Summary:Methods of reducing transient temperature variations in a microwave drying process for drying partially dried ceramic logs are disclosed. The methods include sending the logs through an output microwave dryer having multiple applicators, each applicator being capable of generating an adjustable amount of microwave power. A transient drying model is employed based on microwave-drying process parameters to determine a predicted log exit temperature at the output end of the output microwave dryer. The exit temperature of each log is measured. The transient drying model, which is used to control the amount of microwave power applied, is adjusted based on a difference between the predicted and measured log exit temperatures.
