Rotary drum dryers for biomass products

Industrial rotary drum dryers vary dramatically depending on whether they are directly or indirectly heated. There are multiple ways to heat directly-heated drum dryers and they are extremely efficient and robust. They are primarily suited to wood chips, OSB strands and other biomass products and are heated through different energy systems and burners.

Indirectly heated drum dryers, which are very efficient and robust, are ideally suited to wood flakes, fine bulk solids and also to free-flowing biomass products. They have been developed with cogeneration systems for combination heating and are indirectly heated with steam, hot water or thermal oil, for which Büttner also offers energy technology solutions.
