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

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.
