Abstract

The present invention concerns an apparatus and a method for producing ice confection comprising mold cavities arranged on lamellae disposed in an endless belt along which are arranged process means for the production of the ice confection by conveying the lamellae between the process means, wherein the apparatus comprises an uneven number of lamellae and the process means are arranged along the belt in such a way, that the ice confection production process may be completed by two full circulations of one lamella on the belt. Due to the uneven number of lamellae a specific lamella will change stop position for each circulation. Hereby, a number of advantages are obtained through an optimal utilization of the lower lamella sequence, such that the shortest possible apparatus is obtained.

Claims

1. An apparatus for producing ice confection comprising:

mould cavities arranged on lamellae disposed in an endless belt along which are arranged process means for the production of the ice confection by conveying the lamellae between the process means,

wherein the apparatus comprises an uneven number of rows of mould cavities, such as the lamellae disposed in an endless belt, and the process means are arranged along the belt in such a way, that the ice confection production process may be completed by two full revolutions of a specific mould cavity on the belt.

2. An apparatus according to claim 1, wherein there is provided one common process means for pre-cooling empty moulds, cooling of a chocolate shell, cooling of an ice cream and cooling of chocolate, said process means comprising a cooling zone preferably extending over at least an area corresponding to two lamellae on the belt in both an upper and lower sequence.

3. An apparatus according to claim 1, wherein process means for chocolate filling into the cavities and chocolate filling on a top face of ice cream are arranged in a same area along an upper belt sequence.

4. An apparatus according to claim 1, wherein process means for the removal are arranged in a same area along the lower belt sequence.

5. An apparatus according to claim 1, wherein the lamellae in the belt, for each process cycle, are conveyed stepwise two lamellae or rows of mould cavities at a time.

6. An apparatus according to claim 1, wherein the lamellae in the belt, for each process cycle, are conveyed continuously two lamellae or rows of mould cavities at a time.

7. An apparatus according to claim 1, wherein process means for pre-cooling of the mould cavities by means of liquid nitrogen are arranged.

10. An apparatus according to claim 4, wherein said process means for removal comprises means for emptying surplus chocolate after a part of the chocolate has solidified to a shell and for removing surplus chocolate on a top face of ice cream.

8. A method for producing a covered ice cream product, comprising:

production of a cover shell in mould cavities on a lamella,

filling of said shell with ice cream, which after freezing is applied a cover layer melting together with the cover shell,

said method being completed by movement of a number of lamellae arranged in an endless belt, whereby the individual lamella is moved between process means disposed along said belt,

wherein the belt comprises an uneven number of rows of mould cavities, such as the lamellae disposed in an endless belt, and the production process of the ice cream product in the mould cavities in a lamella is completed by two full circulations of a specific mould cavity, the belt being conveyed stepwise two lamellae at a time or continuously at an even speed, whereby two rows of mould cavities are conveyed for each function cycle of the production processes.

9. A method according to claim 8, wherein application of a low temperature ice cream of approximately −

8 to −

15°

C. for filling of the ice cream is utilised.
