Problems solved by technology

[0004] However, during the crushing process of the plant, part of the essential oil will be volatilized, and it is difficult to collect the volatilized plant essential oil, which makes the plant waste part of the essential oil during the crushing process. Therefore, if the more expensive plant essential oil is produced A lot of waste will greatly increase the extraction cost of plant essential oils, which is not conducive to the development of the industry; moreover, the extraction process of plant essential oils is cumbersome, and the efficiency of extraction and the effect after extraction will be reduced

Abstract

The invention relates to the technical field of separation equipment, in particular to a plant essential oil supercritical extraction system which comprises an extraction barrel and supporting legs. A liquid inlet, a liquid outlet and a material outlet are formed in the extraction cylinder; the supporting legs are fixedly connected to the side wall of the extraction cylinder; the extraction cylinder can be used for extracting plant essential oil from plants through the impact of carbon dioxide fluid; the partition plate is in sliding sealing connection with the extraction cylinder, and one end of the partition plate is fixedly connected with a push-pull rod; according to the plant essential oil extraction device, high-speed impact of carbon dioxide fluid in a high-pressure state on plants in the extraction barrel in a normal pressure state is controlled, so that the plants are effectively crushed in the extraction barrel, and then extraction of plant essential oil is realized by utilizing the characteristic that the carbon dioxide fluid can react with the plants; the plant essential oil is prevented from volatilizing when plants are broken, so that unnecessary waste is avoided, meanwhile, the extraction steps are reduced, the working time is saved, and the extraction efficiency of the plant essential oil is improved.

Description

technical field [0001] The invention relates to the technical field of separation equipment, in particular to a plant essential oil supercritical extraction system. Background technique [0002] Plant essential oils are the unique aromatic substances extracted from plants, which are extracted from the flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbal plants, and are extracted by distillation and pressing; supercritical fluid extraction is the use of supercritical Fluid, that is, a fluid in a thermodynamic state with a temperature higher than the critical temperature and a pressure higher than the critical pressure, is used as an extraction agent to extract a specific component from a liquid or solid to achieve the purpose of separation. [0003] When plant essential oils are subjected to supercritical extraction, carbon dioxide fluid generated by high-pressure and low-temperature forms is generally selected as supercritical gas, and the crushed plants are p...
