ABSTRACT:
A process for the production of sugar from either sugar beets or cane wherein of the total amount of thin juice processed, only that amount required to produce the vapor needed for the sugar boiling phase and the desired density of thick juice is directly evaporated while the remainder or excess over and above these requirements is recompressed. Essentially only that fraction of the latent heat of vaporization required for process heating is extracted from the already limited amount of vapor employed in sugar boiling by transferring the heat contained in a portion of this vapor to a refrigerant which is then recompressed so as to raise the temperature thereof to a level of approximately 95.degree. C.
