A container manufacturer should have specific control settings and loading procedures in order to assure that cargo will survive shipping with full protection of the goods to avoid spoilage. Without the proper techniques followed, and depending on the environment, significant loss percentages of cargo will result.
Reefer should meet intermodal transport regulations with regards to size and accommodations for transport by ship, rail and truck and type of refrigeration method. Here’s a list of settings requirements and loading procedures to help assure transport is going to be achieved without incident:
1. Set the refer container temperature for your optimum conditions from the cargo. Most reefer cargo (over 50 percent) consists of fruits and vegetables, and the other 40 percent includes meats and fish. Every type has specific setting and loading requirements. Settings would typically be set because of fresh cargo needing to be chilled, or frozen.
2. Set the ventilation level, that is, the airflow rate through the reefer, rated in CBM (cubic meters) per hour. Air-flow is always from the base of the reefer to the peak. Ventilation for chilled (not frozen) produce must flow around and thru packaging. Ventilation for frozen cargo needs to be closed, which is, just across the cargo.
3. Set the humidity control for optimum conditions according to cargo.
4. Load the cargo. Cargo type will dictate load methods and restrictions. Cargo should be secured in order that, once loaded, it does not move during shipment. Loaded cargo must not violate the maximum red-load line, which establishes the maximum height of cargo within the reefer container supplier, to permit proper airflow return to the refrigeration unit.
5. Airflow should not be restricted looking at the proper flow around and thru the cargo. This will depend on the kind of cargo and be it chilled or frozen. However, if you can find significant gaps round the cargo, or excessively large chimneys in between the cargo, airflow will seek these paths of least resistance and reduce proper airflow where it is required to maintain proper cargo temperature and humidity.
6. Close and seal the reefer. Prepare appropriate shipping and regulatory documents. If marine anchor price has become properly loaded and sealed with temperature, humidity and airflow at appropriate set-points, the container should qcovcf secure without must open it up anytime from the transport process unless regulatory control requires in-shipment inspection.
A suitably loaded and shipped reefer should provide adequate protection and upkeep of goods from start to finish of the shipping cycle. Refrigerated shipping containers tend to be called reefers. A reefer is defined as “a refrigerator (especially one big enough to be walked into), a refrigerator car, ship or truck.” Reefers play a vital role in global trade. They enable companies to ship items like fruits, vegetables, dairy products as well as other items requiring refrigeration when in transit. Reefers ensure goods are shipped on the optimal temperature, humidity and ventilation levels needed for the item these are transporting. Reefer containers are usually fitted with individual refrigeration units that hook in directly using the cargo or reefer ships’ electrical supply.
Refrigerated container vessels are specially created to enable the transport of individual refrigerated container units and they are generally usually present in special areas of the ships cargo hold. Some modern ships contain water cooling systems and some reefers are fitted with redundant cooling systems to make sure perishable cargo is not really spoiled as a result of refrigeration unit going bad.
