The obsolete plate / frame type filter process for muddy juice filtration were eventually replaced by rotary vacuum filter where bagacillo is essentially required to be added to work as a filtering media and which long stayed in the sugar industry almost for last sixty years!, inspite of various associated problems; perhaps for the reason of simplicity and more importantly for the reason that better alternative technology was not readily available.
The solid bowl decanter technology has gained wide application for solid-liquid separation in other industries like oil, dairy, chemical, water and sewage treatment etc. and is in existence for more than a century all over the world.
The decanter is now a well proven technology for sugar industry which has great potential.
No bagacillo required
No vacuum requirement
Less power consumption
Less quantity of reject cake
Less sugar loss through reject cake (Pol in reject cake % cane 0.02 to 0.04)
Easy for operation
Higher solid removal of more than 90%
Less moisture content of reject cake (67-70%)
Less maintenance cost
It gives us immense pleasure to inform you that our well proven two stage decanter system at following 12 sugar factories; the highest nos. in India as well as in the world, is indeed a great technological breakthrough and a major land mark in sugar industry world over.
