It
is being operated at present with complete success at the salt works of
France and Switzerland, at those of Austria and Prussia, in the sugar
of milk factories of France and Switzerland, and, finally, in 1882, the
first application of it in the sugar industry was made at Pohrlitz, in
Moravia.
The saving of fuel that has been made in these different applications
has always been great.
We shall now, for the sake of explaining the system, give a brief
description of the apparatus as used at the Pohrlitz sugar works
mentioned above. These works treat 255 tons of beets per 24 hours, and
obtain 4,000 hectoliters of juice, which is reduced to about 1,000
hectoliters of sirup. Up to the present, the concentration has been
effected in a double acting apparatus partly supplied by exhaust steam
from the motive engines and partly by steam coming directly from the
generators.
In order to diminish the consumption of direct steam, these sugar works
put in a Weibel-Piccard apparatus designed to concentrate only a third
of their juice, or about 1,350 hectoliters per day.
