[0002] Patent document CN118031574A discloses a tunnel-type microwave vacuum ultra-low temperature drying device and material drying process for drying materials. The tunnel-type microwave vacuum ultra-low temperature drying device comprises: a main unit comprising a cavity having a cylindrical structure and a plurality of microwave generators; the cavity having a regular polygonal cross-section; the plurality of microwave generators being disposed on the outer wall of the cavity and arranged sequentially along at least the length of the cavity; a vacuum unit, the vacuum port of the vacuum unit being connected to the cavity via a pipeline; and a chiller, the cooling water pipe of the chiller being connected to the microwave generators and used to cool the microwave generators. By utilizing the property of microwaves that polar molecules oscillate and generate heat, and aided by the vacuum unit to evacuate the cavity, the water-containing material in the cavity is rapidly evaporated at low temperature within the vacuum environment, achieving drying efficiency and preventing damage to the material due to excessive temperature. Although multiple microwave generators are installed above and on both sides of the cavity, since the conveyor can only transport material pallets in a straight line, it is difficult to dry the material more carefully in all directions and at multiple angles.
