Cutting Edge Practices
Our long history of botanical knowledge, our large processing capacity, and our quality standards have earned us valued customers throughout the world. Our various customized processes have been in operation for over 30 years, lending us a marked expertise in the emerging hemp industry. Using CO2 as a solvent allows the production of a pure, clean, high-quality oil in a safe manner while excluding the residual harsher solvents that remain in the finished product from other extraction methods. The multiple large-scale extraction vessels we use for hemp processing enable us to produce several thousand pounds of hemp biomass daily. Our botanical supercritical CO2 extraction process follows the Good Manufacturing Practices dictated by the U.S. Food & Drug Administration.
Hemp Processing Methods
Drying & Baling
At our hemp processing facility, the ranch team takes the biomass and loads it into the drying beds to be dried and baled. This process begins with a high-capacity drying system, allowing us to dry consistent, large-volume batches. Our natural gas-powered air dryers blow hot air upwards through perforated floors at about 140°F. Setting the temperature at this level, we are able to preserve the vital components of the plants, while still achieving the optimal aridity. The entire drying process typically lasts between 8 to 10 hours, depending on the moisture levels of the biomass. Once dry, the team then loads the biomass into baler machines, which roll the dried biomass into large, cylindrical hemp bales.
After drying and baling our hemp, we transport it to our pellet plant for pelletization. Our machines begin by grinding the biomass into a fine powder, then pushing the material through a hammer mill to create pellets. Our team then packages the pellets into super sacks or mylar bags of varying sizes, depending on the needs of our customers. This process enables us to have our material extraction vessel ready, while maintaining the integrity of our biomass and its beneficial compounds.
CO2 Hemp Extraction
Once we have pelletized the biomass, our team transfers the pellets into large cylinders, where our equipment introduces CO2 at higher pressures and temperatures. Hempsteiner has the ability to process under subcritical (low pressure, low temperature) or supercritical (high pressure, high temperature). By having versatile pressure and temperature conditions, we can optimize our process, extracting critical components from the hemp, like the cannabinoids and terpenes. As such, we can offer crude hemp oil in both decarboxylated and natural non-decarboxylated forms.
