What are the characteristics of supercritical CO2 extraction equipment?

Author:


The characteristics of supercritical CO2 extraction equipment determine its wide application range. In the pharmaceutical industry, it can be used for the extraction of effective ingredients from Chinese herbal medicine, the refinement of heat sensitive biological products and drugs, and the separation of lipid mixtures; In the food industry, the extraction of hops and pigments; In the spice industry, the refinement of natural and synthetic spices; Separation of mixtures in the chemical industry, etc.

The characteristics of supercritical CO2 extraction equipment determine its wide range of applications. For example, in the pharmaceutical industry, it can be used for the extraction of active ingredients of drugs, the refining of heat-sensitive biological products, and the separation of lipid mixtures; In the food industry, the extraction of hops, the extraction of pigments, etc.; In the fragrance industry, the refining of natural and synthetic fragrances; separation of mixtures in the chemical industry, etc.

Supercritical CO2 extraction equipment

(2) Supercritical CO35 extraction equipment can be extracted at close to room temperature (40~2 °C) and CO<> gas shrouded, effectively preventing the oxidation and escape of heat-sensitive substances. Therefore, the active ingredients of medicinal plants are maintained in the extract, and the substances with high boiling point, low volatility and easy pyrolysis can be extracted at temperatures far below their boiling point;

 

(2) The use of supercritical CO100 extraction equipment is the cleanest extraction method, because the whole process does not use organic solvents, so the extract has absolutely no residual solvent substances, thereby preventing the existence of harmful substances to the human body and environmental pollution during the extraction process, ensuring <>% naturalness;

 

(2) Extraction and separation are combined into one, when the saturated dissolved CO2 fluid enters the separator, due to the drop in pressure or temperature change, the CO<> and the extract quickly become two phases (gas-liquid separation) and immediately separate, not only the extraction efficiency is high and the energy consumption is less, the production efficiency is improved and the cost is reduced;

 

(2) CO<> is an inactive gas, no chemical reaction occurs during the extraction process, and it is a non-combustible gas, tasteless, odorless, non-toxic, and very safe;

 

(2) CO<> gas is cheap, high purity, easy to prepare, and can be reused in production, thereby effectively reducing the cost;

 

(6) Pressure and temperature can be used as parameters to adjust the extraction process, and the purpose of extraction can be achieved by changing the temperature and pressure, and the pressure fixation can also separate the substance by changing the temperature; On the contrary, the temperature is fixed and the extract is separated by reducing the pressure, so the process is simple and easy to master, and the extraction speed is fast.
