Calculate the paddy throughput needed for your working day. Adjust the assumptions to reflect your own operation; the result is a planning target, not a verified machine specification.
MINIMUM PADDY INPUT CAPACITY
8.0 productive hours per day
Planning range: 750–844 kg/h
Includes a 20–35% planning reserve.
An N90 may be close to its working limit. Verify sustained output and compare larger or two-stage options.
Suitability bands are indicative planning rules, not product ratings.How the calculation works
Productive hours = scheduled hours × utilization ÷ 100.
Minimum hourly capacity = daily paddy weight × peak factor ÷ productive hours.
The planning range adds a 20–35% reserve above this minimum. These percentages are editable planning assumptions in the calculation code, not a manufacturer’s recommendation. All results are paddy input, not finished-rice output.
Why utilization matters
Loading, cleaning, adjustment and minor stops consume time. The default example is 5,000 kg/day, 10 scheduled hours and 80% utilization, giving 625 kg/h before a reserve. Replace those inputs with your records.
Can an N90 meet this target?
Compare the result with the confirmed working output of the actual configuration. At higher targets, assess a larger machine or more productive hours. If whole-grain quality is the main goal, also compare two-stage or multi-stage equipment.
