Abstract: In a commercial ice cube making device, an accelerated freezing and harvest cycle is effected by employing parallel adjacent rectangular channel ways which are individually directly connected to intake and outflow manifolds, thereby producing even absorption and dispersion. In addition, melting of the cubes during the short harvest cycle takes place on one side only thereby reducing the problem of stored ice cubes freezing and sticking together. The ice cubes are made in novel nylon ice trays with combed partitions which allow ice to form from the vertically disposed evaporator outwards on both of its sides. The device advantageously produces large quantities of symmetrical non-sticky ice cubes more quickly and efficiently than the devices known in the prior art.
