jumbo group smart dry GmbH

jumbo group smart dry GmbH, headquartered in Buttenwiesen, Germany, manufactures the SpeedRotation STR dryer series and the PyroDry integrated drying-and-pyrolysis system for sewage sludge, digestate, and biomass treatment. The SpeedRotation STR uses rapidly rotating throwing blades to suspend sludge in a material cloud within the drying chamber, where hot gas at approximately 300C is injected for thermokinetic drying. This approach reduces moisture from roughly 75% down to 10% residual within minutes, requiring just 700 W of thermal energy per liter of water evaporated — near the theoretical physical limit of efficiency. The fully automatic process includes integrated pelletizing via a forced-wheel pelletizer, producing stable, nearly dust-free pellets. The ARC (Active Remote Control) system logs all drive, temperature, and control data every 5 seconds, enabling unmanned 24/7 operation with remote monitoring accessible via PC, tablet, or smartphone. Thermal energy can be sourced from CHP units, micro gas turbines, pyrolysis plants, sludge incineration, or gas and biomass burners, with intelligent control adapting dynamically to fluctuating heat inputs. The PyroDry system pairs the T:CRACKER pyrolysis reactor with the STR dryer for fully energy-self-sufficient operation: the 300C pyrolysis exhaust gas directly drives the drying process with zero external energy input. Extreme pyrolysis temperatures destroy PFAS, microplastics, pharmaceutical residues, pathogens, pesticides, and trihalomethanes, while producing carbonisate (biochar) pellets suitable as activated carbon, compost additive, or soil amendment with plant-available phosphorus that permanently sequesters CO2.
