dryer wet bin — The compartment that maintains an adequate level of wet grain to ensure proper air seal.
Perforated to allow the grain to be preheated, the dryer wet bin is also where the wet sensor is situated.
The dryer wet bin is located at the top of the dryer.
drying capacity — The flow rate of the grain (generally expressed in bushels per hour) as it flows through
the dryer over a specific range of moisture removal. For example, when going from 25% to 15% moisture,
the drying capacity is the bushels per hour dried over the removal of the 10 points of moisture. Drying
capacity is dependent on several factors, namely the moisture of the wet grain, drying temperature, and
the size of the dryer.
drying mode — The process by which wet grain passes through the dryer and exits as dry grain. There
are two available drying modes in a portable dryer application: continuous flow and staged batch. Also
referred to as moisture control mode.
dry sensor — The sensor that measures the dry grain’s moisture content and displays the readings
onscreen. To avoid grain spoilage and other potential issues that might result from inaccurate readings,
the dry sensor readings should be validated regularly. The dry sensor is located in the grain discharge box.
full-heat — A grain drying operation where the grain is unloaded hot, not cooled, and dedicated external
bins are required for slow cooling. Drying capacity is significantly higher with full-heat than with dry and
cool. Full-heat is mostly used for drying corn.
grain column — The column upon which the grain travels down. On a portable dryer, each grain column
is 2 ft (61 cm) wide. See also
in-storage cooling — A grain cooling process that requires hot grain to be discharged from the dryer at its
target moisture content, placed in a storage bin where it is immediately cooled, and then left there to store.
Although similar to dryeration, in-storage cooling is a faster process because it eliminates the tempering
phase and the need for extra handling equipment. Also referred to as bin cooling.
load auger — A helical-shaped device that ensures that the dryer is filled uniformly. When the load auger
rotates, the grain moves along the auger’s spiral to evenly fill the dryer wet bin.
load auger fill switch — A limit switch with integrated microprocessor that is activated when the dryer wet
bin is full. Once activated, the load auger stops rotating and the wet grain storage bin stops supplying wet
grain to the dryer. The load auger fill switch is located in the dryer wet bin.
load delay — The time from when the dryer detects available space in the dryer wet bin; that is, when the
level of wet grain drops below the load auger fill switch, to when the loading mechanism is activated. The
load delay only works in auto mode.
loading mechanism — A system of components consisting of the load auger and the auxiliary equipment
that feed grain to the dryer wet bin. Considering that loading mechanisms are available with varying speed
