Type of article: Article


The calculation of the freezing time of foodstuffs during the initial freezing period, where nitrogen vapour with a highly variable temperature is used, is difficult. The article shows that the universally-recognized method of logarithmic averaging of the temperature difference is only correct in the case of the small-surface heat transfer coefficient. More correct formulae for freezing time, taking into account the variation of the refrigeration medium, are suggested.
