As market leader in low-temperature belt dryers, the long-established company from Lower Bavaria continues to set new technology standards in the industry and is thus a decisive step ahead of its competitors. Following of 100 years of tradition, stela Laxhuber has improved its tried-and-tested technology and brought them to the market

The European pellet industry has been waiting a long time for more energy-efficient production facilities, not just in the field of drying. The technicians at stela Laxhuber drying technology took up the topic at an early stage and found a solution that enables energy savings of up to 55 per cent.

An evolution in biomass drying

The stela RecuDry system divides conventional technology into two drying areas. The Recu module saturates the drying air optimally by circulation and reheating. A partial stream of the saturated air is fed to the condensation module. The contained – mostly latent – energy warms the fresh air in the condensation module. By using an air-to-air heat exchanger, a large part of the energy used is thus recovered and thus guarantees a highly efficient drying.

The stela Recu-Dry system – a new technology that makes it possible to retrofit existing plants quickly, space-saving and cost-effectively, while also making a significant contribution to the reduction of emissions in the drying plant.


The steadily increasing number of realized projects in Germany, Latvia, Sweden, Austria, Poland and Slovakia shows the potential of the new technology and continues to make the industry sit up and take notice.
