Gentle Egg grading

As you are aware no egg is the same, that is why they are graded. Egg grading is mostly used in the egg industry to reduce waste and get the quality consumers to expect. Egg grading is the process of sorting and grading eggs by size, shape, weight, color, and quality. Grading eggs is not mandatory, but inspection for egg safety and wholeness is. Grading is a service provided by the U.S. Department of Agriculture (USDA) and paid for by the egg producer.

In most countries, eggs are sorted based on weight and size. The lower-capacity graders meet all the needs of free-range, cage-free, and bio-eggs producers.

Smooth and clean eggs ready for sale

The ideal egg is clean, oval-shaped and the shell is smooth without cracks. One end of the egg is always bigger than the other.

Grading and packing are the same for each egg. First, the eggs are loaded onto the infeed table this can be done directly from the chicken stables (inline) or offline by a loader. From the infeed table, they roll onto the accumulator onto the rollers that take the eggs through to the next part of the grader. If the egg passes the control, it continues the conveyor belt. If the egg is rejected at a certain point, the egg will leave the grader at the first exit. The detection systems look at and through an egg on all sides to make sure that there is not too much dirt and feathers on the shell, there are no cracks and there are no blood clots inside.

Eventually, all eggs are turned in the same position ‘point down’ into the pack ready for transport.  

Did you know that eggs should always be packed point down? Why is that you wonder? The bigger end of an egg has an air cell between the inner and outer shell membranes. This air cell grows slowly as the egg loses moisture during storage and transport. Keeping the air pocket at the top helps to keep the yolk centered and prevents the air cell from bursting, which reduces the risk of egg spoiling.
