  • Patent number: 10245598
    Abstract: The invention relates to a method for the operation of a laboratory centrifuge (1), wherein a rotor (2) rotates around a horizontal rotational axis (3). It should be avoided that during the start-up of the laboratory centrifuge (1) or the deceleration of the laboratory centrifuge (1) for small angular velocities and small centrifugal forces resulting therefrom due to the gravitational acceleration the product (6) is biased by resulting components of the acceleration in vertical direction which change their sense of direction. For this purpose the acceleration of the rotor (2) is chosen such that when arriving for the first time in a reversing angular position (twelve o'clock position) there is already a centrifugal acceleration being larger than the gravitational acceleration. The corresponding applies for the deceleration of the rotor after the centrifugation.

  • Patent number: 8956272
    Abstract: The invention is a method of processing tarry or resinous liquids. Tarry liquids include wet scrubber liquids containing tars and chars derived from gasification, pyrolysis or drying of biomass. Resinous liquids include those derived from processing coniferous biomass. Tarry or resinous liquid is processed by a horizontal axis centrifuge having a discharge chamber containing a scraper to prevent centrifuge clogging or fouling. The removed tar and char can be used as solid fuel or recycled to the gasification or pyrolysis process. Polymers, for instance cationic polymers, can be added to the tarry or resin containing liquid prior to centrifugation to assist in solids/liquids separation. Removed resin can be recycled for further use. Tar, char or resin depleted wet scrubber liquid can be recycled for further use or more easily treated prior to disposal.

  • Publication number: 20150045199
    Abstract: The invention relates to a centrifugal separator having a separation space with a set of separation plates, an inlet configured to feed a fluid product to be separated into the separation space, the inlet and the separation space being connected in a pressure mediating manner, a first and a second outlet extending from the separation space for discharge of a two phases of the product. A discharge control system is configured to trigger the opening of the second outlet upon a trigger condition, wherein the discharge control system comprises a sensor arranged to determine the inlet pressure and/or the inlet flow of fluid product, and the trigger condtion is associated with a decrease in inlet flow in relation to inlet pressure, indicating an increasing flow resistance downstream of the inlet. The invention further relates to a discharge control system and a method of controlling the intermittent discharge of a centrifugal separator.

  • Patent number: 8950586
    Abstract: A platelet collection device comprising a centrifugal spin-separator container with a cavity having a longitudinal inner surface. A float in the cavity has a base, a platelet collection surface above the base, an outer surface. The float density is below the density of erythrocytes and above the density of plasma. The platelet collection surface has a position on the float which places it below the level of platelets when the float is suspended in separated blood. During centrifugation, a layer of platelets or buffy coat collects closely adjacent the platelet collection surface. Movement of a float having a density greater than whole blood through the sedimenting erythrocytes releases entrapped platelets, increasing the platelet yield.

  • Publication number: 20150024921
    Abstract: The invention relates to a centrifugal separator comprising a rotor arranged to be rotatable around an axis of rotation (x). An inlet chamber is formed in the rotor and an inlet pipe extends into the rotor and has an opening in the inlet chamber for supply of a liquid mixture of components. An inlet arrangement is provided in the inlet chamber, comprising a set of annular discs coaxial with the rotor and forming passages for liquid between the discs, or a helically shaped element coaxial with the rotor and forming passages for liquid between the windings of the helically shaped element. The separator further comprises vanes arranged upstream of the inlet arrangement such as to cause a pre-rotation and pre-acceleration of the liquid mixture. The vanes may be provided on a removable element of the rotor.

    Abstract: Provided is a blood component separation device that can shorten the overall time to collect high-concentration platelet liquid for blood component donation, thereby reducing time to keep a donor for blood drawing. The blood component separation device includes a temporary storage bag (also used as a buffy coat bag) which is also used as a whole blood bag for storing whole blood drawn from the donor. A control means performs whole blood drawing from the donor in parallel with performing at least either of a circulation flow step and an acceleration step, thereby storing the collected whole blood in the temporary storage bag.

  • Publication number: 20150005149
    Abstract: Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.
