The present invention relates to a sludge drying apparatus. The sludge drying apparatus comprises: a drying chamber accommodating sludge; a transfer unit transferring the sludge in the drying chamber; and a power unit applying the power to the transfer unit and drying chamber. The transfer unit comprises at least one electrode arranged at preset intervals. When the power is applied to the drying chamber and transfer unit, the current is flowed out to the sludge positioned between the drying chamber and electrode, and among the multiple electrodes, which heats the sludge. Hence, an additional heating device is not required, the energy is reduced by improving the energy efficiency of the sludge drying apparatus. |
