<p>Apparatus (10) for forming ice blocks or cubes comprising a tray (36) having a series of rows of ice forming compartments or cavities (37), a plurality of ducts (39) arranged between the rows and having a plurality of outlet apertures (43) directed towards opposite walls (44) of the cavities. The ducts (39) communicate with cylinders (21) of compressed refrigerant gases via valves (23) which when actuated communicate the gases with the ducts (39), the rapid expansion of the refrigerant gases and exiting thereof through the apertures (43) causing water in the cavities (37) to freeze and form ice blocks.</p> |
