A grain storage bin includes a cylindrical wall formed by a plurality of panels arranged in rows with a bottom edge of a first row bolted to a top edge of a second lower row. At each joint the bottom edge of the first upper row is overlapped with and outside of the outer surface of top edge of the second lower row and the bottom edge is fastened to the top edge by bolts carrying spacers as to define a first channel along the joint for passage of air. A central air injection duct is formed of a series of generally frustoconical duct pieces arranged in a row suspended on a cable from the roof with a tube portion into which the air is injected fixed on legs at a hopper bottom standing upwardly therefrom. The cable is connected by a spring at the bottom to maintain tension

The at least one cooling chamber is connected downstream of the at least one rinsing chamber and is fluid-connected to the rinsing air feed via an exhaust air line in such a manner that the exhaust air heated in the at least one cooling chamber by the plastic recycling material can be fed into the rinsing air feed of the at least one rinsing chamber. Use of such recovery system and method for recovering plastic recycling material.

The present invention proposes a drying tower with grain flow in parallel and sinuous in combination with reverse and radial crossed air flows in form of Z oblique for the implementation in the drying of grains, seeds, fodder, and fruit. Therefore, the grains are firstly submitted to a first stage of parallel grains flow and reverse crossed air flow in order to standardize the different degrees of humidity of the grains and of their impurities. In a second moment, these grains are submitted to a sinuous grains flow and radial air flow in the form of oblique Z. Such implementation in drying processes of grains upgrades substantially the drying time and the energy spent for such process, generating in this way profit for the food industries.
