Breaking down barriers
“This is a highly efficient and environmentally-friendly approach,” Ewig continues. “Nitrogen, which exists in the air around us, is a completely natural element.”
Linde’s cryogenic technology is based on creating an air flow within the machine, thereby breaking down a product’s thermal barrier. “Our CRYOLINE® series, for example, delivers heat transfer rates two to three times those of standard tunnel freezers”, says Ewig.
Another key aspect is that at Linde, everything revolves around food safety and hygiene. “All our machinery is built to focus on cleanliness. Our freezers open up and give full access for any cleaning or maintenance exercises”, Ewig says.
ACCU-CHILL® is another highly efficient cooling technology developed by Linde. Its key advantage is efficiency. Conventional cooling tools such as kettle chillers, traditional heat exchangers or scraped surface heat exchangers demand much energy, space and time. ACCU-CHILL BI®, for example, tackles this challenge by pioneering cryogenic gas cooling with an unprecedented energy efficiency of up to 90%.
Modified Atmosphere Packaging (MAP) is yet another technology to extend the shelf life of foodstuffs without altering their physical or chemical properties or adding any unnatural ingredients. “We have developed a range of application-specific packaging solutions under our MAPAX® brand”, Ewig says. “The vast knowledge and extensive experience we have gained in food science can now be harnessed to extend the shelf life of all food products the natural way.”
