METHOD OF PRODUCING ICE BLOCKS Russian patent published in 2017 - IPC F25C1/22 

FIELD: construction.

SUBSTANCE: method of obtaining blocks of ice includes placing water in the ice-box, placing the ice mould in a freezer in which the temperature is kept below the freezing point of water until it freezes in ice-form. Freezing of ice in the ice-form leads from the bottom upwards, with the supply of cold through the bottom of the ice-form, while the temperature of the water above the frozen ice layer keeps rising from the bottom upwards from the temperature corresponding to the freezing point of water to a level higher than its freezing temperature.

EFFECT: elimination of volume-surface freezing of a sample of ice during its freezing and obtaining a uniform density of ice in the entire volume of the sample, without the use of special ice generators.
