Supercritical Fluid Technologies has released a new supercritical extractor for processing natural foods
Newark, Del. – Supercritical Fluid Technologies (SFT) has introduced a new pilot scale supercritical extractor for processing natural products.
The company says the SFT-NPX-10 can perform supercritical fluid extractions in either single or dual 10-L sample vessels with single or dual separators. A Coriolis mass flow meter helps guarantee precise mass flow measurement. A pneumatic CO2 pump with an integral pre-chiller is used to maximize pumping efficiency. And a programmable controller is available as an upgrade for automated regulation of pressure, temperature and process cycles.
Using supercritical CO2 to perform extractions on botanicals, herbs, spices and other natural product materials has significant benefits over the use of traditional liquid solvents.
The supercritical fluid can add the benefits of high diffusivity and pressure tunable solvency power. Additionally, no residual solvents are in either the extract or remaining biomass, and there’s no need to perform a distillation step since upon dropping pressure the CO2 becomes a gas. The extracted material is pure and in its natural state. The CO2 may be safely vented or optionally recycled.
