Heat Exchanger • 3-section sanitary design
• Section #1 for pre-heating cold raw milk with separated warm skim milk (i.e., cooling skim milk with cold raw milk)
• Section #2 for further heating raw milk with hot water for efficient separation into skim and cream
• Section #3 for further cooling skim milk for holding at ~ 40°F before processing
