Sizing Products

Tong’s lift roller sizer is ideal for almost any type of crop, offering high capacity, multiple sizing in one vegetable sizing machine.

Flexible in its use for a wide range of crops including potatoes, carrots, onions, parsnips, Brussel sprouts, celeriac, swedes and bulbs, the Tong lift roller sizer is manufactured based on grade band requirements and crop type, with the option of adjusting grade band settings to suit different crop varieties and sizes.

The Tong Lift roller sizer is an ideal sizing solution for achieving a variety of grade sizes, with up to 8 grade bands within one machine.

From carrots and parsnips to bulbs, potatoes, onions and swede, the lift roller sizer offers accurate sizing of a wide variety of crop.

Tong lift roller sizers are built to perform, offering gentle sizing of crop at high capacities from 10 – 50 tons per hour.

The Tong lift roller sizer is a popular choice for growers or packers handling crops which are not suited to screen sizing, making it a particularly popular choice for effectively sizing carrots and parsnips.

What makes lift roller sizing different is that vegetable sizing is performed by width/diameter using a series of forward moving vegetable sizing 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.

The lift roller sizer offers great flexibility with a wide choice of grade sizes to suit your specific needs. It is the perfect vegetable sizing solution if you are looking to size multiple crop on one sizing line as grade bands can be easily adjusted to suit different crop and contract demands.

For carrots, parsnips or daffodil bulbs the lift roller sizer is most commonly manufactured with varying grade sizes from 18mm to 88mm, for potatoes and onions grade sizes normally range from 30mm to 110mm. Standard grade band length delivers crop onto 600mm wide grade conveyors with an option for extended bands for higher throughputs.

So, whatever your crop type or sizing requirements, Tong has it covered and can custom-build a lift roller sizing system to suit your exact requirements.

All Tong Lift Roller Sizers are built with Tong’s Blue Inverter Technology, offering the very best energy efficiency and exceptional energy savings.

Now available as an option across Tong’s lift roller sizing 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.

A popular option on the Lift Roller Sizer 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 sizing machine. The spreader section is driven via its own independent motor and helps to achieve higher accuracy grading, particularly when operating under higher throughputs.
