Metabolic processes within particulate durable foodstuffs (for example, grains) which have been stored in storage bunkers produce moisture. To prevent, arrest and/or reduce the accumulation of such moisture, vents are provided at the top and at the side of a storage bunker. Each vent is a pipe. The top-venting pipe is mounted substantially vertically and is provided with a rain shield. The side-venting pipe is closed with a cap which has a perforated or mesh-covered region to permit the ingress of air. The venting arrangement interrupts the normal convection cycle in the stored foodstuff mass and removes moisture-carrying air from the bunker.
