Optimization of Parameters of Brix, Flow Rate and Temperature in the Process of Raw Sugar Syrup Decolorization by Ozonation

Removing sugar color is one of the most important goals of raw sugar refineries. Also, color and ash have the most important effect on the quality of crystallized sugar. In order to produce high quality products, every year, a lot of equipment and operating costs and spend for the remove of the color and ash in every sugar mill and refinery. The quality of sugar depends on the quality of the sugar syrup that is produced from it, so the effective refine process, which has the ability to produce bright syrup with a low amount of color, is necessary in the sugar industry. In this research, Treatments of Brix in three level (40, 50 and 60), syrup Flow rate in three level (4, 6 and 8 ) and the Temperature in three level (40, 50 and 60 °C) were considered and color, Invert, pH, ash and purity were measured according to ICUMSA methods and based on the efficacy of each treatments in decoloration and also according to the characteristics of the syrup, optimization was done by the surface response method. The model offered by response surface for the responses of color, pH, Invert sugar, and purity were significant and it was found that the use of ozone in important parameters in the sugar industry includes a reduction in color has a positive effect and on other parameters such as ash, pH, Invert Sugar, and purity have very little effect. The optimal treatment introduced by the model was temperature 43 °C, flow rate 4.2 and the Brix 54, and it was found that no significant effect between amount of specified by software and experimental samples(p>0.05) and optimization points specifiedtruly.
