The invention adopts the following technical scheme.
The continuous drier has one drying room, one heating system, one air returning system, one heat conducting wind pore plate and one material conveyer, the material conveyer is below the heat conducting wind pore plate, and the drying room has one wind inlet in the upper part and one inclined wind guiding pore plate in the middle part.
The total area of the holes in the unit area of the heat conducting air hole plates at the two ends of the drying room is larger than that of the holes in the unit area of the heat conducting air hole plates in the middle of the drying room.
The air return system is provided with a water vapor removing device, the water vapor removing device comprises an evaporator, a compressor, a condenser, a throttling device, a water-cooling exchanger, a water pump and a water tank, the evaporator is connected with the compressor, the compressor is connected with the condenser, the condenser is connected with the throttling device, the throttling device is connected with the evaporator, the water-cooling exchanger is arranged beside the evaporator, the water-cooling exchanger is connected with the water pump, the water pump is connected with the water tank, and the water tank is connected with the water-cooling exchanger.
The heating system is provided with an air source heat pump, and a PTC electric heater is arranged beside a condenser of the air source heat pump.
Compared with the prior art, the invention has the advantage of higher drying efficiency.
