198 BEET ROOT SUGAR. 



draulic press can produce, to obtain all, for the pulp 

 will regain moist. It is a question, whether the last 

 portions of juice are worth the trouble of obtaining 

 them. The first juice runs from the bags without 

 pressure^the second with a light pressure, the third 

 with a heavy pressure ;_ and it remains to be proven, 

 whether the juice obtained by a very heavy pressure, 

 is worth the cost of the labor. The last juice ob- 

 tained cannot be more than eight or ten percent. 

 This would, of course, in a great measure depend 

 upon the power used ; for steam, wind, water, horse, 

 or ox power, are all cheaper than the labor of man, 

 though it is so frequently used, A hydraulic press, 

 of the power of ten tons^will extract seventy per 

 cent, of juice at first ; but when the power is 

 doubled, eight per cent, is about the portion extract- 

 ed, which will not certainly pay for the labor. 



The quantity of syrup to be obtained from a given 

 weight of beets, depends more upon the rasp than 

 the press. The finer they are rasped the more juice 

 i obtained, but all beets do not give the same pro- 

 portion; for it has been found by actual experi- 

 ment, that those beets which contain the most sugar r 

 yield the smallest portion of juice. It is the quanti- 

 ty of water which makes up the superabundance of 

 juice, and so exactly is this pointed out by the areom- 

 eter, that manufacturers can ascertain how much su- 

 gar can be obtained from a given quantity of roots. 

 Thq operation of pressing should be carriecj on %s 

 rapidly as possible*
