Coextrusion device with composit output for making chewing gum with center of gum and shell of sugar

摘要

Co-extruder (6) of a composite sausage (21) having a core (22) of chewing gum (5) with a coating (23) of cooked sugar (4) has 2 conveyors (2,3) which converge in a V-shape towards the co-extruder (6) from which a single stream (7) is fed to a means (8) for forming the sausage (21) into dragees, pastilles or tablets. The co-extruder includes a compression-extrusion head (16) having an extrusion channel (29) inside which is a drawplate (48); and a chamber (51) of a distributor (49) having 2 symmetrical ducts extending via lateral connecting cavities (53) to an extrusion conduit (54) of the drawplate (48).
