Description

technical field [0001] The invention relates to the field of extraction devices, in particular to an extraction device with crushing and stirring functions. Background technique [0002] At present, tea polyphenols cannot be artificially synthesized and must be extracted from nature. Traditional tea polyphenol extraction methods mainly include solvent extraction and ion precipitation, but these methods will cause rapid oxidation of tea polyphenols during the extraction process, and The yield of extracted tea polyphenols is low, and more impurities affect the purity and quality of the product. The extraction of tea polyphenols by extraction can improve the extraction efficiency, reduce the production of impurities, and improve the purity of tea polyphenols. However, the raw materials need to be manually cleaned and crushed before extraction, which is cumbersome, time-consuming and labor-intensive. Phenol is sensitive to temperature, so strictly controlling the temperature du...
