Why is rice mill output low?
First define output: paddy processed per hour and finished rice per hour measure different things. Check feed availability, stoppages and bottlenecks before judging the machine against a stated capacity.

Quick diagnosis
| Symptom | Possible cause | How to check | Recommended action |
|---|---|---|---|
| Mill waits for grain | Upstream interruption | Log feed gaps | Investigate the upstream supply |
| Frequent stops | Downtime | Record start and stop times | Address the repeated stop reason |
| One stage accumulates material | Local bottleneck | Observe the guarded flow path | Review that stage’s documented limits |
| Paddy rate is steady but rice rate falls | Recovery or measurement change | Compare input and all output weights | Reconcile the batch balance |
Measure a timed run
Record the input mass over a defined period. State whether downtime is included. A daily average and an uninterrupted running rate are both useful, but they answer different questions.
Check the whole line
A high-capacity machine cannot remove an upstream supply limit or a downstream handling constraint. Record where material accumulates and where machines wait.
Inspect only after isolation
If blockage or component condition needs inspection, stop and isolate according to the manual. Do not increase feed to overcome a suspected obstruction.
Plan capacity with utilization
Use daily paddy demand, available hours and target utilization in the capacity calculator. The result is a planning estimate; validate it against the complete line and the required finished quality.
Do not do
Do not compare white-rice output to a paddy-input rating. Do not assume a larger motor fixes a process bottleneck. Do not exceed permitted machine settings to meet a daily target.
Keep a useful record
Log input, operating time, stops, output fractions and batch identity together. That record separates sustained capacity issues from changes in grain quality or schedule.
Check your batch with the milling yield calculator.
