REPLACEMENT TO PHOSPHORIC ACID IN PLANTATION WHITE SUGAR MANUFACTURE

摘要

Lime, sulphur and the phosphoric acid are basic chemicals used in the manufacture of plantation white sugar. Phosphoric acid is one of the important chemicals, which plays a vital role in the purification of cane juice in the sugar industry. The sugar produced by this method in India is having sugar colour range in between 55-200 IU by GS2/3-10 method. The sugar colour is one of the most important parameter in export of the plantation white sugar. The present article focuses on the performance trial of a new chemical (replacement to phosphoric acid) conducted at three co-operative sugar factories in Maharashtra for the 2008-09 crushing season.The representative and compositejuice samples are collected and analysed for Brix, Pol, Purity, CaO content, Phophate content, Reducing sugar % and conductivity ash 96, transmittance 96, turbidity and colour. Composite sugar sample is analysed for pol 96, moisture %,reducing sugar, CaO content, conductivity ash 96, Colour, Insoluble matter. The detailed results are given in this article.
