Is 37 degrees enough to run dry grain down a 30' long chute?

[MattR]

As per title, thanks!

Just about I would have thought.
I’d be happier above 40 degrees though,
Grain gets up a good turn of speed & stops any lodging.
Are you loading a trailer/lorry from an elevator?
Somewhere on the web there will be a graph or chart or something with the exact details of what you require.

Thanks for your reply @Gormers , trying to plan how our new (to us) mobile dryer could fit into the existing (pretty antiquated) set-up. The chute would be from the output auger chute of the dryer down into a pit that would in turn fill the bins/store if that makes sense

 

[Gormers]

Yes makes sense
I think you will be ok with wheat.
Barley will need keeping an eye on because of dust and awns slowing things down.

Helps if it’s well polished before you start.

Oats may need a steeper angle,they will not flow as easily.

Who's the chap selling second hand grain gear, based on Bedfordshire? He's a regular poster in here but I've forgotten his username.

37 degrees sounds pretty shallow, but dry grain will flow better. If you can't do angle then a bigger diameter/width would help slower flows a bit.

Are you thinking of @grainboy ?

I am indeed. Thank you.

Be aware!, I have a similar set up and condensation can build up while drying and run down the tube, which can then cause a clog up until it clears, though a good straight steep slope gets it up to speed and should then clear the moisture.

 

[grainboy]

By the rule book 45 degrees for normal, 60 degrees for dirty products, but you may get away if the incoming flo is good, and no restrictions at the outlet, also as above, product would have to be clean,

 

[grainboy]

Have available second hand conveyors

which would guarantee flow,

I'd not like to guarantee that it would flow at that angle. If its fresh from the drier, the kernels can be a bit sticky and reluctant to flow. If its your own set up you might be able to experiment, as an ex grain equipment supplier/installer, I would like to see it at least 40 degrees.

Yes but keep the inlet opening hole less than the size of the pipe so control the flow. We cocked up years ago and just assumed the same hole would be fine but even dry grain can bridge so we ended up welding a plate onto the end of the chute to reduce the inlet size by about 20%.

 

[Brisel]

@MattR can you adjust the discharge from the drier? You may need to slow the flow down if it can't get away. I'd prioritise the speed at which I fill & empty the drier to make the most of the time consuming bit i.e. drying. Even if the angle wasn't right to fill a pit up I'd be happy with getting 60% in and having to bucket/shovel the rest while the drier is refilling.

Thanks for all the replies. Given that most seem to think its borderline, I'm rethinking it a bit and looking at whether the dryer would go better alongside one of the bins and then use the auger from that one to fill the other bins/stores - will need an hour or two with a digger sometime and maybe a bit of hardcorde/concrete to make a level ish site for it but I think it might be a better option with plenty of angle to chute the grain right in, also will hold more than the pit

You might like to consider using the pit area to dump wet grain to dry.. eg make your drier intake pull from the existing pit, or even using your existing elevators with a diverter to fill the dryer

A side entrance to the bin would be a good way of emptying the drier out quickly & useable for other grains later on if you can reseal the hole.

Would the existing elevators be able to fill the drier quickly enough? If not, a big hopper over the drier intake auger would give you a buffer store.

Like the dump bin, homemade with Crital panels ?
