Centerline vs. Wall Loading
A trailer can be either centerline loaded, or wall loaded. Centerline loading prevents heat conduction between the trailer wall and the product as it creates a gap between the wall and the product where air can flow to remove heat that penetrates the wall.
Below, an example of a trailer that has been centerline loaded and the recorder reading this produces:
A trailer that is wall loaded will permit heat to be conducted through the walls and into the product.
Below is an example of a wall loaded trailer and the recorder reading this produces:
Produce loads should not be wall loaded, as this will affect pulp temperatures and recorder readings. To ensure success in deliveries, all produce loads should be centerline loaded.
