Modular aeration system

An aeration system for aerating particulate material disposed in a storage bin comprising:

• an aerator forming an elongated hollow body for being placed inside the storage bin such that a longitudinal axis thereof is oriented substantially vertical, the aerator being adapted for enabling an airflow therein along the longitudinal axis and for providing the same to the particulate material, the aerator being made of a plurality of modular sections adapted for being stacked upon each other along the longitudinal axis, each modular section being shaped to form a bottom connecting element and a top connecting element placed at a bottom end and a top end thereof, respectively, wherein the bottom connecting element and the top connecting element are shaped such that the top connecting element interacts with the respective bottom connecting element of an adjacent modular section in a directly interlocking manner when mated thereto for securely connecting the modular section to the adjacent modular section, each modular section having a conduit for enabling the airflow along the longitudinal axis, and at least an opening being disposed in the conduit of at least one modular section for providing the airflow to the particulate material with the at least an opening being covered by a cover extending from the conduit downwardly and outwardly such that a distance from an outer surface of the conduit to the cover increases moving toward a bottom end of the cover;
• and,
• an air supply duct for being connected to the aerator for providing the airflow thereto.
