Zusammenfassung:A process for plastically extruding a fat-containing confectionery material e.g. chocolate which comprises feeding the fat-containing confectionery material into an extruder barrel (10) and applying pressure of a piston (11) to the fat-containing confectionery material in a substantially solid or semi-solid non-pourable form upstream of a flow constriction of a die (13) at a temperature at which the fat-containing confectionery material is extruded substantially isothermally and remains in a substantially solid or semi-solid non-pourable form to produce an axially homogeneous extruded product having a cross section that is of substantially the same profile as the die exit of the extruder.
