THE
COMPLETE
PRACTICAL
DISTILLER.
From
1
hectolitre
of
sjrup
you
can
obtain
20
or
24
hectolitres
of
well-fermented
wash,
which
renders
about
80
litres
of
spirits
at
19°
.Beaum6.
This
quantity
differs
from
those
reported
in
various
works
—
some
saying
more
could
be
produced,
and
others,
that
not
so
much
might
bo
looked
for
under
any
circumstances.
The
medium
has
boon
taken
here,
which
is
more
likely
to
be
right
than
either
of
the
extremes
alluded
to.
The
only
way
to
account
for
the
results
so
widely
dif-
fering
is
by
the
admission
of
the
fact,
which
is
very
pro-
bable,
that
by
exhausting
the
molasses
much
more,
it is
rendered
less
fit
for
distillation
;
while
another
operates
on
molasses
richer
in
sut/ar,
less
exhausted,
and
with
a
better
knowledge
of that
particular
kind
of
work.
It
is
necessary
to
observe
that
the
produce
of
spirits
mentioned
before
is
owing
to
the
process
which
has
just
been
de-
scribed
for
fermenting
it.
Moreover,
the
reader
must
be
warned
that
one
of
the
advantages
attached
to
this
method
of
operating
results
from
the
use
of
the
spent-wash.
This
occasions
an
economy
in
fuel,
as
the
caloric
of
the
wash,
leaving
the
still
in
a
boiling
state,
is
in
this
in-
stance
appropriated
to
good
use.
Besides,
there
are
found
in
the
use
of
the
spont-wash
all
the
benefits
which
have
been
before
developed
in
speaking
of
the
transformation
of
sugar
into
alcohol.
It
has
often
been
found
of
advantage
to
put
grain
to
this
mixture,
at
the
rate
of
from
5
to
7
kilogrammes
per
100
litres
of
molasses.
This
grain,
when
broken
and
consist-
ing
of a
mixture
of
20
kilogrammes
of
malt
to
80
of
rye,
gives
more
impetus
to
the
fermentation,
niul
ronJors
it
more
complete.
