Selection of drying equipment

1. Physical and chemical properties of materials -- shape, water content, water content, Water of crystallization, particle size, bulk density, viscosity, heat sensitivity, softening point, phase change point, Thixotropy, toxicity, corrosiveness, odor, flammability, explosiveness, static electricity, permeability, agglomeration, crystal or particle fragility
2. Drying characteristics of materials - drying curve, critical moisture content, and equilibrium moisture content under the proposed drying conditions.
3. Drying yield requirements and long-term planning.
4. The impact of material commodity value and drying effect on it. Such as product moisture, pollution, temperature, wear, pulverization, crushing, rehydration The impact on the value of goods.
5. Requirements for material recovery rate.
6. The upper and lower process of material drying. (State methods related to feeding and discharging)
7. Previous drying methods for materials or similar products.
8. Available heat sources (coal, fuel oil, electricity, gas, liquefied gas, natural gas)
9. The size of the installation site and any special requirements.
10. Environmental requirements - for dust emissions, noise, vibration, odors, volatiles Restriction conditions such as.
11. Possible procurement funds, local labor, land, and energy prices.
12. The user's operator level and maintenance ability.
13. Local average annual temperature and humidity
