Description

Technical Field

[0001] This utility model relates to the field of low-temperature extraction technology, and in particular to a low-temperature extraction device for plant active ingredients. Background Technology

[0002] The plant active ingredient low-temperature extraction device is based on a low-temperature environment and combines solvent extraction, supercritical fluid and other technologies to efficiently separate active ingredients at low temperatures. Through temperature control and pressure regulation systems, it reduces the oxidation and degradation of ingredients and is widely used in the fields of medicine and food. It solves the problem of low activity retention rate in traditional processes and promotes the effective extraction of effective ingredients from natural products.

[0003] The plant raw materials are first pre-treated, crushed and then mixed with pre-cooled solvent in a certain proportion and introduced into the extraction chamber. The mixture is stirred and extracted at low temperature. After extraction, the mixture enters the separation chamber, where it is centrifuged and filtered to separate the residue and extract. The extract is then distilled to recover the solvent, concentrated and stored at low temperature. Temperature control is required throughout the process to prevent component degradation, while balancing efficiency and purity.

[0004] In existing technologies, some low-temperature extraction devices for plant active ingredients require stirring different plants and filtering the extracted filtrate during operation. This necessitates the replacement of filter screens and stirring blades, which is cumbersome and prolongs downtime, reduces production continuity, lacks flexibility in adapting to different materials, and is prone to uneven extraction due to incompatible tools. Cleaning and maintenance are time-consuming, and residual impurities can contaminate subsequent batches. Furthermore, the replacement process can cause fluctuations in the low-temperature environment, increasing the risk of degradation of active ingredients. The complexity of operation may also increase safety hazards. Therefore, a low-temperature extraction device for plant active ingredients is proposed to solve the above problems.
