Murray Hill & New Providence, N.J., U.S., January 26, 2015 – “To stay competitive, food processors must respond to a three-way challenge:  They must increase production, reduce operating costs, and maximize yield – all at the same time. Our exclusive impingement freezing technology addresses this challenge,” says Mark DiMaggio, head of Food & Beverage for Linde LLC

The patented Linde Impingement Freezer can typically produce three to five times the capacity of a conventional cryogenic or ammonia-based tunnel freezer in the same linear space. “That means it can substantially lower the cost of many freezing operations,” says DiMaggio.

The Linde impingement freezer is ideal for a range of products -- from marinated or formed chicken or meat products, to prepared foods such as raw cookie dough and fully topped premium pizzas

For Kayem Foods Inc., the largest meat processor in New England, Linde installed an impingement freezer in less than a week -- and essentially doubled the line’s freezing capacity in the same space. The new freezer runs a variety of fresh sausage products, including al fresco chicken sausage links, burgers and grillers, Kayem Fenway Italian Sausage and Kayem Brats. 


  • Foods are frozen with a high-degree of consistency for increased production capacity at highest yields.
  • Reduces dehydration/weepage losses--more than any other cryogenic or mechanical freezing process.
  • Hygienic design makes the freezer easy to clean, which also saves time.

How it Works
In the patented food freezing process, an initial blast of liquid nitrogen spray crust-freezes the surface of the food product.  Food items are then impinged from above and below with a robust, high-velocity flow of nitrogen vapor as they travel on the belt, maximizing heat transfer. The ultra-cold gas flows across and around the food product, and is recirculated as the food travels through the freezer to maximize the efficient use of nitrogen while helping to preserve yield, freshness, flavor and form.

Linde has been engineering cryogenic food freezing and chilling solutions for decades. The Linde food team performs in-plant assessments and works with food processors to develop optimal solutions. For more information, see Linde (, or call: 800-755-9277.
