  • Patent number: 6470595
    Abstract: A process and a device for continuously drying protein-containing sludge, in particular sewage sludge, in a fluidised bed (20) inside a drying container (13). A drying gas flows through the fluidised bed (20) while partially de-watered sludge (6) in granulate form (21) is added to the fluidised bed (20) while dried sludge (10) is withdrawn therefrom. The granules (21) are formed without admixture of dried substances and are granulated preferably at the same time as they are pressed. Sewage sludge may thus be dried without admixture or recycling of dried substances, so that a highly efficient plant is obtained. In addition, a granulated dry material is produced which may be used in various ways.

  • Patent number: 6438867
    Abstract: In a process for drying microporous, fluid-containing particles, the heat required for increasing the temperature is supplied by convection by reducing the interfacial tension of the fluid, preferably to 0 to 1/10, in particular to 0 to 1/20, of the interfacial tension of the fluid at room temperature, by appropriately increasing the temperature at from close to the critical pressure to supercritical pressure of the fluid. Furthermore, microporous, three-dimensionally networked particles are prepared by a process in which the drying process is used. In addition, an apparatus is used for carrying out the drying process, the apparatus comprising a pressure container having an inner container and pressure-withstanding outer container and suitable measuring and control apparatuses and pump apparatuses and heat exchangers, the inner container being provided for holding the particles to be dried and a gap being provided between the inner container and the outer container.
