Equipment for industrial drying. There are various types depending on the properties of the material to be dried. Dryers that use convection drying with hot air include box dryers (textiles, ceramics, etc.), tunnel dryers that move objects inside a container (wood, bricks, etc.), band type (conveyor type), disk type, rotary dryers that use an inclined cylinder (coal, ammonium sulfate, etc.), and flash dryers that use a high-pressure drying air current (pharmaceuticals, food, etc.). Dryers that dry by contact with a pressurized surface include cylindrical dryers (paper, textiles, etc.). Other widely used dryers include vacuum dryers, spray dryers, freeze dryers, and in recent years, those that use infrared rays or high frequency waves. → Desiccants Source : Heibonsha Encyclopedia About MyPedia Information |
