In this first application of the new system to sugar making, it became
a question of ascertaining whether the advantage resulting from
compression was of great importance, and, in the second place, whether
the apparatus could be run with certainty and ease. In truth, the
applications of the system for some years past in other industries
permitted a favorable result to be hoped for, and the result turned out
as was expected.
With this apparatus it has been found that the work furnished by one
kilogramme of steam passing through the motive cylinder, from a
pressure of 5 atmospheres to one of 1.4, is sufficient to compress 2.5
kilogrammes of steam taken from the juice, led into the compressor
at one atmosphere and escaping therefrom at 1.4. In other words, one
kilogramme of motive steam is sufficient to convert into heating steam
for the first evaporator 2.5 kilogrammes of steam taken from the juice
in this same evaporator. Besides, this same kilogramme of motive steam
produces three effects, one in this same evaporator, and the other
two in the two succeeding ones.
