In order to ensure the consistency in the direction of fresh eggs under package, a device for automatic orientation of the blunt and tip sides of eggs, which is composed of the roller delivery system, veering system and regulator drive system was developed. Based on the principles of mechanical transmission, the design methods for the axial motion and the oriented roll were established, also the construction parameters of the device were determined. The experimental results showed that the axial motion of eggs was stable. The roll over the length was fluent and the attitude was reliable, besides. The accuracy of the orientation was 100%. The egg-orientation speed of the device in single channel was 0.87～1.22 eggs per second. The nominal egg-orientation speed (in two channels) was 7200 eggs per hour.
