Each dryer device has its specific scope of application, and each material can find several drying devices that can meet the basic requirements, but only one is suitable
.
If the model is improperly selected, the user will not only have to bear the unnecessary one-time high purchase cost, but also pay a heavy price during the entire service period, such as low efficiency, high energy consumption, high operating cost, poor product quality, and even fundamental installation.
not functioning properly,
etc.
The following are the general principles of dryer selection.
It is difficult to say which item or items are important.
The ideal selection of electric blast drying oven must be emphasized according to its own conditions, and sometimes a compromise is required
.
1.
Applicability ------- The drying device must be suitable for specific materials and meet the basic requirements for drying materials, including the ability to handle materials well (feeding, conveying, fluidization, dispersion, transmission, etc.
).
heat, discharge, etc.
), and can meet the basic requirements
of processing capacity, dehydration capacity, product quality, etc.
2.
Do not rely on past experience, focus on absorbing new technologies, and listen to the opinions of experts
.
3.
Low energy consumption ------- Different drying methods have different energy consumption indicators.
Generally, the thermal efficiency of conduction drying can reach theoretically, and convection drying can only be about 70%
.
4.
Meet the requirements and have good working conditions
.
5.
Saving investment-----An anti-corrosion coating drying device with the same function, sometimes its cost is very different, and the lower one should be selected
.
5.
Low operating costs---equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs.
.
.
The operating costs of electric blast drying ovens should be as low as possible
.
6.
The drying device with simple structure, sufficient supply of spare parts, high reliability and long service life is preferred
.
7.
High drying rate---Only in terms of drying rate, the material is highly dispersed in hot air during convection drying, the critical moisture content is low, and the drying speed is fast, and both are convection drying, and the critical moisture content is different for different drying methods.
Drying rates are also different
.
8.
Before the selection, it is possible to make a drying experiment of the material, and to have an in-depth understanding of the drying devices (advantages and disadvantages) that have been used for similar materials, which is often helpful for proper selection
.
