There are many useful substances, such as Terpenes and Cannabinaoids. As the demand for cannabis products increases and diversifies, extracting these substances becomes crucial for recreational and Medical Use. In order to isolate the active materials in cannabis there are two main ways of extraction.
A producer will require access to a cannabis oil extraction machine.
It’s worth noting that there are several types of these machines on the market. So care needs to be taken when making a selection. They vary in size,price,processing speed,user-friendliness and durability.
The supercritical(subcritical) CO2 method uses carbon dioxide under pressure and ambient temperature to isolate, preserve and maintain the purity of the oil. CO2 extraction doesn’t like water in the source material so drying the cannabis properly beforehand is essential. Some view this method as leading the extraction industry. When done right the product is safe , potent and free of chlorophyll. The method achieves self-ready oil straight from the extractor with little effort.
CO2 Extraction Procedure
To perform an extraction, the plant material must be ground and placed into an extraction vessel. CO2 gas undergoes high temperature and pressure. A pump then forces supercritical CO2 into the extraction vessel where it meets the plant and breaks the trichomes allowing it to dissolve part of the plant material.
Food grade ethanol can be used to create cannabis oil appropriate for vape pen cartridges and other products, however, this extraction method destroys some beneficial compounds including terpenes. These have health benefits that are favored by product makers.Over extraction of cannabis can also occur
Ethanol Extraction Procedure
The cannabis plant material is placed in contact with the alcohol specifically ethanol and allowed to soak together thoroughly. The soak time should be adequate to enable the squeezing effect of the ethanol to withdraw the cannabis oil. Afterward, you are free to remove the residual plant materials through sieving. You may need to filter the resulting liquid effectively. The alcohol component of the fluid is eliminated by the evaporation process, leaving behind the pure cannabis oil.
It is important to realize that cannabis is not the only Source of these valuable compounds.
Much of the intellectual property in the cannabis world has to do with tweaking and automating extraction methods.
There are many ways to extract your Essential Terpenes and oils from plants. It is up to each producer to choose a method based on their desired product. We believe that CO2 is the way to go for scale.
