the total dose may vary from 1 ppm to 20 ppm and preferable dose is 10 ppm as shown in fig2 the juice obtained from the mill sanitation is heated at about 70 u00b0 c and then neutralized according to the first embodiment to the invention juice can be neutralized by mixing of the lime with the juice i e adding lime to neutralize the acidic juice in the second embodiment of the present invention juice can be neutralized by initially raising ph of the juice to about 7 5 8 0 by mixing lime and then mixing phosphoric acid and or co 2 to neutralize the alkaline juice in the third embodiment according to the present invention the juice can be neutralized by treating the juice first with milk of lime to raise ph above 8 or at desired level and neutralizing the alkaline juice with so 2 by using sulfur burner according to the forth embodiment of the present invention co 2 gas can be used in the third embodiment to neutralize the alkaline juice instead of so 2 to avoid sulfur content in the final product as shown in fig2 the neutralized juice obtained from one of the embodiments of the present invention is heated to about 105 u00b0 c and then is passed through the dorr clarifiers to remove impurities the flocculating agents can be added in the dorr clarifier to increase rate of settling of impurities unwanted solids and the like the overflow from the dorr clarifies is then passed through the series of evaporators to boil off water for further concentration to obtain syrup having about 60 solids afterward the syrup is fed to the crystallizers and pans to obtain sugar which is then separated from mother liquor washed with steam or hot water.
