Grading is done through sieves or grating. This way of grading is simple and compact, but requires products that hard compact and with a firm skin.

Sizing the product through stacked grids

Grading with vibrating stacked grids is the simplest way to size onions, potatoes and other, more or less, round products.

The system is compact and can handle big capacities.

But this system treats the product rather roughly, therefore it requires a compact and sturdy product.
