introduction and esrape of the steam, a Uibe for the 

 rising liquid and one to raise the juice. The two 

 first, end on the inside of the top, but the pipe of the 

 latter descends to the bottom of the apparatus. The 

 juice lifter being" full, the tap for the entrance of 

 the liquid is shut olf and steam is introduced, which 

 pressing upon the juice, rapidly raises it by thefluw 

 pipe. 



These marhi'ies by the rapidity and regularity 

 of their working advantageously replace pumps for 

 raising juices an 1 syrups in a fad 



5. BOILERS FOR DKFRflAfl'JNr, AN!) CARUONATATING. 



The juice lifter S3iids the juice into the boilers 

 for defecating. These are four large vessels of sheet 

 iron, nearly cubical. They are furnished witha s team 

 coil for heating and another coil much larger which 

 goes round the bottom and which is pierced through 

 the whole length with small holes, for the purpose 

 of injecting carbonic acid into the liquid. There are 

 also two other boilers for the second earbonatation 

 ,or saturation. 



These boilers are furnished at the bottom with 

 holes closed by taps for ihe escape of the liquid. 



6. DECANTERS. 



These are similar vessels to the preceding, but not 

 so large and without coils, in which the carbonated 

 juice deposits its carbonate of lime and its impurities. 

 The clear juice is decanted and the deposit is sent to 

 filters.
