Chilling needs vary significantly from one application to another. To ensure the best fit for your individual process flow, we have developed a variety of delivery systems and devices that bring the environmental and quality benefits of gaseous, liquid and solid (dry ice) cryogenic chilling agents to stationary and mobile applications.
Our ACCU-CHILL™ in-line chilling system, for instance, injects liquid carbon dioxide (LIC) or nitrogen (LIN) directly into mixing or storage vessels for instant results. We also have FROSTCRUISE™ in-transit refrigeration solutions based on LIN. If you need to transport smaller quantities, our SNOWCOOL™ isothermal trolleys rely on dry ice (or CO2 snow) for flexible temperature control. Dry ice can also optimise chilling at your conveyor or packaging station with our Dri-Pack chilling solutions. And if you need larger quantities of dry ice, our pelletiser systems can produce it on site for you.
To ensure precise temperature control and maximum efficiency when dosing dry ice, we have developed a range of standard CO2 expansion nozzles and snow horns. Regardless of whether you need a manual, portable or permanently integrated solution, all snow horns are designed to the highest industry hygiene standards and can be easily adapted to your individual chilling application.
Linde has an in-line chilling system called ACCU-CHILL™ . It is installed on blenders, mixers, tumblers, or batch vessels for the purpose of reducing the foodstuff temperature.
Linde’s ACCU-CHILL, better referred to as 'Bottom Injection,' reduces the temperature of the solid or liquid food products by injecting liquid carbon dioxide (LIC) or nitrogen (LIN) cryogens into the mixing or storage vessel. The cryogen is controlled by measuring several parameters, such as product viscosity, temperature and time to achieve desired temperature or product viscosity.
For example, meat customers will use ACCU-CHILL 'Bottom Injection' to achieve precise temperature control of products such as ground beef and chicken for the purpose of forming hamburger patties or nuggets.
The Linde Dri-Pack cooling system is the solution for processing industries where instant cooling of perishable products is used directly in the packing boxes.
The Linde Dri-Pack system is designed to automatically pour a predetermined amount of carbon dioxide snow into boxes of meat products or perishable products at low speed. The low application rate prevents overflow and the loss of carbon dioxide snow that often occurs with other designs.
These systems can be automatically or manually controlled on packaging lines with conveyors. The systems can be adapted to boxes of different sizes.
The main advantages are:
Getting the cold chain under control with an eco-friendly, low-noise, low-maintenance in-transit cryogenic refrigeration solution.
We developed our FROSTCRUISE® indirect cryogenic refrigeration system to meet the technical, cost and environmental pressures facing the trucking industry today. FROSTCRUISE is an efficient, economical, cryogenic replacement for mechanical, diesel-powered refrigeration units. Not only do mechanical units have a high carbon footprint due to diesel consumption, they are also relatively noisy, expensive to maintain and reliant on potentially harmful refrigerants.
FROSTCRUISE overcomes these environmental challenges by using liquid nitrogen (LIN) as the refrigerant. The LIN is stored at a temperature of -196°C in an insulated on-board tank. It is piped through a heat exchanger with a large surface area to release its cooling power. This causes the liquid nitrogen to evaporate and high-velocity fans circulate the cold air around the truck’s container.
When you are challenged to manage a complex logistic supply chain with several product temperature specifications, maximise shipping coverage and minimise cost, you need a solution that can provide you the flexibility to achieve these competing needs
If reducing the risk of breaking the cold chain while maximising profits is your priority, then our SNOWCOOL® temperature control systems might be just what you have been looking for. It is a highly flexible and economic solution that uses dry ice snow, an extremely efficient and easy to use coolant.
SNOWCOOL trolleys provide the flexibility to deliver different temperature compartments within the same shipping environment, for example shipping fresh and frozen food products in the same vehicle. No matter if you have to transport fresh or frozen foodstuffs, the fully automated SNOWCOOL system always offers maximum protection through constant temperature control. Linde offers transport cooling via trolleys through the Snowcool application.
Linde carbon dioxide snow horns provide a simple, cost effective method to accurately control temperature conditions in your chilling operations.
Snow horns are easily adaptable to most existing chilling systems. At the heart of Linde’s line of carbon dioxide snow generating equipment are Linde’s high and low velocity snow horns. Linde developed low and high velocity design snow horns to suit most conventional and hundreds of custom applications
The unique 3.75 high velocity Snow Horn with its insulated stainless steel body is designed with an annular sub-cooling chamber and provides unparalleled efficiency in converting liquid carbon dioxide into snow. It is used in many cases to produce snow into closed containers such as a mixer or blender.
The Low Velocity Snow Horn (LVSH) series comes in both a 7 inch diameter and a 3.5 inch diameter model and is made of annodised aluminium or stainless steel. This horn is designed to provide a low velocity output of snow for placement in open containers such as boxes or bins without the spillage that would result from a high velocity horn.
