Automated oyster grading

Automation is nothing new in modern business. In farming enterprises, the inclusion of automation practices has significantly impacted the viability of many farms by reducing overhead expenses. Automating oyster grading processes has become a necessity rather than a luxury for commercial and water-to-plate oyster growers in Australia and internationally.

Many farmers grapple with tight labour markets, the increasing costs of production, price pressures from customers and increased demands on speed to market and product quality. By automating labour-intensive tasks such as oyster grading, farmers can reposition their competitive status while maintaining heightened reputational value through quality, consistency, and speed.

Immediate cost savings with oyster grading automation technology


Reducing costs that compromise quality never ends well. In the oyster and shellfish industry, product quality is a non-negotiable. Oyster farmers are continually experimenting with production processes to unearth cost-saving opportunities that don’t negatively impact the quality of their products.

By automating oyster grading, farms experience an immediate cost savings by eliminating draining labour costs without diluting the quality of the oyster.

The SED Graders oyster grader employs cushioned air technology that is gentler and safer on the live oyster than hand grading. Its other key benefits are speed and ease of use. It is a single-handed operation that replaces up to 13 experienced manual staff, grading, sorting, and bagging up to 24,800 oysters per hour.

The SED Grader Vision Grader uses high-tech video cameras to sort oysters by size instead of weight. This technology allows oysters to be sorted more accurately, which is important because markets are increasingly focused on size.

Using size-based grading is a better option than traditional weight-based grading. With conventional methods, a long and thin oyster would be graded the same as a short, wide oyster if they weighed the same. This can lead to wide tolerance margins and potential loss of value when selling. The SED Vision Oyster Grader, on the other hand, is designed and built for accuracy and profitability.
