Bridgewater, N.J., U.S., February 8, 2017 – The ACCU-CHILL® automated box chilling system from Linde LLC can quickly chill meat, poultry, seafood and other perishable foods directly in their packing boxes with carbon dioxide (CO2) snow. The automated system is the ideal upgrade for operations that manually pack boxes with CO2 dry ice pellets, where over- or under-filling creates temperature inconsistencies.

Designed and built to meet USDA requirements, the instant, on-demand system chills with high process repeatability from box to box. As each packing box is conveyed into the enclosed chilling zone, a sensor is activated and a precise amount of CO2 snow is automatically dispensed on or around the product.

Because CO2 snow is generated only on-demand and exactly where needed, the ACCU-CHILL box chilling system is highly efficient and eliminates the time, labor and costs associated with storing and handling CO2 dry ice pellets. The chilling zone is also designed with an exhaust hood to prevent elevated concentrations of CO2 in the workplace.

The new chilling system handles boxes up to about 24 inches wide, and with its small footprint can fit most automated packing lines.

Precision Box Chilling

The Linde food team matches the automated system to the food product and the plant production process. For example, Linde recently helped one leading poultry producer upgrade multiple manual packing lines. The automated system eliminates the challenge of utilizing dry ice pellets and provides consistent box chilling for various fresh poultry products in up to 40 lb. boxes for shipment to fast food restaurants.

Quickly lowering product temperature is a key requirement in pack-off operations, but highly consistent production chilling is more difficult when manually loading CO2 pellets into boxes. Scooping too much or too little can create uneven product temperatures. In addition, handling can pose safety issues including motion injuries or hazardous conditions from the sublimation to CO2 gas.

The Linde food team performs in-plant assessments, conducts trial production runs at the Linde Technology Center, and works with processors to develop optimal process solutions. For more information, visit Linde (, or call 800-755-9277.
