The proof is in the numbers


Our state-of-the-art oyster graders are fast, precise, and gentle, enhancing productivity by up to 400%. Designed to meet the demands of modern oyster farming, our fully automated oyster graders streamline operations, cut labour costs, and minimise product damage and mortality rates associated with manual grading.

Here’s the evidence:

Our flagship product, the SED Graders oyster Vision Grader, seamlessly sorts, measures, cleans, counts, and bags fully grown oysters at an astounding rate of 4 to 8 oysters per second, depending on size and shape.

That’s equivalent to 14,400 to 28,800 oysters per hour – a feat that would require thirteen manual workers. The Vision Grader can be operated single-handedly.

With a count accuracy of up to 99%, our SED Graders oyster Vision Grader ensures your oysters are market-ready.

Our SED Graders juvenile oyster grader is a game-changer for juvenile oysters, grading up to 100,000 per hour, even faster for smaller oysters. By significantly reducing mortality rates to just 1.5%, our juvenile grader offers a lifeline to oyster farmers during disease outbreaks. During severe disease outbreaks, local farmers reported saving 40% of their oyster crop with our technology.

Whether you’re in North America or Asia, our innovative oyster grading solutions are tailored to maximise efficiency and profitability for your business.
