Abstract
A frozen beverage machine includes a process control block having a plurality of inlets for receiving ingredients and a plurality of outlets. A mixing block has a plurality of inlets connected to the process control block outlets such that ingredients flowing through the mixing block are mixed together therein. At least one freezing chamber is connected to the mixing block outlet to receive the mixed ingredients therefrom, and a refrigeration system is arranged to refrigerate the freezing chamber. A dispensing valve and a drain valve are connected to the freezing chamber. A controller is connected to the process control block to control operation of the frozen beverage machine. The beverage machine includes an automated sanitizing system operated by the controller, in which the beverage mixture is drained from the freezing chamber via the drain valve, and a cleaning solution is pumped into a cleaning solution inlet of the mixing block and into the freezing chamber to sanitize the machine. The cleaning solution is then drained from the freezing chamber via the drain valve.
