FAQs on PPT - Sugar Manufacturing Process - Chemical Technology - Chemical Engineering

1. What is the main raw material used in the sugar manufacturing process?
Ans. The main raw material used in the sugar manufacturing process is sugarcane. Sugarcane is crushed to extract its juice, which is then processed to obtain sugar.
2. What is the role of chemical engineering in the sugar manufacturing process?
Ans. Chemical engineering plays a crucial role in the sugar manufacturing process. It involves the design, optimization, and operation of various chemical processes and equipment used in sugar production, such as extraction, clarification, evaporation, crystallization, and separation.
3. How is sugar extracted from sugarcane juice?
Ans. Sugar is extracted from sugarcane juice through a series of processes. Firstly, the juice is clarified to remove impurities. Then, it undergoes evaporation to concentrate the sugar content. Subsequently, the concentrated juice is cooled and seeded with sugar crystals to initiate crystallization. The resulting sugar crystals are separated from the liquid through centrifugation, and the remaining liquid is further processed to extract any residual sugar.
4. What by-products are obtained during the sugar manufacturing process?
Ans. The sugar manufacturing process generates various by-products. One of the primary by-products is molasses, which is a viscous dark syrup. Molasses is used as a feed additive for animals and also finds applications in the production of ethanol, rum, and industrial chemicals. Additionally, bagasse, the fibrous residue left after juice extraction, is used as a renewable source of energy in the form of biomass fuel or for the production of paper and board.
5. How is the quality of sugar ensured during the manufacturing process?
Ans. The quality of sugar is ensured through rigorous quality control measures. This includes monitoring the sugar content at different stages of the process, such as juice extraction, evaporation, and crystallization. The sugar crystals are analyzed for purity, color, and size. Any deviations from the desired quality parameters are identified and appropriate adjustments are made to the process parameters to maintain the desired sugar quality.
