Each dryer has its specific scope, and each item can be found several ways to satisfy the basic requirements of drying equipment, but there can be only one of the best. As improper selection, in addition to bear unnecessary high disposable purchase costs, and paid a heavy price during the entire period, such as low energy consumption, high efficiency, high operating costs, poor quality products and even device does not function properly and so on. Following are general principles of drying equipment selection, it's hard to say which one or which is the most important, the ideal focus selection must according to the conditions, and sometimes compromise is necessary.

1.Applicability-drying device must first apply to a specific item, and meet the basic requirements of dry material.

2. The drying rate is high-only the drying rate, highly dispersed in the hot air convection drying materials, critical moisture content low, fast-drying, and convection drying. Drying method of critical water content is also different, thus the drying rate is also different.

3.Low energy consumption-different drying methods different energy consumption indicators and conductive style dryer heat efficiency theoretically could reach 100%.

4. The savings investment-accomplishes the same function of drying equipment, sometimes the cost difference, that should choose the lowest-bid selection.

5. Before the selection of the best material drying experiments, insight into similar material has been used dryer, often is helpful to appropriate selection.

6.Do not rely on past experience, pay attention to absorb new technology, listen to expert opinion.
