Experimental Research on Microwave Field and Hot Air Drying of Barley Seeds

The purpose of these experiments was to find optimum conditions based on the influence of microwave / hot air heating on barley seeds with high humidity. Parameters variation, temperature, humidity, power in the drying process were analyzed. The effects of microwaves on the drying characteristics were studied in two cases: the first case uses a constant microwave power and hot air jet at 55°C±10%, without taking into account the maximum allowable temperature in the seedbed, and in the second situation, variable power is used to ensure that the temperature does not exceed 65°C. The experiments were carried out on barley seeds, the Thuringia variety. To see and study the influence microwaves have on microwave field treated seeds, in the two above-mentioned cases, barley grains were germinated and the daily progression of the germination process was followed.
