SEPARATION OF CREAM. 145 
General Remarks.—In order to keep the separator in good 
running order, it must receive care. The belt should not be 
too tight, nor too loose. If too tight it is likely to bind, heat, 
and set the bearings of the separator. If too loose it is likely 
to slip, and to wear out more quickly. The machine should be 
well oiled. It is better to use a trifle too much oil than not 
enough. If a bearing is once heated, the machine will never 
run as well again. 
The bowl should be handled with great care. Bowls, or 
parts belonging to the bowl, can be kept from rusting by boiling 
them in water, or by steaming them thoroughly after they 
have been cleaned. If scalding-hot water is used before the 
milky portion has been washed off, the albuminoids will be 
scalded on to such a degree that it is difficult to get them off. 
This applies to all dairy and creamery utensils. Hot water 
is said to be best in which to dip tin or iron-ware after washing 
in order to keep them from rusting. If the bowl, pail, or 
whatever utensil it may be, is turned over to drain after being 
dipped in hot water, the heat taken up by the utensil will ina 
short time perfectly dry the apparatus. If the bowl is steamed, 
it should be heated thoroughly to make it dry quickly. 
If the milk supply gets short during the run, and it is neces- 
sary to run the machine without feeding milk, then the machine 
should always be flushed with luke-warm water. This will, in 
a measure, prevent clogging. Scalding-hot water should never 
be used for flushing the separator. The cream and skimmed- 
milk tubes should be carefully cleaned, with the special wire 
provided for that purpose, each time the machine is washed. 
The contrivances on the inside of the bowl should also be 
handled with care so as not to injure them in any way. They 
should be treated with hot water, as mentioned above, in order 
to keep them from rusting. 
When the bowl is not to be used for some time, it should 
be oiled well so as to prevent it from rusting. It is easier to 
oil a separator bowl than it is to scour the rust off later on.
