Claim Text:
1. A vortex pneumatic conveyance apparatus, comprising: an inlet tube, the proximal end of the inlet tube defining a particle inlet configured to receive particles to be conveyed; an air inlet located along the inlet tube, the air inlet configured to receive air from an air source; a vortex member located at the distal end of the inlet tube, the vortex member comprising at least two spiral members located on the outside wall of the vortex member; and an outlet tube at least partially extending from the distal end of the vortex member, the proximal end of the outlet tube defining a particle outlet configured to output the particles to be conveyed, wherein the vortex member is configured to direct the air along the at least two spiral members so that the air rotates along the inner wall of the outlet tube, wherein the length of the outlet tube extending from the distal end of the vortex member is at least 40% of the length of the pitch of the air rotating along the inner wall of the outlet tube, and wherein said outlet tube is made of a stiff material, the diameter of said inner wall of the outlet tube is uniform and the inner wall extending from said vortex member without a bend, curve or obstruction therealong.
