State-of-the-Art Facilities,
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.

Our Certifications

We are in the process of expanding our GLOBAL G.A.P. (Good Agricultural Practices) certification to include hemp farming, a rigorous certification process that considers worker and contractor health; safety and welfare; sustainable farming and land management practices; reporting systems; hygiene and food safety; and complete traceability. All of our 2020 crop will be GLOBAL G.A.P. certified.

Both our farms and processing plants are certified to handle and process both organic hops and hemp. Again, this requires attention to detail: complete separation and traceability of the different products, following approved organic processing and farming procedures, and a commitment to clean and well-organized facilities.

All of our processing plants operate under a Quality Management System (QMS) that is ISO 9001:2015 Management System certification, an internationally recognized standard that validates the quality of our manufacturing, including everything from our organizational structure and leadership to systems to improve customer satisfaction.

By virtue of our compliance with both the ISO 9001:2015 standard, as well as the GLOBAL G.A.P. standards, we are a recognized sustainable organization and quality-driven organization operating in a sustainable manner.

In addition, we are currently registered with EcoVadis and Sedex, and the Sustainable Agriculture Initiative (SAI), to ensure the transparency of our sustainability and corporate social responsibility practices through our supply chain. We are also certified with Kosher and Halal to comply with the growing and processing standards for those certifications.

Feel free to contact us with any questions you may have. We will update this information as it changes.
