SIZE CROP BY DIAMETER
The Tong lift roller grader is a popular choice for growers or packers handling crops which are not suited to screen grading, making it a particularly popular choice for effectively grading carrots and parsnips.
What makes lift roller grading different is that vegetable sizing is performed by width/diameter using a series of forward moving vegetable grading rollers; one bed of fixed bottom rollers, and a top bed of height adjustable rollers. Every second roller is mounted in poly-guide plates, which allows them to lift vertically to make a specified grade size.
FEATURES
BLUE INVERTER TECHNOLOGY
All Tong Lift Roller Graders are built with Tong’s Blue Inverter Technology, offering the very best energy efficiency and exceptional energy savings.
AUTO-TOUCH HMI CONTROL
Now available as an option across Tong’s lift roller grading range, Tong’s Auto-Touch HMI controls allow grade bands on the machine to be altered in seconds, at the touch of a screen. This intelligent control option significantly improves ease of use, as well as throughput volumes and handling speed by simply removing the need for more time-consuming manual adjustments.
On standard models, changing of the grade bands is performed by adjusting roller settings manually. However, when specified with the latest Auto-Touch HMI controls, roller settings can be changed instantly and automatically, making adjustments even easier for users. What’s more, the HMI touch screen control unit can be set with pre-determined programs, each with a different combination of grade bands set to suit different crop and contract demands. With the option to select any one of the programs within seconds this, allows users to switch between crop varieties and contracts within minutes, offering huge savings in time, labour and costs.
INFEED SPREADER SECTION
A popular option on the Lift Roller Grader is an infeed spreader section of 6 rubber-covered rollers to do exactly what the name suggests; spread crop evenly across the width of the grading machine. The spreader section is driven via its own independent motor and helps to achieve higher accuracy grading, particularly when operating under higher throughputs.
