Fig. 69. Skim-milk tank and pasteurizer. 



The pasteurizer is placed on top of the skim-milk tank 

 and the pasteurized skim-milk flows through a pipe which 

 runs to within an inch or an inch and a half of the bottom 

 of the tank. A pipe so placed will tend to destroy a por- 

 tion of the foam formed in the heater. The tank is of 

 ample size to hold the foam not thus destroyed, which, 

 during the early summer, is quite considerable. The larger 

 the tank the less trouble will be experienced from the 

 foam.
