Inside the drying market, we all know each drying device has its specific scope, and each material drying apparatus can be found to meet the basic requirements of a number of species, but there is only one best suited. Such as improper selection, users bear unnecessary addition to a one-time high procurement costs, but also pay a heavy price throughout the life, such as low efficiency, high energy consumption, high operating costs, poor product quality, or even simply means not functioning properly, and so on. Many concerned friends and dried market is immune to recognize your purchase method of drying apparatus, the following general principles drying device selection, it is difficult to say which of the several of the most important, the ideal selection must be based on their own conditions The focus, sometimes compromise is necessary. 1. Applicability ------- drying device must first be able to apply to specific materials, and meet the basic requirements of the dry material, including material handling well (feeding, conveying, fluidization, dispersion, transfer heat, discharge, etc.), and meet the basic requirements of processing capacity, dehydration volume, product quality and other aspects. 2. A high drying rate --- look far as the drying rate, convection drying material highly dispersed in the hot air, the critical moisture content is low, fast-drying, but also with a convection drying, drying methods different critical moisture content is also different, thus the drying rate is also different. 3. Low energy consumption and energy indicators ------- different drying methods vary, but generally dry heat conduction efficiency theoretically up to 100%, convection drying only about 70%. 4. saving investment ----- complete drying device the same function, sometimes significant differences between its cost, should choose those who use their low. 5. Low operating costs --- equipment depreciation, energy, labor costs, maintenance, spare parts and other operating costs ... costs to as low as possible. 6. prefer simple, adequate supply of spare parts, high reliability, long life drying apparatus. 7. comply with environmental requirements, work conditions are good, safe. 8. The former can make the best selection of material drying experiment, in-depth understanding of the drying apparatus similar materials have been used (strengths and weaknesses), often for proper selection of help. 9. not rely solely on past experience, and acquire new technology, listen expert advice.
