Removing oilseed from milling oats ?

    I've had a load of milling oats rejected due to them finding low levels of OSR in the sample ( 6 + seeds/100g). Long story short, I need to find a way to either remove it or take a £20 hit on 150 tonnes (£3k).

    We have a Bryce Baker 'Trip-bat' rotating drum cleaner with a 3mm slot and 4mm hole screens but oats pass through both. A 2mm hole screen would probably plug with oats (and need brushes fitted) and be slow as sin, a 2mm slot would allow 'light' oats to pass through, and we're already short on the contract tonnage. Bushell weight is well within contract spec.

    Would OSR pass through a 1.5mm screen?

    Where's the best place to find sheets of punched hole screen (218cm x 117cm)?

    There isn't any way to integrate a mobile seed dresser with gravity separator into the handling system (would be £10/t) so thats ruled out.

    Any ideas?

    Rig a small hopper to go on front of combine and put it through there

    I made auger cleaner with 1/8 hole punched sheet that works a treat for what you want to do might be worth speaking to astwell augers

    We used to have a short auger with a small round hole screen which only used to take dust and small weed seeds out, had a small hopper, if you could find one like that it would be a very cheap way to do it. It used to feed a President pre-cleaner over the intake pit (many years ago now!)

    Interesting idea. We could feed the combine from an overhead conveyor in the grain store, but I would be concerned about the dense 'stoor' (dust) from the combine causing a dust explosion.
    I bet they'd still reject it, for 'skinned grains' or 'mechanical damage' or some such.

    I used to grow milling oats years ago.far better break than osr,BUT, they bought them no bother IF they needed them,if they didn`t,they would find any excuse under the sun to not buy them, or dock the price.

    Combine would be better outside seen people doing malting barley and putting osr through to clean it where it’s heated
    Open concave fully it’s just like a big dresser

    Is that a local mill?
     
  12. Probably not.

    Sounds like you need a flat screen with 2mm holes. An aspirator or gravity table wont be much help.

    Is that level of osr in the sample outside the spec on the contract?

    RE-SO at Stafford , now part of Agri, had a bulk cleaner on a lorry and would travel.

    OP ruled mobile seed dresser out at the start.
     
  18. 6 seeds weigh 0.03g, which should be well within the contract spec for admix, which is usually 2%,

    2g in every 100g would be 400 seeds, which admittedly looks like a lot more than 2% in a sample.

    I did wonder why there was no reply from PSQ on this. There are some contracts that specify no black seeds apparently. How remarkable is it that we can provide natural products that are out of spec when the problem is 0.01grammes in a 100grammes!!
