PASTEURIZATION OF CREAM 153 



for the boiler, a large portion of the heat used for pas- 

 teurizing- is recovered. Further, if the proper coolers are 

 used, ordinary well water will cool the cream to the 

 ripening temperature without the use of ice. Some have 

 also found it practical to use the exhaust steam from the 

 engine for pasteurizing cream. 



The care and cleaning of the pasteurizer and cooler 

 will, of course, entail extra labor, but the labor thus in- 

 volved will not materially add to the expense of pasteuriz- 

 ing.
