The Allgaier rolling bed dryer combines the advantages of drum dryer systems and fluidized bed dryer systems and is used to dry wood chips and organic waste. The innovative design behind this dryer makes it possible to dry material uniformly and gently at low temperatures, with the material remaining inside the dryer for a particularly long time and making the dryer ideal for processing organic waste into refuse-derived fuels.
The material layer rests on a perforated plate and has drying air flow into it from below. An agitator continuously circulates the bulk material to ensure that it is thoroughly mixed. The high degree of filling ensures that the drying air will be redirected numerous times before leaving the bulk material, which contributes to a highly efficient transfer of heat and ensures that no moist zones are produced. On top of this, there is no stratification between the hot distribution plate and the top of the bulk material, ensuring that the drying results are uniform and optimal.
Ideal for: Wood chips, green landscaping waste, biowaste, digestates, beet pulp, bagasse, refuse-derived fuels
