How Does a Soft Serve Ice
Cream Machine Work
By J.D. Chi, eHow Contributor
The Machine
Soft-serve ice cream,
also known as creemee in some New England states, is processed ice cream prepared
in a specialty machine. The ice cream is served through a spigot at the bottom
of the machine. Individual flavors are poured through each spigot, but in some
cases the machine may be able to make a "twist," which combines two
flavors. Commercial soft-serve machines are large, stainless steel appliances
specifically designed to properly mix and distribute the ice cream. Machines
must be cleaned daily with hot water to avoid contamination.
Soft -Serve Mix
Soft-serve mix comes in several varieties, including
liquid and powder forms. The ultra heat-treated liquid mix is considered the
safest and most consistent mix, as it is heat-treated, sterilized and sealed
and may be stored without refrigeration.
This liquid mix may be used right from the package without any additional
ingredients. It should be cooled to just above freezing for best results. A
powdered mix is considered the second-most reliable mix, because it is simply a
dried version of the liquid mix. Water must be added to the powdered mix. However,
it is impossible to create a consistent product from one location to the next
with a powdered mix, as water quality differs. A fresh liquid mix is also
available and may be stored at cold temperatures for up to 1 week. The danger
in using a fresh liquid mix is keeping it properly cooled to avoid
contamination. Soft-serve mix is available in chocolate and vanilla flavors.
Other flavors are created by adding syrups that are preloaded into the machine
and mixed with vanilla when a particular lever is pulled.
Soft Serve Around the World
Soft-serve ice cream
is available around the world and, in fact, is said to have been developed in
the U.K., where it was marketed as "Mr. Whippy." In Asian countries,
soft-serve is often referred to as "soft cream." In the U.S., the
most popular soft-serve outlets are Dairy Queen, which serves a proprietary mix
and offers chocolate dipped cones, Tastee Freeze, Fosters Freeze and Carvel.
Frozen yogurt may also be prepared and served in a soft-serve ice cream machine.
