ABSTRACT:
New and unexpected control is achieved over the ratio of food ice mix/air directed from a food ice mix container to a freezer chamber. A one-way float valve is disposed within the channel between the food mix container and the freezer chamber. Float valve apparatus is operative within the food mix container capable of automatically adjusting the size of a food mix port or aperture extending in fluid communication with the freezer chamber so that as the level of food mix in the food mix container becomes lower, the size of the food mix port becomes larger to maintain a constant flow rate of food ice mix from the food mix container into the freezer chamber. Level indicating apparatus is operatively associated with the float including a vertically movable elongated member extending above a cover on the food mix container such that when the level of the food ice mix drops, the elongated level indicator similarly drops. An air content adjusting member extends downwardly into the freezer chamber operatively connected or integral with a channel extending between the food mix container and the freezer chamber for adjusting the uppermost point of fluid communication between the freezer chamber and the channel, thereby adjusting the ratio of food ice mix to air held in the freezer chamber.
