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, 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. The container for cones is made in the form of a mesh drum, equipped with removable shutters and installed in a heat-insulated chamber both with the possibility of rotation around the perforated pipe, and with the possibility of changing the rotation frequency. 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.
