Comparison of the efficiency of different sets of lines for post-harvest treatment of cereals with regard to their energy intensity
 ŠTĚPÁNEK, Petr
The current energy crisis is having a significant impact on many industries around the world, and it is also significant in the Czech Republic. Apart from agriculture, the food industry, which is directly linked to agriculture, is also affected. The aim of this theses is to compare the efficiency and energy consumption of the post-harvest treatment process of spring barely, Bente variety. To compare the harvested and subsequently clean and properly postharvest treated barley grain, two different post-harvest lines equipped with a screen or aspiration grain cleaner were used. The grain was sampled in both cases in August 2022 and assessed for moisture, bulk density, HTZ, impurities and impurities. For the post-harvest lines, the energy requirements of grain cleaning was then calculated. The screen grain cleaner is more suitable for the removal of hea-vier components of the grain mass such as fractions. The aspiration grain cleaner is more suitable for the removal of lighter admixtures and impurities and its use is less energy intensive.

This Bachelor's thesis focuses on noise exposure of post-harvest lines operators. The main aim of the thesis was to determine the noise pollution in the workplace. The results of the measurement were mathematically processed and subsequently compared with the current Government Regulation no. 217/2016 Coll. amending Regulation no. 272/2011 Coll. on protection of health from adverse effects of noise and vibrations. Furthermore, the thesis includes noise control measures that protect the post-harvest lines operators from unwanted noise.
