Description: The presence of dockage and fine materials in a stored grain bulk influences the grain quality management. For example, the distribution of dockage inside stored grain bins is not uniform throughout grain bulk, so different locations exhibit different resistance to airflow leading to non-uniformity in aeration and grain drying. Distribution of dockage and fine materials inside a farm bin filled with hard spring wheat (grade No. 2) was studied. The farm bin (10 m diameter and 11 m height from the floor to the top vent) was filled from the top vent using a grain auger. After filling, wheat samples were collected from 13 locations inside the bin, nine locations along a diameter of the bin from one end to another and four locations along the perpendicular diameter. The collected samples were then separated into three fractions by sieving: wheat grains, dockage larger than wheat (coarse materials), and dockage smaller than wheat (fines). The percentage of coarse and fines by weight was higher near the wall than the corresponding locations towards the centre.
