Embodiment Construction

[0045] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0046] like figure 2 Shown, concrete implementation method is as follows in the specific embodiment 1:

[0047] Process 1: centrifugation. Put the fresh eggshells separated by beating eggs into a centrifuge for centrifugation to remove the remaining egg liquid in the eggshells. The centrifuge rotates at 1000 rpm.

[0048] Step 2: Cleaning. The centrifuged eggshells are put into a blender to be stirred and cleaned, and water is added to wash while stirring, and the remaining egg liquid in the eggshells is further removed, and the water is cleaned until the water becomes clear.

[0049] Step 3: Soak and sterilize. Put the cleaned eggshells into a disinfectant with an available chlorine concentration of 200 ppm and soak for 30 minutes to sterilize the eggshells by soaking.

[0050] Step 4: Filter impurities. The soaked and sterilized eggshells are ...

Abstract

The invention discloses a simple and economical method for separating a shell and a membrane so as to further obtain high-purity egg shell meal and the membrane, and a processing device. The method for processing the egg shell meal comprises the following steps of: removing residue egg liquid and impurities in the egg shell, drying and soaking the egg shell, and separating the shell with the membrane. The processing device comprises a drying device, a soaking device, a shell and the membrane separation device, a membrane collector, a shell collector and a circulation loop. Compared with the prior art, the method and the device enable the purity of the separated egg shell meal and membrane to be higher and the membrane to be more complete, and are lower in production cost.

Description

[0001] technical field [0002] The invention relates to a processing method and processing equipment of eggshell powder, in particular to a processing method and processing equipment for preparing eggshell powder by treating eggshells with unseparated shell membranes. [0003] Background technique [0004] The eggshell accounts for 10%-12% of the whole egg mass, and consists of three parts: upper shell membrane, true shell, and lower shell membrane. The epishell membrane, also known as the colloidal film, covers the surface of the eggshell and is formed by drying the white transparent mucus. The true shell, also known as the lime shell, is mainly composed of calcium carbonate, which accounts for about 93% of the mass of the true shell. The subshell membrane is in the inner layer of the eggshell and is composed of eggshell membrane and protein membrane. The eggshell membrane mentioned in this paper is actually the subshell membrane. [0005] The world's egg production rea...
