A frustro-conical chamber for separating particles in a fluidized bed for blood component or cell separation. The chamber is characterized by an injection-directing surface for directing inflowing fluid along a frustro-conical wall of the chamber. A dam adjacent the cell-injection port may be circumferentially disposed within the chamber and may have its maximum height adjacent an injection port, and the height may diminish away from the injection port. The injection directing surface may comprise a shelf extending into the interior of the chamber from the injection port, thereby impeding fluid flow in the direction of an outlet port.

A method is provided for controlling separation of solid and liquid phases in a centrifugal basket of a centrifugal. The method includes the steps of monitoring at least associated values of the rotational speed of the centrifugal basket and a purging of the liquid phase from the centrifugal basket, wherein the purging of the liquid phase from the centrifugal basket is monitored using an accelerometer, determining a safe temporal range within which temporal range a wash water can be safely applied to the content of the centrifugal basket, and applying a wash water to the content of the centrifugal basket during at least a portion of the safe temporal range. A computer program product and a centrifugal system are provided for carrying out the method.

Process including the solvent crystallization of edible fatty material into a crystal slurry containing at least solid crystallized stearin dispersed into a solution composed solvent and olein, and further including the separation of the stearin from the solution by applying centrifugal forces onto the crystals slurry.

A system for removing undesirable elements from blood. The system includes a centrifuge bowl to separate the blood into components according to relative densities of the components, a pump to provide wash solution that washes the blood in the centrifuge bowl, and a controller to wash the blood in the centrifuge bowl in a first wash and remove first undesirable elements and to wash the blood in the centrifuge bowl in a second wash and remove trapped undesirable elements. The controller to further mix the blood and the wash solution in the centrifuge bowl and provide diluted blood, separate the diluted blood into concentrated blood and the wash solution, fill the centrifuge bowl with previously concentrated blood to build a buffy coat, and empty the centrifuge bowl of the concentrated blood and the previously concentrated blood after the buffy coat is reached.

Methods and systems for classification and recovery of certain solids from streams, such as liquid waste streams. Methods including classification with at least one solid bowl centrifuge, followed by a valorization procedure. The valorization procedure may be a flotation procedure, which may include a single-step or two-step procedure.
