In a process for drying and heating glass batch blend pellets comprising: (a) feeding pellets into a static bed-type dryer; (b) distributing the pellets across the full cross-section of the dryer to form an even cross-sectionally distributed pellet bed of generally uniform height; (c) directing a heating and drying gas into the dryer to dehydrate and heat the pellets; (d) injecting the heating and drying gas at a plurality of preselected bed locations across the cross section of the pellet bed and at a plurality of preselected heights throughout the pellet bed at one or more of said preselected bed locations to maintain a temperature differential between the surface of the solid pellets and the heating and drying gas that is within the range of approximately 20°F. to 120°F.; and (e) removing the heated and dried pellets from the bottom of the pellet bed.
