Mastering Vacuum Cooling: Lower Costs & Better Product Integrity

Is the struggle to cool large batches of ready-to-eat meals, sauces, or pet food quickly—without sacrificing quality—a constant challenge in your facility? For modern food manufacturers, the answer to this costly and time-consuming bottleneck is critical for scaling.

The solution is not another multi-million dollar cryogenic system. At the recent EATS conference, Blentech’s Pedro Navarro delivered a tech talk on Vacuum Cooling, a technology that solves this problem. In his presentation, Pedro breaks down exactly how vacuum technology achieves rapid, uniform cooling by leveraging the simple principle of lowering atmospheric pressure.

Highlights from the presentation include:

• Vacuum System Configuration: A look at how Blentech utilizes Steam Ejectors, Liquid Ring Pumps, and efficient hybrid “Rotajector” systems (from our partner Croll-Reynolds) to achieve deep vacuum.
• The Economic Case: A stark comparison of utility costs. Pedro shares data showing how hybrid vacuum systems can operate for hundreds of thousands of dollars annually, compared to the millions often spent on cryogenic methods like CO2 or Nitrogen.
• The Blentech Difference: How our proprietary control algorithms prevent common issues—like sucking product out of the kettle and into the vacuum line—ensuring consistent results every batch.

By protecting yield and minimizing cleanup, these controls can translate into six-figure annual cost savings in high-throughput operations.

It’s a valuable watch for anyone looking to improve product integrity, increase safety, and significantly reduce operating costs.
