Put in sample and start the cleaning process. If necessary, the sample is first deawned for a preselectable time. Then the deawner opens automatically and the sample falls through the aspiration chamber. The lightweight dirt such as dust is extracted by the aspiration and deposited in the dust bag by the cyclone. The sample runs over the straw sieve, which removes bigger impurities, and then runs over the sand sieve. Sand and small impurities such as weed seeds fall through the sand sieve. The impurities, sand and weed seeds run into the left-hand collection pan, and the quality grain runs into the right-hand collection pan. A feed funnel is available as an accessory. This means that the sample cleaner can be used for large sample quantities such as for seed cleaning for trial plots.
