soft subshell membrane, which is not easy to remove, so that the obtained subshell membrane contains impurities. Experimental research with the subshell membrane containing impurities will affect the enzymatic extraction of keratin enzymes from the subshell membrane. The determination of the content causes misjudgment. Secondly, in the experimental research, sometimes a larger subshell membrane is needed for research and analysis. It is obviously impossible to obtain a pure and larger subshell membrane to meet the needs of experiments and research. analysis needs
