Ice cream making machine and method which automatically controls the weight of ice cream supplied to containers by increasing or decreasing the amount of overrun, depending upon whether or not the cartons in a production line are overweight or underweight with respect to a desired target weight. Correcting signals are derived at a weighing station which are proportional in time to the amount or underweight of an average group of weighed packages. Such signals are applied to structure which adjust to the amount of air being supplied to the ice cream mix.

A continuous method for the manufacture of packaged ice cream comprising the following steps: (a) Continuously mixing air in a controlled amount with an unfrozen ice cream mix, (b) Continuously delivering the mix to a freezing unit of the continuous type whereby it is incorporated in the mix to produce ice cream with overrun, (c) Continually discharging equal volumes of ice cream into packaging containers, (d) Continually conveying the containers through a weighing station, (e) Weighing the filled containers as they are conveyed through the weighing station and deriving an underweight signal when a predetermined number comprising a group of containers is underweight and an overweight signal when such group is overweight, the durations of the signals being in accordance with the amount of overweight or underweight of the group, and (f) Automatically adjusting the amount of air supplied to the mix responsive to the said underweight or overweight signal, the amount of air incorporated in the mix being increased responsive to overweight signals and decreased responsive to underweight signals whereby the weights of the filled containers are brought to target weight.
