Perforated quill for airing cereals or food products in a heap (1). It includes various original features so that correct penetration can be guaranteed even in very voluminous and very heavy heaps. In particular, a stem post (4) of special shape, equipped with a plate (18) for sliding over the ground, and screw connections (11, 12) for joining the lengths (5, 6) of the quill (3) together, are proposed. <IMAGE>
