Technical principle analysis of supercritical extraction equipment!

Technical principle analysis of supercritical extraction equipment!

Supercritical fluid is a kind of supercritical fluid, which is neither gaseous nor liquid state between gas and liquid. This kind of material can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is larger, similar to that of liquid, and its viscosity is closer to that of gas. So supercritical fluid is an ideal extractant.

What environmental applications are suitable for supercritical CO2 extraction equipment?

What environmental applications are suitable for supercritical CO2 extraction equipment?

Subcritical, similar to supercritical extraction, refers to the state conditions under which substances exist. It refers to substances that exist as fluids at temperatures above their boiling point but below their critical temperature and at pressures below their critical pressure. When the temperature does not exceed a certain value, pressurization of the gas can make Liquefaction of gases liquefied. Above this temperature, no matter how much pressure is added, Liquefaction of gases cannot be liquefied. This temperature is called the critical temperature of the gas. At critical temperature, the pressure necessary for Liquefaction of gases is called critical pressure.

Basic Applications of Supercritical Extraction Equipment!

Basic Applications of Supercritical Extraction Equipment!

Supercritical extraction equipment can extract and purify many products such as biology, food, medicine, etc. The principle of supercritical extraction equipment: make use of the influence of CO2 pressure and temperature on the solubility of supercritical fluid to make it have a good dissolution effect on Natural product. In the extraction kettle, quickly dissolve the special solvent supercritical fluid and solute, so that after the completion of extraction (solid or liquid), it can directly enter the separation kettle. Due to the change of pressure and temperature conditions, the fluid can be gasified, and the dissolved substances can be resolved to achieve the purpose of separation.

Characteristics and Development of Supercritical Extraction Equipment!

Characteristics and Development of Supercritical Extraction Equipment!

The traditional separation method of Natural product has low purity, complicated process and unsatisfactory extraction rate; Technological means such as water vapor distillation and solvent extraction often cause some heat sensitive or chemical unstable components in Natural product to be destroyed during processing, thus changing the unique flavor and nutrition of natural foods. Moreover, the pollution of solvent residues during processing is unavoidable. Supercritical extraction technology can well remedy the defects of traditional processes due to the following characteristics.

The basic principle of Supercritical fluid extraction process!

The basic principle of Supercritical fluid extraction process!

Supercritical fluid extraction is a new extraction and separation technology. It uses supercritical fluid, that is, the fluid in the Thermodynamic state where the temperature is higher than the critical temperature and the pressure is higher than the critical pressure, as the extractant. Extract specific components from liquids or solids for separation purposes.
