Product Description

The machine has a heated through, containing rotating heated paddle shafts. The specially shaped paddles do not have a transport function but are designed for maximum heat transfer. This results in an excellent control of the temperature of the product and enables a uniform product quality. At the outlet side, the product moves out of the machine via an adjustable overflow.

The Nidhi Evaporation Technology paddle dryer offers a once-through drying technology that avoids back-mixing, which makes the machine very suitable for sludge drying. The long sludge retention time combined with the average sludge temperature of 100º C makes it possible to provide pasteurization and hygienic treatment of sludge – any sludge. Any residual moisture level can be chosen for the end product. This makes the machine suitable for partial drying to 35-40% dry solids, which is required prior to incineration of sludge.
