Description
Summary:This paper describes an experimental heat pump batch particulate dryer which has been combined with radio frequency (rf) energy, the latter being operated in a continuous pulsed mode. The results show several improvements resulting from the combination drying process. A simplified mathematical model of the dryer, including the rf heating source has been developed using mass and energy conservation, which show good agreement with experimental results.
