BEET MOLASSES CHROMATOGRAPHIC EXTRACT CRYSTALLIZATION#3 CO-PROCESSING SEPARATOR EXTRACT WITH BEET THICK JUICE

摘要

Difficulty in producing sugar at reasonable production rate and color from separator extract in a 3-boiling crystallization scheme led some companies to employ a practice of continuous co-processing (continuous recycle) of extract with beet thick juice. This was really not a new concept as the, now defunct, lime basedSteffens (molasses de-sugarization) process was carried out on a similar continuous recycle basis. The main difference in the two recycle schemes is that with the Steffens process the continuous recycle was interrupted at regular intervals so that impurities that accumulated as a result of recycle could be purged from the recycle loop.This routine "discard" practice is not normally employed with continuous recycle of separator extract to a sugar end processing beet thick juice.
