In addition to the construction of biomass power plants and biomass boilers, we are specialists in the production of wood chip drying systems.
With our wood chip drying technology, the energy yield of the fuel can be significantly increased. Drying systems from Spanner Re² not only reduce the water content of the wood chips, it also minimise the fine fraction and mineral pollutions by integrated sieve elements. This means that you can refine almost any natural wood or wood wastes into a high-quality fuel. The processed material is optimally matched to the requirements of the biomass power plant and ensures a particularly efficient wood gasification operation.
We offer various wood chip drying technologies - from fully automated wood chip dryers to simple wood chip drying systems with sloping ground dryer.

Spanner Re² sloping ground dryer - flexible and cost-effective
With the sloping floor dryer, the wood chips are distributed over a large area on an angled floor (angle approx. 40° to 45°). The slanted floor consists of air-permeable metal sheets.
The warm air flows through the air slits of the sheets from below, drying the wood chips above. The warm air can either be taken from the installation room of the wood gasifier system or generated by a heat exchanger. The heat exchanger can also be operated manually and, in the ideal case, is only switched on during the cold season (assuming that the sloping floor is directly connected to the plant room). The wood chips are distributed on the inclined floor with a front loader or wheel loader, for example. In the course of the drying process, wet wood chips can be re-layered from the bottom to the top or dry wood chips can be transported to a storage bunker for storage.
The sloping ground dryer is a particularly cost-effective type of wood chip drying technology and it has more space available for storage and drying. Depending on the customer's request, the wood chips can also be removed via a screw conveyor.
