國外沸騰干燥機(jī)介紹一例
|
沸騰干燥機(jī)沸騰干燥機(jī)^適合干燥粒狀結(jié)晶,粗或類似的材料在醫(yī)藥,精細(xì)化工,染料,食品和相關(guān)產(chǎn)品。的流體床干燥器是不適合用于干燥液體或糊狀的材料。沸騰干燥機(jī)的設(shè)計(jì)的產(chǎn)品容器的材料填充在該基地引入熱空氣流。 誘導(dǎo)草案是由風(fēng)機(jī)和新鮮的空氣被吸入到該單位。熱風(fēng)系統(tǒng)擴(kuò)展了床的材料在一定的速度和產(chǎn)生湍流的產(chǎn)品,F(xiàn)象被稱為流化,并提供條件,這幾乎是理想的干燥。 流態(tài)化產(chǎn)生的固體顆粒,充分?jǐn)嚢,因(yàn)槊總(gè)粒子被周圍的熱空氣,熱傳遞非常高,均勻。 將產(chǎn)物干燥快,沒有明顯的熱損失。過濾袋防止從干燥器中逸出的粒子。 沸騰干燥機(jī)占用的建筑面積較小,比較傳統(tǒng)的烘干機(jī)是很容易操作,可以在^少的時(shí)間干料相比,盤式干燥機(jī)。 在流化床干燥機(jī)中,通過了該產(chǎn)品的溫度分布是均勻的熱傳遞率是非常高的。由于高生產(chǎn)率,減少干燥時(shí)間。 由于該產(chǎn)品在低溫和干燥空氣,也作短暫的持續(xù)時(shí)間是在緊密接觸,產(chǎn)品的物理和化學(xué)性能的一般不影響,因此可以有效地被用于熱敏感產(chǎn)品干燥器。 由于產(chǎn)品的連續(xù)運(yùn)動(dòng),在干燥過程中結(jié)塊,滲碳淬火等被^小化。 集裝箱: 制造SS 316與的SS bolliendr的篩,穿孔適當(dāng)?shù)目諝夥植及逄峁┑。集裝箱小車: S.S. 304腳輪支持。阻燃室: 特別設(shè)計(jì)的SS 316阻燃室,具有^佳的噴嘴插入的特殊規(guī)定,與三個(gè)不同的端口。過濾袋殼體: 組成的S.S. 304。由手指形棉過濾袋。 explossion皮瓣的爆炸腔的背面?zhèn)缺辉O(shè)置在安全范圍內(nèi)抑制爆炸壓力。 提供與氣動(dòng)過濾袋振動(dòng)機(jī)構(gòu)。前盤 組成的S.S.304。I.

The fluid Bed dryer is not suitable for drying liquid or pasty materials.Fluid bed dryer is designed to introduce the hot air stream at the base of the product container which is filled with the material. Induced draught is created by means of blower and fresh air is sucked in to the unit. This hot air system expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidization and offer conditions which are almost ideal for drying. Fluidization produces full agitation of solid particles and since each particle gets surrounded by hot air, heat transfer is extremely high and uniform. The product is dried fast without appreciable loss of heat. Filter bags prevent particles escaping from the dryer. Fluid Bed Dryer occupy lesser floor space compare to conventional dryer and are very easy to operate and can dry material in least time as compared to tray dryer. In fluid Bed Dryer, temperature distribution through out the product is uniform and the heat transfer rate is very high. High production rates are achieved due to reduce drying time. As the product is in close contact with drying air at low temperature and also for short duration, the physical and chemical properties of the products are generally not effected and therefore the dryer can effectively be used for heat sensitive products. Due to the continuous movements of product during drying lump formation, case hardening etc. are minimized. Product Container: Made of S.S. 316 & provided with the S.
