Abstract A twin cavity microwave applicator is described for the final drying of foam backed tufted carpets. The performance of the twin cavity applicator as part of a conventional system, comprising of a conventional hot air chamber followed by the twin cavity dryer, is fully studied in terms of drying foam backed carpets from moisture content values of about 20% down to equilibrium values. The efficiency of coupling the microwave energy into the cavities, the applicator efficiency and the ability of moisture levelling are quantitatively established. The economics of incorporating such a microwave resonant dryer, in multiple twin cavity units, as a final dryer in an industrial carpet printing line are considered in terms of increased throughput.
