Problems solved by technology

In order to solve the defects that the traditional crushing process cannot crush pearls and shells ultra-finely and prepare ultra-fine powders by chemical methods, a new process must be used to complete the ultra-fine crushing of pearls and shells to the nanometer level, and fully retain pearls and shells. Biological activity of biocalcium from shell nacre

Embodiment 1

[0014] Embodiment one is the method for raw material manufacture nanometer pearl powder biological calcium buccal tablet with pearl:

[0015] 1. Pearl cleaning: pick out the sand particles and diseased pearls mixed in the raw pearls, then wash the pearls with water and inject O 3 Disinfection and sterilization;

[0016] 2. Low-temperature drying: Dry the washed pearls below 80°C to prevent excessive temperature from destroying the biological activity of the nacre;

[0017] 3. Coarse crushing of pearls: Use a double-roller groove surface fine crusher to coarsely crush the dried pearl shells to about 100 meshes;

[0018] 4. Superfine crushing: Put 100 mesh pearl coarse powder into the stirring ball mill, add appropriate amount of water and 0.5-5% of the powder weight of organic silicon oil as a dispersant, and rely on the mechanical stirring rod in the grinding chamber to drive the grinding media to move. Extrusion force and shear force are used to peel off the pearl powder an...

Embodiment 2

[0036] Embodiment 2, using fresh shells as raw materials to manufacture nano-pearl shell powder buccal tablets, the fresh shells include pearl shells, oyster shells, abalone shells, etc., and first clean the silt debris outside the shells.

[0037] 1. First, remove the black cortex on the outer layer of the shell. Wash it with alkali at room temperature to remove the black cortex. The white calcareous layer of the shell is completely exposed, soak it in weak acid, and then rinse it with water until neutral, about PH7. and inject O 3 Disinfection and sterilization;

[0038] 2. Low-temperature drying: Dry the washed shells below 80°C to prevent excessive temperature from destroying the biological activity of the nacre of the shells;

[0039] 3. Coarse crushing of shells: the dried shells are roughly crushed to about 100 mesh with a double-roller groove surface fine crusher;

[0040] 4. For ultrafine grinding, put 100-mesh shell powder into a stirring ball mill, add appropriate...

Abstract

The making process of nano level pearl powder and shell powder includes cleaning pearl and shell, low temperature stoving, crushing into meal, packing and sterilization, and features that it also includes the following intermediate steps: superfine crushing, crystal layer separation, liquid phase intercalation, nano treatment, drying and depolymerization and deactivation of powder surface. The prepared pearl powder and shell powder has maximum grain size of 300 nm, with 30-50 % of the powder having grain size smaller than or equal to 100 nm. This kind of nano level pearl powder and shell calcium powder has wide application in medical health care and cosmetics.

Description

technical field [0001] The invention relates to a method for physically processing and preparing nano-scale pearl powder or nano-shell powder. Background technique [0002] Pearls are rich in protein, more than 20 kinds of amino acids, biological calcium and trace elements needed by the human body, and are traditional valuable traditional Chinese medicines and nutritional health products. Pearl shells, oyster shells, abalone shells, and pearls have a material structure similar to nacre. Since the nacre is a hard concentric lamination structure, the distance between the layers is only at the nanometer level. The traditional processing method, no matter how much it is ground, cannot open the solid structure between the nacre layers. The pearl particles are still multi-layered, with an average particle size of 10 μm. above. If nano-scale pearl powder or nano-scale shell bio-calcium powder is prepared by high temperature or hydrolysis, the active ingredients of pearls will be ...
