Field Implementation and Model Validation of a Model-Based Fan and Burner Control Strategy for the In-Bin Drying and Conditioning of Corn
2007
Bartosik, R.E. | Maier, D.E.
A new model-based self-adapting variable heat (SAVH) fan and burner control strategy for the in-bin drying and conditioning of corn was successfully implemented in three field experiments during the 2004 drying season. These experiments were carried out in three different locations throughout Indiana, in bins with different capacities (from 57 to 431 tonnes) and with two different corn types (yellow dent and white corn). One continuous natural air (CNA) experiment was also carried out drying yellow dent corn in a 57-tonne bin. The SAVH control strategy was able to successfully dry wet corn to a final moisture content (MC) close to 15%, with a relatively uniform final MC in the entire grain mass. Compared to the CNA strategy, the SAVH control strategy successfully avoided the overdrying of the grain under the same weather conditions.
