PARTICLE TRANSPORT DEVICE

PROBLEM TO BE SOLVED: To provide a particle transport device capable of uniformly adding a chemical agent to the surfaces of particles while transporting the particles while simplfying the device and shortening the manufacturing time. SOLUTION: The particle transport device 1 transports sodium percarbonate particles on a transport passage 31 in a fluidizing manner by vibration. The transport passage 31 contains a weir-like baffle 41 and side baffles 42a-42c. Between the weir-like baffle 41 and the side baffle 42a, a spray nozzle 15 is disposed. The particles in the transport passage 31 are equalized and uniformed in thickness by the weir-like baffle 41 and sprayed with a surfactant by the spray nozzle 15. The particles added with the surfactant flow in the transport passage 31 while meandering according to the side baffles 42a-42c. The sodium percarbonate particles flow inside the transport passage 31 while being mixed, so that the surfactant adheres uniformly to the surfaces of the particles. COPYRIGHT: (C)2010,JPO&INPIT
