A reefer ship is a refrigerated cargo ship, typically used to transport perishable commodities which require temperature-controlled transportation, such as fruit, meat, fish, vegetables, dairy products, and other foods.
TYPES OF CARGOES
Refrigerated cargoes -can be divided into three class
frozen class – example meat, butter, poultry, and fish these cargos are carried in hard frozen state as the temperature around – 8 degree to – 12degree centigrade to prevent the growth of bacteria.
Chilled cargo– example cheese, fresh vegetables, eggs .
temperature maintained in the compartment for these cargos are around -2 degree Celsius to 6 degree Celsius.
maintaining the right temperature is more critical with chilled cargo then frozen cargoes as condensation of moisture due to variation of temperature encourages bacterial growth.
Air cooled cargo – Example fruits , here temperature of around 2 degree to 12 degree Celsius is maintained by air circulation.
The temperature at which the individual cargoes are carried may vary beyond the above-mentioned limit depending on many factors, some of the factors and mentioned below
1)The ambient temperature at the loading port
2)The duration of the voyage
3) The state in which the cargo is delivered like frozen, ready for consumption or any other form whatever is adequate for the situation.
