高效沸騰干燥機High Efficiency Boiling Drier

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

設(shè)備呈圓筒形結(jié)構(gòu)，自然空氣在風(fēng)機的抽引下,途經(jīng)凈化柜、加熱器,在物料床板小孔中形成高速氣流,并使物料呈沸騰狀態(tài),在氣固兩相大面積接觸過程中物料中的水分迅速蒸發(fā),從而達到干燥之目的。

高效沸騰干燥機適用于0.1-6mm粒徑的顆料狀、粉末狀物料流態(tài)化干燥的新型高效干燥設(shè)備，適用于化工、制藥、食品、糧食、礦產(chǎn)等行業(yè)。也可以用于物料冷卻、增濕作業(yè)。該機組為分批次間歇干燥生產(chǎn)方式，如：

•   醫(yī)藥工業(yè)上片劑，膠囊，沖劑用顆粒； 

•  食品、飼料、化工等領(lǐng)域濕顆粒和粉狀物料干燥。

• 螺桿擠壓顆粒、搖擺顆粒、高速混合制粒顆粒。

• 大顆粒、小塊、粘性塊粒狀物料。

• 磨芋、聚丙烯酰胺等干燥時體積變化的物料等

   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、特點Characteristics

1.物料容器采用氣缸頂緊，“O"形圈密封，密閉負壓操作, 能有效防止物料飛損。

2.頂部配有無紡布過濾袋，并有氣缸自動抖袋裝置，操作簡便,清洗方便,是符合"GMP"要求的理想設(shè)備。

3.干燥速度快,溫度均勻,每批干燥時間均在20-30分鐘。

4.料斗可設(shè)置攪拌,避免潮濕物料團聚及干燥時形成溝流。

5.采用翻傾卸料,方便迅速*,亦可按要求設(shè)計自動進出料系統(tǒng)。

6.流化床為圓形結(jié)構(gòu)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.
