CONDITIONS AFFECTING EFFICIENCY OF SEPARATORS 167 



hot water after washing. 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 in a 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 necessary 

 to run the machine without feeding milk, the machine should 

 always be flushed with lukewarm water. This will, in a measure, 

 prevent clogging. Scalding-hot water should never be used for 

 flushing the separator. The cream and skim-milk tubes should 

 be carefully cleaned, with the special wire provided for that pur- 

 pose, 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 to prevent it from rusting. It is easier to oil a sepa- 

 rator bowl than it is to scour the rust off later on.
