Abstract

In some parts of the world, eg China, maize reaches a grain dryer at low temperatures, frequently in the range of -10°C to -20°C. The effect of a low grain temperature, and an equally low ambient temperature, was determined, partially by experimentation and partially by simulation The percentage of moisture frozen in maize depends on the grain moisture content and temperature. The low grain and ambient temperatures surprisingly have only a small effect on dryer capacity; however, the influence on the energy consumption is large.
