Process and apparatus for the manufacture of a frozen product
A filling means for filling an edible cone with a frozen confection comprising: a tubular housing which surrounds and is coaxial with a piston; the piston having a longitudinal passage which has an outlet at the lower end and an inlet at the upper end; and means for supplying the frozen confection to the inlet of the longitudinal passage of the piston, wherein the tubular housing has an outlet at the lower end which is a nozzle having vertical slits and the outlet of the longitudinal passage of the piston is a nozzle having a rounded aperture and wherein the piston is longitudinally movable within the tubular housing such that when the piston is seated within the tubular housing the piston covers the vertical slits, and when the piston is raised within the tubular housing the vertical slits are uncovered is provided. Also provided is a process for the production of a composite frozen product comprising the steps of: Providing an edible cone; Coating the internal surface of the cone with a fat-based coating; Filling the cone with a frozen confection; and then Adding a further portion of a frozen confection onto the frozen confection in the filled cone characterized in that step c) is carried out using a nozzle which has a rounded aperture and in that step d) is carried out using a nozzle which has an aperture capable of forming a fluted shape.
1. A filling means for filling an edible cone with a frozen confection comprising:
a tubular housing 1 which surrounds and is coaxial with a piston 2 ;
the piston 2 having a longitudinal passage 3 which has an outlet 4 and an inlet 5 ; and
means for supplying the frozen confection to the inlet 5 of the longitudinal passage 3 of the piston 2 wherein
the tubular housing 1 has an outlet 6 at the lower end which is a nozzle having vertical slits 7 and
the outlet 4 of the longitudinal passage 3 of the piston 2 is a nozzle having a rounded aperture and wherein the piston 2 is longitudinally movable within the tubular housing 1 such that
when the piston 2 is seated within the tubular housing 1 the piston 2 covers the vertical slits 7 , and
when the piston 2 is raised within the tubular housing 1 the vertical slits 7 are uncovered.
2. A process for the production of a composite frozen product using the filling means of claim 1 comprising the steps of:
a) providing an edible cone;
b) coating the internal surface of the cone with a fat-based coating;
c) filling the cone with a frozen confection; and then
d) adding a further portion of a frozen confection onto the frozen confection in the filled cone;
characterized in that step c) is carried out using the filling means wherein piston 2 is seated within the tubular housing 1 thereby covering the vertical slits 7 and in that step d) is carried out using the filling means wherein the piston 2 is raised within the tubular housing 1 thereby uncovering vertical slits 7 .
3. A process according to claim 2 wherein the nozzle used in step c) has a circular aperture.
4. A process according to claim 2 wherein the nozzle used in step d) comprises an aperture having slits radiating from the outlet of the nozzle.
5. A process according to claim 2 wherein the nozzle used in step d) has a star-shaped aperture.
6. A process according to claim 2 wherein the coating in step b) is achieved by spraying the fat-based coating onto the internal surface of the cone.
7. A process according to claim 2 wherein the frozen confection is an ice cream.
8. A process according to claim 2 wherein step c) takes place less than 5 seconds, less than 3 seconds, less than 2 seconds, less than 1 second, or less than 0.5 second after step b).
9. A filling means according to claim 1 wherein the outlet 6 at the lower end of the tubular housing 1 is in the form of a nozzle having a star-shaped aperture.
