空輸送装置。 An opening/closing mechanism that opens and closes a supply valve for supplying the powder and granular material stored in the hopper to the transport pipe, an opening detection mechanism that detects the opening of the supply valve, and a vacuum that detects the vacuum pressure in the transport pipe. The pressure detection mechanism receives signals from the vacuum pressure detection mechanism and the opening detection mechanism, and opens the supply valve corresponding to the detected vacuum pressure according to the preset relationship between the supply valve opening and the vacuum pressure. A vacuum transport device for powder or granular material, characterized in that it is equipped with a control device that operates the opening/closing mechanism so that the opening/closing mechanism is controlled at the desired speed.
