The drum of 340 mm diameter and 420 mm length was fabricated using SS sheet. Body is fabricated in dismantling type 1-inch square SS tube with a suitable covering in the electrical parts. Inside the drum, perforated SS sheet is fitted with suitable projections to remove the scale, and the drum is provided with a leak proof door with suitable lock.
