We pioneered impingement freezing in the 1990s for a leading QSR processor in the United States that needed a better way to freeze hamburger patties fast, consistently, and at lower cost than cryogenic gas. That same breakthrough is still one of the best ways to protect quality in thin, high-value products today.
Impingement works by directing thousands of high velocity air jets at the top and bottom surfaces of the product. These jets strip away the insulating boundary layer of air that holds heat around the food. Heat transfer increases dramatically, and freezing happens in a fraction of the time you would expect from conventional air systems.
The result? Speed that matches or exceeds many cryogenic outcomes, with more flexibility, stronger hygiene control, and lower running costs.
