Supercritical
Fluid Technologies (SFT) is pleased to introduce a new pilot scale
supercritical extractor for the processing of natural products. The SFT-NPX-10
is designed to simplify the extraction of a wide variety of natural products,
and to facilitate the transition from laboratory scale equipment to production
processing systems.
The SFT-NPX-10 is designed to perform supercritical fluid
extractions in either single or dual 10 Liter sample vessels with single or
dual separators, resulting in maximum efficiency. A Coriolis mass flow meter
guarantees precise mass flow measurement. A pneumatic CO2 pump with an integral
waterless pre-chiller (patent pending) is used to maximize pumping efficiency.
Upgrade to an RIO programmable automation controller for automated regulation
for 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. While the supercritical
fluid possesses many of the same characteristics of a liquid solvent, it adds
the benefits of high diffusivity and pressure tunable solvency power.
Additionally, no residual solvents are in either the extract or remaining
biomass. There is 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 for even
greater efficiency. Since the solvency power of the fluid is pressure
dependent, it is possible to “fractionate” to obtain multiple compositions from
a single raw material. This makes practical some separations that are difficult
or impossible to do with traditional liquid solvent and distillation processing.
