Abstract

The invention discloses a microwave and hot air combined drying machine and unit. The combined drying machine comprises a drying machine body arranged on a conveying belt; microwave heating pipes arearranged inside the drying machine body; and an air passage is arranged inside the conveying belt and is led to the inside of the drying machine body on the surface of the conveying belt. The combineddrying unit comprises a plurality of combined drying machines, and corresponding setting is performed after the plurality of combined drying machines are connected in series, so that hot air enters from the air passage at the bottom end and is discharged from an outlet of the combined drying machine at the top end to form hot-air drying circulation. By the aid of the microwave and hot air combined drying machine and unit, microwave drying and hot air drying can be simultaneously applied to material drying very well, and by the aid of the structural arrangement of the combined drying machine,hot air drying and microwave drying are effectively promoted, so that the drying efficiency and the drying quality are improved.

Description

technical field [0001] The invention relates to a dryer, in particular to a combined microwave and hot air dryer, which belongs to the field of dryer equipment. Background technique [0002] Microwave-hot air combined drying equipment is suitable for food industry, material chemical industry, pharmaceutical industry, ceramic industry and other fields. The existing microwave and hot air drying equipment have complex structures, uneven drying, low drying efficiency, and the drying effect cannot meet the expected requirements. Therefore, inventing and designing a microwave-hot air combined dryer with uniform drying and high drying efficiency has become an urgent problem to be solved. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to design a microwave hot air combined dryer and unit, so that the materials can be dried evenly, with high drying efficiency and good drying effect. [0004] To achieve ...
