VAKI Drum Grader
The VAKI Drum Grader is a rotary drum grader which has a drum formed of equally spaced 16 mm rods that make up a cone. The fish is pumped in on the narrow end of the cone to the internal side. A continues flow of water gently pushes the fish down along the rods and when the space between to rods is equal to the fish thickness it falls through and into the outlet chute.

What our Customers say
“The Drum Grader from VAKI has increased our grading efficiency a great deal. We are very pleased with the possibility to grade in three categories instead of the usually two, as with the old hand grading system (the box grader). The grader is very gentle to the fish and is pumped into the grader instead of netting/ and handling as it is done with the old method.
Also important is the saving of time and manpower. Before we had two to three people grading by box, but now we only need one person grading when using the Drum Grader. We find the grader really easy to work with and compact, that gives us the possibility to move it around and grade where ever we want. We find the benefits of the new Drum Grader quite big”.
