  • Overpressure absorption mechanism for fluid bed processors
    Patent number: 9581298
    Abstract: An overpressure absorption mechanism is provided for a fluid bed processor. The mechanism includes spring assemblies mounted in the legs of the processor. The arms of the lower housing section extend into the legs and are supported on the springs. If an overpressure condition arises within the processor, the springs compress to allow movement between the housing sections to allow engagement of clamping rings which contain the over pressure condition.
