Ice Cream Machines

Ice cream is a desert made from dairy products combined with flavorings and sweeteners and this mixture is stirred while cooling to avoid the formation of ice crystals. During the early years when there were no refrigerators, ice creams were made by hand in a large bowl surrounded by packed ice and salt. The temperature of the ingredients was reduced by the mixture of crushed ice and salt, which made the production of ice cream possible avoiding the requirement of continuous chilling that, is possible by refrigeration. Now-a-days the most common method of making ice creams is with the help of ice cream machines, an electrical device that churns the ice cream mixture while cooled inside a household freezer or using ice and salt. There are two types of ice cream machines manual and electrical. The manual ice cream machine has an inner bowl with hand cracked mechanism which turns paddle to stir the mixture and sits in the larger outer bowl which is filled with the ice and salt mixture which provides the cooling power. These machines are inexpensive. There are three different types of electric ice cream machines; the difference is in the cooling processes of these machines. Counter top machines use double walled bowl which contains coolant between them, these machines take twenty to thirty minutes to make one batch at a time, are less expensive. Small freezer unit machines sit inside the freezer section of the refrigerators and operate in slow motion; such machines do not require pre freezing of the appliance. The third type of electric machines has their own built-in mini freezer, it does not require any pre planning, and batch after batch of ice cream can be made in twenty to thirty minutes.
