Drying cotton fiber in a gin is heavily dependent on exposure of heated drying air to the moist fiber surfaces of the clumps of moist trashy cotton.  This is no different than the reason that a household clothes dryer mechanically tosses moist cotton clothing within the flow of heated air to more quickly dry the garments.  As you might imagine, if that clothes drying process involved the wet clothes sitting in a clump while hot air passed over them, the process would not be fast or efficient.  The Double-Flail effectively opens and single-locks clumps of cotton arriving from the module feeder and does so directly in the path of the heated air.  As the heavy chains rotate to break up this mass of fiber, there is slippage of hot air across the opened cotton that enhances the drying effect even before the cotton enters a dryer. 

 

Any cotton gin dryer is benefitted from a Double-Flail opening the fiber as chokes will be eliminated and turbulence within the dryer will be more effective.  More importantly, inclined cleaning machinery downstream of the dryer will clean more effectively with the smooth steady flow of cotton that comes from having a Double-Flail upstream in the process.  Cotton surges from the module feeder don’t stand a chance of choking things downstream in the dryer and cleaning machinery with a Double-Flail standing guard between them.  A Double-Flail works equally well on conveyor and blow-box cotton pickup systems as well as pull-through or push-pull air system designs.  It is the easiest and most economical boost that a gin can give its drying and cleaning system.
