Abstract

This paper describes an application of microwave power for the roasting of beans (soybeans, rapeseeds, coffee beans, sunflower seeds, pumpkin seeds, sesame seeds, peanuts and the like) for the sake of destroying the anti-tripsin enzyme (or growth inhibitor) and thus facilitating safe nutritional consumption by humans and animals. A leaky waveguide applicator developed for this purpose is described and analyzed while representative results of bean roasting are presented to illustrate the improvement in efficiency and lowering of cost relative to present techniques.
