Oyster farmers around the world recognise the SED Graders vision oyster grading machine as one of the most advanced and accurate oyster grading machines available.
Developed in collaboration with oyster farmers, the vision oyster grading machine is manufactured in Tasmania, Australia, using the highest quality stainless steel and built to last for years.
The vision oyster grading machine is an all-in-one system that separates, cleans, measures, sorts, counts and bags. SED Graders has also developed a highly efficient overcatch treatment, utilising a cold shock hypersaline bath that greatly reduces mortality rates.
The overcatch treatment is a seamless addition to the vision oyster grading machine that adds significant value to oyster farmers throughout the harvest cycle.
The vision oyster grading machine employs cushioned air scientifically proven to be far more gentle on the oyster than sorting by hand. More importantly, the vision oyster grading machine significantly improves productivity. The vision oyster grading machine processes from 14,400 to 28,800 oysters per hour. Designed for single-handed operation, the vision oyster grading machine does the work of 13 experienced graders.
South Australian oyster farmer Max Lowe says,
“The SED Vision Grader has taken our business to the next level; we now produce more oysters for less money.”
Fully customised to suit your farming operations, you can optimise the vision oyster grading machine to include four, six, or eight grade exits and set the size and number of bags according to your output. With an accuracy rate of 99% and designed for easy operation, and with worldwide after sales support, the SED Graders vision oyster grading machine is one of the best investments your farm can make.
The SED Graders water oyster grading machine is the ideal solution for seed and juvenile oysters
For seed and juvenile oysters, the high mortality rate is a concern. In many instances, the mortality rate from seed to saleable oysters can be as high as 45%. In any other primary producer environment, such a high mortality rate of any stock or crop on a regular cycle would be disastrous. It was this statistic that inspired the creation of the SED Graders water oyster grading machine.
Specifically designed to lower the mortality rate when handling and grading seed and juvenile oysters, the improvement in mortality rate has enabled many farming operations to reduce their mortality down to as low as 1.5%.
The SED Graders water oyster grader machine replicates juvenile oyster underwater behaviour to gently grade, with far greater accuracy. This removes oyster stress caused by traditional barrel and shaker graders, as well as the high cost and laborious work of hand grading. The gentle action of the underwater grading successfully grades out dead oysters, allowing farmers to on-grow and sell the remaining live oysters.
On average, the water oyster grading machine grades 100,000 oysters sized from 20-30mm every hour, and a twin barrel machine will double this figure. Rates are faster with smaller oysters and a second lane will increase productivity. The water oyster grading machine is fully automatic and is a single person operation. The machine automatically sorts the oysters underwater into three sizes and delivers the oysters to collection points via three small conveyors.
When used with the in-feed options and baggers, the machine empties the oysters into a bulk hopper, from where it washes, measures and separates them into grades.
The water oyster grading machine integrates with the SED Graders vision oyster grading machine, providing a comprehensive automated oyster grading solution.
