Abstract: A deodorizing device for waste air from hot air treatment plants for foodstuff and/or animal feed, having a treatment unit with a housing which has a treatment chamber that can be flowed through and is arranged between at least one waste air intake connection and at least one waste air outlet connection. At least one capacitor element and an activated carbon filter element are arranged in the cross-section, which can be flowed through. At least one fresh air supply line opens into the treatment chamber, wherein the cross-section of the fresh air supply line that can be flowed through can be changed and/or closed by means of a motor-driven control valve. At least one filter element is also arranged downstream of the opening of the fresh air supply line into the treatment chamber.

Abstract: A continuous-flow treatment system having a heat treatment device for the thermal continuous-flow treatment of solid food and animal feed and other bulk materials, including: a tubular drum having a motor-driven shaft and a drum casing connected to same via spoke elements, wherein the drum is open at the end sides thereof; a screw conveyor attached to the inner side of the drum casing; a housing which can be closed on all sides, in which the drum is rotatably mounted, and which has at least a respective supply opening and discharge opening, wherein of the components forming the drum, at least the drum casing is completely surrounded by the housing; at least one temperature sensor arranged in the drum; and a heating device having a hot air generator and an air distributer with at least one wide-slot nozzle extending up to the drum casing.

Abstract: A method of treating a substance in the form of divided solids, includes the steps of introducing the substance into an enclosure in which there exists an ozonated atmosphere under pressure, conveying the substance in the enclosure with a continuous movement in such a manner that the substance is located continuously in the ozonated atmosphere while it is being conveyed in the enclosure, the substance being conveyed by vibration means causing the enclosure to vibrate, and unloading the substance from the enclosure via the outlet after a single passage of the substance through the enclosure.
