Unlock the Full Potential of Your Biomass with Ethanol Extraction
Western States offers high-performance botanical centrifuges designed specifically for ethanol extraction. Engineered for precision and reliability, our equipment enables cannabis and hemp processors to achieve maximum cannabinoid and terpene retention while reducing post-processing time and cost.
What Is a Botanical Extraction Machine?
A botanical extraction machine—most often a centrifuge—is used to extract essential oils, cannabinoids (CBD, THC), and terpenes from cannabis and hemp biomass. These machines spin the biomass and solvent at high speeds (up to 1500 RPM) to separate valuable compounds from plant material efficiently.
Our centrifuges are specially engineered for ethanol extraction workflows, maintaining cold temperatures to protect delicate compounds and ensure a clean, potent extract.
Why Choose Ethanol Extraction Over CO2 or BHO?
Compared to CO₂ or butane (BHO), ethanol extraction offers significant advantages:
- Cost-Effective: Lower capital investment and operating costs
- High Throughput: Ideal for both large-scale and small-batch operations
- Safer: Ethanol is food-grade and easier to handle than volatile hydrocarbons
- Preservation of Cannabinoids and Terpenes: Especially when performed at cold temperatures
- Cleaner Crude Oil: Reduces the need for winterization and other post-processing
Ethanol extraction, currently, is the easiest way to extract terpenes and cannabinoids from cannabis plant matter with the lowest costs and risks of failure. It is also extremely scalable working incredibly well with both large-scale outfits and smaller boutique extraction outfits. It has an overall efficiency rate of over 90% and is customizable to produce the purity and quantity desired. It is the most cost-effective method of cannabis extraction. Botanical Centrifuge systems from Western States, like the WSB-15 and WSB-40, provide a lower start-up cost, are more efficient, are easier to operate, and draw out more cannabinoids and terpenes.
What Makes Ethanol Extraction So Effective?
Ethanol is an efficient polar solvent that dissolves cannabinoids and terpenes while leaving behind undesirable elements such as:
- Chlorophyll
- Waxes
- Lipids
This results in a purer, clearer extract, especially when ethanol is used at cryogenic temperatures (−40°C or below). This method protects terpenes, which are highly volatile and degrade under heat, and retains acidic cannabinoids like THCA and CBDA, improving the overall extract quality.
Our centrifuges can be integrated with different ethanol extraction systems and boast an incredible performance rate due to our in-house manufacturing of machine parts and experience with centrifuges. With methods such as carbon and co2 extraction costing more money and even tighter specialized machines, Western States is dedicated to creating long-lasting and robust machinery that provides long-term value. In the event that our machinery doesn’t last as long as you’d like, Western States is capable of swiftly replacing faulty parts and even upgrading machines that have worked past their prime.

Why Western States?
With over 100 years of industrial centrifuge experience, Western States stands out by offering:
- Legendary Reliability: Our machines are engineered in the USA using stainless steel and corrosion-resistant components
- Custom Engineering: We tailor systems to your biomass, extraction goals, and solvent strategy
- Unmatched Customer Support: From design to implementation and upgrades
- Proven Performance: Our systems are in use by top-tier producers across the hemp and cannabis extraction industry
Each machine Western States produces comes with a reliability guarantee. Not only do our machines function within the maximum and minimum bounds of the solvent extraction method utilized, but our machines are also specialized to maximize the quality of cannabinoids extracted through ethanol extraction. Because of the nature of ethanol extraction, each WSB machine is coated with external and internal stainless steel surfaces with a 39 Ra, or better (Electropolish optional), to prevent corrosion from ethanol. Each machine is treated to be part of a high-speed efficient ethanol extraction system generating a 900 G separation force. With solvent recovery a top priority for many companies, the WSB-15 and WSB-40 are outfitted to withstand up to -40 degrees F and have a maximum temperature of 105 degrees F.
Western States machines are made with over 100 years of experience in extraction industries. This will positively impact your bottom line by providing quality engineered, manufactured, and tested equipment which will save your company valuable time and resources and create valuable automation opportunities. By ensuring we provide the best solution for your business as well as the best service we will be able to minimize downtime and optimize your potential productivity.
