Description: Farmers and managers of grain storage facilities in Canada turn grain to reduce the rate of deterioration of the stored grain. Turning stored grain is the movement of grain from one bin into another bin and sometimes back into the original bin. Mixing breaks up warm, moist, mould or insect-infested pockets of grain in the bin and spreads them throughout the bulk. The average temperature of the grain bulk is normally not reduced during turning (Watters 1963), but the temperatures of all parts of the grain bulk tend to come near the average temperature of the grain bulk so that both high and low extremes are eliminated. The mixing action reduces extremes of moisture content, although individual kernels maintain extreme moisture contents for some time (White et al. 1972). Thus, in eliminating those niches of high temperature and moisture content which normally serve as foci for microbial and arthropod infestation, the grain bulk becomes less vulnerable to deterioration.
