MANUFACTURE 133 



tedious ; it is sufficient for the reader to know that 

 after the most elaborate precautions have been taken 

 the nib still contains about one per cent, of shell, and 

 that the nib obtained is only 78.5 per cent, of the 

 weight of raw beans originally taken. Most of the 

 larger makers of cocoa produce nib containing less than 

 two per cent, of shell, a standard which can only be 

 maintained by continuous vigilance. 



CACAO GRINDING. 



A battery of horizontal grinding mills, by which the cacao nibs 

 are ground to paste (Messrs. Cadbury Bros., Bournville.) 



The shell, the only waste material of any importance 

 produced in a chocolate factory, goes straight into 

 sacks ready for sale. The pure cacao nibs (once an 

 important article of commerce) proceed to the blenders 

 and thence to the grinding mill. 



(g) Blending. 



We have seen that the beans are roasted separately 

 according to their kind and country so as to develop 

 in each its characteristic flavour. The pure nib is now 

 blended in proportions which are carefully chosen to 

 attain the result desired.
