多层振动流化床干燥机工作原理及特点

多层振动流化床干燥机是化工产品干燥的一种新型设备，是单层流化床干燥机的一种改进形式。这种干燥机在干燥箱结构，孔板结构及调整等方面，比以往干燥设备具有极大改进。本文从振动和风力两个角度出发，着重介绍了这种干燥机的工作原理，物料的运动情况和干燥过程，明确分析了它的特点和应用。

Principle and Characteristic of a Multilayer Vibrating Fluidized Bed Type of Drier

Multilayer vibrating fluidized bed type of drier,ah a substitute for a monolayer fluidized bed type of drier,is a new one for drying chemical products.The structure and adjusting of drying box and orifice has further improved.From a viewpoint of vibration and air force,the principle,motion of the materials and drying process in the drier were discussed and the charactcristic and application of the drier were analyzcd。
