Electro-technologies for post-production processing in agriculture, food and bio-energy

Electro-technologies such as microwave (MW) and radio-frequency (RF) heating systems have the potential for widespread applications in processes that require heat such as in the drying and thermal treatment of produce. These technologies are faster and more energy efficient than conventional methods. Their use will therefore shorten exposure time to heat and can give end-products with better quality. Dielectric heating systems are powered by electricity and do not directly contribute to the production of greenhouse gases. The long-term goal of the proposed research program is to develop new applications and to promote the use of MW and RF heating in the post-production processing of produce for food and for biofuel production. However, until now, the complexity of the design process and the lack of adequate control systems have limited industrial utilization of dielectric heating systems. To achieve the long-term goal, these issues must be addressed.
