  • Patent number: 7915458
    Abstract: A method of increasing the yield of oil production in a process of producing bio-ethanol in particularly comprises: creating concentrated syrup as a by-product from an ethanol production, and recovering oil from the concentrated syrup, wherein the step of recovering oil from the concentrated syrup includes using a horizontal axis centrifuge, and wherein the step of using a horizontal axis centrifuge includes using a bowl, a discharge of deoiled syrup and a baffle plate, the baffle plate being located inside of the bowl and retaining oil from the discharge of deoiled syrup.

  • Patent number: 7632094
    Abstract: A method for producing glucose from a starch solution includes a step for saccharification of the starch solution (30) by adding enzymes and/or acid to crude syrup. The method then includes separation of a phase of proteins and/or fats from the crude syrup in a centrifugal separating device (110) and separation of the phase (50) of proteins and/or fats from the centrifugal separating device (110) separately from the residual crude syrup.

  • Patent number: 5972119
    Abstract: In order to obtain starch and proteins from the flour of legumes, in particular peas, the legume flour which has been treated with an aqueous decomposing agent, is fed into a first section (I) of a process line with several solids-liquids separation stages (6, 9, 10) for the purpose of extracting the proteins. The solid phase suspended in water from the final solids-liquids separation stage (10) of the first section (I) is then fed continually into a second section (II) of the process line with at least one separation stage (11) for separating the fibers from the starch and at least one solids-liquids separation stage for separating the starch from the liquid phase. The aqueous decomposing agent is formed from an alkaline concentrate (B) and the liquid phase separated by the starch in the second section of the process line.

  • Patent number: 5618409
    Abstract: The centrifuge (1) described has at least one device (11,12) designed to control the operation of the centrifuge, the devices being mounted to rotate with the rotating part of the centrifuge and to be operated by a mechanical actuator (13) also rotating with it. Such devices may, for instance, be drain valves, periodically opening discharge valves, sill height adjustment devices, pressure-control devices, temperature-control devices, etc. At least one part of the devices of this centrifuge to be controlled independently of the centrifugal force is designed so that the rotating actuator (13) changes its shape as a function of the temperature and has at least one temperature-specific shape.

  • Patent number: 5372260
    Abstract: A scroll-conveyor centrifuge for separating a suspension into at least a liquid phase and solid material which is deposited through centrifugal force on the interior surface of the centrifuge bowl and which is conveyed along that surface to the solid material discharge opening located at an axial end portion of the bowl through rotation of the centrifuge helix at a differential rate with respect to the bowl. Abrasion of the interior bowl surface and operating power requirements due to movement of the solid material in the direction of the bowl circumference are both reduced by the simple expedient of applying to the interior bowl surface a texturing through the spray application of a thin adhering layer having a rough surface facing the helix.

  • Patent number: 5222935
    Abstract: Centrifuge for the separation of a suspension into a solids phase and at least one liquid phase, especially decantering centrifuge with separator following in alignment, full-jacket screw centrifuge or the like with screw (2) rotating at differential speed of rotation from its jacket (1), the helices (4) of which fit close against the course of the inner surface of the jacket, which narrows conically over at least some of its axial section looking toward the solids outlet (13) in particular, and between which, the hub (3) of the screw, and the jacket (1) is left the separation section (6), into which the suspension is injected, especially through a cavity (10 & 11 or 10 & 12) in the hub (3) of the screw.

  • Patent number: 5120298
    Abstract: A decanter for separating a suspension into a solid space and one or more liquid phases, in which a rotatable drum with a screw inside, rests on a machine bed. The screw is rotatable at a speed that is different from the speed of the drum. A transmission is provided between the drum and the screw, and a motor on the bed is connected to the transmission through a torque-transmitter. Intake and outlet lines communicate with the drum to connect the solids and liquid phases. An elastic bearing disengages at least one of the drum, screw, motor, and transmission in at least one direction having a vector component parallel to the axis of rotation of the decanter. The elastic bearing engages the drum, screw and transmission through the attenuator or damper.

  • Patent number: 4957475
    Abstract: Solid-bowl helical centrifuge for separating a suspension, with a stationarily secured intake pipe (31) for supplying the suspension from a stationary infeed point outside the centrifuge to a separation space (3) left between the screw (2) and the bowl (1), whereby, to prevent obstructions due to centrifugal force and malfunctions due to radial displacements and ensure low-maintenance operation, the intake pipe (31) extends into an intake space (32) inside the screw and the end (34) at that location rests against a component (36 and 35, 36 and 38, 36, or 43), which is secured to the screw, by way of a friction bearing (12) with two halves (14 and 15) that are made of a ceramic material where they contact each other.
