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)

Principles of high speed rotational air 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 rotational air flow grinding technology

Round particle grinding by friction-between-particles method – Able to grind to several ㎛ (micrometer) depending on material
-Provides a smooth taste due to circular particle grinding
→ Micro size particles for high absorption
Grinding without thermal denaturation – Minimize heat(approx. to 30℃) through the casing cooler to grind high-fat, high-sugar, and high-fiber ingredients without loss of nutrition→ Preserves original taste and nutrition
Grinding of Multiple Ingredients – Capable of grinding even when various ingredients are put in together
Wide grinding range – High-fat ingredients such as soybean and brown rice
– High-fiber ingredients such as barley shoot
and wheat shoot
– Seafood: Anchovy, shrimp, crab, fish, shellfish, kelp,
seaweed and etc.
– Vegetables: Dried vegetable and fruit, roots and stems
– Minerals: Pearl, oyster shell, scallop shell, and mineral
matter such as coal and soil
Sealed Grinding – Prevents foreign substances from mixing into by materials colliding with each other in friction-between-particles grinding method through air flow
