Abstract:
A vertical shaft processor comprising in combination,a substantially cylindrical shell having an inner wall, processing means in said shell for treating materials that flow by gravity through said shell and a discharge opening for the discharge of treated materials, said processing means including, first and second sets of treating fluid delivery tubes penetrating said cylindrical shell so as to communicate with the interior of said shell, said delivery tubes in the first set each lying in a vertical plane that is substantially perpendicular to the vertical planes containing each delivery tube of the second set, and the delivery tube of each set including at least one opening through which treating fluids can be delivered to the interior of said cylindrical shell, the delivery tubes in said second set constituting individual tubes projecting into said shell different distances with each tube in the second set delivering treating fluids independently of the other tubes in the second set at various radial distances from the central longitudinal axis of said shell.
