CONE DRYER Russian patent published in 2022 - IPC F26B11/04 

FIELD: forestry machinery.

SUBSTANCE: technical solution relates to forestry machinery, in particular to devices for drying cones of coniferous trees in order to extract seeds from them. The cone dryer includes a heat-insulated chamber in the form of a cabinet with doors, an electric heat carrier heater with automatic temperature control, a device for supplying the heat carrier to the drying zone, and a heat carrier distributor, and a container for cones. The device for supplying heat carrier to the drying zone is made in the form of a centrifugal fan. The coolant distributor is made in the form of a horizontally installed perforated pipe, equipped with installed radially perforated branch pipes, the inner cavity of which communicates with the inner cavity of the perforated pipe. The capacity for cones is made in the form of a mesh drum, equipped with removable flaps and installed in a heat-insulated chamber with the possibility of rotation around the perforated pipe and changing the rotation speed. The heat-insulated chamber is mounted on racks. Doors are installed both in the upper and lower parts of the heat-insulated chamber. The centrifugal fan drive is made with adjustable speed. In the upper part of the sides of the heat-insulated chamber, outlet pipes are installed.

EFFECT: energy intensity of the drying process is reduced, the quality of drying of cones is increased with a simpler design of the cone dryer.
