VERTICAL PILLAR-TYPE GRAIN AERATOR Russian patent published in 2022 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and is intended for ventilation of grain materials, and can also be used for ventilation of the harvest of various agricultural crops. The aerator includes a pillar in the upper part of which a fan is installed. The pillar is supported by an air supply cone connected to the perforated part of the pillar, made in the form of platelike rings. Platelike rings have a larger base and a smaller base. The platelike rings are installed with a gap relative to each other and face up with a smaller base. The gap between the rings is smaller than the smaller diameter of the rings and larger than the total thickness of several elementary layers of grains.

EFFECT: reduction in energy consumption, an increase in functionality and ergonomics when ventilating grain with vertical pillars due to the introduction of air into the grain mass using non-latticed perforated devices.
