Btu (British Thermal Unit) is a measure of how much energy an appliance or system uses. One kilowatt hour equals 3413 Btus. You should look for higher ratings for high-volume or thicker products.

Some dipping cabinets, on the other hand, are more affordable than soft serve machines. These dipping freezers require minimal maintenance and use very little power. This can help you save a lot on your utilities. It is easy to train an employee how to properly scoop ice cream and load it into a freezer.
