Ethanol Extraction


Extracting oils from cannabis and hemp is not an easy process. It often involves a very labour-intensive procedure, many different types of equipment and compliance with European regulations which can be quite baffling. Spectrum Technology has recognised these issues and put its 20+ years of engineering and manufacturing experience into the cannabis industry to provide equipment for the entire process, eliminating these issues.

Spectrum Technology provides top of the line Cryogenic Ethanol Extraction equipment for small to large industrial-scale operations. Whether you are processing 20kg per day or looking at building an industrial turnkey extraction facility, Spectrum has you covered.

Designed and manufactured in Canada, by our partner Evolved Extraction, our EV-M turnkey extraction solution is a batch centrifugal separator targeting botanical, hemp and cannabis oils using cryogenic ethanol extraction at -40C.

The EV-M extractor is a closed-loop system capable of up to three runs per solvent batch per hour, when utilising ethanol as the primary extraction solvent. It comes pre-plumbed for chillers and heaters, and also includes nylon mesh filter bags to make loading and unloading labour efficient. From a single centrifugal unit processing up to 14-40kg/hour, these units are perfect for starting out your Cannabis Extraction Facility. A single operator can easily program custom cycle parameters to process up to 272kg of biomass in a 10 hour shift, or run multiple units in parallel to scale up throughput.

Our EV-M Solution provides:

  • Processing Efficiency, with a single, Standard solution providing 272 kg of daily throughput under typical conditions*
  • Scalability, including a modular solution design and serial integration capabilities to support cost-effective growth of processing operations
  • Processing Intelligence, including reporting on all processing activities via data logging and on-board analytics

*Based on a single Centrifugal Separator in continuous operation for one 10-hour shift.

EVM Additional Features:

  • Capacity: Up to 30 lbs/batch
  • Batch cycle time: 20-30 min*(dependent on customer SOP, mill size, THC/CBD content, and desired temperature)
  • Designed, engineered & manufactured in Canada
  • Power requirements: 240VAC 15A circuit (Haz-Loc requirements considered)
  • Centrifuge rated for C1D2 Hazardous locations
  • Third party engineered peer-reviewed by PSI
  • 7″ high resolution touch screen HMI (human machine interface). Designed for ease of use and optimization in process control
  • Full statistical analysis allowing the user to view and log: batch time, average batch time, and display live outputs (RPM, G-force, inside temps, shift cycles, lifetime cycles, etc.)

Automation & Integration

The EV-M Ethanol Extraction equipment can also be easily integrated with our other technologies, such as our oil and solvent recovery options (OERS) for 99%+ ethanol recovery, decarboxylation, and ethanol reproofing. We can also work with any other equipment in your facility, allowing you to streamline and automate your entire production process. Together, these technologies can create a completely automated, GMP turnkey solution for your cryogenic ethanol extracting needs.
