What are the basic principles of drying equipment selection

  Each type of drying equipment has a specific scope of application, and there are several types of drying equipment that can meet the basic requirements for each material, but only one is the most suitable. If the model is not selected properly, the user will not only bear the unnecessary one-time high purchase cost, but also pay a heavy price for the entire service life, such as low efficiency, high energy consumption, high operating cost, poor product quality, and even the equipment cannot operate normally at all. .

  The following are the principles of drying equipment selection. It is difficult to say which item or items are the most important. The ideal selection must be based on your own conditions, and sometimes a compromise is necessary.

  1. Applicability—The drying equipment must be suitable for specific materials and meet the basic requirements for material drying, including good material handling (feeding, conveying, fluidization, dispersion, heat transfer, discharging, etc.). ), and meet the basic requirements of processing capacity, dehydration capacity and product quality.

  2. High drying rate-as far as the drying rate is concerned, the material is highly dispersed in hot air during convective drying, with low critical moisture content and fast drying speed, which is also convective drying. Different drying methods have different critical moisture content and different drying rates.

  3. Low energy consumption-different drying methods have different energy consumption indicators.

  4. Saving investment-drying equipment with the same function, sometimes the cost difference is large, the lower one should be selected.

  5. Low operating costs-operating costs such as equipment depreciation, energy consumption, labor costs, maintenance costs, and parts costs are as cheap as possible.

  6. Preferred drying equipment with simple structure, adequate supply of spare parts, high reliability and long service life.

  7. Meet the requirements of environmental protection, good working conditions and high safety.

  8. It is best to make a drying experiment of the material before selecting a model, and to have a thorough understanding of the drying equipment (pros and cons) that have been used for similar materials, which is often helpful for proper model selection.

  9. Do not rely entirely on past experience, pay attention to absorbing new technologies, and listen to the opinions of experts.
