Influence of Physical and Mechanical Properties and Condition of Barley Grain on Damage During Mechanical Processing

Abstract

To assess the extent of injury of barley seeds by the working parts of agricultural machinery, it is suggested to check their germination using an aeroponics device along with ways of visual control of the amount of mechanical damage. On the basis of the carried out experimental researches impact of traumatization on germination of seeds of barley depending on its physical and mechanical properties and a condition of grain material is established. The experimental dependences are given, according to which the extremum is observed -the maximum value of germination in the permissible range of variation of moisture content for different values of the number of grain passes through the machine. Keywords-grain, barley, damaging ability of machines, technological line, mechanical damage, laboratory germination of seeds, number of grain passes through the machine.
