Our extraction method

 

Hands down, one of the most important and beneficial decisions we’ve made so far is using supercritical CO2 as our extraction method. Why? Because it ensures that we are providing the purest and cleanest CBD products on the market. The supercritical CO2 process uses Carbon Dioxide that has reached its critical pressure and temperature limit as the extracting solvent. But what makes this method so special? We can’t speak for everyone, but we love this method for a couple of reasons: it has minimal environmental impact and low levels of toxicity. In fact, the FDA has declared CO2 extraction as a generally recognised as safe, (GRAS) method that is a common staple in the food industry.

Professionally trained and experienced lab technicians use special equipment to pull off supercritical C02 extraction properly. This method at its core is the process of creating pressure and temperature changes in carbon dioxide, that is then cooled and compressed at around 10,000 pounds per square inch (psi)— which is very a high compression rate. It is these extremes that propels it into the supercritical territory of being converted into a liquid and a gas. Even more, this process prevents any damage to heat-sensitive compounds like vitamins, enzymes, and cannabinoids, thus allowing consumers to receive the full range of benefits this amazing plant has to offer.

Pump forces pressurised CO2 at the optimum temperature, and in the liquid supercritical state (ScCO2), into the extractor chamber.

The supercritical carbon dioxide acts as a solvent with the cannabis, dissolving the cannabinoid compounds it contains.

The ScCO2 carries the cannabis oil particles past a pressure release valve into a separator.

In the separator, the pressure is lower and the carbon dioxide reverts back into a gas, and separates from the cannabis oil.

The Carbon Dioxide gas rises out of the oil and is routed back to the CO2 tank to be used again in a closed loop system.

The cannabis oils, waxes and resins descend in the separator where they are captured in a collection vessel.

The resulting substance is processed further into various products, such as pure CBD-rich cannabis oil, free of any solvents.
