ABSTRACT:
Methods and apparatus are provided for removing clear avian eggs from a moving egg flat without contacting the removed eggs and without contaminating the eggs remaining within the egg flat. Clear eggs are identified by passing an egg flat between respective pairs of light sources and light detectors and detecting the amount of light that passes through each egg. Clear eggs are then ejected from the moving egg flat into a stationary receptacle located above the moving egg flat by applying a first stream of air to the lower end of the clear egg. A second stream of air may also be applied to the egg after the egg has been lifted from the egg flat by the first stream of air. This second stream of air is applied to the egg along a direction substantially transverse to the first stream of air. A third stream of air may be utilized to dislodge an egg from a stuck condition prior to being ejected from the egg flat.
