HB221-40-180 Supercritical CO2 Extraction Machine

Supercritical extraction technology is the latest discipline emerging in modern industrial separation, and it is one of the internationally emerging advanced separation processes.

The so-called supercritical fluid means that the thermodynamic state is above the critical point (Pc, Tc). The critical point is the state point where the gas-liquid interface has just disappeared. The supercritical fluid has very unique physicochemical properties, its density is close to liquid, viscosity is close to gas, and the diffusion coefficient is large, the viscosity is small.

The characteristics such as large dielectric constant make it a better separation effect and a good solvent.

Supercritical extraction is under high pressure, at a suitable temperature, the solvent is contacted with the extract in the extraction kettle, the solute diffuses into the solvent, and then in the separator change the operating conditions to precipitate dissolved substances to achieve the purpose of separation.

FEATURE

Since the supercritical device has chosen CO2 medium as the supercritical extraction agent, it has the following characteristics:

Wide operating range, easy to adjust.
With good selectivity, the required components can be extracted in a targeted manner by controlling the pressure and temperature.
The operating temperature is low, and the extraction is carried out near room temperature, which is particularly suitable for heat-sensitive components.
During the extraction process, the possibility of oxidation in the presence of oxygen and light reaction is excluded, and the extract can maintain its natural flavor.
One step from extraction to separation is completed, and the CO2 after extraction does not remain on the extract.
CO2 is non-toxic, odorless, non-flammable, inexpensive and easily available, and can be recycled.
Fast extraction speed.
