Background
The conjugated unsaturated fatty acid has many special health care functions on human physiological activities, such as resisting canceration, promoting growth, reducing blood fat, reducing fat accumulation and the like. The supercritical carbon dioxide extraction method can extract oil at relatively low temperature, so that the unsaturated fatty acid in the rosa roxburghii tratt is prevented from oxidative deterioration, and the product of the rosa roxburghii tratt is not polluted, wherein the change of the carbon dioxide gas flow has two effects on SC-carbon dioxide gas extraction. On one hand, the flow of the carbon dioxide gas is increased, so that the mass transfer driving force in the extraction process can be increased, and the mass transfer coefficient is correspondingly increased, so that the mass transfer speed is accelerated, and the equilibrium solubility is quickly reached, thereby improving the extraction capacity and shortening the extraction time; on the other hand, too large flow of carbon dioxide gas will increase the flow rate of carbon dioxide gas in the extractor, and shorten the retention time of carbon dioxide gas, thereby reducing the contact time of carbon dioxide gas and the extract, not being beneficial to the improvement of extraction rate and increasing production cost. Therefore, there is an optimum value of the carbon dioxide gas flow rate in the extraction, but in practice, the carbon dioxide gas flow rate and pressure are not easily controlled in operation, and a supercritical carbon dioxide-based fatty acid extractor that can accurately control the carbon dioxide gas flow rate has been proposed.
