Barley grain pre-drying by using low energy laser beam

A laboratory laser beam drying method for barley grains is presented and the corresponding energy transfer is analyzed. Barley grains were illuminated from one side during a period of 60 seconds with 100 mW 650 nm and 200 mW 650 nm collimated laser beam. The intensity of laser radiation within the illuminated area was 12.74 Wsm-2 for a 100 mW laser and 25.48 Wsm-2 for 200 mW laser. Barley grain samples with 18, 20, and 25% moisture contents were used for the analysis. Obtained results showed differences in energy consumption among grains with different initial moisture content. The energy savings of 51%, in laboratory conditions, compared to convective hot air drying, are determined by using 100 mW laser on the grain samples with 25% of moisture. Also, energy savings depend on grain wet basis and decrease with decrease of moisture content.
