Abstract

A method and apparatus for molding and fast chilling food products, preferably confectionery products. The method involves sequentially depositing a solidifiable food substance into one or molds that are part of a plurality of molds radially attached to a chilled roller while the molds are in a substantially horizontal position. The chilled roller is then rotated to move the one or more molds filled with the food substance into contact with a conveyor belt sufficiently soon after the solidifiable food substance is deposited in the molds so as to avoid the exterior surface of the food substance from becoming distorted when the molds move away from the horizontal. The chilled roller at least partly solidifies the food substance in the molds. The at least partially solidified food substance is then separated from the molds onto the conveyor belt. A second method involves sequentially depositing a solidifiable food substance into one or molds that are part of a plurality of molds radially attached to a chilled roller while the molds are in a substantially horizontal position and lowering a chilled plate onto the molds while the solidifiable food substance is being deposited into the mold. The chilled plate contacts the solidifiable food substance to at least partially solidify the exterior surface of the food substance. The chilled roller at least partly solidifies the food substance in the molds. The chilled plate is then removed from the surface of the molds, the molds are rotated, and the partially solidified food substance is separated from the molds.

Claims

1. A food product molding apparatus comprising:

a chilled roller;

a plurality of molds attached radially to the surface of the chilled roller;

a depositor for sequentially depositing a solidifiable food substance into one or more of the molds when the molds are in a substantially horizontal position to provide one or more molds filled with a food substance having an exterior surface;

a conveyor belt arranged to contact the exterior surface of the food substance in the molds sufficiently soon after the solidifiable food substance is deposited into the molds to prevent the exterior surface of the food substance from being distorted as the molds move away from the horizontal position; and

means for separating the food substance from the molds, wherein the temperature of the chilled roller is sufficiently low to at least partially solidify the solidifiable food substance before it is separated from the mold.

2. The apparatus of claim 1, wherein the conveyor belt is arranged to contact the exterior surface of the food substance before the molds have moved more than 90 degrees with respect to their position during depositing.

3. The apparatus of claim 2, wherein the conveyor belt is arranged to contact the exterior surface of the food substance before the molds have moved more than 60 degrees with respect to their position during depositing.

4. The apparatus of claim 1, wherein the conveyor belt remains in contact with the exterior surface of the food substance during an angular motion of the molds of at least 90 degrees before the food substance is separated from the molds.

5. The apparatus of claim 4, wherein the conveyor belt remains in contact with the exterior surface of the food substance during an angular motion of the molds of at least 120 degrees before the food substance is separated from the molds.

6. The apparatus of claim 1, wherein the means for separating the at least partially solidifed food substance comprises introducing compressed air into a cavity behind each mold or introducing compressed air through air nozzles at the bottom of each mold.

7. The apparatus of claim 1, wherein the roller is chilled to maintain a temperature of between about 5°

C. and −

25°

C.

8. The apparatus of claims 1, wherein the molds can be removed from the chilled roller.

9. A method of molding a food product comprising:

sequentially depositing a solidifiable food substance into one or more of a plurality of molds that are attached radially to a chilled roller while the molds are in a substantially horizontal position to provide one or more molds filled with the food substance having an exterior surface wherein the temperature of the roller is sufficiently low to at least partly solidify the food substance;

rotating the chilled roller to move the one or more filled molds from the substantially horizontal position so that the exterior surface of the food substance contacts a conveyor belt sufficiently soon after the food substance is deposited in the mold to prevent the exterior surface of the food substance from being distorted as the molds moves away from the substantially horizontal position; and

separating the at least partly solidifed food substance from the molds onto the conveyor belt.

10. The method of claim 9, wherein separating the at least partly solidified food substance from the molds comprises introducing compressed air into a cavity behind each mold or introducing compressed air through air nozzles at the bottom of each mold.

11. The method of claim 9, wherein the roller is chilled to maintain a temperature of between about 5°

C. and −

25°

C.

12. The method of claim 9, wherein the food substance is a high-boiled sugar, a chocolate, or a fat-based confection.
