Pasteurizer Operators Workshop

The course begins with a focus on the composition and microbiology of milk, to set the stage for the conditions needed for pasteurization and cleaning. The course focuses on the components of the HTST pasteurization system, including instrument control systems, auxiliary equipment such as homogenizers and separators, and flow control technologies. Operation of the system is addressed from start-up through clean-up and sanitation. Vat pasteurization and UHT processing are also discussed. The course wraps up with a lecture on problem-solving techniques and a trouble-shooting exercise.

Hands-on laboratory exercises in the pilot plant include leak detection of pasteurizer plates, and a demonstration of the quarterly regulatory tests conducted by the Pennsylvania Department of Agriculture on the HTST system of the Penn State Berkey Creamery. 

The course emphasizes interactive learning through the integration of classroom discussions and hands-on exercises in the pilot plant and the Berkey Creamery. Breaks and lunches encourage further discussion with the Penn State, regulatory, and industry instructors.
