Ice cream or water ice mix is filled into moulds and frozen to produce stick novelties.
Weight and cholesterol watchers were delighted. The storage life of ice cream depends on the type of product, the packaging, and maintenance of a constant low temperature. The layer of frozen mix on the inside cylinder wall is continuously scraped off by the rotating dasher knife, and a second gear pump drives the ice cream forward either to an ingredient feeder or a filling machine.The output temperature is -8 to -3°C depending on the type of ice cream product, where 30 to 55% of the water is frozen into ice crystals depending on the composition of the mix formulation.
