Classification of Cold Storage Racking

Cold storage racking refers to the shelving units specifically designed for storing goods in cold storage facilities. These racks are typically based on shuttle racking and push-back racking systems, which are then carefully customized to meet the specific requirements of cold storage environments. Cold storage racking must be able to withstand the low temperatures and high humidity typical of cold storage facilities, which can be harsh conditions for steel products. Therefore, cold storage racking is a specialized type of custom racking system.

The cold storage racking industry has evolved over multiple periods, and today, it has developed into several key types based on the storage temperature and methods. Cold storage racking includes ultra-low temperature storage racking, frozen storage racking, refrigerated storage racking, and controlled atmosphere storage racking.

Ultra-Low Temperature Storage Racking

Ultra-low temperature storage racking is primarily used for storing goods that require temperatures below -20°C, such as certain frozen fish, frozen meats, frozen seafood, frozen ready meals, and ice cream. This system ensures that the goods experience minimal quality degradation under ultra-low temperature conditions, extending their shelf life.

Frozen Storage Racking

Frozen storage racking is mainly used for storing goods that require temperatures between -2°C and -20°C, such as frozen poultry, frozen meats, smoked products, and butter. This system ensures that the goods maintain their best freshness, nutritional value, and food quality within this temperature range.

Refrigerated Storage Racking

Refrigerated storage racking is used for storing goods that need to be kept at temperatures between 2°C and 10°C, such as fresh fish, dairy products, alcoholic beverages, butter, eggs, and ham. This system ensures that the goods maintain the best taste and nutritional value within this temperature range.

Controlled Atmosphere Storage Racking

Controlled atmosphere storage racking uses artificial refrigeration to create a low-temperature environment and adjust the composition of the gas medium. This process helps suppress the physiological activities of fruits and vegetables, thereby extending storage time, maintaining freshness, and prolonging the shelf life of fruits and vegetables for better marketability.

The design and application of cold storage racking not only enhance the utilization of warehouse space but also effectively improve storage efficiency and ensure the quality of goods. With the continuous development of technology, cold storage racking is evolving towards higher efficiency, environmental friendliness, and intelligence, making it an indispensable component in modern cold chain logistics and food safety management.
