INSTALLATION FOR EXTRACTION OF PLANT RAW MATERIALS Russian patent published in 2019 - IPC B01D11/02 C11B1/10 C11B9/02 

FIELD: technological processes.

SUBSTANCE: invention relates to equipment for the extraction of plant materials and can be used in the food, pharmaceutical and cosmetic industries. Installation for the extraction of plant materials includes an extraction chamber, made in the form of a cylindrical body with a lid, with interchangeable screens installed in its lower part, having openings in the upper and lower parts. Extraction chamber is connected in series with a refrigerator having steam and coolant inlet pipes and condensate and coolant outlet pipes, and with the florentine device, which has the condensate inlet, the light fraction, and the florentine liquid, connected to the extraction chamber, forming a closed loop. Installation further comprises an ejector pump with discharge and suction nozzles, a liquid pump, a vacuum pump, a throttling device, a mold with an extractant input nozzle and a steam output nozzle. Extraction chamber additionally has a steam outlet pipe located under the screens. Refrigerator and the florentine device are made in a single package, while the florentine device has an inclined partition that divides it into the condensate reception area and the separation zone. Receiving zone of the florentine device condensate is communicated through a vacuum pump with the suction nozzle of an ejector pump. Florentine liquid outlet pipe communicates through a liquid pump with a refrigerant inlet pipe, the refrigerant outlet pipe communicates with openings in the upper and lower parts of the extraction chamber and is located at the level of the vapor outlet pipe from the extraction chamber. Mold is communicated with the hole in the lower part of the extraction chamber through the input pipe of the extract, and the pipe output of steam from the mold communicates with a vacuum pump. Pipe for discharging condensate from the refrigerator is connected to a throttling device and through the condensate inlet pipe of the florentine device communicates with the florentine device separation zone, and the light fraction outlet pipe from the florentine device is located above the level of the condensate inlet pipe. Nozzle of the output of florentine liquid is located at the level of the nozzle entering the condensate into the florentine device.

EFFECT: invention allows to obtain temperature-sensitive valuable components of plant materials, as well as to reduce energy consumption through the use of spent refrigerant that does not require additional heating as an extractant.
