Flake freezing machine includes an evaporator for producing frozen flakes using a freezable liquid from a liquid source. The evaporator includes a cast aluminum cylindrical structure having an inner surface defining an interior chamber and an outer surface. A stainless steel helical tubing assembly having an inlet and an outlet is embedded inside the cylindrical structure between the inner surface and the outer surface. Refrigerating fluid is circulated through the tubing assembly to cool the inner surface to a temperature sufficient to freeze the liquid. Positioned inside the interior chamber is a rotatable shaft, which supports a liquid distribution pan having radially extending nozzles for distributing the liquid onto the inner surface of the cylindrical structure so as to freeze as a frozen sheet and a blade member for removing the frozen sheet from the inner surface of the cylindrical structure in the form of frozen flakes. A flake freezing system is also provided, which includes the flake freezing machine, as well as an accumulator, a compressor, a condenser, and a heat exchanger. Operation of the flake freezing system is controlled automatically by a controller.
