PROBLEM TO BE SOLVED: To provide a novel neumatic transportation device capable of reducing a load of a bag filter while performing pneumatic transportation.SOLUTION: A pneumatic transportation device 1 comprises a separation chamber S in which an annular peripheral circuit 80 with the top closed and with the bottom opening toward downward of the separation chamber S is formed. The pneumatic transportation device 1 directs an air flow introduced through an introduction pipe 4 toward downward of the separation chamber S revolving the air flow along the peripheral circuit 80, passes the air flow the bottom end of the separation chamber S, and then directs the air flow toward an outlet tube 5. |
