Health artificial pearl and manufacturing method therefor

A method for manufacturing a health pearl, method comprising:

• a raw material pre-treatment step (S100) of forming a wet-ground solution by wet-grinding a functional mineral that emits anions and far-infrared rays and forming a powder for press-forming by spray-drying the wet-ground solution;
• a press-forming step (S200) of forming a core by inserting the powder for press-forming into a press-forming device and high-temperature sintering the core;
• a core polishing step (S300) of polishing the high-temperature sintered core;
• and
• a coating step (S400) of applying an artificial pearl composition to the polished core, wherein the raw material pre-treatment step (S100) includes a wet-ground solution preparation step (S110) of forming the wet-ground solution by adding 50 parts by weight to 70 parts by weight of the functional mineral to 100 parts by weight of water and wet-grinding the functional mineral to have an average particle size of 1000mesh to 1500mesh;
• and a spray-drying step (S120) of spray-drying the wet-ground solution using a spray-dryer set to an inlet temperature of 250° C. to 350° C., an outlet temperature of 150° C. to 250° C., a spray pressure of 5 kPa to 10 kPa, and a hot air volume of 0.30 m3/min to 0.50 m3/min.
