ABSTRACT:
Ice making apparatus includes a plate forming a plurality of through openings, the plate having an under surface facing downwardly, a plurality of evaporator tips projecting downwardly from said openings, said tips consisting of heat conductive metal; there being downwardly tapering thermal isolators surrounding the tips proximate the plate, first means for supplying refrigerant fluid to extract heat upwardly from at least some of the tips and thereby cool them to ice forming temperature, and second means to spray water onto the under surface of the plate to drain down said isolators onto the tips, whereby ice progressively forms on the tips, and the tips may be subsequently heated to effect release of the ice from the tips to drop downwardly, for harvesting.
