BIOGAS UNIT Russian patent published in 2023 - IPC A01C3/00 C12M1/04 

FIELD: waste processing.

SUBSTANCE: invention is intended for anaerobic digestion of organic waste from agricultural production with the production of biogas and organic fertilizers. The plant comprises a sealed vertical cylindrical tank, a bubbling mixing device installed in the tank, a vertical mixer consisting of a central vertical shaft with horizontal blades. Inside the hollow central vertical shaft along its height, inductor coils are regularly located, the windings of which are connected to each other and slip rings rigidly fixed on the outer surface of the upper part of the central vertical shaft. The electrically conductive brushes of the sliding current collection unit are in contact with the slip rings, the terminals of the electrically conductive brushes are designed to be connected to an alternating voltage source. The sections of the central vertical shaft, in which the inductors are located, are equipped with horizontal blades made of an electrically conductive material, whereas the ends of the horizontal blades are rigidly attached to the bases, which are made of a material with a shape memory effect and are rigidly fixed on the side surfaces of the sections of the central vertical shaft, in which inductors are located.

EFFECT: installation provides a reduction in electricity consumption.
