Scale of Points for Judging Cream Separators 



292. If a number of cream separators are to be tested they 

 may be compared with each other according to the following 

 standard of points : 



Skimming efficiency 60 



Construction 10 



Ease of cleaning 20 



Power required 10 



100 



Recording a Separator Test 



293. The capacity and the skimming efficiency of a separator 

 may be recorded with the following observations : 



1. Date 



2. Name of separator 



3. No. of separator bowl 



4. Speed of bowl, r. p. m 



5. Temperature of milk 



6. Weight collected in minutes. 



7. Cream Ibs. Skim milk Ibs. 



8. Skimming per hour .Ibs. 



9. Proportion of cream from milk 



10. Test of skim milk 



1 1 . Test of cream* 



12. Test of the whole milk 



294. A series of records like the above may be made when 

 the separator is running below speed as well as at normal speed. 

 This will show the effect of variations in speed on the skimming. 



Other tests made when milk is skimmed at different tempera- 

 tures and when more or less than the advertised amount of milk 



This may be calculated if necessary.
