Dryers

Indirect dryers separate the heat source from the material being dried with a metal heat transfer surface Heat sources can be steam, hot oil, or water from the material being dried The material is kept moving over the metal heat transfer surface by an agitator There are several types of indirect dryers.

Belt Dryer

The Haarslev low temperature double pass belt dryer is designed for the gentle drying of wet product such as sewage sludge but can also be used for wood shavings and chips, bark, grasses, leaves, green cut, hulls and husks, litter from animals, fermented residues, marcs and pomaces, bio waste and bio coals and animal faec.

Direct and Indirect Heat Transfer

The direct heat transfer is done by introducing medium pressure steam into the circulation line with direct steam nozzl No heat exchanger is needed due to the small amout of steam required, and at the same time, heat exchanger cleaning or repairing is eliminated The indirect heat transfer is done by shell/tube heat.
