Roller grader SR is a highly versatile and efficinet machine used for diameter sorting of a wide variety of round and tubular vegetables, including carrots, potatoes, beets and onions.

The working elements of the machine are stainless steel rollers. As the rollers travel forward they rotate, turning the product for precise and product-friendly sizing.

In the working area of ​​the machine, the rolls are guided at two height levels. The basic height of the rolls is kept constant. Whereas, the height of every second roller is adjustable by an operator.

Sorting ranges are set by adjusting the distance between the levels of rollers at defined locations, along the length of the machine. Crops that fit in the spacing that is created between the rollers guided on two levels, fall throught the rollers and are carried away by conveyors for different product sizes. The height of the rolls is adjusted by means of a handle. The speed of the rollers' travel is adjustable by the means of an inverter.

Vegetables enter into the machine on a flat conveyor integrated with the machine. The width of the conveyor ensures even distribution of the product across the entire working width of the machine and its effective use.

As standard, the machine is equipped with a discharge chute.

Depending on the machine model, the grader can produce four or five sorts.

As standard, the structure of the machine is powder coated, while all elements that come into contact with food are made of acid-resistant steel or certified artificial materials.
