Abstract
The machine dispenses a ready-made milk shake. A freezing chamber has a dispensing valve having porting and a valve element so arranged that flow of the semi-frozen comestible and the flavoring material occurs simultaneously. A beater mixes the two during dispensing. A conduit for the flavoring material has a unique coupling to the valve block and a quick-release coupling intermediate its ends. Upon release of the latter, a manually operable sampling valve may be connected to the conduit to selectively draw a sample of the flavoring. A pump is provided for sucking in a liquid comestible and gas in a preselected proportion and delivering them to the bottom of the freezing chamber. A vent is located in the valve block to vent air from the freezing chamber upon start-up of the machine. The vent has an inlet located at a level so that the liquid and gas volumes in the chamber are about equal to the respective proportions pumped.
