Radio Frequency
The Macrowave radio frequency (RF) drying system heats filter cake material uniformly to remove water without overheating. The drying system is a suitable replacement for tumble, spray, tray, spin flash and belt/tunnel dryers, and can reduce labor and energy costs by up to 60%, according to the manufacturer. The Macrowave applies energy to filter cake material in the form of RF waves at a frequency of 40.68 MHz. The equipment features volumetric heating, which provides rapid and uniform heating to prevent overheating. The system is available in both batch and conveyorized configurations. — Radio Frequency Co. Inc., Millis, Mass.
