30 t/h onion grading and packaging line

This 30 ton per hour grading line consists out of a receiving hopper which pre-cleans the newly harvested onions and places the product on a conveyor belt that transports the product to the 5 grid grid-grader.

From there the graded product is transported to 5 inspection tables. The undersized product and the dirt that falls out the bottom of the grid grader goes directly to a disposal bin.

The 5 graded sizes pass the inspection on their way to the semi-automatic weigher/baggers.
