关头词:dedert环式枯燥机

dedert环式枯燥机利用当产物不能有用地在单通的闪蒸枯燥机枯燥的环境下,出格是散,膏,蛋糕或泥浆,须要耽误枯燥时候,dedert的环式枯燥机处理计划。

差别的手艺之间的闪蒸枯燥机和环式枯燥机分类器(气歧管),从而使半枯燥产物的再轮回额定的枯燥和分离的初始热区注册建立。这分类完成经由进程调剂叶片切成已离心分类的资料的层。分流叶片的调剂和设置,由及格的dedert工程师环机的调试进程中,须要调剂一次设置。

光环上的干衣机的收受接管资料许可的排气温度绝对较低时要利用的完成所需的^终水份含量。枯燥效力的进步和产物品质的变更是无限的。

dedert设想并建成了天下上^大的半封锁的环机179,000 acfm是在一个单一的单元,能够或许以每小时34吨的水蒸发。

dedert's fluid bed dryer provides for gentle yet efficient drying action, which is ideal for friable or soft agglomerated particles with a fairly narrow particle size distribution and medium size particles (200 – 400 microns).

product is fluidized by the process gas stream entering the dryer through the distributor plate. dedert has a variety of distributor plates available depending on the application.

process drying air could be designed as multi-zone to enhance drying characteristics in different parts of the bed. exhaust air leaves the dryer through a hood and is further cleaned in cyclones or bag filters to maximize product recovery while meeting emission guarantees.

fluidized heating and cooling zones can be integrated into a single unit in a fluid bed dryer. submerged extended surface heat exchangers can also be incorporated: this approach maximizes the heat transfer rate. submerged heat transfer area can be retrofitted to existing fluid bed dryers to increase evaporative capacity.

ring dryers

dedert ring dryers are used when products cannot be efficiently dried in single pass flash dryers. in cases where particular powders, pastes, cakes or slurries require extended drying times, the dedert ring dryer is the solution.

the differentiating technology between the flash dryer and the ring dryer is the incorporation of a classifier (manifold), which enables the recirculation of semi-dried product back to the initial heat zone for additional drying and dispersion. the classifier achieves this by the adjustment of blades which cut into the layer of material that has been centrifugally classified. the splitter blades are adjusted and set by qualified dedert engineers during the commissioning of the ring dryer and need not be adjusted once set.

the recycled material on the ring dryer allows a comparatively lower exhaust temperature to be used while achieving the desired final moisture content. drying efficiency is improved and variations in product quality are limited.

dedert has designed and built the world’s largest partially-closed ring dryer at 179,000 acfm and is able to evaporate 34 tons of water per hour in a single unit.
