The National Sugar Insitute in Kanpur has reportedly made a major breakthrough in the processing technique of sugarcane juice clarification. The new process is a high-yielding, faster technique that overcomes the drawbacks of the conventional method, officials said. As per the NSI claims, this 'short-route' processing technique only takes about 35-40 minutes to remove impurities, far more efficiently than the previous method which took about 2 hours and is bound to decrease sugar losses.

The Kanpur NSI centre has developed a smarter means to catalyse the process of sugarcane juice with the help of a specially designed reactor, aerator and floatation clarifier. The technology has been successfully tried in the Experimental Sugar Factor of the institute in collaboration with The Sugar Technologists Association of India and M/s Chemical System Technologies, New Delhi.

Director, National Sugar Institute, Narendra Mohan, said, "In the conventional technology, the precipitated impurities from the sugarcane juice are removed by allowing them to settle in continuous settlers which takes about two hours, resulting in colour development, loss of heat and sugar losses."

"In the developed technology, the impurities are removed through flotation which requires only about 30-45 minutes thus overcoming the drawbacks of the conventional process. We have used a specially designed reactor, aerator and floatation clarifier for the purpose," Mohan added.

He said that the initial trials indicate colour removal during clarification to be much higher-yielding sugar of better quality. Sugar should be taken out of the process by the shortest route as any increase in processing time is bound to increase sugar losses.
