Cryogenic chilling for food processing

Optimize your food production line with cutting-edge cryogenic chilling solutions, designed to maintain precise product temperatures and enhance food quality while reducing energy consumption and spoilage.

Chills, Freezes, and Injects Cryogen for Temperature Control

The ACCU-CHILL® series from Linde offers a range of cryogenic chilling and injection systems designed for precise temperature control in food processing. These systems employ cryogen injection using liquid nitrogen or carbon dioxide, efficiently controlling the temperature in applications such as bakery, meat, seafood, and beverage production. The ACCU-CHILL® systems are distinguished by their rapid and consistent chilling capabilities, aiding in bacterial growth inhibition during mixing and blending processes. With configurations for batch and continuous operations, these systems integrate seamlessly into production lines, providing automated PLC controls that optimize cryogen usage and enhance productivity. Constructed with stainless steel components, they are durable and easy to maintain, with features like flush-close nozzles to prevent contamination. The application versatility spans across solids, liquids, gases, and powders, meeting industry standards and facilitating a wide range of food manufacturing needs.
