Ice Cream Churner Machine

Ice-cream makers are household appliances that turn a basic liquid base or custard – a mixture of cream, milk, egg yolks and sugar, plus any flavourings – into frozen ice cream through a process of chilling and churning. A rotating paddle keeps the liquid moving and lets in air, while also scraping down the sides.In the machine's churn (a container with chilled walls and a mixing paddle), the mixture is stirred as it freezes until it's as thick as softly whipped cream. During churning, air is incorporated, which increases the overall volume of the ice cream. The inflated volume is called overrun.
