  • POWDER DRYING SYSTEM WITH IMPROVED INLET ARRANGEMENT TO THE FILTER UNIT AND METHOD OF OPERATING THE FILTER UNIT OF SUCH A SYSTEM
    Publication number: 20210131733
    Abstract: The powder drying system comprises a powder processing unit (1), and a filter unit (400) defining a central vertical axis (405) and including a filtering chamber (401) accommodating a plurality of bag filters (407), each having a bag filter wall and a top opening, a top portion (402), and an exhaust chamber (403) at or near the top portion (402). The filtering chamber (401) is provided with an inlet (410) configured to allow entry of powder carrying gas to be filtered, and the exhaust chamber (403) has an outlet (420) configured to allow exhaust of filtered gas. In the filtering chamber (401), gas flows through the wall of the bag filters (407), upwards and out through the top opening of the bag filters (407), into the exhaust chamber (403) and further to the outlet (420).

  • Method for cleaning a nozzle arrangement in a spray drying apparatus, and spray drying apparatus for carrying out the method
    Patent number: 10443933
    Abstract: In a spray drying apparatus, comprising in a usual manner a drying chamber, an air disperser, and at least one pressure nozzle arrangement (4), means are provided for emptying the feed in the nozzle arrangement(s) (4) after the supply of feed from a feed system (5) is halted and before the nozzle arrangement(s) (4) are removed from the drying chamber and positioned in a cleaning system (7). The emptying takes place while maintaining atomization in the nozzle arrangement (4). The feed emptying system (6) comprises a pump (60), a pressurized air/gas source (61) and a conduit (62), and the spray drying apparatus at least one valve (45, 53, 63, 64, 65, 66) allowing switching from the feed system (5) to the feed emptying system (6).
