India is a largest producer of sugarcane in entire world. Our major sugarcane producer states are Uttarpradesh, Maharashtra, Gujarat. In India there are lots of sugar manufacturing unit has setup their plants to produce quality sugar. At present they are producing quality sugar by traditional method i.e. chemical process. Initially sugarcane juice extract by crushing sugarcane in crusher plant. The % of total solids is ranging from 5 to 6%. This sugarcane juice then processed through several steps and finally crystal sugar produced and as by product molasses generated.
During process of producing crystal sugar, initial stage sugar juice contain lot of dissolved and un dissolved impurities. Un dissolved impurities can be removed by passing sugarcane juice through filter press. But dissolved impurities mainly protein, fats, minerals and oil are very difficult to separate from sugar. Traditionally all dissolved impurities are removed by chemical process which is very lengthy and requires maintenance.
