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 method of timber drying including the blowing of timber with heating medium operation at atmospheric pressure and heating the timber to average volume temperature 80-100° C., impulsive (quick) vacuum treatment operation at pressure not more than 50 mm Hg during time not more than 10 s with pressing-out of free moisture from timber without water to vapour transition to reach stable constant value of limber temperature, vacuum relief to atmospheric pressure using heat recuperating air with temperature 150-300° C., and at manometer pressure not more than 0.07 MPa. The apparatus for timber drying comprises two drying chambers connected through pipelines with quick-response valves to cooled receiver, which is placed in series to the second one and connected to vacuum pump through pipeline with vacuum lock. The first receiver is equipped with spiral-shaped guide devices for vapour-and-drop flow direction, which are installed at a tangent to inner diameter of receiver body.
