Product Description Drum dryer isused for drying out liquids from raw materials with drying drum. In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product. The drum dryer is suitable for fuel plant, fertilizer plant, chemical plant, pharmaceutical and other industries.

The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights and the speed of rotation. However, irrespective of the gas and material temperatures the drying (or residence) time may be critical, as this is governed by the rate of diffusion of water from the core to the surface of the material. For special applications, the rotary cascade design is adapted to provide a shortfall, or 'Cruciform', lifter configuration. Similarly, Rotary Cascade Coolers and Combined Dryer/Coolers are available as required.Features of the Rotary DryingRobust constructionPermits use of higher drying temperaturesRelatively long residence timeDrum provides dispersion as material is conveyed along the lengthBenefits of Rotary DryingCombines flexibility with reliability resulting in a long service life. The rotary is also suitable for operation with a wide range of materials & particle sizes and can more readily accommodate 'upset' up-stream process conditionsCo-current is suitable for materials with relatively high moistures and provides rapid evaporation without overheating the product. Counter-current has the greatest thermal gradient and helps achieve low product moisturesReduces equipment size and the associated capital and operating costsPromotes diffusion dryingRelatively low fan power and low headroomEnables energy savingsOUR PROJECTSOUR CERTIFICATETHE CLIENTS WITH USOUR SERVICPre-sale service1.Our professional and experienced engineer team helps every client to find his most suitable equipment or chose of plant.2.
