ABSTRACT:
A process is provided for utilizing the waste heat content of condensate and/or vapor produced in the manufacture of sugar in which thin juice is cooled, subjected to one or more stages of flash evaporation to concentrate and further cool the juice, after which it is heated with condensate and/or vapor produced elsewhere in the sugar manufacturing process and with incoming thin juice thereby heating the outgoing juice to substantially its original temperature and providing the cooling of the incoming thin juice. In another embodiment completely purified thin juice is concentrated in a multiple effect evaporating plant wherein the vapor produced in the final evaporator is compressed and is returned selectively to one of the preceding evaporators of the evaporating plant for use in heating the juice.
