PNEUMATIC CONVEYING CHARACTERISTICS OF SOYA BEAN.

In this research, the pneumatic conveying characteristics of soya bean (Glycine max L.) of Atakisi variety were determined. The length, width, thickness, arithmetic mean diameter, geometric mean diameter, sphericity, volume, thousand seed mass, bulk density, true density, porosity, projected area, terminal velocity, drag coefficient, pressure drop, power consumption, and seed damage, namely mechanical damage, germination test, and seed vigour index were investigated experimentally. The positive low pressure system was used for conveying of soya bean. The power requirement and pressure drop increased with increase in revolution of blower and conveying capacity decreased with increase in pipe diameter. The highest pressure drop and power requirement were obtained for 54.5 mm pipe diameter, while the lowest pressure drop was found for 70.3 mm pipe diameter. The mechanical damage to the soya bean for both pipe diameter increased as the revolution of blower increased. [ABSTRACT FROM AUTHOR]
