The task was to build a high-quality, reliable and flexible grading system with the possibility to work in a variety of different modes. Because the system has to cope, with a variety of different shapes of vegetables, a flexible solution was required in order to handle different purposes.

Therefore, a special solution based on Skals standard components was designed. The system consists of an installation with a hopper – inlet for trucks, boxes and bags. From this point all of the products go directly to cleaning and inspection. Once the potatoes are manually inspected, the customer is able to choose, whether the products should go directly to the washing machine or to the grading and forward to the washing proces or to the boxes. The box fillers are equipped with automatic shifts, allowing the system to continue to run, even while shifting boxes.

Combining multiple functions within one grading system
The system allows the customer to either simply grade or grade and wash the products and to send unwashed and washed products from the packing line into boxes. Furthermore the system allows the customer to choose between filter drying or polishing.
In addition the grading system is prepared for the handling of onions. The ability to adapt the grading system to different vegetables to certain actions, was one of the main advantages in Skals’s offer.
