1.1 The ripe onion should be graded in size by the vegetable grading machine. Then onions with big bulb, small stem, tight structure will be chosen.
1.2 Next, remove onion outer leaves, tops and roots by onion peeling & root cutting machine.
1.3 After removing the tops, roots and outer integuments, onions are cut into slices by slicing machine. The thickness of slices should be 3-5 mm and they need a full washing.
1.4 After cleaning, put onion slices into the dewaterting machine to remove the surface water.
1.5 Preheat the drying machine to a temperature of 60 ℃, and spread the onion slices evenly on the trays of the drying machine for dehydration. The drying temperature should be 55-60 ℃, drying time should be 6-7 hours. When the moisture is reduced to ≦5%, the drying process is finished.
