CONDITIONS AFFECTING RICHNESS OF CREAM 



reverse was the case. As the speed was reduced the ratio of skim 

 milk to cream and the per cent of fat in cream increased. These 

 differences are due to the relative position of the skim milk and 

 cream outlets. 



Effect of Rate of Inflow on the Richness of the Cream. The 

 rate of inflow exerts a marked influence on the richness of the 

 cream as shown in the table below. 



Table 15. Effect of Rate of Inflow on Richness of Cream. 



Small Inflow 



Normal Inflow 



Large Inflow 



The results in table 15 show that the richness of the cream 

 increases as the rate of inflow decreases and vice versa. This 

 is due to the fact that when the rate of 'inflow increases the 

 capacity of the cream outlet increases proportionately greater 

 than the capacity of the skim milk outlet, while a decrease in 

 the inflow causes a greater decrease in the capacity of the cream 

 outlet than in that of the skim milk outlet. The average re- 

 sults of experiments with a small, normal and large inflow as 

 tabulated above show the following proportion of cream to skim 

 milk, Table 16.
