沸騰（流化）制粒干燥機Boiling (Fluidized) Pelletizing Drier

沸騰制粒干燥機

一、工作原理及應(yīng)用范圍介紹Introduction of Working Principle and Scope of Application

沸騰制粒方法是噴霧技術(shù)和流化技術(shù)的綜合運用。 粉狀物料投入料斗內(nèi)密閉，在負壓熱氣流的作用，床體內(nèi)的粉末物料懸浮呈流化狀循環(huán)流動，流化的同時也呈均勻混料狀態(tài)，同時噴入霧狀粘結(jié)劑潤濕容器內(nèi)的粉末，使粉末凝成疏松的小顆粒，成粒的同時，熱氣流對其作高效干燥，水份不斷蒸發(fā)，粉末不斷凝固，最終形成理想的、均勻的多微孔球狀小顆粒物料粉末粒子。 

沸騰流化制粒干燥機是將混合、制粒、干燥過程在同一設(shè)備內(nèi)一次完成， 故又稱“一步制粒機"。該機組為分批次間歇干燥生產(chǎn)方式。

本機廣泛運用于制藥、食品工業(yè)中片劑、沖劑、顆粒果汁、調(diào)味品等造粒、包衣，也可用于農(nóng)藥、化工行業(yè)農(nóng)藥、飼料、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.
