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.
