Patent DE-2018173-A1 (DE)
Title: Chocolate fondant fill extruder
IPC: A23G3/02
Filed: 1970-04-16
Abstract: Fondant filling for chocolate creams is extruded when fed by rolls from a bin into a housing enclosing a screw which forces the mass down towards a template at the outlet end, and so out via a slicer onto an offtaker belt. The end of the housing, i.e. outlet, is heated by resistance coils with thermostat control to melt the layer building up inside close to the outlet and so maintain steady, regular outflow and prevent clogging. Overheating is thus avoided, and temperature conditions are optimised both inside the screw housing and for the chocolate cases etc. awaiting filling at the outlet.
