Microwave drying device capable of integrating preheating and strong wind heat dissipation

Abstract

The invention discloses a microwave drying device capable of integrating preheating and strong wind heat dissipation. The microwave drying device comprises a belt conveyor, wherein a preheating bin isarranged at the starting end of the belt conveyor, a microwave drying bin is fixedly connected with the preheating bin, and at least one microwave generator is fixed on the upper side of the interiorof a microwave heating box; a spiral distributor is arranged at the joint of the preheating bin and the microwave drying bin, a dehumidification device and an axial flow fan are sequentially connected in series on a heat collection pipe, a strong fan is arranged below the belt conveyor, and a control cabinet is connected with the belt conveyor, the microwave generators, the axial flow fan or thestrong fan. Materials are subjected to drying treatment by adopting a microwave heating technology, and rapid drying of the materials can be achieved through microwaves. According to the microwave drying device, in the process of drying the materials, logistics in the microwave drying bin is timely subjected to heat dissipation and dehumidification, the emitted heat in the microwave drying bin isreturned into the preheating bin, the materials are preheated in the preheating bin, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of microwave heating, in particular to a microwave drying device integrating preheating and strong wind heat dissipation. Background technique [0002] Microwave heating technology is based on the absorption of microwave energy by materials, which is the result of the interaction between polar molecules in materials and microwave electromagnetic fields. Orientation, so many polar molecules are frequently rubbed against each other, so that electromagnetic energy is converted into heat energy, etc., which are related technologies for heating materials. Microwave heating is completely different from traditional heating methods. It is a process that makes the heated material itself a heating element without heat conduction. [0003] The traditional material heating method generally uses the heat generated by fuel combustion or electric energy to heat the material. This method of heating the material has defects...

AI Technical Summary

Problems solved by technology

[0004] The microwave heating devices currently on the market generally use a simple microwave heating device to heat the material, but the thermal efficiency of this device is not high, and the heat emitted during the microwave heating process cannot be fully utilized. At the same time, the heat dissipation effect during the material heating process is also poor Not good, the heat on the surface of the material or the water vapor emitted during the heating process cannot be removed in time, resulting in poor heating effect
