What Is Supercritical CO2 Extraction
The Supercritical CO2 extraction process creates phase changes in carbon dioxide utilizing temperature and pressure. CO2 is known as a “tunable solvent” making it extremely versatile for creating a multitude of end products by controlling temperature and pressure. These phase changes create an environment to drop out differing weights of components in the plant material.
Application of CO2 Extraction
Supercritical CO2 is increasingly being used as a cheap, recyclable, and environmentally safe industrial solvent for creating high quality:
Fruit and nut extracts
Fruit and nut aromas
Tobacco extractions for e-cigarettes
Hop-oil extraction for beer
Oil extractions from algae (as an alternative energy source)
What Are the Benefits of CO2 Extraction
Simply speaking, CO2 extraction is the cleanest, safest method for extracting plants such as hops, cannabis and a wide range of nutraceuticals and organic crops.
1. CO2 extraction is that CO2 oils are highly customizable. Industrial concentrate makers can make pure cannabis extracts with the consistency of oil, shatter, budder or wax just as easily with the same CO2 machine simply by varying and fine tuning the temperature, pressure, solvent-to-feed ratio and the flow rate during the extraction process.
2. As far as non-polar solvents are concerned, CO2 is among the safest. In fact, the FDA has labelled CO2 safe for industrial extractions, making it a much less controversial solvent than petroleum based hydrocarbons such as butane or propane.
3. Another benefit of CO2 extraction is that running supercritical liquid CO2 through reefer kills any microbial bacteria, mold, mildew or insect mites that shouldn’t be in your weed in the first place. This guarantees that your concentrates will be cleaner and healthier for you to consume.
How Does This Extraction Way Work
When you use supercritical co2 extraction machine, place plant matter of the highest quality into it. Once the carbon dioxide is super cooled, it is pushed through an extraction tube containing the plant matter, which leaves behind only the cannabinoids, terpenes, and trichomes. When this mixture is warmed, the CO2 evaporates, leaving behind pure cannabis oil.
