An apparatus and method are provided for controlling a frozen carbonated beverage product made by mixing several ingredients (12) in a mixing chamber (18). The apparatus includes a process flow block (16) that controls the flow of the ingredients (12) from ingredient supply sources (24, 28) to the mixing chamber (18). A pair of transducers (144, 156) are provided for measuring the pressure of carbon dioxide and the pressure of the product in the mixing chamber. A pair of solenoids (157, 96) are provided which control the supply of the ingredients into the mixing chamber in response to command signals from a central processing unit (14). The central processing unit (14) instructs the solenoids (157, 96) to open so as to supply the mixing chamber (18) with ingredients when the pressure in the mixing chamber is low and to close ingredients to the mixing chamber (18) when the pressure in the mixing chamber (18) is high.
