Buyers pay for clean, uniform grain, and discount foreign matter and damage.
What to remove
Dust and chaff, stones and soil, broken and shrivelled kernels, weed seeds and insect-damaged grain.
How
- Winnow or use a fan cleaner to blow out light material.
- Screen with sieves of the right size to remove fines and oversize.
- Hand-sort or use a gravity table for high-value lots.
- Re-check moisture after cleaning.
Grading
Learn the grade standards your buyers use (moisture, foreign matter, damage, colour, size) and sort lots to match. Keep grades separate; mixing a good lot with a poor one lowers the whole price.
Why it pays
Even a small improvement in grade can add more than the cleaning costs, and builds a reputation for reliable quality.
