Plant extraction equipment for large-scale continuous production

Abstract

The invention provides plant extraction equipment for large-scale continuous production. The plant extraction equipment comprises a main body Soxhlet extraction device, a feeding device arranged on a main body, a tail gas recycling device and a slag discharging device, wherein the feeding device is mounted at the top of the main body; the tail gas recycling device is mounted at the upper part of the main body; the slag discharging device is mounted at the upper part of the main body. The plant extraction equipment disclosed by the invention can automatically carry out immersion, permeation, siphoning, backflow and concentration differential pressure change according to a Soxhlet extraction principle to complete extraction of effective components of plants; the operation control is easy, and the operation is convenient; the equipment is reasonable and compact in structure and can realize the Soxhlet extraction principle and fulfill large-scale production; the requirement on extraction of effective components of most plants can be met; meanwhile, the potential safety hazard can be eliminated, and the environment pollution is alleviated.

Description

technical field [0001] The invention relates to a plant extraction equipment, in particular to a large-scale continuous production plant extraction equipment based on Soxhlet extraction. Background technique [0002] With the demand for medicine and health care products worldwide, plant extraction occupies an increasingly important position, and the requirements for the type and quality of extraction are also getting higher and higher. Although the extraction equipment has improved a lot in recent years, it is basically still a single Tank extraction is the main method, and the pipeline is changed in series to form reflux, countercurrent, etc., but it still cannot achieve the purpose of easy operation and double production capacity. The production environment pollution is still relatively serious, especially in the slag discharge process, and there are safety accidents. more hidden dangers. [0003] Although other equipment such as continuous dynamic, microwave, ultrasonic,...

Problems solved by technology

[0002] With the demand for medicine and health care products worldwide, plant extraction occupies an increasingly important position, and the requirements for the type and quality of extraction are also getting higher and higher. Although the extraction equipment has improved a lot in recent years, it is basically still a single Tank extraction is the main method, and the pipeline is changed in series to form reflux, countercurrent, etc., but it still cannot achieve the purpose of easy operation and double production capacity. The production environment pollution is still relatively serious, especially in the slag discharge process, and there are safety accidents. more hidden dangers

[0003] Although other equipment such as continuous dynamic, microwave, ultrasonic, subcritical, and supercritical extraction forms are also used, they have their limitations and safety issues. Not only the equipment investment is huge, but the operation method is complicated, especially the equipment is under pressure. production, especially in high-pressure operation, there are serious hidden dangers in production safety

[0004] Although oil extraction equipment can achieve large-scale production, it is not suitable for plant extraction. This is related to the molecular structure characteristics of plant active ingredients, which may easily cause blockage and incomplete extraction.

[0005] Soxhlet extraction is an ancient invented physical extraction method, which has the advantages of simple operation, safety and complete extraction. The Soxhlet extractor is used as the standard testing equipment in the national pharmacopoeia and laboratory testing, but due to the structure of the equipment, it is only widely used. In the extraction equipment in the laboratory, there is no equipment that can be used in actual industrial production
