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.
