Abstract: A freezing barrel with mixing and refrigerating apparatus associated therewith has an inlet at one end to receive a prepared mix to be frozen and has a spigot at the other end for dispensing the ice cream. The prepared ice cream mix is supplied from a reservoir having a float controlled uniform rate of flow to the freezing barrel in each operation. The float is supported on a hollow open ended stem slidable in an upright tubular support and an opening is provided in the stem for gravity constant pressure flow of the mix thereinto as ice cream is drawn off through the spigot. Flow through the opening is controlled by a novel valve such that the rate of such flow is equal to or slightly more than the freezing and mixing capacity of the freezing barrel. The upper end of the stem is open to atmosphere through the valve to admit air into the mix.
