Solvent free

CO2 Supercritical Fluid Extraction Equipment

Solvent-free extraction with food-grade CO2. One extractor, two separators, 50MPa design pressure, recycled CO2.

Supercritical CO2 extraction uses carbon dioxide held above its critical point as the solvent. In that state CO2 behaves like a liquid dense enough to dissolve resins, waxes and volatile oils, yet it still diffuses through the plant bed like a gas. When the pressure is released in the separator the CO2 turns back into gas and leaves the extract behind, so the finished oil carries no residual solvent and no solvent recovery step is needed downstream.

Who This Equipment Is For

  • Hemp and botanical processors who need a residual-solvent-free crude oil
  • Essential oil and fragrance houses extracting heat-sensitive aromatics such as cinnamon and neem
  • Nutraceutical and cosmetic manufacturers working to pharmaceutical housekeeping standards
  • Research groups and universities running extraction trials before scaling up

Problems It Solves

  • Residual solvent in the finished extract and the testing burden that comes with it
  • Thermal damage to terpenes and other volatile fractions during extraction
  • Fire and ventilation restrictions that rule out flammable solvents on site
  • Extract colour and wax load that make downstream refining expensive

Key Benefits

No solvent residue

CO2 leaves the extract as a gas in the separator, so there is nothing to purge or test for.

Gentle on volatiles

Extraction runs from ambient temperature up to 85°C, protecting aroma fractions.

CO2 is recycled

The CO2 circulates in a closed loop instead of being consumed batch by batch.

Tunable selectivity

Pressure and temperature can be tuned per material, and an additive can be dosed into the supercritical fluid.

FAQ

Questions About CO2 Supercritical Extraction

Can the CO2 be reused?
Yes. CO2 is used in circulation inside the system rather than consumed on every batch.
What materials can be processed on a CO2 extraction machine?
The CO2 extraction machines are used for hemp oil, wheat embryo oil, fish oil, tobacco essential oil, Arteannuin, Sundrops oil, Gingerol, Pepper haematochrome, Hops extract and Agarwood oil, among others.
What size machines are available?
Machines from 0.5L to 200L are supplied. Larger capacities can be customised against your process requirement.
How are the pressure vessels designed?
Pressure vessels are designed to the related national standard and rule demand, with an overpressure protection system, which means sufficient safety valves.
How long does production take?
The process flow of a supercritical CO2 extraction machine is complex. Production generally takes about 60 workdays, because every procedure and detail is inspected before the machine leaves the workshop.
