Each drying device has its specific scope of application, and each material can find a number of drying devices that can meet the basic requirements, but only one is the most suitable. If the model is not selected properly, the user should not only bear the unnecessary one-time high procurement cost, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operation cost, poor product quality, and even the device can not operate normally, etc.
The following are the general principles for the selection of drying equipment. It is difficult to say which one or several are the most important. The ideal selection must be based on one's own conditions, and sometimes a compromise is necessary.
1. Applicability: the drying device must be suitable for specific materials and meet the basic requirements of material drying, including good material treatment (feeding, conveying, fluidization, dispersion, heat transfer, discharge, etc.), and meet the basic requirements of treatment capacity, dehydration, product quality, etc.
2. High drying rate --- in terms of drying rate, the details of surrogacy http://www.juzhixian.com/ In convection drying, the material is highly dispersed in the hot air, the critical moisture content is low, and the drying speed is fast. In addition, the same convection drying, different drying methods have different critical moisture content, so the drying rate is also different.
3. Low energy consumption --- different drying methods have different energy consumption indexes. In general, the thermal efficiency of conductive drying can reach 100% in theory, while that of convective drying can only reach about 70%.
