Standard Operating Procedure

The 8-Stage Precision Extraction Process

From botanical identification to cleanroom packaging, every manufacturing batch undergoes systematic control to guarantee active ingredient potency, micro-cleanliness, and batch uniformity.

STEP 01

Raw Materials

Origin-authenticated botanical and mushroom materials thoroughly inspected for active assay, moisture, pesticide residues, and heavy metals.

STEP 02

Extract

Multi-stage aqueous or hydroalcoholic extraction executed inside closed stainless-steel reactors under exact time and temperature control.

STEP 03

Concentration

Continuous low-temperature vacuum concentration protecting thermo-sensitive actives and effectively recovering extraction solvents.

STEP 04

Macroporous Resin Adsorption Purification

Adsorb

Macroporous resin chromatography selectively purifying bioactive monomers and eliminating inert polysaccharides and ash.

STEP 05

Drying & Spraying

Instantaneous spray drying atomizing liquid concentrates into free-flowing, fully soluble, uniform extract particles.

STEP 06

Smashing & Sieving

High-efficiency pulverization coupled with mechanical vibration sieves ensuring target particle size distribution (80–200 mesh).

STEP 07

Mixing

Sanitary three-dimensional dynamic powder blenders ensuring homogeneous active distribution across multi-ton production batches.

STEP 08

Finished Product

Cleanroom packaging in food-grade polyethylene-lined foil bags or fiber drums with metal detection and lot seal inspection.
