Abstract
Abstract A sorting device, particularly for trout and fish eggs which is of the type having an inclined wall against which the eggs are launched and caused to rebound a distance apart depending on the resilience thereof. Collecting means are provided for receiving the eggs according to their different trajectories. The device comprises a tank for receiving eggs and water having a rotating drum associated therewith having a plurality of cups on the outer surface thereof. Each cup is adapted to receive one egg therein and the cups are arranged in parallel transverse rows. The bottom of the cups is perforated so as to permit the water to be discharged therefrom. A fan is provided in order to dry the eggs in the cups through the perforated bottom thereof and a pneumatic launching device serves to launch the eggs against the inclined wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A sorting apparatus generally for trout and fish eggs of the type comprising an inclined wall, said wall providing a surface against which eggs are launched and caused to rebound therefrom according to different trajectories depending on the resilience of the eggs and spaced collecting means, for collecting the eggs according to their trajectories; wherein, said apparatus comprises a tank adapted to receive the eggs together with water, and a rotating drum associated to said tank and provided with a plurality of cups on the outer surface thereof, said cups being aligned in parallel rows extending along the drum generatrices and having a perforated bottom, each of said cups being designed to separately accommodate one egg therein so that, upon rotation of said drum, the eggs contained in the cups are removed from the water.
Claim 2
Dependent Claim
135 words
A sorting apparatus generally for trout and fish eggs of the type comprising an inclined wall, said wall providing a surface against which eggs are launched and caused to rebound therefrom according to different trajectories depending on the resilience of the eggs and spaced collecting means, for collecting the eggs according to their trajectories; wherein, said apparatus comprises a tank adapted to receive the eggs together with water, and a rotating drum associated to said tank and provided with a plurality of cups on the outer surface thereof, said cups being aligned in parallel rows extending along the drum generatrices and having a perforated bottom, each of said cups being designed to separately accommodate one egg therein so that, upon rotation of said drum, the eggs contained in the cups are removed from the water.
Claim 3
Dependent Claim
32 words
A sorting apparatus according to claim 1, wherein: means are provided adapted to cause an air flow through said perforated cups in order to dry the eggs in the cups by ventilation.
Claim 4
Dependent Claim
33 words
A sorting apparatus according to claim 1, wherein: said apparatus comprises a pneumatic launching device for launching the dried eggs against said inclined wall by blowing action exerted thereby through the cup holes.
Claim 5
Dependent Claim
32 words
A sorting apparatus according to claim 3, wherein: said inclined wall is located in front of the egg launching line and is perpendicular to the direction of the flow of blown air.
Claim 6
Dependent Claim
29 words
A sorting apparatus according to claim 1, wherein: said collecting means have a slanting bottom to allow water flowing therein to transfer the sorted eggs outside the sorting apparatus.
Claim 7
Dependent Claim
32 words
A sorting device according to claim 1, wherein: a counter is provided for counting the sorted eggs according to the rows of cups in the drum or the revolutions of the drum.
