Pre-Cooling the ContainerPrecooling is pointless if proper loading bay is not provided (and can be worst due to condensation on the interior walls during loading) Note that fresh product box has air holes while frozen product box does not have holes Loading ProcedurePTI test the reefer container to be loaded and Pre-coolSwitch off the unit before opening the doorLoad the product at the correct temperatureClose doorsEnsure correct setpointStartup unit Inspecting container Pre-Cooling the ContainerPrecooling is pointless if proper loading bay is not provided (and can be worst due to condensation on the interior walls during loading Pallet LoadingProperly loaded pallets should allow air flow around and in between the boxes.Allow 100mm gap from rear door Improper loadingExcessive space between the loadLoad placed in the rear of the containerLoad placed in the front of the container Climacteric & Non-climacteric fruitsClimacteric fruits still ‘breath’ after harvest Durian TransportationTo extend shelf life of Durian, it is best to chill Durian right after harvest.
