To further provide for adequate drying of the material, the material conveyor may optionally include a plurality of material conveyors, such as, but not limited to, an odd number of material conveyors. Alternatively, the material conveyor may be 1, 3, 5, etc.

As an example, the right end of the middle material conveyor belt 31 may be closer to the right end of the material drying box 10 than the upper material conveyor belt 14, so that the material may automatically fall to the right end of the middle material conveyor belt 31 after being separated from the right end of the upper material conveyor belt 14, and may be conveyed to the left end of the material drying box 10 along with the middle material conveyor belt 31. Compared with the middle material conveying belt 31, the left end of the lower material conveying belt 15 can be closer to the left end of the material drying box 10, so that the left end of the lower material conveying belt 15 can be automatically dropped from the left end of the middle material conveying belt 31, the material can be conveyed to the right end of the material drying box 10 along with the lower material conveying belt 15, the material is conveyed in a reciprocating mode, moisture in the material is taken away by hot air in the process, and material drying is achieved.

Alternatively, the heat exchange gas inlet 28 may be disposed below the lower material conveyor belt 15, for example, but not limited to, the heat exchange gas inlet 28 may be disposed on the front end wall of the material drying box 10, so as to uniformly distribute the air below the material conveyor belt by controlling the air inlet speed of the heat exchange gas inlet 28. Alternatively, a plurality of heat exchange gas inlets 28 may be provided at intervals in the conveying direction of the material, for example, but not limited to, a plurality of heat exchange gas inlets 28 may communicate with the blast passage 17 so that the gas of each heat exchange gas inlet 28 has the same temperature.

Further, heat transfer gas export and heat transfer gas import 28 can be crisscross the setting on material conveying direction, and the heat transfer gas export can be located between two adjacent heat transfer gas imports 28 promptly, so gaseous can rise along tortuous path in the mummification incasement to carry out abundant contact with the material, thereby improve the utilization ratio of energy.
