Sugar refiners are companies or facilities that process raw sugar into refined sugar products. They take sugar cane or sugar beets, which are harvested and then crushed to extract the juice. This juice is then purified, evaporated, and crystallized to produce granulated sugar, which is commonly used in cooking and baking. The refining process involves several steps, including filtration, boiling, and drying. The end products can vary, including white sugar, brown sugar, and powdered sugar. Sugar refiners play a crucial role in the food industry, supplying sugar to manufacturers, restaurants, and consumers for various culinary uses.
