Industrial Microwave Applications

Industrial microwave applications are rapidly increasing. Their potential in certain areas, the food, rubber and textile industries arises from a combination of advantages: efficient energy conversion, automation and product quality control. Many other heating and drying applications are under consideration today; these include pharmaceutical drying, film drying, and veneer processing. Second and third generation equipment is now in successful use in industry, where applications range from macaroni drying and oyster processing to the rapid heating of institutional lunches; microwave proofing of bread products, for example, has been shown to require as little as one fifth of the energy needed with conventional heating methods. This paper discusses the design and operation of industrial microwave systems and presents some information on evaluating the relative merits of the method from the point of view of the user.
