Full-Process Supercritical CO2 Extraction System for CBD

The CBD extraction process plays a crucial role in industrial-scale hemp processing. This project introduces a supercritical CO2 extraction system with a daily processing capacity of 5 tons of cannabis biomass, covering the complete workflow from raw material pretreatment to final packaging of CBD oil and CBD isolate.

I. Project Overview

The system integrates:

  • Raw material pretreatment
  • Supercritical CO2 extraction
  • Winterization & dewaxing
  • Decarboxylation
  • Solvent recovery
  • Molecular distillation
  • Crystallization & milling
  • Final packaging

This ensures a continuous, fully automated CBD production line, designed for efficiency, product purity, and compliance with GMP standards.


For large-scale CBD production, choosing reliable equipment is critical. Our full-process system, designed for 5 tons/day capacity, integrates supercritical CO₂ extraction, winterization, distillation, crystallization, and final packaging.
