Centrifugal Rutter.MaLing.

In a report of the late meeting of the Mas
sachusetts Board of Agriculture at Southboro,
given in the N. E. Farmer, we find the fol-
lowing account of a new process of sepsrat-
ing the cream from the milk and of working
and moulding butter;
In opening the discussion of the subject of
milk-setting, Mr.. Burnett gave a short review
of the systems in common use, including the
old shallow pan method, the deep can, cold
water system and the Ferguson bureau meth
cd, and admitted that in good hands excellent
results may be obtained by either. Were he
to confine his operations to a small dairy, he
thought the latter method of setting milk in
large pans, i'll an atmosphere controlled in its
temperature by the use of ice or heat, would
be his choice. The centrifugal method is not
at present adapted to diaries of less than 200
cows. Two machines are in use in his dairy
at Deerfoot Farm-one that may be run with
continuous stream of milk pouring in, while
the cream and skinned milk are as continu-
Ously being drawn off into separate vessels,
and another that receives its fill at once, and,
after being whirled some fifteen or twenty
minutes, delivers the separated milk and
cream without stopping the machine, and is
ready for a new batch. Diagrams on the
blackboard were made for illustrating the OPP
Grafton. The milk is poured into a metallic
tub which revolves at speed of many hun
dred revolutions minute and subjects the
contents to a pressure of 200 lbs. per square
inch, requiring, of course, the very best ma
terial for construction. A ten-horse. power
engine is used for driving the machine, but q
portion of the power is used in the pork
packing establishment which is connected
with the dairy. The principle involved is as
simple as throwing stones and feathers into
the air, the heaviest bodies being hurled the
farthest and with the greatest force. Skinned
milk, being heavier than cream, is thrown to
the outer portion of the revolving VESSEL
while the lighter cream remains near the cen
tire, each portion at the expiration of fifteen
minutes being quite separated and standing in
two perpendicular walls, both being held down
by cover which projects inward over the
milk and cream some six inches toward the
centre of the tub, or basket, as it is usually
called The skimmng is done by inserting
the end of a tube into the revolving mass
while in motion, the cream being delivered
into one vessel and the milk into another
The best success is attained when the milk is
at temperature of about 80 degrees. The
capacity of the machine is about 500 lbs of
milk per hour, and it is run daily from eight
O'Clock in the morning till two o'clock in the
afternoon, or till all the milk received is dis
posed of. Through the past summer some
'OO COWS nave contributed MIX 10 tnlS eStaD-
lishment
At this stage of the proceedings Mr.. Bond
one of the inventors Of the centrifugal ma
chimes came upon the platform with a toy
machine intended to show how quickly cream
and milk may be separated by this process
Four little glass tubes were suspended in as
many metallic buckets and the machine start
ed, when the tubes almost Immediately flew
of into a horizontal position, being held by
their balls to the centre shaft At the expi-
ration of fifteen minutes of patient work at
the crank, which portion of the time was in
the hands of Gov. Long the milk was found
blue and thin in the bottom of the tubes,
while the layer of cream, marked by dis
tinct line of separation, fioated on top.
The same principle has been applied for
working and moulding butter at Deerfoot
farm with more or less success. Butter taken
from the churn and placed in wire basket is
revolved rapidly and entirely freed from but
termilk Moulds attached to the outside of
the basket are filled with butter ready printed
and weighed for market. This is not, how
ever the usual custom at present, as the ma
chinery has not been perfected; but if il
should be, dairy hand work would seem to be
very nearly at an end.
