HEAT AND MASS TRANSFER DEVICE FOR DRYING DISPERSED MATERIALS Russian patent published in 2021 - IPC B01D53/06 F26B17/10 

FIELD: heat and mass transfer equipment.

SUBSTANCE: invention relates to the design of continuous heat and mass transfer devices used for drying dispersed materials and for carrying out endothermic catalytic reactions. The heat and mass transfer device includes a single-pass transport screw that performs the function of an electrically conductive heating element, and the screw surface of which is made like a mesh. At the same time, copper busbars equipped with dielectric gaskets are installed on the outer and inner ends of the single-pass transport screw. The body of the heat and mass transfer device is covered with a layer of thermal insulation. The device is equipped with a thermal control system, which includes a power source with a magnetic contactor, a control device, a setting device, heat temperature sensors for the turns of the transport screw, dispersed material, drying agent at the inlet and outlet of the device.

EFFECT: increase in the productivity of the device during the implementation of mass transfer processes in conditions of fine regulation of thermal modes.
