Description

Technical Field

[0001] This utility model relates to the field of plant essential oil extraction technology, specifically to a peony essential oil extraction and filtration device, which improves the extraction efficiency and purity of peony essential oil and is suitable for large-scale production. Background Technology

[0002] Peony essential oil is rich in various active ingredients and has high medicinal and skincare value. Its extraction process requires steps such as raw material crushing, solvent extraction, and impurity filtration. In existing technologies, peony essential oil extraction often uses a single device in a step-by-step operation: the stirring device is only used to mix the raw material and the extractant, and the mixture needs to be manually transferred to the filtration device, which is not only inefficient but also prone to essential oil volatilization or contamination during the transfer process; traditional transfer pumps (such as centrifugal pumps) are prone to clogging when transporting mixtures containing solid impurities and may damage the essential oil components due to shear force; the filtration equipment is mostly single-stage filtration, which is difficult to effectively remove fine impurities (such as petal fibers and colloidal particles), affecting the purity of the essential oil. Therefore, a peony essential oil extraction and filtration device is proposed. Utility Model Content

[0003] In view of this, the present invention provides a peony essential oil extraction and filtration device, which aims to solve one of the technical problems in the existing peony essential oil extraction process, such as dispersed equipment, cumbersome operation, easy blockage of conveying, and low filtration purity.
