Size Classification
Why Seed Grading Matters
Uniform seed size improves downstream processing consistency. Proper grading and screening help maintain stable production flow and enhance final product quality.
Improve Material Uniformity
Uniform seed size improves downstream processing consistency and ensures even heat transfer during roasting and pressing.
Increase Production Efficiency
Proper grading helps maintain stable production flow and reduces bottlenecks in continuous processing lines.
Improve Equipment Performance
Well-classified materials reduce processing interruptions and protect dehullers, roasters and oil presses from uneven loads.
Enhance Product Quality
Screening removes oversized and undersized particles, delivering cleaner feedstock for oil extraction.
How It Works
Working Principle
The vibrating screen uses vibration and multiple screen layers to separate materials according to size — delivering accurate classification for oilseed processing lines.
Raw MaterialSeeds enter from upstream cleaning or storage
FeedingEven distribution across screening decks
Vibrating ScreeningMulti-layer vibration separates by particle size
Size ClassificationOversized, standard and undersized fractions collected

Four short demonstrations show the feed, screen, discharge and material samples. Use them alongside the cleaning and screen-selection guide below.
Screen and outlet close-up
See the perforated screen, outlet streams and collected plant fragments. This shows where to inspect separated material during a trial.
Trial feed and sample inspection
Follow a mixed granular feed and examine the hand-held sample. Compare representative feed, product and reject samples when assessing your own seeds.
Small seed screening detail
Watch pale small seeds at the screen and discharge, followed by a sample close-up. The correct mesh opening still needs to be matched to your seed dimensions.
These are operating demonstrations, not measured before-and-after cleaning tests. Seed species, model and removal percentage are not identified in the clips. Loose fine soil can be screened only when its size allows it to pass the selected mesh; light impurities need suitable airflow. Similar-size dense particles and soil stuck to seeds may require a different process.
Check your material
Can it remove soil, dust and other particles?
Start with the difference between the seed and the impurity. Screening separates by size; air separation handles material that is more easily carried by airflow.
| Material mixed with the seeds | Separation route | What to confirm |
|---|---|---|
| Loose soil, sand and fine particles smaller than the seed | A suitable fine screen lets undersize particles pass while retaining the wanted seed. | The actual particle sizes must differ enough for the selected openings. |
| Stalk pieces, shells and other oversized particles | A coarse screen retains larger material while the wanted seed passes. | Oversized impurities can also be screened out; they do not have to be smaller than the seed. |
| Light dust, chaff and loose lightweight material | Air aspiration complements the screens on a blower-equipped configuration. | Airflow must suit the seed as well as the impurity. Confirm the blower configuration and check for seed loss. |
| Particles similar in size and air response to the seed | Screening and airflow may not provide the required separation. | Send a representative sample for assessment before selecting equipment. |
Please distinguish loose dirt mixed into a seed lot from dirt adhering to the seed surface. Do not assume a dry screening process will remove an adhering coating. A working video illustrates the process; it does not establish a removal percentage or guarantee the same result with another seed lot.
General process reference: FAO: grain cleaning. This explains separation principles, not a performance test of this machine.
One machine, different seed lots
Interchangeable screen plates: how many do you need?
One machine can be supplied with multiple interchangeable screen plates with different openings. Changing plates adapts the screening setup to another seed type. The number of seed varieties alone does not determine the number of plates: we also need seed dimensions, impurity sizes, the fitted screening decks and the required result. Do not assume that one seed type always needs exactly one plate.
Send a simple seed list before requesting a configuration
- Name every seed type you plan to clean, and identify each type in your photos.
- Include close-up photos of the uncleaned material, ideally beside a ruler, showing both seed and impurities.
- Describe loose soil, dust, stones, shells or other material to remove, and whether anything is stuck to the seed.
- Give the batch size or required hourly throughput and the cleaning result you need.
With this information, we can assess the screen opening sizes and plate quantity to include in the quotation. For small batches or home use, also state your available space and power supply; suitability and the smallest available configuration must be confirmed rather than inferred from a demonstration.
From sample to selection
How to assess a cleaning setup
- Identify the material. Match the seed lot, impurity types and desired separation to a proposed screen configuration.
- Confirm the configuration. Agree the screen plates, deck arrangement and whether air aspiration is included before ordering.
- Request a representative trial. Evaluate material flow across the screen and the separate seed and reject outlets using the proposed configuration.
- Compare the fractions. Check remaining impurities in the cleaned seed and wanted seeds in the reject material. Use the result to confirm or revise the setup.
This is a selection and trial checklist. Installation, screen changes and operating adjustments must follow the supplied machine instructions.
