The vibratory conveyors are used in the industry for continuous transportation of loose substances over short distances (2–10 m). The presented conveyor is designed for transportation in aseptic conditions. To obtain high efficiency for granulated mass with different size of grain and different physical properties it is necessary to set the appropriate vibration amplitude independently of vibration frequency. This is not possible with the conveyors currently being used. Therefore it was proposed to apply the novel drive made up of rotary exciter with digital controller. Moreover some methods for dynamic stiffening of the panels were developed and their effectiveness was ascertained. A digitally controlled exciter allowed dynamic panel stiffening by using light closed panels in construction of the conveyor. The control system with encoders for measuring the vibration amplitude of the panel was also established. A study of the conveyor's prototype shows the effectiveness of the drive system. The possibility of digitally setting the vibration amplitude of the light panel to obtain the maximum productivity for particular materials was also shown in results of the research.
