Critical air velocity as a separation feature in nuts of European beech (Fagus silvatica L.)
Paweł Tylek | Józef Walczyk
anglais. Stands of European beech cover around 4.1% of the total forest area in Poland. In the Carpathians the share of European beech amounts to 25.9%. Long intervals between mast seed years in beech force foresters to optimize the seed management. The separation of seeds into various quality classes is usually done with devices working on the basis of physical properties of seeds. The goal of this work was to analyze the critical velocity of beechnuts in order to determine, if the aerodynamic properties of beechnuts can be used as a basis for their separation. The other goal of this work was development of an algorithm of computer-aided image analysis.
