NEW SUGAR MACHINERY.
(GlasgO,O Herold.)

the loss of saccharine per ION or cane pro
duced must be hailed by the planter and con-
sumner alike with satisfaction. 1t Is Well
known that with the present machinery
adopted for crushing, the results aA fr from
satisfactory and so much is this the case that
planters hess ate laying down extra mlllS. No'-
withstanding this. it is f'%pd, utter passing
the cane through three separate mtllS there
is still a loss of something like 10 to 10 per
cent. The fibre averages II per cent? or the
total weight, leaving So pe6cent OF juice
The best results that can be at present "o-
tanned by milling is from IS to Is per &c. ~
S8-78, equal to 10 per cent. OF loss, whlch
if recovered would result as clear pt"ht 10
the planters, who have not hesltated 10 SPehd
large sums of money in introducing addition
al rlant endeavouring to recover TINS loss.
This extraction of rs per cent. has been OBJ
tanned by means of a process IN milling known
as maceration, which consists III the lhtroooc-
ton of water between the mills Although
planters are able to secure a larger percent
age of sugar by this system, the cost Oh the
fuel necessary to evaporate the large qoah'l-
ty Of water added to the juice makes TINS VS.
tenn costly and unsatisfactory. A new machine
has been designed and patented by MT;
Drummond that has succeeded III several
trials made at Govan in extracting $40 per
cent of iuiceo out Of cane that had been cnt
for over two months, The megaSse when
analysed by DR.. Clark, City of Glasgow ANA
lyst. contained OF PEI cent Of sugar. Inns
machine is a new departure, and is unlike
any of the machines now in use. The mod"S
Operandi is as follows:-The cane is cut INTO
lengths Of from four to five inches by q
scotching machine specially designed for this
purpose. Underneath this machine is an end
less band lifting the cut cane into a magazine.
The crushing machine is self contained, ana
stands on a wooden platform foundation. 1t
consists Of three cylinders. The bottom one
is the crushing cylinder, into which the cane
in the magazine is discharged. In the bottom
Of this cylinder is a perforated alr-uSht
piston deep enough to form a cham
Der underneath for the juice to gather
and which is connected to a set Of suction
pumps for craving the juice from the cane
during the crushing operation into etanks for
holding the pure cane juice. After all me
Juice that can be extracted by powerful
pressure, the exhaust steam is then admitted
into the crushing cylinder between the ram
and the megasse to absorb by vapour any
Juice left in the cells of the cane. When the
pressure is again applied the diluted Jnlce
now in the msgasse il drawn off as before mo
tanks. This diluted juice is found to Dc only
two degrees Baume less in density than the
pure Juice. The piston at bottom of crushing
cylinder is then lifted up by a piston rod
passing through the bottom OF crushing
cylinder to the top Of same, when the megaSSe
is removed from the crushing platform by a
horizontal hydraulic ram having a head fxSd
to it extending the whole width of the mouth
Of the cylinder, which passes the megasse on
to d trolly or endless band to be carried away
to the boi ers to be used as fuel. The whole
of the operations of feeding, crushing, dis
charging, a d pumping is performed by one
man from the platform of the machine. The
second cylinder is the hydraulic cylinder for
crushing, and the third, or top, cylinder is tor
the purpose of dollying the megaSse when 1t
is subjected to the vapour bath, and to give
a rapid up and down motion to the hydraulic
ram. This ram is fitted with aiS-tight rings
to prevent air passing into the suction or va
cuum chamber. The largest machine Will
not occupy more than eight feet of floor space
and is self -contained. 1t is intended to make
five different sizes off machines, capable OF
dealing with 5, 10, Is, 20, 25 tons of cane per
hour. The advantages claimed for this ma
chine over all Others now in use are as 10. W
1t ensures complete extraction OF ali sugar
from the cane. This result is obtained 10y
one machine and at one operation. The risks
of breakdown are reduced to the minimum, as
this m chine he's no gearing or revolving
