“…Известны различные способы включения обработки экстрактов в технологическую схему производства, и модуль дешугаризации мелассы (ДМ) следует оптимизировать в соответствии с этой интеграцией [10]. Поскольку цветность экстракта значительно выше, чем у сиропа, кристаллизация экстракта по стандартной трехкристаллизационной схеме может быть неэффективной из-за высокой цветности белого сахара.…”

When processing sugar beets, the final waste is formed - molasses containing sucrose and other compounds. Under the conditions of traditional technology, further extraction of sucrose from molasses is difficult. The technology of deep processing of molasses using chromatographic separation (desugarization) has been developed and implemented, which allows additional extraction of sucrose. The resulting extract requires further processing at sugar factories. This article is devoted to the choice of a method for processing the extract under the conditions of sugar production. Various options for processing the extract are considered: after the completion of the processing of sugar beet and during the joint processing of beet and extract. You can send molasses to a desugarization station once, work with a partial return of molasses, or carry out continuous processing of molasses obtained in the crystallization department of a sugar refinery by desugarization. Each processing option has its own advantages and disadvantages. The performed numerical analysis shows that processing the extract with a second pass stage will lead to the maximum total sugar recovery. The second most efficient is endless recycling. An improvement over endless recycling in the molasses recycling process is achieved by optimizing the separator settings due to the consistent quality of the processed feed. Endless processing leads to the accumulation of non-sugars, which destabilizes the quality of the molasses and makes it difficult to set up the separator.
