MANUFACTURE OF BEET ROUT SUGAR. 



'^ 



The details that I have given on some of the prin-

 of beet root sugar, and the descriptions given of the 

 chief machinery in use, allow me to pass rapidly 

 over the manufacture itself. 



I. EXTRACTING THE JUICE. 



The beets are brought and placed as required in 

 the washers. The workmen entrusted with this fluty 

 should carefully reject all beets that are spoiled, or 

 those that, having been frost bitten are thawed; as 

 those beets contain principles that might ruijn the 

 whole work. They should also avoid allowing any 

 hard substance to pass into the washer. 



The rotary action of the washing drum plf uged 

 one third in water, causes the beets to rub against 

 each other and against the walls of the machine and 

 they are thus cleaned from the adhering eartl). The 

 beets arrive at the other end of the washej clean 

 and are thrown on the grating of the inclined plane 

 where they drain, and get rid of the small|stones 

 that may have come through with them. Tn& beets 

 are then sent against the grater, against which they 

 are shoved by two pushers. The grater reduce^ them 

 10 a fine pulp which falls into the vessels below.
