A method for processing thin stillage (TS), characterized by the following steps: a) feeding of thin stillage (TS) into a working vessel (); b) concentrating of thin stillage (TS) in a filtration unit (); and c) returning of a first substream of concentrated thin stillage to the thin stillage (TSI) present in the working vessel () in order to adjust the solids content, and apparatus for producing a protein-containing product of value.

Method for processing thin stillage and apparatus for producing a protein containing product

A solid-bowl screw centrifuge includes a rotatable drum having a horizontal axis of rotation, which drum surrounds a centrifuging space. Further included is a screw which is arranged within the drum, the screw being rotatable at a different speed relative to the drum. Further included is at least one liquid discharge sealed from its surroundings and at least one solid discharge in a tapering region of the drum. Also included is an immersion disk on the screw which disk lies between a liquid feed and the solid discharge and divides the centrifuging space into a discharge space between the immersion disk and the solid discharge, and a separation space between the immersion disk and the liquid discharge. The centrifuge includes a device for charging the separation space with a gas. A process for operating for the solid-bowl centrifuge is also disclosed.
