Abstract: An apparatus for blending and for making ice cream includes drive, blending, and stirring units. The drive unit includes a high-speed output gear unit driven rotatably by a drive shaft and formed with a first engaging hole that extends along a rotary axis, a speed-reduction gear unit driven rotatably by the drive shaft, and a low-speed output gear unit driven rotatably by the speed-reduction gear unit and formed with a second engaging hole that is coaxial with the first engaging hole. The blending unit engages removably the first engaging hole and is driven by the drive unit to rotate about the rotary axis at a higher speed. The stirring unit engages removably the second engaging hole and is driven by the drive unit to rotate about the rotary axis at a lower speed.
