Carbon dioxide (CO2) snow, also known as dry ice, is a very effective and easy to use cooling medium. It is best used with snow horns or specially designed nozzles to cool products in mixers, blenders, containers, cartons, combos, or at cutting-up and packaging locations.
Liquid carbon dioxide converts to solid carbon dioxide snow at –79ºC (–109ºF), when it is allowed to expand to atmospheric pressure. When in close contact with a food product, carbon dioxide snow has a deep seated cooling effect.
Carefully optimised and designed expansion nozzles guarantee efficient snow generation and rapid cooling. A variety of snow horn designs are available, from manual and portable, to permanent integrated units. All units incorporate the latest efficiency concepts while meeting the highest industry hygiene standards.
Our numerous freezers meet the needs of a variety of applications. Modern freezer designs use the latest control programs to increase efficiency while meeting stringent hygiene standards.
Cryogenic freezing of food with liquid nitrogen (LIN) and carbon dioxide (LIC) is a well-established practice that relies on those gases’ extreme cold temperatures (–196°C or –320°F, in the case of liquid nitrogen) as they come into contact with food.
The CRYOLINE® family of food chilling equipment meets these modern requirements. To see what will work best for you, please review the information contained in the specific food product or freezer pages.
Services tailored to the food industry
In order to provide a full service to the food industry, we believe it is important to give our customers and potential customers an opportunity to evaluate our equipment for themselves. We do this at our state of the art test centers by simulating production conditions.
Our test facilities back up our theoretical calculations by providing proof of concept demonstrations, illustrating the vast possibilities of cryogenic freezing and cooling. Linde Test Centers are available in most regions of the world and we would be delighted to arrange a trial for you. Please contact your local centre for more details.
Wherever you find Linde, you’ll also find dedicated application engineers trained to support every aspect of a cryogenic freezing installation, from the gas storage tank to the freezer.
Installation drawings often facilitate liaison with plant engineers to ensure trouble free installation. Our service doesn’t stop with installation, once the equipment is in operation our engineers will check the entire system at regular intervals to ensure that everything is in optimum working order.
