QUIZ – drying canola

Three questions on safe drying temperatures, airflow requirement for in-bin drying, and how to improve airflow in large bins.

1. What is the maximum recommended drying temperature if canola is damp (over 12.5% moisture) and the dryer does not mix grain during the drying process?
2. To dry canola in a grain bin using natural air or heated air through aeration fans, what is the recommended minimum airflow in cubic feet per minute per bushel (cfm/bu)?
3. Continuing on the air flow theme... A Prairie Agricultural Machinery Institute (PAMI) study showed that a standard, single phase 10-hp centrifugal fan could not push air through a full 25,000-bushel bin of canola. What did the study suggest was an appropriate fill level to achieve sufficient airflow to dry canola?
