ABSTRACT:
Method and apparatus for producing frozen product characterized by flowing liquid substantially uniformly over a substantially vertically oriented freezing mold; supplying liquid refrigerant to a conductive surface in the freezing mold for freezing the liquid into predetermined shapes; collecting the excess liquid into a reservoir and circulating the excess liquid back over the top of the freezing mold, the liquid being at its freezing point; stopping the circulation of the liquid over the freezing mold and initiating a dump mode in which the freezing mold is heated and tilted to dump the frozen product into a receiving bin; detecting when the receiving bin has sufficient frozen product therein and stopping the production of more frozen product until some has been used; repeating the cycle orienting the freezing mold substantially vertically and starting the refrigeration equipment to freeze the product and repeat the cycle. The preferred embodiment include controls responsive to sensory inputs, deflection plate for deflecting the frozen product into the bin, inclined trough drain to stationary reservoir, insert for freezing easily broken tails between cubes and a special bin.
