This simple structure of equipment, easy to operate, difficult to apply toa variety of dry powder materials and granulose Reminxing materials dry. But horizontal flow more room than the thermal efficiency of dryers fluid bed dryers multi-storey low, especially ina hot air temperature, the higher thermal efficiency will be even worse. With the continued development of applied technology, fluid bed dryers patterns and applications is also increasing, equipment classification is different. Over the years, fluid bed dryers have many applications in industry, such as single cylinder-shaped fluid bed, multi-storey cylinder-shaped fluid bed dryers, fluid bed dryers horizontal multi-room, a blender fluid bed, inert particles fluid bed, vibration fluid bed. Fluid bed dryers isa new development in recent years, efficient dryers. Currently in the chemical industry, light industry, medicine, food and other industries has been widely applied, but has gradually extended to Zaoli, calcine, cooling and so on. Dry because Qiguliangxiang current contact dramatic mix. Solid particles suspended in the dry medium, the contact surface is significant, both in heat transfer, transmission quality, volume dry strength, thermal efficiency aspects are fine. Fluid bed dryers operate simple, low labor intensity, good working conditions, overhaul facilities functioning cycle long. The
