PROBLEM TO BE SOLVED: To provide an automatic processor which continuously performs various processing of a large amount of fish eggs, including unloading of the processed fish eggs.SOLUTION: An odd number of cylindrical units are simply concentrically superimposed around the rotation center axis Ax according to an intended use and an environment of usage so as to obtain a layer-stacked continuous supply-type automatic fish egg processor having an inlet port 2a and an outlet port 2b separately disposed on both sides of an agitator body 2. In contrast, an even number of cylindrical units are simply concentrically superimposed around the rotation center axis Ax so as to obtain a layer-stacked continuous supply-type automatic fish egg processor having the inlet port 2a and the outlet port 2b concentrated on the same side of the agitator body 2.
