Abstract
A grain dryer having a mixed-flow heating section, a tempering transition section, and a vacuum-cooled crossflow cooling section. A fan positioned on the end of the dryer creates a negative pressure in the cooling plenum that pulls air through the grain, warming the air while cooling the grain. This warmed air is pulled through the fan and then passed through a heater to bring it to appropriate drying temperature. This air is then pushed into a heating plenum, where it passes through a mixed-flow grain column, drying the grain, and then exhausted to ambient air.
Claims7
A grain dryer, comprising:
- a wet holding section in communication with a mixed-flow heating section;
- a tempering transition section having solid inner and outer walls adapted to prevent air from passing through the tempering transition section in communication with the mixed-flow heating section;
- a crossflow vacuum-cooling section in communication with the tempering transition section;
- an unloading section in communication with the crossflow vacuum-cooling section;
- a negatively pressurized plenum within the crossflow vacuum-cooling section, between the tempering transition section and the unloading section having a fan in communication with a heater;
- and
- wherein the tempering transition section is positioned between the mixed-flow heating section and the crossflow vacuum-cooling section and ambient air flows through the crossflow vacuum cooling section, is pulled into the fan, and then further heated by the heater.
