Brief description of the concentration of a cold liquid, such as a cold, with simultaneous of a fluid other than the said liquid product

摘要

P a process for the concentration of a liquid product, such as a cold, and for simultaneously with a fluid 29 other than the liquid product, such as air, which consists in subjecting said product cold liquid to at least two successive operations of evaporation i, ii, the steam necessary for each operation of evaporation is produced by compression, 18, 23, all or part of the steam produced by this same operation of evaporation, and to use of the steam condensates produced during the one at least, operations of evaporation i, ii, in order to preheat 28 said fluid. & br / b. this process is characterized in that all or part of the condensates 31 obtained after the use of the steam and / or of the condensates to preheat the fluid, possibly mixed with all or part of the condensates remaining from the successive operations of evaporation and to all or part of the condensed steam from the last operation of evaporation, are used for heating 32 the cold liquid to be concentrated 33. & br / c, in particular, in particular, the industry of the milk. / p
