How are high-temperature cold storage, medium-temperature cold storage, and low-temperature cold storage classified? When considering storage options, standard cold storage solutions are also integral to understanding facilities. What are the classification criteria? What is the basis for this classification? How do I determine which type of cold storage to choose for construction?

First, they can be categorized by temperature:
According to temperature, Cold storage facilities categorize into the following four main types. This helps users make optimal choices based on their products and storage needs:
1. High-Temperature Cold Storage
Typically, high-temperature cold storage maintains temperatures between -5°C and +5°C, making it ideal for preserving fruits and vegetables, helping to extend freshness and reduce spoilage.
2. Medium-Temperature Cold Storage
Medium-temperature cold storage operates between -5°C and -10°C. This range is suitable for storing frozen foods such as ice cream and frozen desserts. It ensures product consistency and flavor retention.
3. Freezing Cold Storage
Freezing cold storage runs at temperatures below -25°C. It is designed for rapid freezing of fresh products like meat and seafood. This helps in preserving their quality before transferring to standard cold storage.
4. Low-Temperature Cold Storage
Low-temperature cold storage holds temperatures between -10°C and -20°C. It is commonly used for long-term storage of frozen seafood and meat. Following standard cold storage practices ensures product safety and quality.
Summary: Selecting the right cold storage temperature is essential. It should be based on the specific type of goods and intended storage duration. This helps achieve optimal preservation and energy efficiency.
According to physical dimensions, cold storage facilities categorize:
1) Large cold storage: Storage capacity of 1,000 tons and a storage volume of 1,000 cubic meters or more.
2) Medium cold storage: Storage capacity of 500 to 1,000 tons and a storage volume of 500 to 1,000 cubic meters.
3) Small cold storage: Storage capacity of 500 tons and a storage volume of less than 500 cubic meters. Standard cold storage solutions are crucial for maintaining optimal conditions in these varied sizes. Therefore, choosing the right size for a cold storage facility depends on the user's productivity and desired turnover rate.
These various types are part of the essential standard cold storage networks that ensure the preservation of diverse products effectively.
