A distinctive feature of the KAHLfabric belt drier is the special, tightlywoven plastic fabric belt which fulfilstwo functions: Transport of theproduct to be dried and filtration ofthe exhaust air to ensure that thelegal limit value of the dust loadingin the exhaust air is not exceeded.Discontinuous automatic cleaning ofthe belt avoids clogging of the beltopenings.Measurements by independentinstitutions have confirmed theobservation of the limit value. Theaverage value was less than half theadmissible value. Requiring very lowinlet air temperatures of less than120°C, the drier is particularly suitableto be operated with waste heat fromcogeneration. Another advantageis the low concentration of volatileorganic compounds (VOCs) in theexhaust air resulting in very low odouremissions.The newly developed product supplysystem allows the supply of a uniformlayer of product to be dried, even ifthe input material and the throughputcapacities vary significantly. Theproduct is turned over in the drier bymeans of specially adapted devicesso that a very uniform final moisturecontent of the product is obtained.The on-line measurement of theproduct moisture ensures that thedrier is constantly operated with anThe fabric belt drier in a wood pelleting plantoptimum energy consumption andthat the residual moisture is kept ata defined value.Belt widths of 4 m or 6 m are possible.The efficient belt lengths availablefor drying are 11 m to 45 m.
