At J.C. Younger (JCY), it is not only about manufacturing and remanufacturing the best chillers in the industry. It is also about staying up on the latest innovations that can improve what we do for our customers. At other times like now, it is just fun to revisit history and those inventions that have brought us to where we are today.

The dairy industry has a history dating back to times that are hard to imagine with the technological advances we have today. Today’s dairy farms deliver this delicious beverage to us all. Wow, is right. Did you catch where chillers come into play?

Discoveries that Helped Revolutionized the Dairy Industry

As most everyone knows, we are one of the most advanced countries around the world. Companies utilize innovative systems that safely produce beverages and food products. One of the industries that chillers helped to revolutionize in the United States is the dairy industry.

The Pasteurization Process

The “Historical Timeline” of milk production, as found on ProCon, takes us way back in time to 8,000 BC. Thanks to Louis Pasteur, his discovery of pasteurization has allowed us to consume milk without harmful microbes that he proved to be found in milk and wine.

The Cooling Process before Chillers

As found on Wikipedia, “Dairy farming” gives us the history of milk preservation. It is the process of cooling milk that has been “the main method by which milk freshness has been extended.” Before electricity and refrigeration, “windmills and well pumps” not only helped to provide cool water for the animals, but they also served to help preserve milk while waiting to be taken to the local markets. “The naturally cold, underground water would be continuously pumped into a cooling tub or vat.” What a foundational idea for our chillers today.

The Cooling Process with Chillers

Milk cooling process evolved once refrigeration was invented. A plate heat exchanger(PHE) is an important device that is used to remove heat from milk being passed through these plates. Along with the process of using underground water to cool milk, chillers have been added: “to remove the remaining heat with a mixture of chilled, pure water and propylene glycol.”

Types of Chillers for the Dairy Industry

J.C. Younger has been working with the Dairy Industry for years, and we know how important it is to our customers and milk consumers alike to manufacture quality and reliable chillers for the milk production process.
