A prototype of EHD-enhanced drying system

The performance of an electrohydrodynamically enhanced drying system has been evaluated with its prototype. This scale-up system is the first implementation of such drying technology. It utilizes two convey belts to form a continuous operating system. The prototype uses wire electrodes which are charged at high voltages with positive polarity. The test runs use wet construction sands as sample. The results show that the prototype produces drying enhancement consistent with results previously reported and thus it confirms that the technology can be successfully scaled up. The performance of the prototype can be further enhanced by fine tuning the operating parameters.
