Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a novel tunnel-type microwave drying machine. Background Art

[0002] Microwave drying is a novel drying method. During drying, microwave energy directly acts on the medium molecules, converting them into heat. Because microwaves are penetrating, they heat the medium both inside and out simultaneously, eliminating the need for heat conduction. This results in extremely rapid heating. For foods with a moisture content below 30%, the drying rate can be shortened by hundreds of times. Furthermore, regardless of the shape of the object, since the medium is heated both inside and out, the temperature difference between the inside and outside of the material is minimized, resulting in even heating. This eliminates the burning of the outside and the growth of the inside that can occur with conventional heating, significantly improving drying quality.
