Introduction
Interpretation of the core content of the standard
As the supply and marketing cooperative industry standard (ICS 97.130.20), this specification systematically stipulates the full-process management requirements for fruit cold storage and controlled atmosphere storage, including:
| Management dimensions | Cold storage requirements | Special requirements for controlled atmosphere storage |
|---|---|---|
| Temperature control | Error <0.2℃ | Need to cooperate with gas regulation |
| Humidity management | Error <3% | Same standard |
| Safety protection | Refrigerator alarm | Need to add breathing equipment and hypoxia alarm |
Key technical points
1. Refrigeration system management
- Condensation temperature control: The temperature difference between the inlet and outlet of the water-cooled condenser should be maintained at 5-7℃
- Defrosting specifications: The defrosting water temperature is strictly controlled within the range of 10-25℃
- Winter antifreeze: Pipeline antifreeze measures must be taken
2. Special project for gas conditioning system
Take apple gas conditioning storage as an example:
- Before storage, it is necessary to pass the SBJ 16Standard air tightness test
- Gas adjustment sequence: Oxygen adjustment first → then carbon dioxide adjustment → finally ethylene treatment
- Safety operation requirements: Work in the warehouse must be done by two people with respirators, and the time should not exceed 15 minutes
Implementation suggestions
1. Personnel training system
Establish a three-level training mechanism:
| Basic operation | Health certificate + pre-job training |
| Special operation | Certification required for work (refrigeration/gas conditioning equipment operation) |
| Emergency handling | Quarterly accident drills |
2. Smart upgrade path
Recommended configuration:
- Distributed temperature monitoring system (2-3 measuring points per 100m³)
- Automatic gas composition adjustment device
- Electronic cargo label management system
3. Standard evolution trend
Compared with GB/T 30134-2013 "Cold Storage Management Specification", this specification adds:
- Special management requirements for gas conditioning equipment
- Fruit core temperature monitoring standards
- Specific parameters for gradient cooling (see Table 1)
