will skim clean when skimming a %
per cent or 80 per cent cream, but if
one must furnish d 40 per cent or 45
per cent cream will this machine skim
cleaner than any other providing other
requirements are equal? The separa-
tor. with care in keeping the tempera-
ture of the milk between 80 to 100 de-
grees f., having the machine on a solid
foundation, the bowl running true and
turning the crank at the required
speed, should not have more than five
hundredths per cent Of butter fat in
the skimmilk when Swimming 80 per
cent cream.
A good separator with reasonable
care and attention should last from ten
to fifteen years. with few or no re-
pairs.
When we say that the parts of the
separator which come in contact with
the milk should be so constructed as
to be easily cleaned we do not refer to
the number of parts to be cleaned but
to the construction of these parts. Can
every piece of the bowl be taken apart
so that we have no cracks or shoulders
to clean? If it is a disk machine. will
all of the disks come apart SO that we
can wash them individually, or, il
there is any other device. can it be
taken apart so that all of the surface
will be exposed and be easily washed?
Some machines may be so constructed
that there are only few parts, and
yet these few be more difficult to wash
and keep clean than a machine with a
great number.
The parts coming in contact with
the milk should be heavily timed, as
this makes washing easier and pre-
vents the parts from rusting. If the
parts start rusting it is very tedious
work to keep the machine clean. How
ever. no separator is so constructed
that it can be kept clean and sanitary
without taking it apart after each sep
aration. In order to get the best re-
suits from your machine wash and
scald all the parts coming in contact
with the milk after each separation.
Most of the standard machines have
vertical and horizontal gears, with
each end Of the pinion in a bearing.
thus reducing the chance of the gears
moving out of place to minimum. and
this kind Of gearing will run for years
without any repair or adjustment if
the machine can be easily oiled The
oil and dirt should be wiped off occa-
sionally and the bearings flushed with
coal oil. The oiling of a separator
should be as automatic as possible.
The splash system that is used on some
of the separatOrs makes the oiling au-
tomato. requiring attention about once
a week. and with an oil cup for the
neck bearing we have the danger of
the hot bearing reduced to a minimum.
Although series of oil cups with the
snap lever proves very satisfactory,
oil must be furnished the neck bearing
either by means Of a cup or a heavy
oil pad, because the bowl travels at a
tremendous speed and needs constant
bath of oil to prevent heating The
lower bearing of the spindle must also
be so arranged as to be oiled constant
~ while the machine is in use. The
other bearings must be provided for in
some way or other and. as previously
stated. as nearly automatic as possible
While the construction of the casing
Or frame of the machine may look like
a secondary problem, it really is very
essential for two reasons: First, does
it protect the operator from getting
caught in the gears and chains? Sec
ond. is 1t SO arranged that you can
get at the gears and bearings easily to
clean them occasionally and take out
the old oil or, in case of overflow. milk ?
