Abstract

The aerodynamic, physical and mechanical properties of lentil seeds commonly used in harvesting and processing systems in air conditioning and transfer systems by airborne fluid. To perform the compressive test, In order to pressure test the press-traction tester STM-20 manufactured by Santam engineering design was used. The used test device in this experiment was equipped with a DBBP-100 model BONGSHIN load cell. In this research, the speed of the two lentil cultivars, called bilesavar and Kimia, in three levels of size, medium and large and in four levels of moisture for bilesavar ( 9, 11, 5, 12 and 14) and for kimia (12, 5 / 13, 15 and 5/16) were studied on the basis. To analyze the experimental data, completely randomized design was used and Duncan multiband tests were used to compare the means. The aerodynamic properties tests indicate that the main effects of moisture content factors are significant at 1% probability level in Bilesavar cultivar. The main effect of grain size is significant at 5% probability level and the interaction between moisture content and grain size is not significant at the speed limit Is. As the humidity increases, the speed of the grain increases. So that the lowest amount in the humidity is 9.5%, it is 4.56 m/s. The highest amount in the 14% moisture content is equal to 7.962 m/s. In the kimia cultivar, the main effect of grain size is 1% and the main effect of moisture content on the speed limit is not significant and the mutual effect of moisture and grain size on the lentil's speed is significant at 1% probability level. By increasing the moisture content of the lentil grain, the speed limit has increased, with the highest amount for the size Coarse lentil seeds with a moisture content of 15% and 7.783 m/s and the smallest amount of lentil seeds in the moisture content of 16.5% is 6.067 than the second.
