Milling

by returning this juice to the cane before it passes into the second mill the 

 amount of fresh water required in the maceration process is reduced. It must 

 be remembered that all the water added to the juice must again be evaporated, 

 and as steam is required for evaporation, it is important to use as little water as 

 possible consistent with the percentage of sugar extracted. 



The juice from the various mills is caught in a shallow metal pan and led 

 to a trough where it is passed over a fine screen to remove all of the small 

 pieces of cane fibre. tiaocioft Ubnucy 



In well-designed modern mills, with cane carrying not over 

 Bagasse \2% fibre, more than 98% of the sugar in the cane is extracted 



and the remainder is left in the fibre of the cane. This fibre or 

 woody part of the cane is known as bagasse and is comparatively dry when it 

 leaves the last set of rollers. In the best milling work the moisture has been 

 reduced as low as 36% of the weight of bagasse. As the fibre comes from the 

 last mill it is conveyed directly to the furnaces underneath the boilers and in a 

 modern raw sugar factory with cane containing HJ/2% fibre, no other fuel 

 than bagasse is required for generating all of the necessary steam to operate 

 the factory. The boiler plant is usually of large capacity and automatic 

 conveyors are employed for the purpose of firing or stoking the boilers. The 

 ashes from the burned bagasse are returned to the fields as fertilizer.
