1. A system for manufacturing clear ice products, the system comprising:
a freezing module comprising:
a frame comprising a plurality of levels arranged vertically;
a plurality of plate freezers, wherein one of the plurality of plate freezers is provided at each level;
a plurality of molds, wherein one of the plurality of molds is provided for placement on each plate freezer and is suitable for receiving water, wherein the mold has a length, a width, and a depth, and wherein the depth is less than each of the length and the width;
a plurality of freeze frames, wherein each of the plurality of freeze frames is configured to receive one of the plurality of molds, and wherein a bottom of each freeze frame is open; and
one or more circulation pumps, wherein the circulation pumps circulate water in the mold to release air bubbles as the water freezes;
a demolding module comprising:
a shelf;
a lift, wherein the lift brings the shelf to a height to remove a mold from a level of the freezing module;
a push/pull mechanism, wherein the push/pull mechanism is used to move the mold from the freezing module onto the shelf; and
a converting station for converting the ice to a clear ice product.
