Model Optimizes Drying of Wet Sheets

Paper, tea, tobacco, and other food and industrial goods use drying tunnels to remove moisture from wet product sheets during manufacture. The tunnels operate using a fan to supply drying air to the product sheet through an orifice plate. Unfortunately, under some supply conditions, little or no drying occurs. However, by running the tunnels under optimized conditions, one drying tunnel can save up to 10% of the cost of power alone. Inventory control benefits can add to the savings. A model has been created that determines the settings necessary to achieve these optimum conditions.
