Fulfilling the promise of CO2

Green Mill's deep Pittsburgh CO2 roots deliver best-in-class performance and efficiency.

 
Green Mill’s fractionation technology has the ability to control all parameters with precision, providing for a wide array of high quality products with minimal downstream processing. It was the final key we needed to unlock our scale-up potential.

Extract More With Higher Pressures

Our 7,500 psi pressures mean higher efficiency during your extractions, leaving less money behind in the vessel. Our custom-designed, 4-piston, liquid displacement pump is compact, powerful, smooth, reliable, and energy-efficient. Further boosting efficiency is a patent-pending dispersion plate that evenly directs CO2 through your raw material.

Forget About Babysitting

True Automation mirrors your whole system on a touchscreen and allows you to control it entirely through the connected PC. Enter temperature and pressure settings for each vessel independently, plus flow rate, extraction run time, and collection time. No wrenching, hammering, or anything that requires tools, at any time during the extraction. Press Start, and walk away. Anyone can quickly learn to operate our systems and run extractions without assistance.

Meet Demand Sustainably

This is the fastest-growing industry in the world. Any new business must be prepared to scale up, from the start, and into the foreseeable future. Only the business models that adapt to this reality will survive the coming tsunami of demand. But simply making machines larger, as our competitors do, adds a massive burden in terms of operations and energy consumption. Green Mill scales your extraction throughput and keeps you competitive without sacrificing efficiency or leaving you with obsolete equipment.

Produce Three Oils at Once

You will save significant time in the post-extraction lab thanks to Green Mill's Triple-Product Fractionation. A single run can feed three simultaneous product pipelines — high potency oil for waxes, shatter, and dabs in the first collection vessel; general oil for vapes, edibles, beverages, pills, tinctures, and topicals in the second vessel; and full spectrum oil for terpenes in the third vessel.

Always Know What Your System is Doing

Every component on your system provides data feedback on what it's doing, displayed in real-time. There are no fewer than 27 sensors sending information back and forth to the computer at all times. A coriolis flow meter measures flow. Automatic density calculation and feedback give you maximum flexibility in developing your recipes. Data logs record everything that happens on your machine during an extraction for full analysis, process development, and troubleshooting if there's an issue.

Contact Us

We love talking extraction to anyone who will listen. We're confident we can make a solid case for buying our systems, but even if you decide to buy elsewhere, we want to hear from you in the hopes that one or both of us can learn something new about this fascinating industry.
