A method in a vacuum conveying system, which vacuum conveying system comprises at least one feed point (61, 66), a material conveying pipe (100, 101, 102) which is connected to the feed point (61, 66) and at the other end to a separator element (20) in which the material being conveyed is separated from conveying air, and means (3, 3 ) for providing a pressure difference in the conveying pipe (100, 101, 102) at least for the time of conveying the material.In the method, in the conveying piping (100, 101, 102) is provided an intensified vacuum effect (a vacuum pulse) by an ejector device (4), actuating medium of which ejector device is loaded in a pressure accumulator from which it is conveyed to an ejector nozzle for providing an intense suction in the conveying pipe. The invention also relates to an apparatus.
