In the dry market, we all know that each drying device has its specific scope of application, and each material can find a number of drying devices that meet the basic requirements, but only one is the most suitable. In the case of improper selection, the user should pay a heavy price in the whole period of use, such as low efficiency, high energy consumption, high running cost, poor quality of the product, or even the normal operation of the device.
  Many friends who are concerned about the dry market are difficult to recognize the way to buy a drying device. The following is the general principle of drying device selection. It is difficult to say which or which items are the most important. The ideal selection must be based on their own conditions, sometimes it is necessary to compromise.
  1.Applicability - drying equipment must first be applicable to specific materials and meet the basic requirements of material drying, including good handling of materials (feed, transport, fluidization, dispersion, heat transfer, discharge, etc.), and meet the basic requirements of processing, water removal, and quality of products.
  2.The drying rate is high - as far as the drying rate is concerned, the material is highly dispersed in the hot air when drying, and the critical moisture content is low, the drying speed is fast, and the same is convective drying, and the different critical moisture content of the drying method is different, so the drying rate is also different.
  3.Low Energy Consumption - --- Different drying methods have different energy consumption indicators, the general thermal efficiency of conductive drying can theoretically reach 100%, convective drying can only be about 70%.
  4.Save investment - - drying equipment that performs the same function, and sometimes the cost is very different.
  5.Low operating costs - equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts and other expenses should be as low as possible.
  6.Priority is given to selecting a drying device with simple structure, adequate supply of spare parts, high reliability and long service life.
  7.It meets the requirements of environmental protection, good working conditions and high safety.
  8.It is better to do the drying experiment of the material before selecting the type, and to understand the drying device (advantages and disadvantages) of the similar material already used, which is often helpful for the proper selection of the type.
  9.Instead of relying solely on past experience, we should focus on absorbing new technologies and listen to experts' opinions.
