SOME PHYSICAL PROPERTIES OF SAFFLOWER SEED (CARTHAMUS TINCTORIUS L.)

Abstract

Some physical properties of safflower (Carthamus tinctorius L.) were determined as a function of moisture content. Also, physical properties such as dimensions, geometric mean diameter, sphericity, 1000 seeds mass, bulk and seed density, terminal velocity, projected area and porosity were measured at three moisture content levels (5.61 %, 14.08 % and 23.32 d.b. %). The values of length, mass, geometric mean diameter, sphericity, bulk density, seed density, terminal velocity, projected area and porosity were established as 6.89-7.56 mm, 0.035-0.054 g, 4.13-4.70 mm, 0.600-0.623, 526.9-488.6 kg m^-3, 1096.7-1187.6 kg m^-3, 3.84-5.02 ms^-1, 24.60-27.50 mm² and 52.0- 56.7%, respectively. The coefficient of static friction on an iron sheet and a galvanized sheet were established.
