Abstract
The energy required for harvesting and drying of shelled corn was estimated using the potential workable number of days for a grain-maize combine harvester predicated on the drying rate and the rate of harvesting in the paddy field areas. A harvester with an attached maize header and far-infrared radiation grain dryer for 14.4 m3 of shelled corn drying were used. The results of the simulation show that the moisture content of the shelled corn alters the duration of the process from 2 days to 1 day with 3 driers owned by a corporate farm versus 4 driers owned by 4 family farms. From the relationship between the moisture content at the start of the harvest of the corn and the total energy consumption, the energy required in the harvesting and drying processes increase when the moisture content of the shelled corn decreases below 30％. However, it was found that the energy required in the harvesting and drying processes decrease when the period of the process changes from 2 days to 1 day.
