each drying equipment has its specific application scope, and each material can find a number of drying equipment to meet the basic requirements, but the most suitable only one. if the selection is improper, users should not only bear the unnecessary one-time high procurement costs, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even the normal operation of equipment and devices.
following is the general principle of drying equipment selection, it is difficult to say which or which is the most important. ideal selection must be based on their own conditions, and sometimes a compromise is necessary.
1. applicability - --- drying equipment must first be able to apply to specific materials, and meet the basic requirements of material drying, including good handling of materials (feed, transport, fluidization, dispersion, heat transfer, discharge, etc.), and to meet the basic requirements of processing capacity, dehydration capacity, product quality and so on.
2. high drying rate - in terms of drying rate only, materials are highly dispersed in hot air during convective drying, with low critical moisture content and fast drying speed, and the same is convective drying. different drying methods have different critical moisture content, so the drying rate is different.
3. low energy consumption - - - different drying methods have different energy consumption indicators. the thermal efficiency of conductive drying can reach theoretically, and convective drying can only reach about 70%.
4. save investment - --- drying device with the same function, sometimes its cost varies greatly, so the lower one should be chosen.
5. low operating costs - equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs, etc. should be as low as possible.
6. priority should be given to drying devices with simple structure, adequate supply of spare parts, high reliability and long service life.
7. it meets the requirements of environmental protection, has good working conditions and high safety.
8. it's better to do material drying experiment before type selection. it's often helpful for proper type selection to have a thorough understanding of the drying devices used for similar materials (advantages and disadvantages).
9. not totally dependent on past experience, pay attention to absorbing new technologies and listen to experts'opinions.
