Abstract

A process for cold clarification of juice is described. A sugar cane or beet juice clarification process to clarify raw juice by means of aeration of fresh raw juice, addition of milk or lime, anionic and/or cationic flocculants, particularly together with a carbonating process, addition of phosphoric acid and then passing the juice through activated carbon bed is described. The process eliminates the need to heat the juice at any stage thus making it more cost effective, energy saving and gives better yield in terms of quality and quantity both. The recycling of defecated, carbonated and phosphated filtered juice and carbonated and phosphated mud that reduces the consumption of lime, CO2 and phosphoric acid up to some extent is described.

Dependent claims

A cold juice clarification process used for sugar cane or beet juice in order to remove colour, turbidity and other impurities, wherein the same comprises steps of:

(i) de-aeration of raw juice under vacuum;
(ii) addition of milk of lime in de-aerated juice for pH adjustment;
(iii) addition of flocculants in de-aerated juice;
(iv) setting and separation of defecated mud from defecated juice;
(v) addition of milk of lime in defecated juice for pH adjustment;
(vi) bubbling of CO2 in defecated juice from step (v);
(vii) addition of flocculants in carbonated juice from step (vi);
(viii) settling and separation of carbonated mud from carbonated juice;
(ix) addition of phosphoric acid in carbonated juice from step (viii);
(x) addition of flocculants in carbonated juice of step (ix);
(xi) settling and separation of phosphated mud from phosphated juice;
(xii) passing phosphated juice through activated carbon bed;
and
(xiii) filtration of juice.
