Abstract: A silo for storage and homogenization of powder-like commodities includes a housing with a peripheral wall defining an interior chamber in which a cone facilitating the flowing movement of the commodity is located. The cone has an apex formed with a ventilation opening which is surrounded by an aerating device to which air is supplied. A bottom wall arranged within the housing has an outlet for discharging the commodity from the silo and is provided with pneumatic chutes sloped towards the outlet. A number of sector-like ventilation elements are mounted on the bottom wall which are adapted to admit air to the silo which air rises through the interior of the cone, passes through the ventilation opening and enters the commodity located above the cone.
