● Dried and crushed cannabis flowers and leaves
● Extract by ethanol extraction or supercritical extraction
● Freezing, decarboxylation and other pretreatment
● Molecular distillation separation and purification
● Chromatography to remove THC or further purify CBD
● Crystallization to obtain high purity CBD

| Extraction Efficiency |
Around 85% |
Around 60%~70% |
| Increase ↑15% |
| Extraction Equipment |
2 Sets of Centrifuge Extractors (Usually with higher efficiency) |
Traditional Soaking Reactors |
| Countercurrent Extraction method with high efficiency |
Low Efficiency |
| 99% Crude Oil Extraction Rate after the Countercurrent Extraction |
A large amount of crude oil remains in the wet biomass |
| Crude Oil Purify Process |
Including Degumming, Chlorophyll, Proteins, Sugars, Phospholipids removing process |
Only wax removing but not completed |
| No need to clean and maintain the short path distillation machine Frequently. |
Easy to Coke and cause the blocking in the distillation process, even scrap the short path distillation machine. |
| THC Remediation |
Destroy THC to 0.2% according different requirement |
HPLC Only (High Performance Liquid Chromatograph) |
| Adopt HPLC (High Performance Liquid Chromatograph) or SMB if request the THC lower than 0.2% |
| Solvent Regeneration |
Rectification Column to regenerate the Ethanol when purity less than 85% |
Abandon/Waste |
