Description

Technical Field

[0002] At present, dryers are widely used in manufacturing industries such as food, pharmaceuticals and other fields, mainly to remove moisture from materials and improve product stability. With the continuous advancement of drying technology, radiation convection dryers combine the advantages of radiation heating and convection heating, can provide efficient and uniform drying effects, and have been widely used in actual production.

The distances between the heating plate 7 and the fan 4 and the material can be adjusted respectively, so as to improve the production efficiency while ensuring the drying quality of the material. On the other hand, the number and method of the heating wires laid on the heating plate 7 can be adjusted according to the moisture content of the material.
