Problems solved by technology
Independence of work cannot be guaranteed and energy is wasted
while liquid CO 2 Injected from the upper part of the extractor, to some extent restricts the cumulative contact area between the pulverized raw material and the extractant
Therefore, the extraction process is delayed and the production efficiency of the equipment is restricted

The inventive single-circuit continuously operating self-contained device for producing CO2-extracts from vegetable raw materials comprises at least two extractors (1, 2) and electric heaters (10) arranged in the lower part thereof, at least two evaporators (3, 4) provided with electric heaters (11) arranged therein. The upper part of the extractors (1, 2) and the evaporators (3, 4) are provided with inspection sensors for controlling the volume of liquid CO2. Said device also comprises a condenser (5) provided with a cooling unit (6), a storage capacity (7) and an additional capacity (8) for the liquid CO2 which are connected to each other in such a way that it is possible to continuously supply the CO2 to the circuit. The storage capacity (7) is connected to the condenser (5) and the extractors (1, 2). Filters (18) for cleaning extract, capacities (14, 17) for raw materials and extract, respectively and a pump (9) for supplying the liquid CO2 are technologically connected with the aid of pipelines provided with stop valves in such a way that they form a closed circuit. Each extractor (1, 2), each evaporator (3, 4) and the condenser (5) is provided with electronic instruments (12, 32) in order to inspect and control the temperature regime of the extraction process.
Description
technical field [0001] The present invention is a method for extracting plant raw materials using solvents, to be precise using liquid CO 2 Equipment for extracting substances from plant raw materials. Background technique [0002] Existing production uses liquid CO 2 The equipment for the extraction of substances is described in "Натуралъные пишевыеароматизаторы-CO 2 -экстракты "Касъянов Г.И., Пехов А.В., Таран А.А." Пищевая промышленностъ", 1978г., с.74. Published. [0003] This equipment requires at least two extractors, at least two evaporators, condensers, extractant containers, vacuum pump to evacuate the system, extract filter, oil solvent solution pump, regenerator, cold water tank, for water A closed circuit consisting of a heated heater, a continuous conduit required by the process, and closed fittings attached to the conduit. Use liquid CO 2 Equipment for extracting substances from plant raw materials. [0004] This limits the working mode of single or multi...
