  • Patent number: 11882965
    Abstract: A micro puree machine has a mixing shaft attachable to a blade that is subject to both linear and rotational movement. A drive motor is contained within a lower portion of the machine housing and operatively couples to a first gear that engages a second gear on the mixing shaft for rotation of the mixing blade. A position motor within the upper housing operates to move the mixing blade linearly to engage the ingredients in the bowl. During both axial and rotational movement of the mixing shaft, the drive motor and the position motor remain stationary within their respective positions in the housing.
