30 FIRST LESSONS IN DAIRYING 



put in motion. This prevents the cream stick- 

 ing to the sides of the bowl. 



8. When at full speed, open the milk supply to its 



full capacity and see that the motion of the 

 machine does not cause this to become partly 

 closed. 



9. Put an even pressure on the crank handle at all 



points in its course. Avoid heavy push or 

 pull with no power applied when the crank is 

 at the bottom or top of its circle. 



10. Keep sufficient milk in the supply can to give 



the machine its full feed at all times. 



11. If speed slackens materially while adding milk to 



the supply can, the valve should be closed. 

 If the cream thickens so as to clog or partly 

 clog the outlets, the bowl should be flushed 

 with warm water. 



12. When done separating, immediately flush the 



bowl with enough warm water to remove all 

 cream. Skim milk may be used, though not 

 quite so satisfactory. 



13. Allow the machine to stop of its own accord. 



Do not apply a brake of any kind unless it is 

 provided by the manufacturer. 



14. Wash the machine after each time it is used ; 



rinse first with cold or lukewarm water; 

 cleanse thoroughly with a brush and warm 

 water in which an alkaline washing powder 

 has been dissolved ; rinse and scald with boil- 

 ing water; do not wipe, but shake and allow 

 to dry of its own heat.
