1. A particular object conveying device for conveying particles of a predetermined size, comprising:

  • a stagnating portion;

    a disc-shaped rotor having an outer circumference with a plurality of grooves formed equidistantly about said outer circumference, said grooves being of a size and shape to hold only a single one of said particles of predetermined size, said rotor rotating about a rotary shaft within said stagnating portion;

    a discharge path for discharging said particles from said rotor, wherein said stagnating portion has a gap and is disposed on a side of said rotor, said stagnating portion has a cross section defined substantially by two radial lines and an arcuate line to form a partial section of a circle, so that said grooves pass said stagnating portion when ascending, and excess particles taken up in movement of said rotor fall into said stagnating portion;

    a tubular flow passage coupled to said discharge path;

    a spiral stream device that allows a fluid to flow into said flow passage from a tangential direction to create a spiral stream of said fluid;

    a supply pipe, connected to said discharge path, that receives one of said particles suspended in a first atmosphere;

    a first section in which said one of said particles and said first atmosphere contact said spiral stream in proximity to an exit of said supply pipe such that said first atmosphere is separated from said one of said particles; and

    a second section that suspends said one of said particles in a second atmosphere, and discharges said one of said particles and said second atmosphere.
