Precautions in the production process of the dryer

1. Drying properties of the material - drying curve, critical moisture content, and equilibrium moisture content under the selected drying conditions.

2. Physical and chemical properties of materials - morphology, water content, water content, water of crystallization, particle size, bulk density, viscosity, heat sensitivity, softening point, phase transition point, thixotropy, toxicity, corrosiveness, odor, flammability, explosiveness , electrostatic, gas permeability, agglomeration, crystal or particle smashability ...
3. The impact of material commodity value and drying effect on it. Such as product moisture, pollution, temperature, wear, chalking, crushing, rehydration , etc. on the value of the commodity.
4. Dry production requirements and long-term planning.
5. The upper and lower sequence process of the material drying process. ( involving the state method of feeding and discharging )
6. The requirements of the dryer for material recovery.
7. Available heat sources ( coal, fuel, electricity, gas, liquefied gas, natural gas )
8. The drying method of the material in the past or the drying method of similar products.
9. Environmental protection requirements - restrictions on dust emissions, noise, vibration, odor, volatiles , etc.
10. Installation site size, with or without special requirements.
11. User's operator level and maintenance capabilities.
12. The amount of purchase funds that may be invested, local labor, land, and energy prices.
13. Select the appropriate dryer according to the local average annual temperature and humidity.
