Citation: MANGIALARDI, JR, G.J., ANTHONY, W.S. RETROSPECTIVE VIEW OF COTTON GIN DRYERS. NATIONAL COTTON COUNCIL EDUCATIONAL BROCHURE. 2003. 54 pgs. Interpretive Summary: Many dryer designs have been used to dry seed cotton at cotton gins since the late 1920's. These various gin-drying systems offer varying levels of drying, and ginners can not easily balance the cost of a drying system against the needs of their gins. This paper compiles the significant dryer developments and research conducted on the drying of seed cotton at cotton gins since 1928. It describes how the various systems use combinations of the basic drying factors (air temperature, air volume, time of exposure, and relative speed of the air and the cotton-slip) to satisfactorily dry cotton. The information and appraisal of the available systems should prove helpful to engineers planning new designs, and to gin owners selecting dryers for their gins.
Technical Abstract: This paper reviews gin dryer designs and compiles most of the significant research conducted on the drying of seed cotton at cotton gins since about 1928. it describes the operation of various types of dryers and gives a critical appraisal of dryer designs that may be useful at current cotton gins. These include the traditional 24-Shelf Tower Dryer, High Volume Tower Dryer, High-Speed Blow Boxes, Fountain and Collider Dryers, Belt Dryer, Hi-Slip Dryer, Turbulent-Flow Hot-Shelf Tower Dryer, Even Heat Tower Dryer, and Vertical Flow Dryer. The compiled information and recommendations should prove useful to scientists planning future gin drying studies, and to engineers selecting dryer designs for commercial gins.
