Title: Ventilation system for food stuffs

Abstract: This invention is concerned with a system for ventilating food stuffs, such as potatoes and the like, that are piled up in a storage area. The system employs an arched sheet that serves as a conduit for a ventilating gaseous medium, e.g., air, and it is anchored at its terminal edges in an improved fashion by a base support element that facilitates the passage of air from the tunnel-like interior of the arched sheet to the exterior thereof and into the food stuffs piled against the sheet.
