Process and device for separation of absorbent/floating material from product mixes by means of float/sink separation

A float/sink separation device for separation of absorbent/floating material from product mixes, the absorbent/floating material at least partially saturated with residual fluid, said separation device comprising:

• a vibrating filter for extraction of the residual fluid from absorbent/floating material and producing a filtered product mix;
• a separating tank positioned to receive the filtered product mix from the vibrating filter, the separating tank filled with a liquid separating medium and having a flow generating device creating a surface flow in the separating medium and propelling the absorbent/floating material as a floating fraction from a reception point of the product mix to an output point for the floating fraction, at such a speed that absorption of the separating medium is substantially avoided;
• and
• a mechanism for removal of the separated floating fraction from the separating tank.
