Factors to be considered in selection of drying equipment

1. Physical and chemical properties of materials -- form, water content, water content, crystal water, particle size, bulk density, viscosity, heat sensitivity, softening point, phase change point, thixotropy, toxicity, corrosiveness, peculiar smell, flammability, explosiveness, static electricity, air permeability, agglomeration, and grindability of crystals or particles

2. Drying characteristics of materials -- drying curve, critical moisture content and equilibrium moisture content under the proposed drying conditions.

3. Drying output requirements and long-term planning.

4. The influence of commodity value and drying effect on the material. Such as product moisture, pollution, temperature, wear, pulverization, comminution, rehydration and so on.

5. Requirements for material recovery rate.

6. Up and down process of material drying process. (state method involving feeding and discharging)

7. Past drying methods of materials or similar products.

8. Available heat sources (coal, fuel oil, electricity, gas, liquefied gas, natural gas)

9. Size of installation site and whether there are special requirements.

10. Environmental protection requirements -- restrictions on dust emission, noise, vibration, odor, volatile matter, etc.

11. The amount of possible procurement funds, local labor, land and energy prices.

12. Operator level and maintenance ability of users.

13. Local annual average temperature and humidity.
