Patent ID: 8021462

Claim:
A regeneration process of at least one tower of a dehumidification plant of a granular material, comprising prearranging 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 and adjusting, 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.
