Each dryer has its specific scope of application, and each kind of material can find several kinds can meet the basic requirements of the drying device, but only the most suitable have a. Such as improper selection, users in addition to take unnecessary one-time high procurement costs, but also in the pay a heavy price, such as low efficiency, high energy consumption, high operation cost, product quality is poor, even device cannot normal operation and so on.

The following is the general principles of the selection of the dryer, it is hard to say which one or which of the following is the most important and shaping the ideal must be according to their own conditions focus, sometimes compromise is necessary

1.applicability

Drying device must first apply to the specific materials, and meet the basic requirements of dry material, including good material handling (feeding, transportation, fluidization, dispersion, heat transfer, discharge, etc.) and meet the processing quantity, the basic requirements of content, the quality of the products off.

2.high drying rate

Only drying rate, convective drying material is highly dispersed in the hot air, the critical water content rate is low, the drying speed is fast. Also, it is convection drying, drying method of critical moisture content are different, so the drying rate are also different. - belt type dryer.

3.Low energy consumption
Different by different drying methods and the energy consumption index, transmission type drying thermal efficiency theory can reach 100%, the convection drying only 70% or so.
4.Save investment
Complete the same function of the drying device, and sometimes the cost difference between the poor, should choose the low.
5.Low operating cost

Equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts and other operating costs to be as low as possible.

6.Preferred drying device has the advantages of simple structure, adequate supply of spare parts, high reliability and long service life.

7.Meet the environmental protection requirements, working conditions, high safety.

8.The selection of former best can make material drying experiment, in-depth understanding of the advantages and disadvantages of similar materials have been used in the drying device, often on the selection of appropriate help.
