Machining effect of the blade position and rotor speed of centrifugal separator on Grape Marc
separation performance
Alessandro Leone
University of Foggia, Italy
The use of a centrifugal separator was evaluated to
separate the seeds from fresh marc after wine making
process and to identify the best setting of the machine. Five
different reels speed rotation (480, 576, 687 and 842rpm)
and two different blades adjustments (Type-A blade = 1.5
mm and Type-B blade = 8.5 mm) have been evaluated, at
the same mass flow rate (350kg h-1). Results showed that
using a centrifugal separator for the seeds separation from
the fresh grape marc is possible, reaching by setting the
optimal rotation speed of the reel (480rpm) and the best
distance between blades and cylinder (8.5mm - Type-B blade).
Speaker Biography
Alessandro Leone is an Associate Professor in agricultural mechanics and food
processing plants, SAFE department, engineering area, University of Foggia, where
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
