Abstract

The peeling chamber in a head of a centrifuge has an upstream barrier chamber that seals it off from the atmosphere. A barrier disk secured to a peeler extends into the barrier chamber. Compressed gas is supplied to between barrier disk and peeler through a channel to prevent gas from escaping from the solvent. Another channel supplies liquid to the barrier chamber. Solvent from the periphery is supplied to the barrier chamber through a channel and simultaneously by the peeler through the barrier-liquid channel. An area of separation becomes established between the two liquids in the barrier chamber. If any solid particles enter the barrier chamber as the result of gas leaving the solvent, they will dissolve again in the solvent in the periphery of the barrier chamber and will be prevented from making the chamber malfunction.
