Deep freeze with cryogenics

Expanded ranges of cryogenic refrigeration and freezer systems are being introduced by German company Linde to strengthen its position in the food industry.

In addition to its core interests in freezing and refrigeration, the company has been investigating cover packing under protected atmospheres, applications using dry ice, and transport refrigeration.

Linde is placing emphasis on the rapid availability of its freezer systems so that in addition to its standard offerings of cabinets and tunnel freezers, a range of equipment for special applications can also be offered.

Among the equipment being promoted by the company is the Cryoline SC, a freezer tunnel in which products are transported on a film instead of on a metal conveyor. This allows refrigeration using a plate heat exchanger, making heat exchange particularly efficient. In addition, this system can freeze soft and liquid products without leaving the imprint of a metal conveyor. The Cryoline IM tunnel freezer has been developed for the high-capacity freezing of flat products such as hamburgers, and for the slight freezing of products before they are sliced.

With its LIX-shooter, Linde offers a system to cool foodstuffs -- it uses liquid nitrogen or liquid carbon dioxide for use in mixing, kneading, and cooking equipment. Direct injection can be used on formed products such as meat, poultry, and vegetables, and with soups, pasta, and foodstuffs of puree consistency, such as baby foods.
