1、 Due to being a single layer, it is not possible to achieve flipping and drying, resulting in uneven drying of raw materials, small heating areas, low drying efficiency, low output, high energy consumption, and poor quality.

2、 The conveying flap is a docking structure, and long-term production leads to deformation of the flap, resulting in gaps and material leakage.

3、 Single layer drying furnaces are relatively long, with high operating resistance, thermal expansion, high tension, high failure rate, and a large amount of maintenance.

4、 Large footprint.

5、 Suitable for low-temperature dehydration and drying of grains and grains.
