Experimental Survey on Microwave Drying of Porous Media

The cost of drying carpet which is done toward the end of the manufacturing process, is quite high. The carpet industry has been using convection drying for many years. Little attention has been given to quantifying the effect of microwave power during the drying of carpet. An experimental system was developed whereby air was introduced into the cavity of a domestic microwave oven. The results indicated that microwave power levels and sample specifications are the most important parameters, with statistically significant effects on the drying constants.
