A method of checking eggs for flaws and blemishes, such as blood, dirt, cracks, a leak or aberrant form, in which the eggs, while located on a conveyor roller track, pass an inspection station, where the unwanted eggs are determined as such, with the information of the respective eggs being stored in a tracking memory (shift register), after which the unwanted eggs are discharged separately, whereby more in particular for a fast detection of flaws and blemishes, the eggs for for a short period be lifted off either of two bearing rollers of the conveyor roller track, and brought into contact with other rollers being driven at high peripheral speed, during which period the egg is sensed by a detector, which transmits the result of the sensing to the memory.

In an apparatus for inspecting eggs for flaws or blemishes having a conveyor roller track for conveying eggs with adjacent conveyor rollers thereof adapted to receive a single egg, a light source disposed adjacent the conveyor roller track, a light detector for generating information as to which eggs have flaws or blemishes and storage means for storing said information in a tracking memory for subsequently discarding flawed or blemished eggs, the improvement comprising an auxiliary roller track having a plurality of auxiliary rollers, means for temporarily interdisposing an auxiliary roller between said adjacent conveyor rollers such that the egg supported thereby is temporarily supported by a first of said conveyor rollers and the interdisposed auxiliary roller and lifted off of the second of the adjacent conveyor rollers, means for causing the interdisposed auxiliary roller to rotate at a greater peripheral speed than that of the first of said conveyor rollers to impart such rotation to the egg so as to increase the speed of inspection thereof by said detector as the said rotating egg passes thereby.
