Abstract: “EVAPORATOR OF VINASSE CONCENTRATION FOR DISTILLERIES IN GENERAL”, it is applied preferentially in the distillery (1) of ethanol, whose constituent equipments allow the accomplishment of vinasse concentration process (2) using caisson (T1) of evaporation as “reboiler” of the columns (C1 and C2), as well as caisson (T2) of evaporation as condenser of the mentioned columns (C1 and C2), without extra consumption of energy or vapor (3) and water (4), for that using bombs (5) for movement of the product; pre-heaters (not represented) for the heating of the wine (6); final heater (not represented) which accomplishes the last heating of the wine; column (C1) responsible for the first distillation; caissons (T) which execute the evaporation of vinasse; separators (S) that dissociate the vapors of the liquids in the evaporator; column (C2) responsible for the second distillation; evaporative condenser (7) that condenses the vapors of the last effects and system of air removal (8) of equipment by means of vacuous.
