VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG VON RINGFÖRMIGEN NAHRUNGSMITTELN

摘要

Food products in the shape of a ring are new. They are produced by extruding a mass of food paste through an annular opening into a tubular shape then cutting it into rings. The foodstuff used can be: (a) a mix based on chopped meat, fish and/or vegetables; or (b) an iced cream and/or sorbet; with a binder. Also claimed is a device for the preparation of the ring-shaped food products comprising the extrusion in two parallel cylinders fed alternately by a rotating pump positioned between them. Each cylinder contains a coaxial shaft, broader at the base to define the extrusion annulus. The tubular extrusions are cut into rings by shutters which alternately operated in synchronisation with the pump.
