Traditionally, it can take hours to freeze a mixture of milk, sugar, and other ingredients into ice cream that's ready to eat. The MooBella machine churns it out quickly by spraying a thin layer of the ingredients onto a metal plate. The plate is chilled chill n. 1. A moderate but penetrating coldness. 2. A sensation of coldness, often accompanied by shivering and pallor of the skin. 3. to a temperature below the mixture's freezing point freezing point Temperature at which a liquid becomes a solid. When the pressure surrounding the liquid is increased, the freezing point is raised. The addition of some solids can lower the freezing point of a liquid, a principle used when salt is applied to melt ice on , or the temperature at which a substance changes from a liquid to a solid. That way, the mixture freezes on the plate. MooBella's method also ensures that the treat is soft and creamy cream·y adj. cream·i·er, cream·i·est Rich in or resembling cream. cream  i·ly adv. .

A traditional ice cream maker A domestic ice cream maker or ice cream freezer is a machine used to make small quantities of ice cream at home. Ice cream makers may stir the mixture by hand-cranking or with an electric motor, and may chill the ice cream by using a freezing mixture, by pre-cooling the breaks up growing crystals by mixing the ice cream as it cools. Since MooBella ice cream freezes in an instant, only tiny crystals have time to grow. "Small ice crystals give ice cream a smooth texture," says Bruce Tharp, a dairy scientist and ice-cream industry consultant. |
