ABSTRACT
Larger volummes of air are being unnessarily used in many of today's drying systems to try and keep the temperature up for longer periods of exposure time, thus reducing the temperature loss towards the end of the drying cycle caused by the evaporation of moisture. These larger volummes add substantially to energy costs as well as emission control costs. With the Turbulent Flow Hot Shelf Drying System, much smaller volummes of air are used with much lower power requirements, because the temperature drop is avoided through-out the system. This is accomplished through an arrangement of heat chambers between the shelves, from which heat is transferred to the shelves conveying the cotton. This same air used for the heat chambers is either re-circulated through the system on a continuous basis, or put back into, and combined with the primary air line to pick up the cotton at the mix point and convey it to the tower.
