Estimating the term…
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.
The method for extraction of materials comprising heating of the extracting agent, vacuum-impulsive impregnation of raw materials with the extracting agent and extraction of raw materials in thermo-vacuum-impulsive mode at temperature ranges of components and mixtures, not leading to denaturation of raw materials and final product, characterized in that before vacuum-impulsive impregnation the raw materials are preliminary extracted by means of heated rolls with the extracting agent at extracting ratio (extracting agent:raw materials) not more than 2, the extracting agent is either distilled water or watered alcohol of concentration not less than 20%, and the obtained extract, as a result of thermo-vacuum-impulsive extraction procedure, has undergone a vacuum-impulsive filtration.
The device for extraction of material comprising extractor, connected with a reflux condenser, an extracting agent vessel and an accumulating vessel for extract with pipeline with valves interconnected and linked to a receiver, which is connected to a vacuum pump, characterized by the fact that at the inlet of the extractor, the device is equipped with a consecutively installed screw dozer connected through an intermediate vessel to the extracting agent vessel and constantly heated rolls which are equipped with a receiving net container to collect press cake impregnated with the extracting agent as well as two vacuum filters, connected consequently with the extracting agent vessel.
