Abstract: A method of separating albumin from serum by ion exchange chromatography with membrane adsorbers characterized by high productivity and yields of high purity albumin. The separation of the albumin is carried out on highly basic anion exchange membranes and on highly acidic cation exchange membranes. The albumin fraction can be eluted from the anion exchange membrane such that it can be fed directly to the cation exchange membrane without any special conditioning and the albumin can be extracted therefrom as an end product.

Abstract: A device for raking flowable material from a storage facility, with a plurality of storage units such as bunkers, silos, stockpiles, has a bunker table positioned at the bottom of the storage units and a rake tunnel positioned above the bunker table. A raking carriage is positioned in the rake tunnel above the bunker table so as to be moveable in a longitudinal direction of the rake tunnel along the bunker table. A drive unit, including a gear box and a drive shaft, is connected to the raking carriage. A raking wheel is rotatably connected perpendicular to a rotational plane of the raking wheel with the drive shaft to the raking carriage. The bunker table has a longitudinal slot. The raking wheel rakes with two opposite sides the flowable material on the bunker table through the slot of the bunker table onto a continuous conveyor system located under the bunker table.
