Supercritical  Co2 Extraction Equipment

Supercritical Co2 Extraction Equipment


The supercritical co2 extraction and separation process is a process in which supercritical carbon dioxide is used to produce special dissolution of some special natural products, and the solubility and density of supercritical carbon dioxide are used for extraction and separation.


The principle of supercritical extraction equipment is to contact the supercritical carbon dioxide with the substance to be separated in the supercritical state, so that it can selectively extract the components with different polarity, boiling point and molecular weight in sequence. Of course, it is impossible to obtain a single extract corresponding to each pressure range, but the conditions can be controlled to obtain the best ratio of the mixed components, and then the supercritical fluid can be turned into an ordinary gas by means of decompression and temperature increase, and the extracted substance is It is completely or substantially precipitated to achieve the purpose of separation and purification.


Supercritical extraction devices can be divided into two types. One is the research and analysis type, which is mainly used for the analysis of small amounts of substances or to provide data for production. The second is the preparation and production type, which is mainly used in batch or mass production.


Supercritical co2 extraction can be used for the extraction and separation of sea buckthorn oil, the decaffeination of coffee beans, the decaffeination of tobacco, the extraction of coffee flavors, the extraction of useful components in hops, and the extraction of high-purity star oil vine oil from Soybean oil and egg yolk extracted from soybeans to remove cholesterol, etc.


The supercritical extraction device can be roughly divided into eight parts in terms of function: extractant supply system, low temperature system, high pressure system, extraction system, separation system, modifier supply system, circulation system and control system. Specifically, it includes equipment such as carbon dioxide injection pumps, extractors, separators, compressors, carbon dioxide storage tanks, and chillers. Since the extraction process is carried out under high pressure, the pressure resistance performance of the equipment and the entire pipeline system is relatively high.


In the production process of this equipment, our company has realized the automatic monitoring of the computer, which greatly improves the safety and reliability of the system and reduces the operating cost.
