CANE SUGAR. 



Kessler Process. The fossler* mixed process of extraction works 

 on somewhat different lines, and has for its object the extraction of sugar from 

 megass by a continuous process, only one diffuser being used. The apparatus 

 may be described as an upright U-shaped continuous tube, into which megass 

 direct from the mill is fed. Falling into this tube the megass is carried for- 

 ward by a screw conveyer, forced along in a compact mass, and discharged at 

 the other end of the tube. At one end of the tube, opposite to that at which 

 the megass enters, water under pressure is pumped in and travels along the

tube in a direction opposite to that along which the megass moves, and dis- 

 charges at the end the megass enters. After the diffused megass has finally 

 passed through the current of water, it is caught by a screw conveyer which 

 subjects it to considerable pressure and discharges it from the apparatus. The 

 megass after leaving the diffuser is crushed in a mill, and the highly diluted 

 juice thus expressed is returned to the diffuser. This process is illustrated in 

 Fig. 138.
