Abstract
The invention relates to a method for testing and further processing eggs. According to the invention the eggs upon being supplied are first tested automatically for such major damage as open breaks and/or such dirt as blood stains. Further, each egg is scanned with a beam of light directed at the egg shell and the size of the aperture in the shell or any dirt is measured by a multiple transducer, viz. by counting the number of bright and dark pixels, respectively, and thus establishing the size of the damage or dirt, whereafter through comparison with set values it is automatically determined in what category of damage or contamination the egg in question is to be classified. The invention also relates to apparatus for carrying out this method.
