COSTA, Eduarda Ribeiro. Evaluation of wood chip fed dryer and soybean grain quality. 38p Monograph (Bachelor of Agronomy Course). Federal Institute of Education, Science and Technology Goiano – Campus Rio Verde, Rio Verde, GO, 2021.

The present work was developed in partnership with private companies Caramuru Alimentos S/A and Comber LTDA and supported by Federal Goiano Institute - Campus Rio Verde, with the objective of evaluating the performance of the drying of soybeans, using a dryer with a furnace automatically fed with eucalyptus chips, as well as how to evaluate the quality of soybeans before and after drying. Twelve samples were collected before drying and another 12 samples after drying, totaling 24 samples of around 1 kg each, at intervals of 5 minutes, during the drying process. The following experimental evaluations were carried out: dryer – performance, heating power and fuel consumption. The grains were evaluated for moisture content, electrical conductivity, apparent specific gravity and mass of one thousand grains. The drying was carried out in a mixed flow dryer with a nominal capacity of 100 tons per hour. The temperature and relative humidity of the ambient air were monitored using a data logger. Drying air, intergranular air and exhaust air temperatures were measured using thermocouples coupled to digital temperature indicators and using an infrared thermometer. Average fuel consumption was 21.78 kg of chips per ton of dry grain. The specific energy consumption to dry 1.0 kg of grains was 11,871.80 kJ. In general, drying did not compromise the final quality of the soybeans.
