Description

technical field

[0001] The invention relates to the technical field of sugar cane sugar production, in particular to a multi-objective optimization method for intermittent sugar cane boiled sugar crystallization process. Background technique

[0002] The purpose of optimizing the crystallization process of intermittent sugarcane boiling is to obtain ideal crystal size distribution parameters, which are important indicators for evaluating product quality and affect the effectiveness of downstream operations. The crystal size distribution parameters mainly include the average crystal size and the coefficient of variation of crystal size.

[0003] As the most important link in the sugarcane sugar production process, the intermittent sugarcane boiled sugar crystallization process is mainly realized by optimizing the massecuite temperature curve in the early stage. Another relatively ideal optimization method starts from the supersaturation of the sugar solution. The higher the ...
