Refrigerated cold storage is used for the short-term or long-term storage of chilled and frozen food products at varying temperatures. It is primarily suitable for storing foods like meat and seafood. The temperature in low-temperature storage is below -20°C, as seafood and cold drinks must be kept below -20°C to prevent spoilage; failing to do so, the seafood's freshness becomes distinctly different. The characteristic of low-temperature storage is that equipment is gradually placed into the cold storage at irregular intervals, and after a period, the temperature inside reaches -20°C. There are no specific requirements for this period, but strict control over the storage temperature is required. A typical low-temperature storage has a temperature range of -18°C to -23°C. However, for cold drinks containing dairy products, the temperature should be set at -20°C to -28°C. But these two different temperatures require different levels of equipment, leading to a significant gap in equipment investment.

Refrigerated cold storage is designed to preserve food with such requirements by maintaining the required temperature for quality storage. Because, when the temperature drops below -15 ℃, the freezing rate of food increases significantly, and microorganisms and enzymes basically cease activity and growth, as well as oxidation. Therefore, food can be stored for a longer period with better refrigeration quality. Moreover, refrigerated food also requires a relatively stable internal temperature, as excessive fluctuations can lead to food spoilage and deterioration.

Refrigerated cold storage is widely used:

Refrigerated cold storage is widely applicable, suitable for hotels, restaurants, catering houses, various food production factories, meat processing plants, dairy product factories, cold drink factories, ice cream factories, blood storage centers, health stations, vegetable processing plants, quick-frozen food factories, noodle processing plants, vegetable and fruit preservation, flower companies, edible mushroom and vegetable production plants, farmers' markets, wholesale companies of cold drinks and meat products, fruits, vegetables, flowers, food, beer, grains, seeds, tea, cold drinks, agriculture, meat, poultry, aquatic products, hotels, inns, dairy products, educational institutions, supermarkets, government agencies, and enterprises and institutions.
