How do you use precipitation to produce sucrose from sugar cane?

Answer 1

Sugar cane is first shredded, then pressed out, and the residues are extracted with water and roller mills. During the crushing, the solids are sprayed with water or diffusion process and the sugar is separated from the plants by dissolving. Milk of lime is then added to the boiling liquid which forms a precipitate with soluble non-sugars. The liquid is then filtered and evaporated. Excess material is skimmed off the top and the liquid is concentrated and allowed to crystallize the sucrose and drain off excess molasses. The mix is added to syrup and boiled a few more times to extract maximum sucrose.
