Description

Technical Field

[0001] The utility model relates to the technical field of microwave dryers, in particular to a stirring device for a tunnel-type continuous microwave dryer. Background Art

[0002] In modern industrial production, the drying process is a crucial step, and its efficiency and effectiveness are directly related to product quality and production costs. Among various drying equipment, tunnel microwave dryers have gradually become the preferred choice in many industries due to their unique advantages, such as fast, precise, and efficient drying performance, as well as perfect preservation of the flavor and color of the material.

[0003] When using the existing tunnel-type microwave dryer, a continuous conveyor belt is used to feed the material into the microwave drying cavity. The material is heated and dried under the action of microwaves, but the spatial position of the material on the conveyor belt cannot be changed, resulting in poor uniformity of microwave drying of the material, thereby affecting the quality of the product. Therefore, we propose a stirring device for a tunnel-type continuous microwave dryer. Utility Model Content
