Abstract
Adjustable stepped holes strainer, characterized by a round strainer with perforated walls and closed bottom inside which is another strainer of the same characteristics that adapts to the inner wall of the first and can rotate inside it in such a way that holes of both can coincide and allow the maximum passage from inside to outside, or that, at the manipulator's will, the holes do not coincide or only partially coincide reducing the step from the maximum to zero.
