The other end of the convection fan sucks air with steam from the other side of the drying box at a certain negative pressure, one part of the air is discharged through a moisture discharging port on the drying chamber and enters a heat recovery system, and the other part of the air returns to the drying chamber to continue heating the materials, and the air is circulated and reciprocated until the materials are dried; the hot air containing water vapor entering the heat recovery system through the moisture exhaust port enters the port 1 of the tubular heat exchanger under the driving of the fan on the circulating system. In the early stage and the later stage of drying, after heat transfer and moisture condensation, the air enters the port No. 3 from the port No. 2 and the filtered air as a heat transfer medium, enters the boiler from the port No. 4, returns to the boiler again, is heated again and enters the heat circulation system; in the middle stage of drying, a valve between the 3# port and the 2# port is closed, so that water vapor and hot air entering the circulating system are exhausted after passing through the heat exchanger, and only the filtered air is allowed to enter the heat exchanger from the 3# port to finish heat transfer and then enters the heat source from the 4# port.

2. Through the use of pipeline conversion valve, in earlier stage and later stage, carry out the utilization for the third time to the hot-air after the heat transfer dehumidification, improved heat source utilization rate, further reduced the stoving energy consumption.
3. The heat source related by the invention is hot air or heated steam and heat conducting oil, so that the pollution of impurities generated by flame combustion to the product is avoided;
4. 2-6 forced convection fans are uniformly distributed on each drying chamber, so that the temperature in the drying chambers is uniform and the drying is consistent;
5. 2-4 moisture discharging openings are uniformly distributed on each drying chamber, and the moisture discharging speed is regulated and controlled and the drying consistency of each drying box is adjusted by adjusting the size of each moisture discharging opening;
6. the heat circulation system is provided with an adjusting valve on each drying chamber, so that on one hand, the heat in the drying chambers can be uniformly distributed, and on the other hand, the heat distribution among the drying chambers can be adjusted through the adjusting valves, and further, the drying consistency of materials in the drying chambers is adjusted;
