The chute is used for products such as cereals that are stored in a silo with the silo then being emptied by the fluidisation of the product using air. It is formed from at least two elements (2,3) arranged in the same direction and aligned one with the other so that one element partially covers the other.The covered area of one element is in contact against the other element over all of its upper part, and not in contact in the area of its lower wings. In this way a tunnel (5) is formed through which a proportion of air circulating in the interior of chute may escape.
