After the vapor condenses, the stream enters a reflux drum, where it is split into an overhead product stream, known as the distillate, and a reflux stream that is recycled back to the column. The feed passes through packing to maximize vapor-liquid surface contact for an efficient separation

Apr 01, 2018 · The main disadvantages of rotary atomizers are that they are limited in their ability to handle viscous feeds and cannot be used with short-form spray-dryers. Nozzle atomizers discharge feed liquids under pressure through an orifice as a high-speed stream that breaks into a spray of droplets. Operating pressures range from 250–10,000 psi

Mar 08, 2019 · Drum debarkers are an older technology developed for processing large volumes of lumber. It is an on-mass system, meaning operators feed multiple logs into the debarker and debark them simultaneously. Drum debarkers are composed of a large, rotating cylinder (the drum), the inside surface of which is equipped with ridges (“rifters,” “staves,” or “lifters”)

With single-drum units, the wet paste may be splashed onto the surface of the drum, or the drum may dip into a pool of feed material, as is the commoner practice. Thin materials, in the form of sheets, can be drawn over and under a series of internally-heated cylinders to provide discontinuous thermal contact

When carried out in a rotary dryer, the drying stage has the added benefit of “polishing” the pellets – further rounding them as they tumble through the drum. With some materials, a co-current air-flow serves to flash off residual moisture as material enters the drum. This creates a hardened, re-crystallized surface on the pellet or granule
