  • Deviation ring for a self-distributing centrifuge
    Patent number: 7204795
    Abstract: The invention relates to a deviation ring for paste comprising an annular rebound wall (2) for a self-distributing centrifuge (1). The invention also relates to a corresponding self-distributing centrifuge (1). In the deviation ring, the angle of incidence ? of the tangents of the rebound wall (2) of the deviation ring (4), opposite the distribution slit (3) of the centrifuge (1), in relation to the horizontal, is between 3 and 60° over the entire opening width of the distribution slit (3).

  • Method for the separation of blood plasma particles from a blood plasma suspension
    Patent number: 7081082
    Abstract: Method for separating blood plasma particles from a blood plasma suspension in a self-discharging centrifuge having two or more discharge slits and axially stacked baffle plates, in which the blood plasma particles are separated from the liquid phase by centrifuging and removal of the liquid phase, suctioning off liquid remaining in the drum after separation of the blood plasma particles and discharging the sediment of solid blood plasma particles from the drum by centrifugal force into a collecting container underneath the drum, the drum and the blood plasma sediment being cooled during one or more of the process steps.
