NEW CLARIFYING PROCESS.

The Louisiana Planter.-There has
been brought out recently without very
much ado, but with the promise of much
success, new process for clarifying
sugar solutions. This new process
seems to be based largely upon the as.
sumption and possibly upon the fact
that practically all impurities found in
cane juice in the ordinary process of
manufacture are physical impurities
and not in solution To these physical
impurities there attach all manner of
wild yeasts, or ferments, some of which
the ordinary processes Of Qualification
fail to kill. Apart from these, there
| lie in the physical impurities themselves
open Judgment for invasion by ferments
until they are entirely eliminaed. 1t
occurred to George E. Sanford that he
could invent method by which cane
juice could be quickly clarified and
rendered incomparably more stable than
now in its capacity TO resist fermenta-
ton. Proceeding with this idea in
mind, he invented cylinder, or bowl,
made to, rotate with extreme rapidity,
| 400 revolutions minute, and he found
by actual test under the conditions he
had that his method was a success and
as others investigated it, it became APP
parent to them that there was possibly
an eormously wide field for this APP
paratus.
~ AS nearly as we can read between
the lines of the description of the in
venton, the revolving bowl is similar
in way to the revolving bowl of the
standard milk, or cream separators. Ex-
periments began with 24-inch bowl,
but Mr.. Sanford has now settled upon
IL q l. oF > a m
rifaeture. His present view is to have
battery of these bowls say of three
for thousand-ton sugar house. He
1 believes that one of them will handle
500 tons. but would require some time
for its emptying when clogged with re-
fuse. He therefore makes the basis of
a battery of three of this capacity for
a thousand-ton house. giving ample
time to have two machines in constant
use.
The development of this machine
seems to have arisen from the efforts
that Mr.. Sanford and his friends are
making in CoWngton to produce high
grade sugar cane syrups with less
liability to fermentation. The idea was
then conceived of eliminating all physi-
cal trash and rotating sieve CEN
trifugal, or bowl has been finally work
ed out, which does al the work ex-
pected and secures the elimination of
all the impurities, such as particles of
cane leaves. of cane fiber, of cane cells,
of cane wax, of actual earth attached
to the cane and. in fact, of practically
everything that is not in solution This
/ idea is the foundation idea of the new
II movement and experience has led Pres.
J ident Sanford into high expectations OF
the result of his invention on the sugar
, industry in its various phases. AS
practical sugar planters we know that
a sedimentation prevails to greater
or less extent in sugar manufacture
, from the beginning to the end and we
, know also that it is based almost en-
; tirely upon physical impurities that are
