The stray field which exists around a pair of electrodes consisting of a series of parallel copper tubes set in one plane and energized by means of a radio-frequency oscillator is used to dry tablet granulations. The equipment used and the procedure followed in this investigation are outlined. Data presented include the peak radio-frequency voltages, the power used, the maximum temperatures attained, the rate of drying, and the percentages of water removed from the various chemicals in the form of tablet granulations.
