Mixing paddle for ice cream machine
View Patent ↗A mixing paddle for use in a conventional ice cream maker includes two vertical arms that have outer contact edges that exceed the inner diameter of the freezer bowl in which they are positioned during use. This enables the contact edges to effectively scrape ice cream ingredients from the inner wall of the bowl during use and direct the ingredients toward the center of the bowl. The mixing paddle also comprises two cross-members that have pin-wheel style shapes that move ice cream ingredients vertically during use. The combined effect of the vertical arms and the cross-members optimally and uniformly mixes the ice cream ingredients during use and ensures efficient cooling.
1. A mixing paddle for use with an ice cream maker, said paddle comprising
a top portion of a generally cylindrical shape having open top and bottom ends and an inner wall surface and an outer wall surface;
a first longitudinal arm attached to a lower end of said top portion and extending vertically downwardly and terminating at a distal end, said first longitudinal arm having a first outer edge running vertically substantially along its length, extending radially outwardly with respect to said top portion, and laying in a plane that is tangential to an imaginary circle defined by said top portion's shape, and comprising a first groove running vertically substantially along its length;
a second longitudinal arm attached to a lower end of said top portion and extending vertically downwardly and terminating at a distal end, said second longitudinal arm having a second outer edge running vertically substantially along its length, extending radially outwardly with respect to said top portion, and laying in a plane that is tangential to an imaginary circle defined by said top portion's shape, and comprising a second groove running vertically substantially along its length; and
a first cross-member attached to the respective distal ends of said first and second longitudinal arms, connecting said first and second longitudinal arms to each other.
2. A mixing paddle according to claim 1 , wherein
said first cross-member has a center portion, a first blade portion on one side of the center portion aligned with a first plane, and a second blade portion on the other side of the center portion aligned with a second plane that is not parallel to said first plane.
3. A mixing paddle according to claim 1 , wherein
said paddle is made of plastic.
4. A mixing paddle according to claim 1 , further comprising
a second cross-member attached to said first and second longitudinal arms, connecting said first and second longitudinal arms to each other.
5. A mixing paddle according to claim 4 , wherein
said second cross-member has a center portion, a first blade portion on one side of the center portion aligned with a first plane, and a second blade portion on the other side of the center portion aligned with a second plane that is not parallel to said first plane.
6. A mixing paddle according to claim 1, wherein said top portion is of a generally cylindrical shape and has open top and bottom ends and an inner wall surface and an outer wall surface.
7. A mixing paddle according to claim 6, wherein
said first longitudinal arm lies in a plane that is tangential to an imaginary circle defined by said top portion's shape; and
said second longitudinal arm lies in a plane that is tangential to said imaginary circle defined by said top portion's shape.
