Abstract
Methods and systems for controlling evaporative drying processes using environmental equivalency control process parameters to provide a specified product quality. In an environmental equivalency-based control system, measured values are received by environmental equivalency calculation hardware or software. An environmental equivalency value is calculated based on the measured parameters. One or more of the process parameters may then be varied to maintain the environmental equivalency value for the process within a predetermined range of environmental equivalency values.
