  • Patent number: 8844162
    Abstract: A device for removing fluids from particulate materials, including a container having a circular process chamber with a cylindrical external contour, an input device for inputting the materials into the process chamber, a discharge device for discharging the particulate materials freed of the fluid from the process chamber, a feed device for feeding a fluidizing agent from below into the process chamber, and at least one conditioning device for conditioning the fluidization agent in the direction of flow prior to the feed device.
    Type: Grant
    Filed: July 14, 2009
    Date of Patent: September 30, 2014
    Assignee: BMA Braunschweigische Maschinenbauanstalt AG

  • Publication number: 20100126034
    Abstract: The invention relates to an appliance (1) for the removal of fluids and/or solids from a mixture of particulate materials with a container (2) that constitutes a ring-shaped processing space (20) with a cylindrical outer contour with devices for the charging and discharging of the particulate material into and out of the processing space (20) and with a fan device (5) for supplying a fluidization agent from underneath into the processing space (20) as well as devices (6) for the processing of the fluidization agent in the flow direction in front of the fan device, whereby in the processing space (20) cells (15, 16, 17) are formed extending in the vertical direction, where one cell constitutes a discharge cell (17) through which there is no fluidization agent flow from underneath, where at the lower end of the discharge cell the discharge device is arranged, and where another cell (15) is provided with a charge device, and where the cells (15, 16, 17) are open at their upper ends in order to enable the transpo

  • Publication number: 20080189976
    Abstract: This invention relates to a process and an appliance for drying byproducts from the processing of starch-containing and sugar-containing raw materials, in particular, after their fermentation and distillation, where the byproduct is fractionated in a purification phase with a high liquid proportion and a thick phase, whereby the thick phase is shaped into particles in a conditioning procedure and whereby these particles are dried in a fluidized-bed drying system with a relative gap volume, in the fluidized-bed layer, between 0.5 and 0.92.
