ABSTRACT:
A system for analyzing bulk cotton or other flowable solids comprising moving the cotton through a conduit; halting part of the cotton within the conduit while permitting the remaining part to continue movement through the conduit; moving the halted mass in an arcuate pathway toward an interior surface of the conduit; pressing the halted mass against the interior surface; wherein the pressing means is sufficient to press the mass against the interior surface to form a face of uniform cotton density on that part of the mass which is pressed against the interior surface; analyzing such face for a property selected from the group consisting of color, trash content, moisture content, and combinations thereof; and thereafter releasing the pressure on the halted mass to allow it to resume movement through the conduit.
