Egg Grading Machine
This machine sorts shell eggs by weight into fixed grades.

Egg Grading Machines
Also called egg sorting or egg weighing machines.
Grading machines sort shell eggs by weight. Most buyers think of this as a packing requirement — retail cartons are sold by size — but it matters just as much on a breaking line.
Overview
What decides the result
A breaking machine is adjusted for a size range. Feed it a wide mix of small and large eggs and yield falls while shell fragments rise. Grading first is one of the cheapest ways to protect both, and it is frequently left out of a first equipment list.

How to choose
- Throughput
Row count sets capacity: 4,000 to 11,000 eggs per hour across the range. Match it to your washing line so neither becomes a bottleneck.
- Number of grades
Five grades covers most breaking operations and straightforward retail packing. Seven grades suits markets with finer size classes where the price step between adjacent sizes justifies the resolution.
- What the machine feeds
Grading for packing and grading for breaking are the same operation with different priorities. Tell us which, because it changes what we recommend.
Not sure which model fits your throughput?
Send your daily volume and your site conditions. We will recommend a model and explain the reasoning — including a smaller machine than you asked for, if that is what makes sense.

Information we need to quote
- How many eggs per hour, and how many hours per day?
- How many weight grades do you need to separate into?
- Does the machine feed packing, or a breaking machine?
- Do you already have washing and candling upstream?
- Local voltage and frequency?
Questions buyers ask
Do I need grading if the eggs go straight to breaking?
Not compulsory, but it usually pays for itself. A breaking machine is adjusted for a size range, and a wide mix of sizes lowers yield and increases shell fragments in the liquid. If your supply comes from several farms or varies seasonally, grading first protects breaking performance.
Does a grading machine detect cracked eggs?
No. Grading sorts by weight. Cracks and internal defects are found by candling, which sits upstream — our washing lines include a candling position.
