THE DAIRY.
ABOUT PORTABLE CREAMERY
CANS.

Correspondence of the Progressive Farmer.
So much confusion of ideas seems to
prevail regarding the shape, size and
number Of cans to be desired in a port
able creamery, that it seems a proper
subject for letter.
The ordinary round can is, as a rule,
eight and one-half inches in diameter,
is twenty inches high and holds about
five gallons. From outside to center
it is, of course, four and one fourth
inches.
The oblong cans in some port
able cr3amerie8 are seven inches wide.
same height as round cans, and hold
each eleven gallons. Distance from
outside OF can to center is but three
and one half inches. Hence it will be
seen that milk can be cooled more
readily in them than in round cans OF
less than one half the capacity.
When ice is used or water of a tenn
perature Of forty five degrees or lower,
1t Is very easy matter to obtain all
the cream between milkings If the cold
deep setting Or Swedish system is cor
rectly practiced.
Therefore it will not be necessary to
provide, in such instances, more than
single forage for milk. By single stor
age Is meant capacity sufficient to store
milk from one milking to the next.
But there are times when the user of
a portable creamery will be glad Of
double storage, hence an even number
of cans, especially in creameries of
small size, are desirable; this because
when all OF one milking will go in half
the number of cans, double storage will
be provided.
To illustrate: If the user has four
five gallon cans, double storage will be
provided when all of one milking does
not exceed ten gallons. Or, if user has
portable creamery with two eleven.
gallon cans, double storage will be pro
vided when one milking or not more
than eleven gallons.
The above is mentioned because so
many seem to be impressed with the
belief that at least four cans are needed
in order that milk may be allowed to
stand twentY-four hours, Or till second
milking.
A careful reading of the above will
show clearly some points that should
not be forgotten.
FIRST. That it is not the number of
gallons Of milk that can holds that
effects it's capacity for cream raising,
but the distance from the outside to
the center of the can. In can that
holds eleven gallons, if Of proper SHAPE
aud proportion, milk can be cooled
much more readily than in one holding
but five gallons, provided the latter is
in such shape as to make the distance
from outside to center of greater than
in one holding eleven gallons.
Second. It will be seen that double
storage is just as readily provided by
two eleven gallon cans as by four five
gallons.
While this is very simple PROPOSE
tion, it is referred to at this time be
cause so many persons fail to under
stand it.
But the strangest idea, and one that
to quite an extent prevails in some sec,
tions, is that three cans are needed in
a portable creamery of small milk
capacity, say for to 7 COWS. Nothing
could be further from the truth. As
shown above an even number of cans
provide double storage when all the
milk of one milking will go in half the
cans. Bat with an odd humber of cans
three for instance-double storage
will not be provided till ali the milk of
one milking will goin one can and then
one can will be idle.
