Introduction
1. Standard Overview
GB/T33433-2016 "Marine Controlled Atmosphere Fresh-keeping System" standard is applicable to the design, manufacture and acceptance of controlled atmosphere fresh-keeping systems for various types of ships. It standardizes the composition and classification, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage of the system.
2. Comparison of standard frameworks
| Standard dimensions | GB/T33433-2016 | SBJ16-2009 | GJ B4000-2000 |
|---|---|---|---|
| Technical requirements | Nitrogen production volume shall not be less than the design value | Airtightness requirements for controlled atmosphere storage | Protection level shall not be less than IP20 |
| Test methods | Nitrogen concentration test | Pressure test method | Vibration test method |
| Inspection rules | Each system is checked item by item | Sampling inspection | Type inspection |
3. Implementation suggestions and application cases
Implementation suggestions:
- During the system design phase, the particularity of the ship environment, such as high temperature, high humidity, vibration and other factors, should be fully considered.
- It is recommended to adopt a modular design to facilitate maintenance and upgrade.
- When purchasing, products that meet the standards and pass the type inspection should be selected.
Application case:
A certain ocean-going cargo ship uses a modified atmosphere preservation system in accordance with the GB/T33433-2016 standard. By precisely controlling the nitrogen concentration, temperature and humidity, it successfully extends the shelf life of green leafy vegetables to 50 days, and the total edible rate reaches more than 85%.
