Products Description

subcritical co2 extraction equipment is the state in which the solvent is in the temperature interval above its boiling point but below the critical temperature, and exists in a liquefied state under a certain pressure. This technique is based on the principle of similar solubility of organic substances, through the process of molecular diffusion between the extracted material and the extractant in the immersion process.

The process principle of subcritical extraction is based on the use of liquefied subcritical solvents to extract the material countercurrently under a certain pressure. During the extraction process, the solvent is vaporised in the extractant (liquid phase) by an evaporation process, which separates it from the extracted target components to obtain the product. Another product (solid phase) is obtained when the extracted material is evaporated to remove the adsorbed solvent. The vaporised solvent is liquefied after compression and heat exchange and recycled.

subcritical co2 extraction equipment techniques offer a variety of advantages including, but not limited to, high efficiency, energy efficiency, and environmental friendliness. For example, the modification and functional expansion of the multi-channel recoverable pilot subcritical fluid extraction device achieves effective recycling of extraction solvents with an average recovery rate of around 93%, thus saving energy and reducing emissions. In addition, subcritical extraction technology compared with CO2 supercritical extraction technology, the choice of solvents to expand the range.

Subcritical solvent extractor has a wide range of applications, and can be used for the extraction and purification of a variety of products such as natural plants, biological, food, and so on. For example, the use of HFC-134a as a solvent carrier for extraction can effectively extract natural plants, biological, food, and many other products. In addition, subcritical extraction techniques can be used in combination with other techniques, such as molecular distillation, to improve extraction rates and purity.
