PROBLEM TO BE SOLVED: To reduce the discharge capacity that accompanies non-working motions, while avoiding the increase at the time of rush current of the scattering of powdery and granular materials, immediately after the start of a vehicle or the start of a blower motor, by continuing the driving of a blower during non working.SOLUTION: An apparatus for transporting powdery and granular material is provided with a blowing means 3 for sending in a transport air flow to a transport channel of the powdery and granular materials, and an airflow control means 5 for imparting airflow resistance to the powdery and granular material transport channel located on a farther upstream side in the airflow direction, based on the position of supplying the powdery and granular materials to the transport channel, and limiting the airflow to the downstream side in the airflow direction.COPYRIGHT: (C)2008,JPO&INPIT【課題】 非作業中の送風機の駆動を継続して、発進直後の粉粒体散布やブロアモータの起動時の突入電流の高騰を避けながら、非作業中の作動に伴う放電容量を少なくする。【解決手段】 粉粒体の搬送通路に対して搬送用の風を送り込む起風手段3を備え、搬送通路への粉粒体供給箇所よりも送風方向上手側における粉粒体の搬送通路に、通風抵抗を与えて送風方向下手側への送風を制限する風量制限手段5を設けてある。【選択図】 図7
