Average intake alone can hide a receiving bottleneck. Compare the harvest rate with the flow needed to unload one truck in the chosen time. The smaller conveyor, intake, distributor or downstream path can limit the whole route. Active unloading time excludes truck positioning, weighing and sampling. A pit can buffer a short surge, but it cannot cure a daily capacity shortfall. Confirm boot location, inlet arrangement, routing and interlocks against the exact elevator installation manual.

Multiply bushels by the selected cfm/bu target to get required airflow. Then choose a fan that can deliver that airflow at the expected static pressure for the crop, depth, floor, transitions and ductwork. Horsepower alone does not establish delivered airflow. Deeper grain generally increases resistance. An aeration target for keeping dry grain in condition is not automatically sufficient for natural-air drying. Use manufacturer fan curves and the correct crop resistance data.
Wet grain accumulates whenever receiving exceeds drying. The planner follows that inventory through the receiving and drying day, then carries any unfinished grain into the next harvest day. A balanced dryer can catch up outside receiving hours. An undersized dryer leaves a growing daily backlog; simply adding a wet bin does not remove that bottleneck. The outage allowance estimates extra volume only. Safe holding time depends on moisture, grain temperature, condition and aeration.
