Everything About Ice Cream Maker
Ice cream maker or freezer ice cream is a machine or device that is used when we want to make ice cream at home. These machines use a hand-crank or electric motor for stirring the mixture of materials to produce ice cream because ice cream is smooth and soft, the dough or the ingredients have to keep stirring so as not to form ice crystals. Furthermore, the ice cream should be frozen using a freezing mixture, or with a store in the refrigerator, or by using the freezer that has been provided by the machine itself (like the Musso Ice Cream Maker).
Most ice cream can be eaten immediately after it ready, but some should be retained and further cooled in the freezer to obtain a strong consistency, especially in certain types of ice creams that contain alcohol.

Manual Ice Cream Maker
These kind of ice cream machines usually come with an outer bowl and a smaller inner bowl. There’s a paddle (some called it dasher) on the smaller bowl to stir the mixture by using a hand-cranked mechanism. The outer bowl is filled with a freezing mixture of salt and ice — the addition of salt to the ice causes freezing-point depression; as the salt melts the ice, its heat of fusion allows it to absorb heat from the ice cream mixture, freezing the ice cream.
Since these machines are pretty much do-it-yourself, you can get one for a cheap prive. However, it’s not convenient (you have to turn the paddle by hand every ten minutes or so for a few hours) and kind of messy since the ice and salt mixture will produce a lot of salty water as it melts, which should be remove. Also, the mixture has to be replenished to make a new batch of ice cream.
For your information, the first hand-cracked ice cream model was invented in 1847 by Nancy Johnson. She later sold the patent to William Young, who marketed the machine as the Johnson Patent Ice-Cream Freezer.
