The first cavity 101 is located below the conveyor belt 2 and is provided with a first air inlet 1011 for introducing air; the second cavity 102 is located above the conveyor belt 2 and is equipped with a feed port 1021 for allowing the material to be dried to enter the furnace shell 1; and a discharge port 1022 for discharging the dried material. The electric heating element 3 is arranged in the first cavity 101, and multiple electric heating elements 3 can quickly heat the air through electric energy. The centralized air duct 4 is designed in the furnace and is arranged on the same side as the feed port 1021.

[0057] In this embodiment, the concentrated air duct 4 has a second air inlet 401 at both ends, and the second air inlet 401 is connected to the first cavity 101. The air entering from the first air inlet 1011 is heated by the electric heating element 3 inside the first cavity 101, and then enters the concentrated air duct 4 from the second air inlet 401. The hot air entering the concentrated air duct 4 is blown toward the conveyor belt 2 through several air outlets 402 of the concentrated air duct 4, so that the hot air is directly blown toward the material to be dried, so that the material drying effect is better.

[0058] Furthermore, the first air inlet 1011 and the discharge port 1022 are located on the same side of the furnace shell 1 .

[0059] In this embodiment, the first air inlet 1011 and the discharge port 1022 are located on the same side of the furnace shell 1. The advantage of this arrangement is that the air entering the first cavity 101 has the longest heating path in the first cavity 101, so that the air is in full contact with the electric heating element 3.

[0060] Furthermore, the material-distributing blades 8 are two, and the two material-distributing blades 8 rotate in opposite directions.

[0061] In this embodiment, there are two material-leveling blades 8 that rotate in opposite directions. This has the advantage of allowing the material to fall onto the conveyor belt 2 more evenly, allowing the material to be heated more fully, resulting in a better drying effect.
