The properties of microwaves and infrared
Webb6 okt. 2016 · Dielectric properties of fresh and processed samples were also detected. It was observed that an increase in microwave power resulted in an increase in rate of drying and a decrease in processing time. It was also found that combining infrared with microwaves resulted in higher rates of moisture loss from the product. http://www.diva-portal.org/smash/get/diva2:830407/FULLTEXT01.pdf
