FIELD: food industry.
SUBSTANCE: installation includes a distillation column (1) and an externally heated reboiler (13) connected to the still (9) of the distillation column (1) and serving for supply of heat to the distillation column. The installation is equipped with a separator for separation of distillery slop into solid substance fraction and liquid fraction; the separator is designed, for example, in the form of a decanter. The reboiler (13) is designed in the form of an evaporating apparatus with a dropping film evaporating at least part of liquid juice fraction and supplying liquid juice fraction after evaporation and/or flash steam produced in the process of evaporation into the still (9) of the distillation column (1).
EFFECT: invention ensures supply of energy into the distillation column at a relative low temperature level without the risk of the reboiler contamination.
