Abstract: A feature for preventing material buildup in a mixing vessel of a frozen drink maker is described. The feature may include at least one protrusion extending into a vessel chamber of a mixing vessel. The at least one protrusion may be positioned on a central axis of a dasher that is positioned within the vessel chamber and the at least one protrusion may be sized and configured to fit into a space defined by one or more mixing blades of the dasher at a first end of the dasher.

Abstract: An illustrative micro-puree machine is provided. The micro-puree machine includes a base unit including a coupling interface arranged to couple with a detachably connectable processing container. The coupling interface includes a mixing shaft configured to extend into the processing container. A drip tray couplable to the base unit below the processing container when the processing container is coupled to the coupling interface. The drip tray is configured to receive food material that leaks from the processing container while coupled to the coupling interface.

Abstract: An illustrative micro-puree machine is provided. The micro-puree machine includes a detachably connectable processing container including a lid having an opening configured to receive a mixing shaft. The lid includes a blade holder configured to hold a blade assembly to the lid. The blade holder is coupled to a release lever configured to control the blade holder to be disengaged from the blade assembly when the release lever is in a release position. A base unit includes a coupling interface arranged to couple with the lid of the detachably connectable processing container. The coupling interface includes at least a portion of the mixing shaft configured to extend through the lid and into the processing container when the processing container is coupled to the coupling interface. The coupling interface includes at least one radially extending arm forming a corresponding at least one slot, each of the at least one slot including at least one sidewall.
