Process and apparatus for manufacture of a co-extruded iced confection

A process for manufacturing a frozen confectionery product comprising:

• extruding frozen confectionery material through a first nozzle member tube to obtain a first extrudate product which extends vertically downward from the tube and so that the first product has, with respect to the vertical extent of the first extrudate product, an outer surface cross-section shape which comprises an arc portion and a tangent portion wherein the arc portion extends from the tangent portion and comprises, with reference to the tangent portion, two semi-circular portions of differing diameter connected by the tangent portion;
• delivering the first extrudate product from the first nozzle member tube to a product outlet delivery tube member which comprises a cylindrical interior wall about a hollow via at least one further nozzle member tube and with respect to each further nozzle member tube, introducing the first product and additional frozen confectionery material within the further tube and extruding a product comprising the additional frozen confectionery material and the first product vertically downward so that a successively layered product is obtained wherein each successive layer has, with respect to the vertical extent of the layered product, an outer surface cross-section shape which comprises an arc portion and a tangent portion wherein the arc portion extends from the tangent portion and comprises, with reference to the tangent portion, two semi-circular portions of differing diameter connected by the tangent portion and so that each successive layer is positioned to form a spiral shape;
• and
• introducing further frozen confectionery into the product outlet delivery tube member and extruding the further frozen confectionery and the layered product so that the layered product cross-section outer surface is contained within further extrudate which has a circular cross-section shape.
