ABSTRACT:
A soft serve ice cream dispensing apparatus includes a tank, a closure plate having an integrally formed dispensing chamber and a recirculation passageway and a dispensing valve. When the dispensing valve is closed, the recirculation passageway is not in communication with the dispensing chamber. This allows the apparatus to recirculate ice cream without causing it to flow through the dispensing chamber. During recirculation, the ice cream is recirculated in an open loop consisting of the recirculation passageway, a hollow tube and the tank. The hollow tube is in flow communication with the recirculation chamber, formed in the closure plate, and the interior of the tank and extends approximpately one-third of the distance into the tank. An important aspect of the invention relates to the simplicity and reduced number of parts of the recirculation system which significantly facilitates cleaning. Another important aspect of the invention relates to the fact that the recirculation loop does not include the dispensing valve chamber which greatly reduces liquefaction of the ice cream.
