- Freezing the plant material to make the trichomes brittle and easier to detach.
- Gently agitating the frozen material to dislodge the trichomes without damaging them.
- Filtering the mixture to separate the trichomes from the plant matter.
- Collecting the trichomes, which can then be further processed for extraction.
For successful mechanical separation, it’s crucial to use the right equipment and techniques to preserve the integrity of the trichomes. Additionally, maintaining optimal temperature and humidity levels is essential throughout the process.
3. Supercritical CO2 Extraction
Preparation: The cannabis is ground and placed in an extraction vessel.
Extraction: CO2 is pressurised until it reaches a supercritical state, and then passed through the cannabis, separating the essential oils and compounds.
Separation: The CO2 and extracted compounds are separated, with the CO2 returning to its gaseous state, leaving behind a concentrated extract.
Collection: The extract is collected for further processing and purification.
For optimal supercritical CO2 extraction, maintain precise pressure and temperature conditions, and use high-quality cannabis to yield premium extracts.
