vacuum drying equipment selection and application

Vacuum 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, electrostatic property, permeability, agglomeration, crushing 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 impact of commodity value and drying effect of materials on it. Such as product moisture, pollution, temperature, wear, pulverization, grinding, rehydration, etc. on the impact of commodity value.


5. Requirements for material recovery rate.


6. Upper and lower process of material drying. (state method related to feeding and discharging)


7. The 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, whether there are special requirements.


10. Environmental protection requirements - restrictions on dust emission, noise, vibration, peculiar smell, volatiles, etc.


11. The amount of purchase funds that may be invested, and the price of local labor, land and energy.


12. User's operator level and maintenance ability.


13. Local annual average temperature and humidity.
