The VAKI Smart Grader delivers accurate fish grading while minimising the impact on your fish as they pass through the outlets. The dewatering unit distributes the fish evenly over the width of the grader, so all 10 tracks are used effectively.

Further the inclination of the main sorting unit can be adjusted from 5-10° with an electric actuator. The opening of the grader is controlled with electric linear actuators that can be manually operated from a control panel on the grader or automatically from the VAKI Counter which counts, size measures and calculates the split between the grades. The opening for each grade is displayed on a digital display. The grader is built in high grade stainless steel 316L and selected plastic materials that are corrosion and water resistant.
