Abstract

The invention relates to a system for controlling the purification of juice in a sugar mill. The sugar mill includes pre heating unit, liming unit, sulphitation unit and post heating unit. The system of the invention comprises at least one local process controller for controlling one or more control variables that are associated influentially or interdependently thereupon for the control of the sucrose content of the said juice so as to conserve the sucrose content and enhance the colour of the juice, through the control of manipulated variables corresponding to the said control variables. The said control variables being temperature of the juice in the said preheating unit, pH of the juice in the said liming, unit, pH of the juice in the said sulphitation unit and temperature of the juice in the post heating unit, and therewith corresponds to the said manipulated variables that being flow of steam, flow of lime, flow of sulphur dioxide and flow of steam respectively. The system also comprising a central process controller for providing set points for the said control variables purporting to the said local process controllers, by using the process variables and / or process condition data relating to one or more of the said units and thereupon determine the said set points for the said at least one local process controller. The invention also relate to a method for controlling the purification of the juice using the system of the invention.
