Abstract: The invention relates to a process and apparatus of extraction with the use of vacuum and can be used to extract the bioactive agents from raw materials. The method of extraction of materials, includes the heating the extractant, the preliminary extraction of raw materials with the heated rollers by means of extractant, the impregnation of raw material with extractant and extraction of raw materials in vacuum-impulsive mode by cycles, which include the heating with hot coolant gas not exceeding 39° C. and a creation of vacuum in the chamber in the regime of quick vacuum-impulsive exposure with stepwise multiple pressure drop from the atmospheric pressure to the pressure not more 0.0001 MPa, followed by keeping under vacuum to stabilize the temperature of the mixture and the vacuum relief at the end of the cycle. The distilled water, or organic solvents or mixtures thereof are used as the extractants.

Abstract: The invention can be used for extraction of valuable biologically active agents from 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 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. 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.

Abstract: 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.

Abstract: The invention relates to method and device for drying materials of plant and animal origin. The method includes heating a material to a temperature that does not cause denaturation of the original properties thereof, high-speed pulse vacuuming, maintaining the vacuum tor a period of time, and relieving the vacuum until atmospheric pressure is reached. The material is heated in a drying chamber and the vacuum is relieved using a dried air or gas heat earner with a temperature of up to 300° C. A device comprises two drying chambers with hermetically sealing doors, which are connected by pipes haying fast-acting valves to a receiver tank, heat exchangers and condensate receivers, a vacuum pump and a device for heating and delivering a heat carrier, which is situated in a separate thermally insulated chamber and is connected to the inlet of each drying chamber by means of thermally insulated air delivery conduits with valves.
