Abstract
Abstract Confectionery articles are coated with precrystallized, molten tempered chocolate by forcing the chocolate under pressure through a nozzle onto a veil plate to produce a downwardly descending film of chocolate under gravitational force, passing the confectionery article through said film, collecting unused chocolate and recirculating the unused chocolate through said nozzle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
In a method for coating confectionery articles with a tempered chocolate, comprising the steps of feeding a current of precrystallized, molten tempered chocolate onto a veil plate to produce a downwardly descending substantially pressure-free film of molten chocolate under gravitational force, passing the confectionery articles to be coated through said film, collecting unused chocolate and recirculating said unused chocolate to said current, the improvement consisting of pressurizing said current prior to its being fed to said veil plate to an overpressure of at least one atmosphere and subjecting the current to a brief high shear stress by forcing the current by the aid of said overpressure through at least one nozzle onto said veil plate in said feeding step.
Claim 2
Dependent Claim
119 words
In a method for coating confectionery articles with a tempered chocolate, comprising the steps of feeding a current of precrystallized, molten tempered chocolate onto a veil plate to produce a downwardly descending substantially pressure-free film of molten chocolate under gravitational force, passing the confectionery articles to be coated through said film, collecting unused chocolate and recirculating said unused chocolate to said current, the improvement consisting of pressurizing said current prior to its being fed to said veil plate to an overpressure of at least one atmosphere and subjecting the current to a brief high shear stress by forcing the current by the aid of said overpressure through at least one nozzle onto said veil plate in said feeding step.
Claim 3
Dependent Claim
40 words
The method for coating confectionery articles with a tempered chocolate as in claim 1, wherein the overpressure pressurizing said current prior to its being fed to said veil plate is at least one atmosphere and no greater than three atmospheres.
Claim 4
Dependent Claim
29 words
The method for coating confectionery articles with a tempered chocolate as in claim 1, including maintaining the chocolate under conditions which promote the maintenance of a state of crystallization.
Claim 5
Dependent Claim
28 words
The method for coating confectionery articles with a tempered chocolate as in claim 3, wherein the chocolate is precrystallized to a viscosity which remains substantially constant with time.
Claim 6
Dependent Claim
124 words
The method for coating confectionery articles with a tempered chocolate as in claim 4, in which, to precrystallize the chocolate, the chocolate is heated to a first temperature lying above its highest melting temperature, is cooled down in a first cooling stage to an intermediate temperature of about 30° to about 31° C., then cooled in a second cooling stage to a second temperature of about 28° to 29° C. and thereafter is heated without overheating to a third temperature, the third temperature amounting to about 33° to about 34° C., and in both cooling stages the chocolate is cooled with a cooling medium the temperature of which is only slightly lower than the final temperature of the chocolate in the respective cooling stage.
