Abstract
A food preparation appliance, such as a blending, mixing, or food processing appliance, allows for rotatable blade movement by a drive and/or driven shaft relative to a jar holding contents along with movement of the jar relative to the blade in the axial direction of the drive and/or driven shaft. For example, a vertical or axial movement of the blade relative to the jar, or vice-versa can be guided within defined limits. Aspects provide the consumer with an intuitive and proactive way of preventing cavitation and improving the blending performance by allowing the user to manually and indirectly physically agitate the mixture with an up and down motion of the jar during a blending operation. This option for manual operation is part of the disclosed blender design, so is always and conveniently available to the consumer as an anti-cavitation method.
