Zusammenfassung: | The invention can be used for extraction of valuable biologically active agents from vegetable, animal, fish, seafood, and other raw materials. The method of extraction comprises treating the raw materials by preliminary extraction with the extracting agent heated to the temperature not allowing denaturation of raw materials and the final product. The extracting agent is either distilled water or watered alcohol of concentration not less than 20% and ratio not more than 2, to carry out both the impregnation of raw material with the extracting agent and extraction in vacuum-impulsive mode in the extractor, to carry out catching of extract essential oils followed by condensation in dedicated condensers. The device for extraction comprises a screw dozer and continuous heated rolls with a vessel to receive press cake impregnated with the extracting agent, two parallel extractors, pipelines connected to a reflux condenser, a foam-destroying device, and vessels to store and prepare the extracting agent and the extract interconnected filters and condensers, additionally connected with a receiver which is equipped with a vacuum pump and pipelines. |
