n this paper an industrial combined plant assembled by a
low frequency ultrasound device, a microware apparatus
and a heat exchanger were employed and implemented in an
industrial olive oil plant to improve the conditioning of the olive
paste. Four different conditioning conditions were compared
to the traditional one. The extractability index (E), rheological
parameters and olive oil quality were determined. The use of
only the heat exchanger for the conditioning of the olive paste
leads to a lowvalue of extractability. By placing in series the heat
exchanger and the traditional malaxed, it is possible to obtain
the same quantitative performances, reducing the conditioning
timefrom40minto20min.Byusingamicrowavesysteminseries
with a heat exchanger, it is possible to reduce the conditioning
time considerably to just 4min, obtaining an entirely continuous
process. Combining heat exchanger, microwave, ultrasound an
slight increase of extractability was found. Finally the use of
alternative conditioning technologies, alone or in combination,
are able to save the lipophilic antioxidant furniturewhile, on the
contrary, brought to a reduction of hydrophilic antioxidant. The
cavitationeffect of ultrasound is able toovercome this drawback

he teaches mechanics and mechanization in agricultural, food engineering and
work safety. His major research topics are, in food processing plants: agro-food
industry plants and process settings, processing logic control, recovery of agro-food
waste by-products to useful composts in agriculture, as well as waste management
and in agricultural mechanics: Analysis of the vibrations transmission mode from
the vibrating heads to the trunk of olive trees and subsequent optimization; study,
design of mobile elevating work platforms; safety devices on tractors and machinery.
