Variable flow rate dehumidification plant and process for granular materials
First Claim
1. A regeneration process of at least one tower of a dehumidification plant of a granular material, comprisingprearranging a dehumidification plant for a granular material, comprising at least one hopper having at least one loading mouth and one discharge mouth for said granular material, at least one upper feeding mouth in said at least one hopper and at least one lower delivery mouth of a gaseous medium therefrom, humidity absorbent material designed to absorb the humidity conveyed by said gaseous medium;
- at least two towers arranged to contain said absorbent material;
supplying structure designed to feed said gaseous medium to said at least one hopper and said at least two towers;
at least one electronic control unit;
detection structure arranged to detect process variables of said plant and electrically connected with said at least one electronic control unit,said supplying structure including at least one first blower,said plant further including comprising distribution structure designed to distribute gaseous medium coming from at least one of said at least two towers thereby feeding it to at least another tower from among said at least two towers, said distribution structure including a second blower equipped with a rotation speed variation device,detecting the process variables of said plant andadjusting, as a function of the detected process variables, the rotation of said second blower, thereby adjusting the supply flow rate of gaseous medium to said at least one tower.

Abstract
A dehumidification plant for granular material, comprising hopper having loading mouth and discharge mouth for granular material, upper feeding mouth in the hopper and lower delivery mouth of a gaseous medium, humidity absorbent material designed to absorb the humidity conveyed by the gaseous medium; towers arranged to contain the absorbent material; supplying arrangement designed to feed the gaseous medium to the hopper and the towers; electronic control unit; detection structure arranged to detect process variables of the plant and electrically connected with the electronic control unit. The plant further comprises distribution structure designed to distribute gaseous medium from of the towers thereby feeding it to another tower from among the towers, the distribution structure being controllable by the electronic control unit between open position, portion of the gaseous medium contained in the of the towers is fed to the towers, and closed position.
