Harvested fruits and vegetables remain biologically active and keep respiring. They consume oxygen and release carbon dioxide and ethylene. Ethylene is the key gas accelerating fruit ripening, softening and decay. Standard refrigerated containers only slow down metabolism by low temperature with limited preservation effect. The risk of spoilage remains high during long ocean voyages.
The 40HC fruits and vegetables CA reefer container applies Controlled Atmosphere (CA) technology based on stable refrigeration. Equipped with high-precision gas sensors and intelligent control system, it precisely adjusts the concentration of oxygen, carbon dioxide and C2H4 inside the container to create a customized low-oxygen preservation environment for different produce. The system monitors gas composition in real time and automatically adjusts parameters to stay within the preset range.
Meanwhile, the unit integrates independent temperature and humidity control modules. The refrigeration system rapidly cools and maintains stable target temperature to avoid chilling injury. The humidity module automatically adjusts internal humidity to prevent dehydration, shriveling or mold growth. A high-strength sealed container structure is the foundation of CA preservation. Superior sealing blocks outside air and moisture ingress, keeps the internal atmosphere stable and ensures continuous reliable operation of the whole CA system.
It comes with an intelligent control system, supporting local touch screen operation and remote monitoring. Real-time data of temperature, humidity and gas concentration can be tracked during shipment, with automatic alarms for abnormal conditions. Custom CA recipes can be configured separately for apples, grapes, durians, avocados, blueberries and other commodities to achieve refined preservation, extend shelf life, reduce ocean transport shrinkage and increase profit for fresh produce traders.
FAQ
Q: How to simply understand the core principle of the 40HC CA reefer container?
A: In short, it creates a "dormant" environment for fruits and vegetables. Reduce oxygen level and control carbon dioxide concentration to inhibit produce respiration and cut ethylene production. Combined with stable temperature and humidity, it slows ripening for long distance preservation.
Q: Do the CA system and refrigeration system work independently?
A: They work cooperatively while parameters can be adjusted separately. The refrigeration unit controls temperature; the CA system manages O₂, CO₂ and C2H4; the humidity system controls moisture. All three sets of parameters can be customized for different cargo.
Q: Why is container sealing critical for CA reefer?
A: CA preservation depends on stable gas ratios. Poor sealing allows outside air to enter and controlled gas to leak out, breaking the CA environment and sharply reducing preservation performance. Our container adopts high strength steel and professional sealing structure for marine voyage.
Q: What produce can be shipped with the 40HC CA reefer container?
A: It is suitable for climacteric fruits such as apples, grapes, kiwifruits, avocados, durians, mangoes, blueberries, as well as some premium leafy vegetables for cross ocean shipment.
Q: Can I remotely check the gas parameters inside the container?
A: Yes. The intelligent system supports remote monitoring. You can view real time readings of temperature, humidity, oxygen and carbon dioxide. The system will trigger automatic alarms once parameters go out of safe range.
