Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical extraction devices, in particular to a L-parocalin extraction device. Background Art
[0002] There are two main methods for synthesizing L-parocalin: chemical synthesis and microbial fermentation. The chemical synthesis route primarily uses benzoic acid as the raw material and synthesizes L-parocalin through a multi-step reaction. This synthesis route has the advantages of mild reaction conditions and a wide range of applications, but it requires multiple reaction steps and the purity of the reaction product is difficult to control. The microbial fermentation synthesis route mainly utilizes microbial metabolism to synthesize L-parocalin. Currently, the microorganisms known to synthesize L-parocalin include actinomycetes and yeast. This synthesis route has the advantages of mild reaction conditions and high-purity reaction products, but it requires the selection of appropriate microorganisms and culture conditions. After the reaction is completed, the L-parocalin must be extracted using extraction equipment.
[0003] When the extract is transported into the extraction equipment, a filter is needed to filter the raw materials. However, after long-term use, a large amount of raw materials will remain on the filter wall, which is not easy to clean. The dirt remaining on the filter will contaminate the next extraction and reduce the quality of the extracted L-parocalorin.
[0004] To this end, we propose a L-parocalin extraction device. Summary of the Invention
