Discussion
A deep bed dryer produces grain at 12 per cent at the bottom and 19 per cent at the top of the bed.
Which change addresses the problem most directly?
Answer: D
Correct answer: Reduce the bed depth or recirculate
A seven-point spread between bottom and top is the signature fault of a deep bed: air gives up heat and takes up moisture as it rises, so it reaches the upper layers cooler, more humid and nearly spent. Reducing the depth, or recirculating the grain so every kernel spends comparable time near the inlet, attacks the cause directly.
Raising the air temperature would over-dry the bottom further before helping the top. Increasing the depth makes the spread worse - it grows rapidly with depth - and reducing the air flow leaves even less drying potential for the upper layers.
