METHOD AND DEVICE FOR OBTAINING AN EXTRACT FROM VARIOUS TYPES OF PLANT RAW MATERIALS BY THE ACTION OF PULSED ELECTRICAL DISCHARGES Russian patent published in 2022 - IPC B01J19/08 B01D11/00 B01D11/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of chemistry, namely to a device for obtaining an aqueous extract from the fruits or leaves of Japanese sophora or scorzonera root crops under the influence of pulsed electrical discharges at a certain pulse duration, discharge frequency, voltage amplitude. The device consists of a cylindrical extraction chamber made of polyethylene, with a lid, with electrodes, where high-voltage and grounded electrodes are made of food-grade stainless steel, and electrodes of the tip-plane type are used, the grounded electrode is made in the form of a sieve with a hole size of 1 mm and a hole density of 25 pcs/cm² and is located at a distance of 0.03 m from the bottom of the extraction chamber.

EFFECT: provides for the exclusion of over-grinding of raw materials, facilitating and reducing the filtration time of the extract, as a result of which its quality increases and the possibility of turbidity of the solution is excluded.
