CREAM SEPARATOR TESTS

The agents of the Sharples tubular
cream separators are publishing pretty
extensively over the country test OF
cream separators at the Minnesota
Dairymen's convention at Fairmont.
Mimi But they are quite careful not
to mention the details which show that
Sharples did not comply with rules
laid down in the book of directions for
running the Sharples machine. When
the dairy public examine these they
will see that the Sharples, as we'll as
all Of the others were badly beaten
One of the conditions of the agree
ment was as follows: NO machine
to skim cream of density of less than
80 per cent butter fat" Sharples sep
arator skinned cream Of only rs per
cent butter fat. To have complied
with the conditions it must skim one
fifth thicker or 20 per cent thicker
cream than it did skim, and therefore
Sharples was beaten on this point.
The United States separator
SKINNED cream that tested so per cent
butter fat, just twice as rich in butter
fat as the Sharples. The Sharples
agent, knowing that his separator
perature Of 62 to 70 degrees, would
not and did not comply with the
agreement. All creamery men require
thick cream because it Is so much less
| bulk and so much less weight and
| transportation costs correspondingly
of experience knows, to separate thin
| cream than it is to separate thick
cream and separators that can run
| thin cream cannot run thick cream
under same conditions.
The Sharples book Of directions
/ reads: Turn the crank forty to forty
! five turns per minutes" The average
] of r, io iS -fx1Yo 70 f11sr
per minute. The Sharples was turned
in the test at fiftytwo turns, which is
about rs per cent faster than their
| average direction to the farmers who
buy them The sharples separator
bowl was run at between 10000 and
more than twice as fast as the United
States or any other machine in the
test.
The United States book of direc-
tons reads forty-f1ve to sixty revolu-
lions Of crank per minute, average OF
this is fifty-two and one-half revolu-
tions. In the test the United States
was turned only fifty revolutions, two
and One-half turns less than the aver
age, which is 5 per cent under the av-
erage. Bear in mind then that the
Sharples was operated rs per cent
faster than the average and the
United States ran per cent slower
than average.
All experienced persons know that
the Sharples cannot run at that great
speed of nearly 10000 revolutions of
j the bowl per minute many times with
out giving out and the Sharples COM
pany know it best of any one and
therefore, instruct the farmers to run
! their separator Is per cent slower
i than it was run in this contest and the
sharples people know it gives out
1 quickly enough at that slower speed.
| ReCapitu1at1On:
i The Sharples machine was run
1 nearly 10000 revolutions per minute
or 25 per cent faster than the maxi
mum speed in Sharples instruction
| books and more than twice as fast
as the United States was run.
4 Sharples separator produced very
poor cream testing only Is per cent
i butter fat. The United States sepa-
rator produced very rich cream test
ing 80 per cent butter fat
4 Sharples cream was twice as much
in bulk and weight and only half as
i rich in butter fat as the United States
i cream and therefore would cost twice
! as much to transport it to the cream
i cry.
Sharples machine skinned rs per
cent thinner cream than the rules OF
agreement called for, and SO per cent
i thinner cream than the United States
skinned and SO per cent thinner than
the average creamery man requires
Il to be furnished by his patrons to man
ufacture first quality butter.
4 The Sharples failed in the main
4 points necessary for a good operating
separator.
i The United States excelled in those
4 points looked for by the farmer when
Il purchasing frst-class separator.
