Necessity of hyperfine powder processing


Shortens extraction process of active ingredients and improves extraction efficiency (Maximize extraction efficiency of active ingredients)

Selection → grinding → extraction → concentration → Vacuum dry (powder) → packaging > dry → ultra-fine grinding → packaging.
Dissolve 47.8% of water-soluble ingredients among entire nutrients when extracting boiled red ginseng > Intake insoluble ingredients when doing hyperfine grinding.

[Analysis result of Korea Food Research Institute] Nutrition contents of cabbage powder liquid compared to cabbage juice:
Fiber (36.82 times), Vitamin E (19.85 times), Flavonoid (7.33 times), Calcium (4.37 times)


Significantly improves solvency of middlings and mixing power with other materials & Maximize processing efficiency

Conserve unique nutrients of raw materials (Minimize nutritional loss due to thermal denaturation) → Hyperfine powder processing of agricultural products without thermal denaturation of active ingredients, color, scent and flavor → Decrease particle size → Improve nutrient texture.
Concentrate nutrients to absorb by using particle size and density difference


Hyperfine powder process of raw materials → Maximize in vivo absorption → Minimize nutrient loss

Elephant, rhinoceros → Decompose plant cell wall (cellulose) → Able to extract all nutrients from plant cell to absorb.
Human → No breakdown enzyme of cell wall (cellulose) → Physically decompose to absorb nutrients in cell wall → Hyperfine powder process (Principle of digesting food well when chewing it finely)

Grinding principle of high speed rotary fluid flow grinding technology


1. Grinding by friction method using high speed rotary fluid flow → Able to process ultra-fine grinding of raw materials with a lot of fat without any destruction of nutrients due to thermal denaturation

2. Fine powder recovery method using centrifugal force

Recovery fine powder, sorting area, grinding area, rotation area, input raw materials, introduction area, second rotary blade, first rotary blade

Characteristics of high speed rotary fluid flow grinding technology

Fuselage friction circular grinding Grind available materials with circular particle to several ㎛to provide soft texture
→ Hyperfine powder processing that is absorbable
Grinding with no thermal denaturation Grind materials that contain fat, sugar and fiber with no changes in ingredients due to thermal denaturation by minimizing heat (about 30℃) with casing cooling
→ Keep the flavor and nutrients of raw materials as it is
Complex grinding for multi variety Complex grinding is possible by putting various raw materials at the same time
Wide grinding range
  • Materials with a lot of oil such as soybean and brown rice
  • Materials with a lot of fibrous such as barley sprout and wheat sprout
  • Seafood, anchovy, shrimp, crab
  • Seaweed, kelp, fusiformis, sea mustard
  • Vegetables, dried vegetables (including fruits), roots and stems
  • Mineral, pearl, oystershells, scallop shells and mineral matters (charcoal, soil)
