When we use microwave drying equipment, we must have a certain amount of comparison before selecting it, so that we can find the equipment that is suitable for us when selecting it. If we choose the equipment that is not suitable for us, the use effect will be greatly reduced when using it. At this time, we need to have a certain understanding of the equipment. So how do we choose? Let's have a look.

First of all, in terms of the efficiency of microwave drying, the materials are highly dispersed in hot air during convective drying. The critical moisture content is low and the drying speed is fast. In addition, the same convective drying, the critical moisture content is different with different drying methods, so the drying rate is also different.

The second is the applicability of the selected microwave drying equipment. The drying equipment must be applicable to specific materials and meet the basic requirements for material drying. Including good treatment of materials (feeding, conveying, fluidization, dispersion, heat transfer, discharge, etc.) and meeting the basic requirements of treatment capacity, dehydration, product quality, etc.

In terms of operating cost, it can be divided into energy consumption and investment cost. Different drying methods have different energy consumption indicators. Generally, the thermal efficiency of conduction drying can reach 100% in theory, and that of convection drying can only be about 70%. Of course, cost input is another important factor to be considered when selecting drying equipment. If the drying device can complete the same function, it should be used when it is low.

After learning about the choice of microwave drying equipment, we will make a certain choice about its purchase.
