Abstract
Microwave drying of ceramic honeycomb logs using a customizable cover that can take the form of a flexible wrap or a rigid cover is disclosed. The cover can be in the form of a wrap disposed directly in contact with the leading edge of the log surface. The cover can also be a rigid cover disposed adjacent but not in contact with the leading edge of the log surface. At least a portion of the trailing edge of the log can remain uncovered either by having windows in the wrap or by the rigid cover only covering the leading edge of the log surface. The customizable cover can be configured to compensate for log shape deformities as well as or in addition to the adverse effect on log shape cause by the drying differential created by passing a log through a microwave drying station leading-edge first.
