CONE DRIER Russian patent published in 2022 - IPC F26B9/06 

FIELD: forestry technology.

SUBSTANCE: invention relates to forestry technology, in particular to devices for drying cones of coniferous trees in order to extract seeds from cones. The cone drier includes a heat-insulated chamber in the form of a cabinet with a door, a multi-tiered rack with shelves for drying boxes, electric coolant heaters with automatic temperature control, a device for supplying coolant to the drying zone, a coolant distributor. Drying boxes are made in the form of hollow rectangular parallelepipeds with one end side open and a perforated upper part. Inside the second bottom and subsequent drying boxes, vertically staggered bushings with through holes connecting their upper and lower parts are installed. The device for supplying coolant to the drying zone is made in the form of a fan, the coolant distributor is made in the form of a system of air ducts connecting to the open end sides of the drying boxes. Electric heaters of the coolant are installed in each air duct. Bushings on adjacent drying boxes are installed with a uniform offset relative to each other.

EFFECT: as a result, energy costs for drying cones are reduced and the design is simplified.
