Title Pneumatic machines and nut harvesting: Identifying systems restricting the emission of dust during harvesting

Abstract To meet the environmental hygiene problems of large amount of dust produced during the process of picking hazelnuts in Italy by means of turbo-aspirating machines, this research identifies suitable filtering systems. The main types of dust removers for medium-fine dusts were studied: a comparative examination showed that mechanical dust removal by cyclone (centrifugal dust separator) was the most effective. Two prototype filters were designed and built, each consisting of four cyclones with a diameter of 350mm and 250mm, respectively. Field tests showed that the 350mm cyclone had a dust removing capacity of 90%, with no reduction in performance caused by the dust going through it, while the 250mm cyclone removed 93.75% with a reduction in performance of approximately 30%. Though both filtering systems appear to be acceptable, the latter one allows a further reduction of 50% of the fine dust in the working environment. Summary in Italian, French, German, English and Spanish.
