Microprocessor controlled low-temperature corn drying system
Abstract Hardware, software and control criteria of microcomputer control of low-temperature corn drying are discussed. The ambient temperature and relative humidity were monitored by the microcomputer as a measure of the input conditions. A model of the low-temperature drying process stored in the memory enabled the microcomputer to calculate the grain moisture contents at assigned locations in the bin. Control decisions were then based on predicted moisture levels and on predicted or measured grain temperatures. Simulation results showed that the proposed system can save energy from 5 to 31% compared with high-temperature drying, depending upon the weather conditions.
Thin-Layer Drying and Rewetting Equations for Shelled Yellow Corn
ABSTRACT THIN-LAYER drying and rewetting data for shelled yellow corn have been compiled from all available sources. A thin-layer drying equation was developed us-ing these data with air temperature, air humidity, air velocity and corn initial moisture content as the indepen-dent variables. A thin-layer rewetting equation was also developed. The equation contains air temperature, air humidity and corn initial moisture content as the in-dependent variables.
