Abstract: A method and a system for producing articles of fat-containing, chocolate mass in a continuous production-plant having a conveyor for mould elements with mould cavities. The production-plant comprises steps of initially filling mould cavities with liquid mass, cooling of the articles, and releasing the articles from the mould cavities. The number of mould elements per unit time leaving the cooling step is regulated to deviate from the number of mould elements per unit time entering the cooling step. The resulting advantage is that it is possible to regulate the residence time for a certain mould element in a cooling step without changing the residence time in the steps prior to the cooling step. A manufacturer of chocolate articles is thereby provided an easy way of adapting the cooling time to the specific article being produced without influencing other steps of production.
