This work presented a review of energy requirement for drying sliced agricultural crops in order to produce high quality and shelf-stable products. Work on the estimation of energy requirement for drying different sliced crops such as potato, carrot, garlic, onions, mango, banana, apple, tomato etc. and factors affecting their energy requirement were reported. From the review, programming models for drying sliced fruits, as well as different empirical equations adopted by some researchers for estimating the energy requirements of different sliced crops at specific drying parameters were reported. Obtained results showed that crop functional characteristics, initial and desired moisture contents, slice thickness, air temperatures, specific heat capacity,... |
