ABSTRACT:
Apparatus for sorting living eggs from a mixture of live eggs and dead eggs during the process of artificial incubation of salmon, trout, and the like, in which fish eggs fed with water onto a rotary disc are moved radially outwardly to form a row of eggs along a guide plate at the outer periphery of the rotary disc by centrifugal force. A photocell sensor projects light on the row of eggs to detect reflected light to differentiate between the dead eggs and the live eggs, and high speed injection of air moves the dead eggs detected by the sensor to a different radial position on the rotary disc for separating them from the live eggs. Subsequently, the live eggs flow from the end of the guide plate through a good egg acceptance port into a good egg hopper and the dead eggs separated by high speed air flow through a bad egg acceptance port into a different hopper.
