Green Mill Supercritical Launches New Extraction Technology

PITTSBURGH, Pa. – According to a 2018 report by Arcview Market Research and BDS Analytics, retail sales of cannabis concentrates are expected to reach $8 billion by 2022, surpassing traditional flower sales. In addition, a 2019 report by the same group anticipates U.S. sales of CBD products to reach $20 billion by 2024. To help cannabis manufacturers meet this rapidly growing demand, Green Mill Supercritical has introduced the Parallel Pro™, designed with increased capacity in mind but without forfeiting the control and precision required to produce the highest-quality oils.

“Our customers are working in a constantly changing market, where legislation, changing preferences, increasing adoption rates and newly opening markets impact demand and the bottom line every day,” said Wes Reynolds, CEO of Green Mill Supercritical.


“We developed the Parallel Pro with this challenge in mind by creating a machine that allows for increased capacity to scale as a manufacturer’s market grows, and pivot when it changes.”

Competitor designs that increase capacity through the cheap and easy approach of upsizing extraction components end up sacrificing precision, control and efficiency, according to Reynolds. The Parallel Pro provides maximum control over pressure, temperature and flow rate during supercritical CO₂ extractions, allowing customers to achieve the highest-quality oils. At the same time, the Parallel Pro enables producers to increase yields in roughly the same amount of time required for much smaller yields with other machines.

“Most companies increase throughput by building larger and larger components — extraction and collection vessels, pump, heat exchanger and more. You make everything bigger to increase production,” Reynolds said. “But when you do that, you require more time and electricity per pound of biomass processed. The Parallel Pro requires just a slightly larger footprint than our workhorse SFE Pro, but doubles all the things it does so well, at a very attractive price point.”

The Parallel Pro offers the following sought-after features:

  1. Doubling the throughput and flow rate of Green Mill Supercritical’s SFE Pro™ machine, at least 130 pounds per 24 hours
  2. A maximum pressure of 6,000 pounds per square inch (psi)
  3. A maximum flow rate of 1 kilogram per minute (measured with a mass flow meter)
  4. A Weekender Mode™ that can yield an additional four labor-free extractions every week
  5. 3D-printed heat exchanger that heats CO₂ directly, which boosts condition accuracy in the system
  6. The same automation, compact footprint, and extraction efficiency of the SFE Pro line of machines

The development process resulted in a machine that maintains the attention to detail that Green Mill Supercritical has become recognized for across the industry: A fit and finish featuring laboratory-grade equipment. And it is just the latest in a series of innovations currently in development as part of Green Mill’s core commitment to continuous improvement.

“We engineer and manufacture equipment, but more than that, we are a technology company,” Reynolds continued. “The CO₂ extraction equipment space has had challenges living up to some of the basic tenets of tech, including progress in making components smaller and more powerful. Bigger is not always better, and that’s a premise we try to live by.”
