CREAM ON FARM
IMPROVES THE QUALITY

Agricultural College News-Notes:-
The necessity OF cooling milk i'm
mediately after il Is drawn is pretty
thoroly understood by most dairymen-
Too often. however, the farmer selling
cream, fails TO realize that there
would b. a corresponding improve
ment in his cream II il were cooled
promptly after separating. The most
efficient cooling can be obtained By
the use Of surface cooler, over which
the cream is passed in thin film,
while water is circulated thru the in
| side. Ordinarily the volume of cream
! l. insufficient TO justify the use Of
cooler. In that case il should be
put into ;all cylindrical can of the
shotgun type and set in cooler until
thoroly cooled, after which ii may be
added 10 the other cream. In no case
should warm cream be added TO n
can Of cold cream, If the best quality
is TO be secured. Care should also
be taken in adding each batch of fresh
cream To see that the whole can Is
thoroly stirred. This will insure 4
smooth, even cream and n correspond
| ing improvement in quality
A suitable tank for holding the

be so located as To be easily drained.
This will facilitate cleaning and insure
sweet, sanitary condition, which is

changed frequently. II should be To-
Gated in or near the milk room and
should have a tight cover. The ma
terial to be used in such tanks will
depend on local conditions. Insulated

while from the point of view of
cooling, wooden tanks give good re-
suits, an insulated concrete tank is
much more desirable, rs it is easily
built and can be set partly in the
ground. A wooden or galvanized
iron tank does not last long under
similar conditions. When the tank
is set low, cans of milk can be lifted
in or out with much less effort than
when it is entirely above the ground
The total thickness of the walls of
an insulated concrete tank should be
S inches, divided into two walls, the
outside being inches, then 2 inches
of good insulation and the inside wall
inches thick. The concrete mix

ent, parts clean, sharp sand, and a
parts broken stone or gravel. For
the purpose of interpreting, hydrat-
ed lime equal to 10 per cent by weight
of the cement should be added to the
mixture. The insulation used should
be coated with and set in hot asphalt,
which should be allowed to become
thoroly dry before the inner walls of
the tank are put up. The inside walls
should be very carefully troweled, so
as to insure a smooth surface without
projecting particles"
Where ice is not available, well or
spring water may be used. In such
case the water should be allowed to
flow thru the tank continuously. This
may be done by running a pipe to
the water troughs thru the mill;
house. The inlet to the tank should
be at the bottom, so that the fresh
water will come in and circulate up
and around the cans and run out at
the overflow near the top. Where
the water is piped any great distance
from the well or spring, the pipe
should be laid several feet under the
ground to avoid the surface heat
from the sun.
The best results will be obtained
if the cream can be cooled to so de-
grees or lower, within an hour OF
separating and held at that tempera-
lture until shipped.
