With other short-time dryers, the product motion is in the form of a vortex flow driven by the hot gas which increases the residence time. This can be achieved with hot gas jets tangentially entering the drying area (vortex flow dryers such as helical flow tube with nozzles and annular flow dryer [5.77]), with displacement internals including gas guide vanes (spiral tube pneumatic dryer [5.78, 5.79]), or with tapered inclined perforated screen (cyclone dryer [5.80]). The convex dryer [5.81, 5.82] combines the functions of drying and classifying. With a... 

Dependences for calculation on a water resistance in various types of air swirlers are offered vaned, tangential, scroll, with spiral and flat guide vanes.
