Whether “more performance” is defined as greater line speed, less energy consumption, or higher throughput efficiency, there are a number of improvements and/or adjustments that can be made to an existing dryer to achieve these objectives. The primary variables of drying temperature, cross-machine temperature profile, air impingement velocity and air volume are reviewed as to how they influence drying performance and how they can be manipulated to improve the drying quantity and/or quality of any hot air impingement dryer.
