Abstract: A frozen confections blending machine, especially for blending basic frozen comestibles with flavors of users' choices, whereby each end product may vary, in quick succession, from a previous one. To perform the therefor required change-over procedure, the subject improvements were introduced, including facilities for rapid, frequent and sanitary cleaning operations between product changes, such as a permanently built-in sink having drainage, protective shieldings against random soilage of the internal machine components and provisions for improved safety of machine operations of those parts which were not rendered safe by the sanitary improvements.
