A closed looped pneumatic transport unloading system in a cotton gin transports seed cotton from a trailer or module into the cotton gin. The closed looped pneumatic transport unloading system includes a fan, a cotton receiving unit, a separator, and a cyclone connected by conveying conduits to form the closed loop. The fan is positioned after the cyclone in the closed loop thereby reducing the wear on the fan. Cotton is input into the suction stream of the closed loop at the cotton receiving unit, and output from the suction stream at the separator. An air stream output from the fan is conveyed into the blow box. By providing a closed loop pneumatic transport unloading system, exhaust from this portion of the ginning process is eliminated.
