DOUBLE-CHAMBER DRIER Russian patent published in 2017 - IPC F26B19/00 

FIELD: machine engineering.

SUBSTANCE: dryer comprises a drying agent generator, a gas conduit, a drying chamber comprising a hopper for material to be dried, and having gas-permeable walls connected to at least one gas-permeable wall with a drying agent collector. The chamber has means for loading and unloading the material to be treated, means of its control, means for attaching the chamber to the foundation. The end wall of the chamber is connected to a diffuser. There are heat-insulating gaskets, gates, a control unit and a second drying agent generator, a gas line and the diffuser additionally introduced into the drier. The drier comprises two drying channels, each channel of which contains two heat-insulating gaskets, two gates, a drying chamber. The control unit contains a time generator, a counter, a multiplexer, two switches, an inverter and a switch. Each drying channel contains a drying chamber which, on the one side, through the first diffuser, the slide, the heat insulating gasket, the first gas line is connected to the first generator of the drying agent, and on the other side through the second diffuser, the slide, the heat-insulating gasket, the second gas line is connected to the second generator of drying agent. The output of the control unit time generator is connected to first input of the counter, which second input is connected to the input of first key and through inverter with the input of the second key and the output of the multiplexer. The first input of the multiplexer is connected to the output of the counter, and the second input-to the switch input. The output of first key of control unit is connected to control input of the first slide of first channel and the second slide of the second channel. The output of second key is connected to control input of the first slide of the second channel and the second slide of the first channel.

EFFECT: improved drying quality, reduced its performance time, reduced power consumption.
