I once got a tour of a restaurant's ice maker. There was a large, about 3 by 3 feet, sheet of stainless steel. It was at about a 45 degree angle inside the cabinet. It was the surface of the evaporator. water was pumped over it continuously. The water froze forming a sheet of ice on the surface of the plate. It gradually got thicker and thicker and when it was thick enough a sensor triggered the following actions. The compressor stopped and a heater warmed the plate. The sheet of ice slid off onto a series of wires running in the direction the ice sheet slid. These had some electric current flowing through them and quickly cut through the sheet cutting it into long square rods of ice. These then fell onto a second set of wires running in the other direction. This cut the rods into little cubes of ice which then fell into the holding box from which the restaurant workers could scoop out as much ice as they needed at the moment. Because the water flowed continuously there was very little dissolved air which is mainly what makes ice cloudy. The cubes were about a half by a quarter by a quarter inch. Technically not really cubes.
