    In the drying market, we all know that each drying device has its specific application scope, and each material can find several drying devices that can meet the basic requirements, but only one is suitable for Zui

    If the model selection is improper, users should not only bear the unnecessary one-time high purchase cost, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operation cost, poor product quality, and even the device can not operate normally at all

    Many people who care about the drying market can't recognize the method of purchasing drying device

    The following is the general principle of drying device selection

    It's hard to say which one or several items are important for Zui

    The ideal selection must be focused on according to their own conditions, sometimes it's necessary to compromise

    1

    Applicability ----- the drying device must first be suitable for specific materials and meet the basic use requirements of material drying, including good handling of materials (feeding, conveying, fluidization, dispersion, heat transfer, discharge, etc.), and meet the basic requirements of treatment capacity, dehydration, product quality, etc

    2

    High drying rate - only in terms of drying rate, the material is highly dispersed in hot air during convection drying, with low critical moisture content and fast drying rate

    In addition, with the same convection drying, different drying methods have different critical moisture content, so the drying rate is also different

    3

    Low energy consumption ---- different drying methods have different energy consumption indexes

    In general, the thermal efficiency of conduction drying can reach 100% theoretically, and that of convection drying can only reach about 70%

    4

    Save investment ---- for drying device with the same function, sometimes its cost is quite different, the lower one should be selected

    5

    Low operation cost - equipment depreciation, energy consumption, labor cost, maintenance cost, spare parts cost, etc

    shall be as low as possible

    6

    The drying device with simple structure, sufficient supply of spare parts, high reliability and long service life is preferred

    7

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

    8

    Before selection, Zui should be able to make drying experiments of materials and have a deep understanding of the drying devices (advantages and disadvantages) already used for similar materials, which is often helpful for proper selection
