An inefficient drying system at a fuel-pellet manufacturer has been replaced with low-temperature belt dryers from Stela Laxhuber, Massing, Germany.

The belt dryer, operating with low calorific heat, will produce homogeneous and energy-saving dry sawdust at Graanul Invest in Tallinn, Estonia. The band dryers are mounted on a closed subspace, which allows cleaning of the web belt in the winter months by a high pressure washer.

The system dries pellets for use as a biofuel, and the pellets are used as a source of renewable energy. To produce the pellets, wood pulp (sawdust, flinders and split wood) is first crushed, then dried, ground to reach the condition of wood dust, pressed and finally cooled.
