Effect of Manipulation Technique on The Grains Quality in Post-harvesting Lines

Marek Angelovič

Abstract


Abstract

Experimental measurements during transporting and manipulating with grains were carried out at post-harvesting line under operational conditions. Measurements were carried out in Agro Division Selice and POD Abrahám. Effect of the transportation and manipulation on the external quality of grains was evaluated. Grain volume weight, foreign matters, impurities and grain damage were assessed. Obtained results: Manipulation with grain is a big source of grain mechanical damage. Bucket elevators are intended for vertical transportation of grain, they cause crushing the grain leading to breaking kernels rather than to small damages of transported grain. Chain conveyors (redlers) are intended for horizontal transportation of grain. The mechanical damage of grain is particularly observed at the capacity lower than the nominal capacity. Screw conveyors with closed channel are rarely used in post-harvesting lines. They cause large damage of transported grain and therefore absolutely improper for malting barley (sprouts are broken by them).
