How to solve farming problems

For well over two decades, the team at SED Graders has focused on how to solve farming problems for the oyster farming community in Australia and internationally.

Engineering and customising world-leading oyster grading machines that automate the grading process and create significant labour cost savings, improved consistency and enhanced speed to market have resulted in our clients reporting significant gains that directly impact their farms’ bottom line.

Taking the right steps ensures a tailored solution to solving complex problems


At SED Graders, our decades of experience have taught us that no two oyster farming operations are the same. Location, size, existing infrastructure and physical assets, logistical issues and of course access to seasonal staffing at grading time create their own unique challenges.

By automating the grading process, SED Graders problem solves these issues. We take a systematic approach to each farming system and design and manufacture a tailored solution.

We review all the relevant data and identify patterns and correlations that influence the farm’s oyster grading operation. Our engineering team designs a customised automated solution that maximises the way your farm processes its oysters.

The design phase is a collaborative process and we provide scaled drawings that illustrate how the machine will fit into your processing facility and make any necessary revisions prior to construction.

It is our level of attention to detail and understanding of your particular requirements that set the automation up for success.

Once the solution has been custom built at our facility in Tasmania, Australia, the oyster grading machine is transported to your site, anywhere in the world. The solution is installed and tested by our leading technicians and comprehensive training is provided to ensure all necessary staff and operators are fully confident in the machine operations.

Our after-sales support is second to none, and using our exclusive TeamView online video support system we can solve any technical issue remotely with a 100% strike rate.

We design and manufacture future-proofed customised automation systems and equipment


Our service doesn’t end with supplying the vision grading or water grading automation solution. We offer a complete range of auxiliary equipment, including basket systems,  hoppers and bins, conveyors, washers and drums.
