DEVICE FOR GAS-LIQUID EXTRACTION Russian patent published in 1994 - IPC

Abstract RU 2021836 C1

FIELD: extraction of herbi raw materials by liquified gases in food processing industry, medicine, and perfume production. SUBSTANCE: device has a mixer for production of herbi raw material suspension in a solvent. It also has an extractor, evaporator and condenser constituting a closed circuit and liquified gas source connected to the extractor, and a source of organic solvent connected to the mixer. Such a structure allows one to prepare the suspension in the mixer at atmospheric pressure to simplify loading of dry herbi raw materials in the mixer and increase yield of extractive substances at the expense of use of combined extracting agent. EFFECT: higher efficiency. 6 cl, 1 dwg
