PROBLEM TO BE SOLVED: To reduce the treatment cost by treating sludges of a high water content such as a plating sludge into a sufficiently dry state in a short time at a low cost using a device having a relatively simple structure.SOLUTION: The inside of a drying tank 1 is divided into two upper and lower chambers of an upper tank chamber 1H and a lower tank chamber 1L using a plurality of perforated plates 2 ..., a sludge is loaded in the upper tank chamber 1H, the sludge is dried by sending hot air from the side of the lower tank chamber 1L, and after it is dried, it is dropped into the lower tank chamber 1L by turning the perforated plates 2 ..., and is further discharged downwards by opening bottom plates 1X, 1X. |
