THE EXTRACTION OF JUICE BY MILLS. 



The results so obtained lend themselves to graphic representation. In 

 Fig. 130 is plotted on the horizontal line the total extraction at each point, 

 and on the vertical line the purities and amount of available sugar in the 

 whole quantity of juice extracted. The product of the height of the available 

 sugar curve at any point into the extraction at that point represents the 

 available extraction at that point. 



In no case is there reason to suppose that increasing the extraction will 

 decrease the amount of available sugar due to a lower purity. 



As regards the second conception stated above, local conditions are the 

 dominant determining factor ; the writer's attempt to solve the question was 

 made for conditions as they were in certain factories in Mauritius, circa 1902, 

 and is reproduced below from ' Sugar and the Sugar Cane.' It cannot le too 

 strongly insisted on that those interested should make the calculations themselves, 

 using their oivn choice of data.
