Device and method for making ice cubes, comprising a supplying device for supplying a liquid substance to at least one elongated mould (1) and a refrigerating device for freezing said liquid substance, which at least one mould defines a space for an ice column which is at least substantially closed at least while said liquid substance is being refrigerated. The at least one mould comprises two mould halves (1a, 1b) which are movable relative to each other, so that the mould halves can be moved apart once the ice column has been formed. Method for making ice cubes, comprising the steps of a) supplying a liquid substance to a mould, b) freezing the liquid substance in the mould, and c) removing the ice cubes thus formed from the mould, wherein the liquid substance is supplied in step a) to a mould comprising an at least substantially closed space. Metering device for ice cubes.

A method and device for reducing ice and frost on a surface comprising a wettable pattern on a surface. The pattern is wetted with water which is frozen into ice to create overlapping hygroscopic that cover the surface.

An automatic spherical ice maker includes an upper stationary ice mold having at least one ice cavity with a hemispherical shape, and a lower rotatable ice mold having at least one ice cavity with a hemispherical shape and corresponding to the ice cavity of the upper stationary ice mold, so that together the at least one ice cavity of the upper stationary ice mold and the at least one cavity of the lower rotatable ice mold form at least one spherical mold which is configured to produce at least one substantially spherical ice ball at a time. The upper stationary ice mold has a first heating element and the lower rotatable ice mold has a second heating element, thereby to facilitate release of the at least one spherical ice ball from the at least one spherical mold.

A cross-connected refrigeration system includes a first refrigeration subsystem and a second refrigeration subsystem that are fluidly coupled by a header, each of the first refrigeration subsystem and the second refrigeration subsystem including a refrigeration loop including a compressor, a condenser, an expansion device, and an evaporator, and a heating loop including an electrically-controlled valve, and the evaporator, and a header connection that connects the refrigeration loops and the heating loops of the first refrigeration subsystem and the second refrigeration subsystem to a common header, respectively. The compressor in the first refrigeration subsystem is selectively deactivated and the electrically-controlled valve in the first refrigeration subsystem is selectively opened such that compressed gas from the compressor in the second refrigeration subsystem enters the heating loop of the first refrigeration subsystem and heats the evaporator of the first refrigeration subsystem.

An ice machine includes a plurality of cooling tubes with each cooling tube having an inner tube and an outer tube extending around the inner tube to define an annular cavity between the inner tube and the outer tube. When refrigerant flows through the annular cavity between the inner tube and the outer tube, water in the inner tube freezes. The ice machine may also include a shell defining an internal cavity through which the plurality of cooling tubes extend; a water source operably connected to a water pump to flow water through the inner tube; a refrigerant source operably connected to a refrigerant pump to flow refrigerant through the annular cavity; and a heater operably connected to the internal cavity of the shell to flow a heated fluid through the internal cavity and across the plurality of cooling tubes.

An ice mold for forming hollow, elongated ice structures intended to be used as drinking straws.
