Embodiment 1

[0039] Step 1: Centrifuge, put the fresh eggshells separated by beating eggs into a centrifuge for centrifugation to remove the remaining egg liquid in the eggshells, and the centrifuge speed is 1000rpm.

[0040] Step 2: Cleaning, putting the centrifuged eggshells into the first mixer through an auger for stirring and cleaning, further removing the remaining egg liquid in the eggshells, and washing repeatedly three times until the water is clear.

[0041] Step 3: Sterilize, put the cleaned eggshells into the second mixer containing disinfectant with an effective chlorine concentration of 200ppm through the auger and soak for 10 minutes to sterilize the eggshells.

[0042] Step 4: Filtration, first put the sterilized eggshells into the third mixer through the auger for stirring and cleaning, remove the chloride ions in the water, and wash until the residual chlorine concentration is below 0.3mg / L, and then pass the cleaned eggshells through the auger Long feed into the filter t...

Embodiment 2

[0050] Step 1: Centrifuge, put the fresh eggshells separated by beating eggs into a centrifuge for centrifugation to remove the remaining egg liquid in the eggshells, and the centrifuge speed is 2000rpm.

[0051] Step 2: Cleaning, putting the centrifuged eggshells into the first mixer through an auger for stirring and cleaning, further removing the remaining egg liquid in the eggshells, and washing repeatedly three times until the water is clear.

[0052] Step 3: Sterilize, put the cleaned eggshell into the second blender containing disinfectant with an effective chlorine concentration of 250ppm through the auger and soak for 20 minutes to sterilize the eggshell.

[0053] Step 4: Filtration, first put the sterilized eggshells into the third mixer through the auger for stirring and cleaning, remove the chloride ions in the water, and wash until the residual chlorine concentration is below 0.3mg / L, and then pass the cleaned eggshells through the auger Long feed into the filter t...

Embodiment 3

[0061] Step 1: Centrifuge, put the fresh eggshells separated by beating eggs into a centrifuge for centrifugation to remove the remaining egg liquid in the eggshells, and the centrifuge speed is 3000rpm.

Abstract

The invention discloses a preparation method of eggshell powder and a special device for realizing the method. The preparation method of the eggshell powder comprises ten steps of centrifugation, cleaning, sterilization, filtration, coarse crushing, shell-membrane separation, fine crushing, drying, sterilization and recovery. The efficiency of obtaining the eggshell powder through the method is higher, the purity of the eggshell powder obtained after separation is higher, and the separation cost is low; and the original physical and chemical properties of a lime shell and an eggshell membrane can be retained to the greatest extent, and the full utilization of the eggshell membrane can be realized.

Description

technical field [0001] The invention relates to a method for preparing eggshell powder and special equipment for realizing the method. Background technique [0002] The eggshell accounts for 10% -12% of the whole egg mass, and is composed of three parts: the upper shell membrane, the true shell, and the 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. [0003] The annual output of poultry eggs in the world reaches 60 million tons, of which China has nearly 30 million tons. If eggshells account for 11% of egg mass, th...
