Study Notes
Transportation of Fresh Products
- Fresh products are transported in specialized refrigerated cargo ships known as 'reefer ships'.
- The cargo may be chilled or frozen and is carried in cartons.
Shift to Refrigerated Containers
- Refer ships fleet is shrinking.
- Most shippers prefer to use refrigerated containers.
Modern Refrigeration System
- Air is blown over successive rows of pipes containing a coolant.
- The air is then channeled into the cargo compartment through delivery fans and series of ducts.
- The air circulates throughout the cargo and is then exhausted via the exhaust fan.
- The modern machinery provides: • Humidity control • Temperature control • Air changes control (through fan speed and adjustable mix of fresh air and circulated air)
Test your knowledge on reefers ships and refrigeration systems used to transport chilled or frozen cargo. Learn how air is circulated throughout the cargo compartment to maintain the required temperature.
