Each
Drying Machine has its specific scope of each type of materials can be found in several drying device to meet the basic requirements, but only a most suitable. Improper selection of the user to bear unnecessary disposable high procurement costs, but also to pay a heavy price throughout the life of, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even the device is simply not normal operation and so on.
The following are the general principles of the drying device selection, it is difficult to say which of the several most important, the ideal selection must be focused on their own terms, sometimes compromise is necessary.
1. The applicability ------- drying device first must be able to apply to specific materials, and to meet the basic use of dry materials requirements, including materials handling well (feeding, conveying, fluidization, dispersion pass heat, discharge, etc.), and to meet the basic requirements of the handling capacity, dehydration, and product quality.
High drying rate --- only in respect of the drying rate of view, materials are highly dispersed in the hot air convection drying, the critical low moisture content, dry fast, and with convective drying, critical moisture content is also different drying methods, thus The drying rate is also different.
3 low-energy ------- different indicators of energy consumption of different drying methods generally dry heat conduction efficiency theoretically up to 100%, the convection drying only about 70%.
Saving investment ----- complete drying device of the same features, sometimes significant differences between its cost, its low choice for those who should be optional.
Low running costs --- depreciation of equipment, energy-consuming, labor costs, maintenance costs, spare parts fee ... and other operating costs as low as possible.
Select a simple structure, an adequate supply of spare parts, high reliability, long life and the drying device.
7. Meet environmental requirements, working conditions and safety.
Before Selection is best to make the material drying experiments, in-depth understanding of the use of similar materials drying device (strengths and weaknesses), tend to help in the proper selection.
Not completely rely on past experience, focusing on the absorption of new technologies, more than to listen to the opinions of experts.
