ABSTRACT

After the first extraction operation, a sizable amount of residual sugar was found in the bagasse, according to my investigation at Lugazi Sugar Corporation. To meet the industry’s demand for effective and affordable extraction techniques, this study examined the potential of Modified Single-Pass Imbibition (MSP-I) to improve sugar recovery from sugarcane bagasse. The objective was to maximize sugar extraction while minimizing water usage and evaporation expenses, enhancing process sustainability. The specific goals were to compare MSP-I with conventional single-pass imbibition, analyze the impact of MSP-I on production costs, and determine how well MSP-I improves sugar recovery. Polarimetry, an experimental method that yields precise measurements of sugar content, was used to accomplish these goals. A pilot-scale setup was used in the study to compare MSP-I with conventional single-pass imbibition. The sugar recovery showed a considerable improvement, with an average rise of 29.29% and the same volume of water consumption, according to the results. Moreover, the MSP-I method maintains the evaporation expenses demonstrating significant energy savings. Remarkably, the altered imbibition method showed decreased bagasse moisture content and better juice quality. These results imply that MSP-I is a workable and affordable way to improve sugar recovery from bagasse from sugarcane. The findings are noteworthy because they show how MSP-I can boost productivity, lessen its negative effects on the environment, and boost profitability in the sugar industry. I propose employing MSP-I in sugarcane processing plants, particularly those wanting to enhance sugar extraction while minimizing water and energy use.
