There are many ways to chill foods during production, but as markets and competition grow, so does the need for higher productivity. Cryogenic chilling systems use either liquid nitrogen or carbon dioxide (CO2) to chill foods or ingredients with high efficiency. They offer a valuable alternative to mechanical refrigeration and other chilling methods, such as manually loading bags of ice or dry ice into mixers, manually packing ice into food boxes or grinding frozen blocks of meat in a grinder/mixer.  

As the global leader in cryogenic chilling technologies for the food industry, Linde has been providing innovative solutions for decades and is uniquely qualified to meet changing demands. Linde food industry experts help processors boost quality and repeatability, and improve throughput with a portfolio of hygienically-designed, state-of-the-art chilling systems, including:

Systems that chill with liquid cryogen.
Advanced ACCU-CHILL® bottom-injection chilling systems chill dough, ground meat or ground poultry from the bottom of mixers or blenders for high efficiency. Now with new hygienically designed LIXHSOOTER® injectors that are easy to retrofit.

Customized liquid CO2 systems for bakeries can chill dry ingredients such as flour or sugar as they flow to a mixer or dough blender to achieve tighter temperature control for more repeatable mixing, blending and forming operations.

Rapid Inline Sauce Cooling systems chill sauces, gravies, marinades, fillings and syrups as they flow from the kettle to the next production step to dramatically improve production rates.

Automated systems that chill with CO2 snow.
New ACCU-CHILL® automated box-chilling systems from Linde provide instant, on-demand CO₂ snow-chilling of perishables including boxed meat, poultry and seafood products directly in their packing boxes on automated packing lines.

The ACCU-CHILL® Combo Chiller is an automated combo bin chilling systems that automatically loads and chills poultry in combo bins with layers of CO2 snow.

Linde also offers:
CO2 snow generating equipment for chilling foods in mixers / blenders, totes, etc. including the new ACCU-CHILL® CSG-4 snow generator--  for chilling meats and other foods manually in combo bins or totes…Plus a range of high-velocity snow horns for spot cooling systems or replacement and upgrades.

A safer, eco-friendly alternative to ice chilling and mechanical refrigeration.

Successful food companies can quickly outgrow conventional ice-chilling methods. Manually loading bagged ice into carts, mixers or combo bins is labor intensive. As production grows, it can create bottlenecks -- and heighten plant risks for motion and back injuries, and cross contamination. In addition, traditional mechanical chilling and refrigeration systems rely on ammonia-based refrigerants, which are hazardous chemicals. In contrast, cryogenic solutions chill with inert gases that are naturally occurring in the environment.

Advanced Chilling Solutions with Liquid Nitrogen or CO2

  • Ground Meat or Poultry Mixer Chilling
    Chilling ground meat, poultry or seafood products from the bottom of a mixer or blender with a liquid cryogen is inherently more efficient than any top chilling method. Linde optimizes Advanced ACCU-CHILL® bottom-injection mixer chilling systems for high efficiency and to meet specific processing requirements, including the special demands of ground poultry.

  • Flour and Dry Ingredient Chilling
    Dry ingredient chilling systems from Linde use liquid CO2 to chill flour, spices, sugar or other dry-mix ingredients as they are pneumatically conveyed to the mixer. The ACCU-CHILL® dry ingredient chilling system can chill ingredients within +/-1 °F of the setpoint for more repeatable mixing, which can, in turn, improve dough handling and forming operations.

  • Dough Chilling
    Chilling dough from the bottom of a mixer or blender with a liquid cryogen is inherently more efficient than any top chilling method. Linde optimizes Advanced ACCU-CHILL® bottom-injection mixer chilling systems for high efficiency and to meet specific processing requirements.

  • Chilling with CO2 Snow
    Generating CO2 snow on demand can eliminate dry ice purchases and the associated storage space and handling for dry ice bins, while the efficient use of CO2 lowers operating costs. It also reduces the worker safety issues associated with storing, moving and shoveling dry ice by hand.

  • Automated Chilling of Combo Bins and Boxed Ice-Chilled Foods
  • ACCU-CHILL® Combo Chilling Systems
    For processors of chicken, turkey, pork or red meat, Linde offers the ACCU-CHILL® Combo Chilling system that automatically loads cut parts into the top of a combo bin while layering the cuts with a stream of CO2 snow. The automated process helps achieve more rapid and repeatable production, improving temperature consistency within each combo bin and from bin-to-bin.

  • DRI PACK® Box Chilling System

    Facilities processing poultry, pork, fish fillets and other high-value chilled foods typically packed with dry ice or water ice in boxes can benefit from the automated DRI PACK® box chilling system. Plastic or cardboard boxes (up to about 2 ft. wide) travel along a conveyor to be automatically filled and chilled at the DRI PACK® station with CO2 snow.


CO2 Snow Generators

The new CSG-4 Snow Generator is ideal for high-volume processing of meat, poultry and seafood, and other raw or fresh foods. Combo bins can be simply rolled into the enclosure, filled with CO2 snow, and then sent to a downstream processing area. Snow is rapidly generated and uniformly distributed into the combo bin through four snow horns. 

Safely generating CO2 snow (or pellets) on demand avoids the sublimation losses associated with storing dry ice for long periods. It can also reduce labor and ice storage requirements.

Linde also offers dual-horn snow generators.
Plus specially designed high velocity snow horns that can replace old or worn snow horns for channeling snow into mixers / blenders, e.g., as well as low-velocity snow horns for controlled loading into totes, etc. at lower volumes.
