干燥工艺
湿润的粉末进入 CONTACT FLUIDIZER™ 的逆向混合部分，然后开始蒸发，粉末直接流体化。专用的旋转式洒料车可确保湿润的进料材料连续均匀地分布，这是维持逆向混合部分的“均质化”及其性能的前提条件。半干燥粉末进入活塞流部分，此时粉末的停留时间完全可控制。最后一步，如果需要冷却产品，将使用配有内部冷却面板的活塞留部分延长流化床。
The gas required for the fluidization of the powder is distributed by the GILL PLATE™, tailor-made for the individual plant, to ensure even gas distribution over the bed, good transport of lumps and effective emptying of the fluid bed at shut-down.
When it comes to thermal efficiency, the heating panels submerged into the fluidized powder layer make the design unique because of its highly effective method of transferring the heat from the panels to the powder through the fluidizing gas.
