The process and equipment, according to this invention, for manufacturing clear, solid ice of spherical and other shapes are capable of making clear ice balls and block ice of other shapes in the mold quickly, efficiently, and with effective energy utilization. This process is characterized in the steps of:a) preparing a mold for making ice balls and block ice of other shapes, which comprises an upper mold (24a) made of an insulating material and provided with a vertical injection hole (23) drilled therein and a water-injection nozzle (22) fitted in the hole; and a lower mold (24b) made of a water-freezing block (26) having coolant pipe (25) embedded therein;b) preparing for a domed lid (21a) or the lid of a different shape made of an insulating sheet, said lid (21a) having a shape that fits in with the surface shaped for the upper mold (24a) and being provided with a cylinder for being fitted into the vertical injection hole (23); and a shaped hemispherical cup (21b) of the same insulating sheet, which similarly fits in with the shaped surface of the lower mold (24b);c) assembling both halves of the mold (24) after the lid (21a) and the cup (21b) have been attached tightly to each other and placed in the mold;d) then, keeping the liquid to be frozen cooled at a predetermined temperature and spraying the liquid intermittently in the direction of the water-freezing block (26) that has been cooled to a predetermined freezing temperature;e) repeating the spraying operation to freeze the sprayed liquid in the container (21), layer by layer, until clear ice balls (20) or block ice of other shapes are formed; andf) disassembling the halves of the mold under the ice-releasing effect, which the ice container (21) has on the ice-making mold (24), and immediately taking out We shaped ice balls (20) or the block ice of a different shape.
