Cereals processing technology

26 Cereals processing technology
to within the range 13 to 15% moisture, although malting barley may be dried to
around 12%. Storage temperatures and grain moisture content have a strong
influence on grain dormancy in barley, a condition which is highly important to
the maltster.
Drying systems either rely on near ambient air temperatures, or high
temperature driers. The former is a relatively slow process whereby the grain is
stored in bins or on the floor and is dried by forcing ambient, or slightly warmer
air through the grain. Batch and continuous flow high temperature driers rely on
air temperatures of between 40 and 120ºC with a necessity to cool the grain
before storage. Drying temperatures of grain destined for milling, malting or for
seed are more critical than for other uses.
