Abstract
A frozen beverage machine includes a mixing block having a plurality of inlets and an outlet coupled to a freezing chamber. The freezing chamber has a drain valve and a dispensing valve coupled thereto. Beverage ingredients are pumped into corresponding ingredient inlets of the mixing block such that the ingredients are mixed in the mixing block to form a product mixture, and the product mixture flows from the mixing block outlet into the freezing chamber. The freezing chamber and the mixing block are refrigerated. The product 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. The cleaning solution is drained from the freezing chamber via the drain valve.
