the experiments show variation in the
test creamranging from / to 10 per
cent from milk separated Immediately
after milking and milk as cold as will
separate. When milk is so cold that
the bowl cogs, the cream outlet also
clogs, with has the same effect on the
cream as | the cream screw had been
set for ifavier cream. There is no
economy II separating cold milk, neith-
er is there satisfaction in operating the
separator yhen the milk is cold. 1t is
always adisable to buy separator
which viii landle cold milk most ad-
vantageousy because there frequently
occur on he farm emergencies by
which coldmilk must be separated. 1t
is to be noed then that the condition
of the mill has much to do with vary
ing test arl the condition is thing
which the farmer cannot be expected
to note twce day because to do SO
is impractical. but he must expect
variation his cream test from this
source.
1t is ourobservation that the amount
of flush wter used in ordinary practice
has a greiter effect on the variation in
test of ceam than reported in the
bulletin. In the experiment from
which the conclusion was drawn only a
sufficient quantity of water was used to
drive the cream away from the bowl,
which amount would not exceed a
quantity 10 run from the separator
without fish water Of Is per cent. The
following morning was frosty and cold.
The milk separated was equal to the
nights milking rs closely as could be
determined by measuring In ten-gallon
cans. Ths cream taken without flush
water was Is pounds as at night. In
flushing she bowl the farmer this time
used hot water from the tea kettle and
not more han three quarts. The water
increased the weight of cream three
pounds, aid reduced the original test
of cream lightly less than per cent.
So here was variation ranging from
to l5 PEE cent on two separations all
on account of careless use of flush
water. This happens on every farm
every day where separator is used.
And the same variation between milk
ings exist greater than two separator
bowls full In practice, however, the
operator uses whatever quantity ID
most convenient. This can best be IL
lustrated by an experience of the writ
er on a iarm recently. The patron
was complaining of the varying tests
of cream sold the creamery. The writ
err went t, the farm and remained over
night. At the evening separation 150
pounds of four per cent milk was sep
arated. The cream obtained was II
pounds of 40 per cent purity, which
would contain six pounds of fat. The
farmer was operating the separator te
demonstrate to me that he was doing
the work right and that he could not in
any way be blamed for delivering
cream of varying tests. In flushing
the bowl he used two gallonpail of wa
ter. This stood in the kitchen sink ane
was handy and he used it all. one-hal1
going into the cream, and when done
he had % pounds of cream testing
slightly more than 25 per cent OF fa'
and yielding approximately six pounds
of fat originally contained in milk sep.
arated. There was lowering of the
test of cream on each days separation
and on each delivery to the station,
There are conditions not within the
farmers control. but this is within his
control and should be controlled. There
is an advantage in separating and de.
livering heavy cream, and after the
separator has done its work there is nc
use in spelling all by using more flush
water than necessary.
Users OF separators inform US thai
their cream screw has not been chang
ed in years and that their cream shoulC
test now as it did years ago. The fact
that the cream screw has not beer
changed is good reason why the cream
tests should not be the same as when
the separator was new. With use the
cream screw wears of and takes the
cream farther from the center Of the
bowl, and therefore produces q thinner
cream. Thick cream 10 produced BY
drawing the cream from the center Of
the bowl, thin by drawing It from q
point nearer the outside, other condi.
tions being equal. The physical con.
dition Of . separator affects the cresm
density, That ID to say, the longer q
