Sugar manufacturing is an industrial process that converts sugarcane or sugar beet into refined sugar products used in food, beverages, pharmaceuticals, and chemical industries. This process involves extraction, purification, crystallization, drying, and packaging to produce different grades of sugar, including raw sugar, refined sugar, brown sugar, and specialty sugars.
Sugar manufacturing exists to meet global demand for sweeteners and food ingredients while ensuring product quality, safety, and consistency. As food processing and export markets grow, sugar production continues to evolve through automation, energy efficiency, and sustainable practices.
