FIELD: technological processes. ^ SUBSTANCE: invention relates to method of ice removal from various ice-containing materials with application of liquefied substance. Method for ice removal in ice-containing material includes stage, at which liquefied substance is brought in contact with ice-containing material, stage, when specified substance, which is gas at normal temperature and pressure, is evaporated, and stage, at which substance is extracted in the form of gas, and liquefaction of specified gas to produce liquefied substance, which is used repeatedly. Ice-containing material represents coal, food product, porous material, organism, biomass or medical agent. Device for ice removal comprises compressor, condenser, water separator, evaporator, separator, expander, degassing column. ^ EFFECT: efficient removal of ice with high extent of extraction in a short period of time, independently on shape of ice contained and its content. ^ 15 cl, 3 dwg, 3 tbl, 3 ex |
