Filtration Process of Sugar Cane

2. Juice Extraction Use a squeezer to squeeze out the sugar juice from the sugarcane. A certain amount of osmotic water is added during the pressing process to dilute the thicker raw juice in bagasse to extract more sugar. The squeezed mixed sugarcane juice is filtered with a trommel to filter bagasse bran, and then the sugarcane juice is prelimed.
