SCFE Production Technology

Layer-27.png

Supercritical Fluid Extraction of solids, is generally operated in batch mode on milled materials (or pellets, granulates), with food grade carbon dioxide as solvent. The equipment consists of two or more extractors operating above the CO2 critical pressure, and two separators where the extract and the CO2 are separated prior to the CO2 being recycled.

The supercritical CO2 extraction process consists of first raising the temperature and pressure of the carbon dioxide gas till it reaches super critical state. This is done using a high pressure pump and a heater. The organic raw material is loaded into the extractors through which the super critical CO2 passes. Based on the components present in the raw materials, and the pressure-temperature settings, the supercritical CO2 extracts the oils from the raw materials and passes through a series of pressure regulator valves to enter the separators. The two separator pressures are controlled individually to separate the different components of the extract. Once the extracted oil is separated from the CO2 which escapes in the form of a gas, the oil is collected in collection vessels while the extract free Carbon dioxide is recycled by condensing and storing in the CO2 tank in the liquid form. This CO2 is then reused and the entire cycle is repeated for the duration of the batch.

At the core of Esencial® production processes stands the avant-garde and environmentally friendly Supercritical Fluid Extraction Technology.Supercritical Fluid Extraction Technology is an innovative approach to producing raw material from Medicinal-Aromatic plants that is dense in plants’ natural components and active principles with innumerous health benefits.CO2 in liquid (supercritical) state serves as the ideal solvent for plants’ natural components, gently pulling them away from plant’s stem, leaf and flowers while keeping the integrity of these molecules intact, leaving behind no traces.This outstanding quality makes CO2 Total Extracts a powerful raw material for many other industries, such as: Pharmaceutical, Cosmeceutical, Nutraceutical, Chemical, Food Industry etc.Esencial® takes great pride in referring to Nature as its only supplier.
