Industrial dairy chillers are essential for efficient milk processing as well as lowering your processing costs. Their primary roles are to remove heat during the pasteurization process and maintain milk at a cold precise temperature required to preserve quality, ensure food safety, and increase shelf life. If you’re considering an industrial-grade dairy chiller for your farm operation, you may be interested in understanding how a chiller operates before investing your hard-earned cash.

In this post, we’ll break down everything you need to know about how a glycol-water industrial dairy chiller works to enhance production – and profits to your bottom line.

How industrial dairy chillers work

Most industrial dairy chillers are called plate chillers or milk plate chillers because they use a stainless steel plate heat exchanger to draw heat from the pasteurization process, which is more hygienic, involves less labor, and is more cost-effective.

The following is a step-by-step summary of how these heavy-duty plate systems work:

Step 1: Milk is pumped through stainless steel pipes into large refrigerated vats.

Step 2: The dairy chiller funnels the milk from the tanks through stainless steel plates.

Step 3: Milk flows to the opposite side of the dairy chiller, where there’s a coolant mixture of glycol and water.

Step 4: The mixture cools the milk to the precise temperature you need.

Choosing a dairy chiller

Dairy chillers are available in air- and water-cooled options. Here’s how to tell which one might be best for you:

Air-cooled dairy chillers

Air-cooled dairy chillers rely on ambient air to remove heat from your dairy pasteurization processes. Choose these systems to:

  • Reduce energy usage
  • Conserve space
  • Save money when part of a quick installation package

Water-cooled dairy chillers

Water-cooled chillers use water from your well or city water system to remove heat from your dairy pasteurization processes. Choose these systems for:

  • Longer lifespan
  • Quieter operation
  • Energy efficiency
