Abstract

The invention relates to supercritical fluid extraction equipment which comprises a separator, a carbon dioxide storage tank, a condenser, an evaporator, a cold source heat pump unit and a supercritical carbon dioxide extraction system, wherein the cold source heat pump unit is connected with the condenser and the evaporator, the condenser is connected with the separator, the evaporator is connected with the carbon dioxide storage tank, and the supercritical carbon dioxide extraction system is connected with the separator and the carbon dioxide storage tank. According to the supercritical fluid extraction equipment provided by the embodiment of the invention, the supplying of cold energy and heat energy is not independently carried out any more; meanwhile, an extraction solvent, namely carbon dioxide, is introduced to be used as an energy transfer medium, the phase change capacity of the extraction solvent in the extraction process provides the cold energy and the heat energy for the self system, so that the extraction energy consumption is reduced by 23.6 percent in comparison with that of conventional equipment, the energy consumption can be greatly reduced during long-term production, and the problem of high operation cost of a supercritical carbon dioxide fluid extraction process is solved to a certain degree.

Description

technical field [0001] The invention relates to an extraction device, in particular to a supercritical fluid extraction device. Background technique [0002] At present, the extraction methods of natural products generally include steam distillation, solvent extraction and supercritical fluid extraction. Due to the high temperature and long time in the processing process, the steam distillation method will oxidize the active ingredients, resulting in a change in smell, and can only extract the essential oil part of the raw material, but cannot extract flavor components and functional components with higher economic value, such as ginger. Gingerol in gingerol, piperine in pepper, polibyllide in angelica, etc. have inherent disadvantages such as low extraction rate and poor economic benefit. The solvent method generally uses ethanol, methanol, acetone, petroleum ether and other aqueous organic solvents to replace and extract the active ingredients in the raw materials. Althou...
