The Tong Vibrating Length Sizer is most popularly used for length sizing carrots and other long-shaped crops. Based on a simple yet effective design, the vibrating carrot sizer offers an affordable sizing solution, and will reliably perform under the most demanding carrot sizing & handling environments.

The Vibrating Length Sizer is slightly different to the Lift Roller Sizer, which sizes carrots based on the width/diameter of the crop. Instead, The Vibrating Length Sizing machine gently vibrates to spread crop in a longitudinal orientation, across the machine’s stainless steel corrugated vibrating plates.


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 sizes passes onto side projection conveyors, and any oversized crop passes over the end of the machine.

A popular carrot sizer for outputs of up to 100 tons per hour, the Vibrating Length Sizer comes in standard widths of approximately 3 ¾ ft., 3 ¾ ft. and 5 ¾ ft., with a choice of up to 4 sizing outlets.

Infeed Spreader Section

Infeed Spreader Section

In order to create a more even spread of crop at the infeed of the vibrating length sizer, 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 which help to achieve higher accuracy of sizing by spreading crop evenly prior to sizing. This is particularly effective when operating under higher outputs.

Adjustable Outlets

Adjustable Outlets

Offering maximum flexibility in grade size, the crop outlets on the vibrating length sizer are fully adjustable. This allows you to set the outlet size to suit your exact requirements.
