Standardized Manufacturing, Advanced Machinery & Testing Apparatus
Explore our complete botanical workflow: from raw material harvesting, pressurized extraction, and column purification, to laboratory instrument release.
1. Raw Materials Inspection
Direct sourcing with origin verification, physical screening, moisture limits, and preliminary identity confirmation.
2. Solid-Liquid Extracting
Purified water or food-grade ethanol extraction with automated thermal control to preserve fragile botanical active fractions.
3. Vacuum Concentration
Continuous low-temperature vacuum evaporation concentrates active compounds while safeguarding thermolabile constituents.
4. Column Purification
Macroporous adsorption resins and filtration systems isolate target molecules and eliminate inactive organic residues.
5. Spray & Vacuum Drying
Centrifugal atomization in filtered positive-pressure chambers yields instant-dissolve, free-flowing micro-powders.
6. Precision Pulverizing
Ultra-fine impact milling controls particle size distribution suited for capsules, tableting, or ready-to-drink beverage mixes.
7. Vibrating Mesh Sieving
High-frequency grading screens ensure uniform granularity (80 to 450 mesh) coupled with in-line rare-earth magnetic separation.
8. Homogeneous Mixing
Three-dimensional powder blenders guarantee homogeneous active content across multi-thousand kilogram production batches.
9. Finished Product Pack
Double food-grade inner aseptic PE bags sealed in tamper-evident fiber drums or custom retail barrier pouches with batch lot COAs.
