<p>The present invention regards a method and a plant for the dehumidification of materials in granular form, particularly of plastic materials. The method comprises the following operating steps: a) providing a number of dry air generators and hoppers containing granular material; b) for each dry air generator evaluating the dry air flow generable and/or high energy efficiency functioning time; c) calculation of the dry air flow rate for each single hopper depending on the characteristics of the granular material; d) activation of a number of generators sufficient to deliver a total dry air flow rate equal to the sum of the flow rates required by the hoppers, the number of said generators and the generators to be activated being chosen depending on the flow rate deliverable by each and/or by their respective ranges of functioning at high energy efficiency according to an energy saving logic; and e) deactivation of the remaining generators.</p> |
