Abstract
This invention discloses a mixing tool for an ice cream maker. The mixing tool is substantially helix-shaped and is disposed within the freezing chamber of an ice cream maker. The mixing tool serves a three-fold purpose. First, the mixing tool scrapes frozen ice cream mixture off of the walls of the freezing chamber. Second, the mixing tool is capable of whipping air into the ice cream mixture if the rate of rotation of the mixing tool is high. Third, the mixing tool urges frozen ice cream toward the dispensing valve of the freezing chamber.
