Corn kernel heat capacity
WebHigh-capacity drying equipment requires major initial capital investment, and incurs significant operating costs because of the large amounts of energy needed to operate … WebFor example, corn might be dried from 28 percent to 20 percent moisture content on the first pass through the dryer. The corn could be cooled and stored as long as an entire winter at 20 percent moisture. In addition to reducing the potential for heat damage to the kernels, dryer capacity (bushels per hour) is greatly increased when the corn is ...
