Building a CBD extraction production line requires careful preparation before installation. From factory layout to raw material treatment and equipment setup, every step affects the quality of CBD oil production. By using supercritical CO₂ extraction equipment, producers can ensure efficiency, safety, and high purity of the final CBD oil.
1. Factory Requirements and Layout Design
Before installing the CBD extraction production line, the factory must meet specific conditions:
- Height & Space: Supercritical CO₂ extraction equipment usually requires 8–10 meters of effective height.
- Power Supply: Stable single-phase 220V/50Hz or three-phase 380V power.
- Layout: Divide into raw material storage, extraction area, winterization and decarboxylation zone, distillation and purification section, and packaging area.
- Utilities: Cooling systems, ventilation, and safety devices must be ready before installation.
2. Key Functions in the CBD Extraction Production Process
Raw Material Preparation
- Function: Hemp flowers must be dried and ground, with moisture reduced to 10–15%.
- Why: Excessive water content (e.g., 58%) lowers extraction efficiency and risks blockages.
Supercritical CO₂ Extraction
- Function: At high pressure (20–40 MPa) and controlled temperature, CO₂ dissolves active compounds from hemp.
- Why: Ensures selective extraction, preserving heat-sensitive cannabinoids.
Separation & CO₂ Recycling
- Function: Reduce pressure and temperature to separate compounds, while recycling CO₂.
- Why: Minimizes solvent loss and production costs, supports green production.
Winterization
- Function: Use ethanol at low temperature to remove waxes and lipids.
- Why: Improves the purity and stability of CBD oil.
Decarboxylation
- Function: Heat CBDA into active CBD.
- Why: Only after decarboxylation does CBD reach full biological activity.
Distillation & Purification
- Function: Molecular distillation or thin-film evaporation removes impurities and solvents.
- Why: Produces high-purity CBD oil suitable for pharmaceuticals or cosmetics.
Quality Control & Packaging
- Function: Test CBD content, residual solvents, and heavy metals. Use vertical packaging machines or bottling systems.
- Why: Ensures consistency, safety, and compliance with international standards.
3. Installation and Commissioning
- Perform 3D layout design before installation.
- Test pressure, temperature, and flow during commissioning.
- Train operators on the HMI control system, inverter settings, and emergency shutdown.
4. Conclusion
Installing a complete CBD extraction production line is more than equipment assembly; it requires careful planning of factory conditions, raw materials, and process functions. With advanced supercritical CO₂ extraction equipment, producers can achieve efficient, safe, and high-quality CBD oil production.
During the installation and preparation of a CBD extraction production line, it’s essential to understand the differences between various extraction methods. For example, our detailed comparison between CO₂ extraction equipment and BHO explains how supercritical CO₂ systems offer advantages in purity, safety, and efficiency, helping producers make informed decisions when selecting equipment for cannabis processing.
