Titel
Application of soft-computing techniques in optimisation and control of complex processes in sugar industry
Abstract
This paper presents particular improvements to sugar processing through integrating computing technology. Three aspects were analysed and optimised. Although each facet can be applied independently, they are presented as a whole. First, an improved non-BPE (boiling point elevation) measurement model for supersaturation of the massecuite is presented. Second, the degree of supersaturation is used as the primary reference value for a new batch pan feed control. This feed control loop, based on fuzzy logic, allows to avoid false grain, thus eliminating most reprocessing needs. Feed control is interconnected with other fuzzy control loops for evaporation, steam, and vacuum. Finally, a three-phase batch pan boiling cycle, which helps to avoid conglomeration while effecting optimal crystal growth even when pans must be switched, is described in detail.
