Kayem Foods, Inc. (Chelsea, Mass.) is the largest meat processor in New England. More than 100 years ago, founder Kazimierz Monkiewicz (K.M. = “Kayem”) built a reputation for high-quality meats and delivered hand-made sausage products via horse-drawn carriage. Today, Kayem produces over 100 varieties of hot dogs and 300 varieties of deli meats, sausage, and dinner hams to stringent quality standards, shipping nationally. 

A few of its well-known brands include Kayem, al fresco, Jordan’s, Duetchmacher, Triple M, and Genoa. Kayem is the official brand of franks and sausages for the New England Patriots, the Boston Red Sox (including an exclusive license for Fenway Franks® and Fenway Sausage®), as well as several other major and minor league sports venues in the East.

Al Fresco Sausage Processing with Messer

The company’s al fresco chicken sausage, which now includes both burgers and links, has rocketed in popularity in recent years and is now the #1 brand in the U.S. Maintaining high product quality is a priority as demand grows – and that means paying close attention to freezing processes.

The Benefits of Switching to Messer's Impingement Freezer

In early 2011, Messer installed a cryogenic tunnel freezer at Kayem’s fresh sausage plant in Woburn, Mass., but expanding distribution quickly pushed the freezer to capacity. Kayem’s Matt O’Malley, vice-president of manufacturing at the plant, explains: “Al fresco chicken links had really taken off faster than expected, and the successful launch of al fresco chicken burgers required even more line time on that tunnel.”

Kayem reviewed its options in 2012 and decided to upgrade to a Messer impingement freezer, which provides the highest freezing capacity per sq. ft. in the industry, combined with the lowest operating cost of cryogenic freezers.

In early 2013, Messer installed the new freezer in less than a week and essentially doubled the line’s freezing capacity in about the same space.

With the new freezer, the surface of the sausage is instantly crust-frozen with a liquid nitrogen spray and high-velocity nitrogen gas, trapping moisture inside the product. As the sausage continues along the belt, it continues to be impinged from all sides with high-velocity nitrogen gas. This impingement freezing technology by Messer maximizes both production throughput and process efficiency.

How the Messer Impingement Freezer Works

After exiting the Messer impingement freezer, the product is trayed, overwrapped, metal detected, labeled, and put into a master case for final freezing – all in about 90 seconds.

On the input side, a patty machine feeds the impingement freezer via a shuttle conveyor at a 90-degree angle, so burgers are able to drop right onto the freezer belt.

”Links are different," O’Malley says. “We have a very efficient in-feed system where sausage links are fed off a high-speed cutting link system, and then an oscillating belt delivers them to the impingement freezer less than 3 ft. away.”

The plant also runs some Kayem Fenway-branded pork sausage and bratwurst through the freezer as the need arises.  More importantly, Kayem now has room to grow.

Impingement Freezers Help You Save on Nitrogen Consumption

O’Malley reports that high-efficiency impingement technology also reduced nitrogen consumption, “though the capability to more than double our throughput was the deciding vote.”

O’Malley previewed the impingement freezer at the Messer Food Lab, and the installation went smoothly due to advance planning. “We simply gave Messer a target as far as what temperature we wanted the finished product to be and we relied on their expertise to account for equilibration and to avoid freezing product solid on the belt.”

O’Malley also likes the hygienic design. “The entire top of the unit lifts up, allowing our sanitation team full access to clean from top to bottom. It also affords our maintenance team the ability to do a full inspection prior to production the next morning.”
