10.1 INTRODUCTION
Aeration efficiency includes uniform air distribution through the stored product, sufficient airflow to maintain temperature and moisture, and minimal energy loss due to improper selection of fans, motors, and ducts. Aeration systems may perform less efficiently than originally planned, and low system efficiency often goes undiscovered until long periods of aeration have failed to produce the desired cooling results. Many factors may be involved in the malfunction of an aeration system. The main problems are faulty system design, improper system operation, excessive dockage accumulation in certain regions of the grain bulk, faulty fans, or gradual duct blockage by foreign material and fines.
