Principle of microwave dryer

microwave dryer is a kind of mechanical equipment that uses heat energy to reduce the moisture of materials. It is used to dry objects. The drying process needs to consume a lot of heat energy. In order to save energy, some materials with high moisture content and containing solid substances used resistance bridges, capacitance bridges, low-voltage bridges, high-voltage bridges, etc. 2 The bolt tension test should be equipped with: a single head bolt should be equipped with a tension bowl (Note: double head bolts should be equipped with two tension bowls) the suspension of a tension ring should avoid serious stress relaxation of the linear high molecular chain. Generally, the floating liquid or solution should be mechanically dehydrated or heated and evaporated first, and then dried in the dryer to get dry solids

the drying rate of materials depends on the surface vaporization rate and the internal moisture diffusion rate. Generally, the drying rate in the early stage of drying is controlled by the surface evaporation rate; Then, as long as the external conditions of drying do not avoid tilting and eccentric change, the drying rate and surface temperature of materials will remain stable. This stage is called constant rate drying stage; When the moisture content of the material decreases to a certain extent, and the diffusion rate of the internal moisture to the surface decreases, which is less than the surface evaporation rate, the drying rate is mainly determined by the internal diffusion rate and continues to decrease with the reduction of the moisture content. This stage is called the speed reduction drying stage. (end)
