高效沸腾干燥机High Efficiency Boiling Drier

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

设备呈圆筒形结构，自然空气在风机的抽引下,途经净化柜、加热器,在物料床板小孔中形成高速气流,并使物料呈沸腾状态,在气固两相大面积接触过程中物料中的水分迅速蒸发,从而达到干燥之目的。

高效沸腾干燥机适用于0.1-6mm粒径的颗料状、粉末状物料流态化干燥的新型高效干燥设备，适用于化工、制药、食品、粮食、矿产等行业。也可以用于物料冷却、增湿作业。该机组为分批次间歇干燥生产方式，如：

•   医药工业上片剂，胶囊，冲剂用颗粒； 

•  食品、饲料、化工等领域湿颗粒和粉状物料干燥。

• 螺杆挤压颗粒、摇摆颗粒、高速混合制粒颗粒。

• 大颗粒、小块、粘性块粒状物料。

• 磨芋、聚丙烯酰胺等干燥时体积变化的物料等

   The equipment has a cylindrical structure. Drawn by the fan, natural air runs through the purifying tank and the heater, forms high speed airflows in the small holes of material bed plate and makes the material in the boiling state, so that the water in the material can be evaporated quickly when the gas and the solids contact with a large area. The drying purpose is achieved in this way.

The high efficiency boiling drier is a novel high efficiency drying equipment suitable for the fluidized drying for 0.1-6mm granular and powder-like material. It is applicable in such industries as chemical engineering, pharmaceuticals, food, grains and minerals, and also suitable for material cooling and humidification operation. This unit adopts batch drying production, e.g.:

l   Granules for tablets, capsules and dissolved medicines in the pharmaceutical industry;

l   Drying of wet granules and powdery material in such industries as food, fodder and chemical engineering.

l   Screw extrusion granules, swing granules and high-speed mixed granules.

l   Large granules, small and viscous block granular materials.

l   Material whose volume may change in the drying, e.g., Amorphophallus konjac and polyacrylamide

二、特点Characteristics

1.物料容器采用气缸顶紧，“O"形圈密封，密闭负压操作, 能有效防止物料飞损。

2.顶部配有无纺布过滤袋，并有气缸自动抖袋装置，操作简便,清洗方便,是符合"GMP"要求的理想设备。

3.干燥速度快,温度均匀,每批干燥时间均在20-30分钟。

4.料斗可设置搅拌,避免潮湿物料团聚及干燥时形成沟流。

5.采用翻倾卸料,方便迅速*,亦可按要求设计自动进出料系统。

6.流化床为圆形结构避免死角。

1.    Material containers are tightly held by gas cylinders and sealed with “O" rings. The operation of closed negative pressure can prevent material from damaging.

2.    Its top is provided with nonwoven filter bag and automatic bag shaking equipment for gas cylinder. It is easy to operate and clean and is an ideal equipment complying with “GMP" requirements.

3.    It has a high drying speed and uniform temperature. Each batch takes 20-30 min to dry.

4.    Its hopper has a stirring setting to avoid wet material clotting and forming channeling.

5.    Overturning discharge is adopted. Or an automatic material inlet and outlet system can be designed according to the requirements.

6.    The fluidized bed is a circular structure to avoid dead angle.
