Zonal cleaning system for transport containers

Abstract

A zonal cleaning system for a hopper trailer. The zonal cleaning system includes a controlled air supply that has air tanks with outlet valves operating sequentially and cyclically for a predetermined amount of time. Upper rail assemblies are positioned relatively about and mounted to the upper portion of the sidewalls and each connects to one of the outlet valves. The upper rail assemblies have nozzles directionally oriented and the sidewall rail assemblies each have a fluid delivery line connecting to one of the outlet valves. One or more drop-down segments connects to the fluid delivery line, and each of the drop-down segments has a nozzle manifold with one or more nozzles. Activation of the controlled air supply expels air sequentially and cyclically through each of the upper rail assemblies and each of the sidewall rail assemblies.
