Perishables have a shorter shelf life than necessary due to the amount of time they spend in the supply chain before reaching a temperature controlled atmosphere. Cooler temperatures increase the time before perishables begin to perish. If perishables were cooled right at harvest their shelf life could be increased dramatically but, that isn’t possible with today’s infrastructure.
Warehouses are required because they provide the docks and levelers that are needed for trucks to load and unload products including perishables but, the time it takes to get perishables from the field to a temperature controlled warehouse is the time that perishables degrade the most. The video above shows a system that allows refrigerated trailers to be loaded directly out of the field because no docks are needed for loading.
