沸腾（流化）制粒干燥机Boiling (Fluidized) Pelletizing Drier

沸腾制粒干燥机

一、工作原理及应用范围介绍Introduction of Working Principle and Scope of Application

沸腾制粒方法是喷雾技术和流化技术的综合运用。 粉状物料投入料斗内密闭，在负压热气流的作用，床体内的粉末物料悬浮呈流化状循环流动，流化的同时也呈均匀混料状态，同时喷入雾状粘结剂润湿容器内的粉末，使粉末凝成疏松的小颗粒，成粒的同时，热气流对其作高效干燥，水份不断蒸发，粉末不断凝固，最终形成理想的、均匀的多微孔球状小颗粒物料粉末粒子。 

沸腾流化制粒干燥机是将混合、制粒、干燥过程在同一设备内一次完成， 故又称“一步制粒机”。该机组为分批次间歇干燥生产方式。

本机广泛运用于制药、食品工业中片剂、冲剂、颗粒果汁、调味品等造粒、包衣，也可用于农药、化工行业农药、饲料、化肥、染料等。

The boiling pelletizing method incorporates spray technology and fluidization technology. Powdery material is put into the hopper and enclosed. Under the action of negative pressure hot air, the powdery material inside the bed suspends and circularly flows in the fluidizing state. It is uniformly mixing when fluidizing, and at the same time mist-like binder is injected in to moisten the powder in the container so that the powder congeals into small loose granules. During the pelletizing, the hot air dries the material efficiently; water evaporates unceasingly; the powder congeals consistently, so ideal and uniform porous spherical powder granules are produced finally. The boiling fluidized pelletizing drier is to complete the mixing, pelletizing and drying processes at a time inside a same equipment, therefore it is also known as “one-step pelletizing drier”. This unit adopts batch drying production.

This equipment is widely applied to pelletizing and coating the tablets, dissolved medicines, juice granules and condiment etc in the pharmaceuticals and food industries, and also applicable to pesticides, chemical engineering pesticides, fodder, chemical fertilizer and dyes etc.
