Weighing Scales

The “heart” of the egg graders and a key reason for the design and manufacture with such care and precision. For special requirements the counter weight can be set to any weight category.

Belt Conveyor

An innovative solution which carries out the delicate operation of moving the eggs from the exit of the scales to the hand packing table.


The engineering and the manufacture allows for easy maintenance besides offering the possibility of feeding the eggs either by hand or by in-line feeding conveyor. The limited dimensions of this egg grader permits it to fit into many situations according to individual needs.


All of our egg graders are fitted as standard with a fluorescent candling system.
