Abstract

A machine for making ice cream or other frozen comestible from a liquid. The machine includes an outer housing in which is inserted a removable freezing chamber which can be independently frozen and replaced in the chamber. Internally of the freezing chamber is a compartment in which can be placed a rotary assembly including a plurality of radially extending blades rotatable with the compartment. The blades include slits at their outer edges defining fingers for atomizing, aerating and moving the frozen liquid through the freezing chamber to its outlet. The blades are of a hard, elastic, low friction material with the outer tips of their fingers lying on an outer diameter larger than the inner diameter of the freezing compartment. The blades are then stressed when inserted into the freezing chamber to forceably engage the inner cylindrical surface of the freezing chamber and are twisted like a helix towards the outlet of the freezing chamber. A presetable control is provided in the top cover of a storage compartment in which the liquid freezing the machine is stored. The control is used to adjust the feed rate of the liquid into the freezing chamber independently of the viscosity of the liquid. An air pump can be included for injecting air under superatmospheric pressure into the freezing chamber as well as a liquid pump for injecting the liquid under superatmospheric pressure into the freezing chamber.
