Apparatus and process for coating edible receptacles
The present invention provides an apparatus for coating an edible receptacle the apparatus comprising a nozzle for applying a fat-based coating material to the internal surface of the edible receptacle and a gas-dosing element with an external surface shape corresponding to the internal shape of the edible receptacle wherein the gas dosing element has at least one aperture suitable for the introduction of cooled gas into the edible receptacle. The invention also provides a process for manufacturing a coated edible receptacle for a frozen confection comprising the steps of: providing an edible receptacle; at least partially coating the internal surface of the edible receptacle by spraying a fat-based coating onto the internal surface of the edible receptacle; and introducing a gas-dosing element into the edible receptacle, wherein the gas-dosing element has an external surface shape corresponding to the internal shape of the edible receptacle and wherein cooled gas is introduced into the edible receptacle through the gas-dosing element and wherein the gas dosing element does not come into contact with the fat-based coating.
1. A process for manufacturing a coated edible receptacle for a frozen confection comprising the steps of:
providing an edible receptacle,
at least partially coating the internal surface of the edible receptacle by spraying a fat-based coating onto the internal surface of the edible receptacle, and
introducing a gas-dosing element into the edible receptacle
wherein the gas-dosing element has an external surface shape corresponding to the internal shape of the edible receptacle and wherein cooled gas is introduced into the edible receptacle through at least one aperture in the gas-dosing element and wherein the gas dosing element does not come into contact with the fat-based coating.
2. A process according to claim 1 wherein the cooled gas is at a temperature of from −20° C. to −200° C.
3. A process according to claim 1 wherein the edible receptacle is a wafer-based edible receptacle.
4. A process according to claim 1 wherein the edible receptacle is a cone.
5. A process according to claim 1 wherein the edible receptacle is coated with fat-based coating in a total amount of from 2 to 12 g.
6. A process according to claim 1 wherein the weight ratio of the total amount of the fat-based coating relative to the edible receptacle is from 5:1 to 1:5.
7. A process according to claim 1 wherein the fat-based coating is selected from the group comprising of chocolate, chocolate-based compositions, chocolate analogues, and couvertures.
8. A process according to claim 1 wherein the melting point of the fat-based coating is from 20° C. to 50° C.
9. A process according to claim 1 wherein the thickness of the final fat-based coating on the coated edible receptacle is from 0.5 mm to 5 mm.
10. A method for prolonging the crispness of an edible receptacle for a frozen confection, the method comprising the steps of:
providing an edible receptacle,
at least partially coating the edible receptacle by spraying a fat-based coating onto the internal surface of the edible receptacle, and then
introducing cooled gas into the edible receptacle through a gas-dosing element having at least one aperture suitable for the introduction of cooled gas into the edible receptacle and an external surface shape corresponding to the internal shape of the edible receptacle.
