1. A flowable material conveyor comprising, an air carrier medium source providing a carrier mediummoving at a conveying speed,a flowable material source providing flowable material,a mixing unit connected to said carrier medium source and said flowable material source for mixing the flowable material into said carrier medium and accelerating it to the conveying speed of the carrier medium,said mixing unit having a chamber with a substantially 360°

  • curved inner wall surface with a radial center and with an inlet connected to said carrier medium source positioned to move said carrier medium in a stream along said 360°

    curved inner wall surface and develop a centrifugal force,said chamber having an outlet positioned to provide a discharge for said carrier medium moving along said inner wall surface,a flowable material inlet in said chamber at the substantial radial center of said 360°

    curved inner wall surface whereby a vacuum is generated at said radial center by the centrifugal force of said carrier medium moving along said curved inner wall surface which in turn draws said flowable material into the stream of moving carrier medium,said 360°

    inner wall surface includes an outside circular wall extending to said outlet and an inside substantially circular wall oppositely disposed to said outside circular wall and on the opposite side of said radial center therefrom, said inside substantially circular wall extending between said inlet and outlet with the radius of curvature of the outside wall being greater than that of the inside wall whereby air and flowable material are accelerated moving along said inner wall relative to said outer wall at said outlet for maintaining said vacuum at said radial center.
