Analysis of Dried Onions in a Hybrid Solar Dryer, Freeze Dryer and Tunnel Dryer

open access: yesChemical Engineering Transactions, 2015
Onion (Allium cepa L.) belongs to the lily family, such as garlic and leeks. Dehydrated onion can be presented in powder, chunks, granules or slices. Its applications consider manufacturing of condiments, dehydrated or added to rehydrated meals. We determined the drying curves of onion slices cut into 10 and 5 mm thickness, using a hybrid solar dryer ...
