During the year 2008, DSM screen having slot size 0.7mm installed at mill house for screening of mixed juice and DSM screen with slot size 0.35mm working for screening of clear juice were replaced by two rotary screens of 0.5mm slot size for mixed juice and 0.2mm slot size for clear juice. after initial operational difficulties both the screens worked satisfactorily, not only clarity of clear juice increased but bagacillo particle in juices decreased which resulted less scale formation in juice heaters, evaporator tubes and back liner of continuous centrifugal. Also, e-circulation/ overflow of juice at the 2 mills was considerably reduced, resulting in improved mill working.
