A Superior and Economical World Class Technology for Quality Natural Products

The current global trends show a growing preference for products from natural sources. Also there is an increasing concern for safe, eco – friendly and pollution free manufacturing processes. SCFE technology provides a ready and total solution to these challenges. Its superiority over the conventional technologies of extraction, especially for natural products in the food and pharmaceutical industry is well recognized.

SCFE is a two step process which uses a dense gas as a solvent e.g., Carbon Di Oxide (CO2) for Extraction, above its critical Temperature (31O C) and critical pressure (74 bar). The feed generally ground solid is charged into the extractor. Supercritical CO2 is fed to the extractor through a high pressure pump (100 – 500 bar). The extract laden CO2 is sent to a Separator (60 – 120 bar) via a pressure reduction valve. At reduced temperature and pressure conditions, the extract precipitates out in the Separator. The Extract Free CO2 stream, leaving the separator is then recycled to the extractor.
