Cookbook:Ice Cream Machine

An ice cream machine or ice cream maker is a piece of equipment that chills and churns an ice cream base mixture into the final frozen product.

Types
All ice cream machines work on the same basic principle. The liquid ice cream base is first transferred to a chilled canister with a paddle. Then, either the canister or the paddle rotates, which churns the ice cream base to keep ice crystals small and incorporate air into the final product.

Power
The power used to rotate the canister or paddle can either come from a motor or by turning a crank by hand.

Cooling mechanism
Three main ways to cool the canister exist. The most traditional method involves packing the canister in a container of ice mixed with salt. A newer method common in household ice cream machines involves a canister whose walls are filled with a coolant solution—this canister needs to be thoroughly pre-frozen in a standard freezer before use. A third method uses a compressor to self-chill the canister and requires only electric power.
