The Tong vibrating length grader is most popularly used for length grading carrots and other long-shaped crops. Based on a simple yet effective design, the vibrating carrot grader offers an affordable grading solution. It will reliably perform under the most demanding carrot grading & handling environments.
The vibrating length grader is slightly different to the Lift Roller Grader, which grades carrots based on the width/diameter of the crop. The vibrating length grader gently vibrates to spread crop in a longitudinal orientation, across the machine’s stainless steel corrugated vibrating plates.
Fixed speed motor
Powered by a fixed speed motor, each vibrating plate is separated by an adjustable outlet. As crop passes along the vibrating plates, the longer crop passes over, resulting in shorter crop falling through the preceding incremental outlets. Each of the grades passes onto side projection conveyors. And any oversized crop passes over the end of the machine.
A popular carrot grader for throughputs of up to 10 tonnes per hour. The vibrating length grader comes in standard widths of 1.2m, 1.5m, 1.6m and 1.8m, with a choice of up to 4 grading outlets.
Infeed Spreader Section
In order to create a more even spread of crop at the infeed of the vibrating length grader, an infeed spreader section is available. This distributes crop across the width of the machine. Driven via its own independent motor, the spreader section consists of rotating rubber discs on one shaft. Helping to achieve higher accuracy of grading. Particularly when operating under higher throughputs.
Offering maximum flexibility in grade size, the crop outlets on the vibrating length grader are fully adjustable. Allowing you to set the outlet size to suit your exact requirements.
The vibrating length grader is built based upon a simple yet robust design. Offering and effective and somewhat economical solution for length grading carrots. Without the investment of an optical sorting machine.
