Abstract: Rotor body assemblies for use in a cold temperature cylinder to produce frozen confectionary made from fruit juices or similar liquids. Each assembly comprises a shaft on which are mounted hard plastic blades. The blades may be force fitted within a slot in the shaft, the slot being diagonally oriented from top to bottom with respect to the vertical orientation of each shaft surface. The blades may be formed as one piece with the shaft. Also mounted on the shaft are a conically-shaped top liquid distributor, also of hard food-grade plastic and a bottom ejector of the same material.
