Drytech Engineering | Indirect Dryers
The feed is introduced at the feed end and is conveyed through the length of the dryer being brought into contact with the heated surfaces. The constant motion and agitation of the screw or paddle exposes new surfaces and intimately mixes the product. Dry product is discharged from the opposite end of the unit. The evolved moisture is exhausted from the system through an …
Indirect rotary dryers | IDRECO S.r.l.
Indirect Heated Fired Rotary Dryers. Indirect Heated Fired Rotary Dryers are commonly used for carbon black pellets drying. Carbon black coming from the reactor, which is not part of Idreco technology, is fed to a wet pelletizer where water together with molasses are added to form wet pellets. Molasses are used as a binder for beading / pelletising of carbon black particles, as …
Indirect Rotary Dryers - Vulcan® Drying Systems
Vulcan® Indirect Rotary Dryers rely on the heat transferred through the drum’s shell to dry the material via conduction and radiation to reduce the material’s moisture content. Indirect drying allows you to tightly control the processing environment, an ideal characteristic when working with materials that can be combustible or where higher temperatures are required to remove bound …

Heat Transfer Screw Processor Manufacturer | …
KWS Heat Transfer Screw Processors indirectly transfer heat to or from bulk materials by introducing a heat transfer medium such as cool water, hot oil or steam through a special trough jacket and/or center pipe and hollow flights. Cooling or heating a bulk material to a desired exit temperature is accomplished by the surface area of the screw processor and designing the system flow to match the heat load …
Indirect Drying vs. Direct Drying - FEECO …
Indirect dryers rely on the heat emanating from the drum’s shell to dry the material via conduction and radiation. Subsequently, indirect dryers would not benefit from the addition of lifting flights, since there is no process gas moving through the drum. Furthermore, because the furnace exhaust is kept separate from the process gas, indirect dryers have the added …

1 Fundamentals of Energy Analysis of Dryers
1) Thermal inefficiencies in the dryer: exhaust heat content in convective dryers, sensible heating of solids, heat losses from dryer body. 2) Thermal inefficiencies in the utility (heat supply) system: steam generation efficiency, steam leaks and mains losses. 3) Additional energy demands: power for solids transport, vacuum pumps and air fans.
Improving Indirect Heat Transfer to Solids By Better Mixing
Improving Indirect Heat Transfer to Solids By Better Mixing By William L. Root Komline-Sanderson Engineering Corporation Peapack, New Jersey Abstract This review of literature citations relates how mixing affects the heat transfer rates to solids in a variety of processing units. These units will include pan, horizontal (rotary vacuum), screw conveyor and paddle dryers …
Paddle dryer - ANDRITZ
A direct dryer uses hot air flow for both functions. Usually a lot of heat is wasted in the exhaust – and a lot of dust is created and consequent foul smelling - requiring expensive equipment for removal. Solvent recovery can be a problem too. An indirect dryer avoids all these problems: air flows, where present at all, are negligible ...
