Drying chicken manure

[Daniel]

We have the same problem.

The IBC idea is a non starter, the muck comes out on belts weekly about 17m2 a week, i don't fancy having to mess about with hundreds of IBCs.

@thesilentone, wouldn't a centrifuge need the poultry manure to be turned into slurry to get it into the centrifuge?

The liquid that was removed from the muck would also need to be stored and then spread with a slurry tanker I presume?

If its 17m3 thats only 14 IBC containers per week taking up floor space of 6mtr x 1 mtr.

That's only 896 ibc containers per flock, non runner .

Alligator bag?

So your talking 900 tonnes of chicken sh!t per flock. That must be a pretty big shed.

16000 birds

What about something like this based around hook load bins?

The problem is that every solution I can think of would cost serious money for little financial reward.

Number of birds does not mean a lot to me, On previous threads weight of muck has been quoted at 30-40 tonnes per 1000 m2 of shed. Thats 30-40 IBC's per 1000 m2.

Different type of sheds,

Belt dryer. Only way to dry that sort of sticky very wet stuff with low temperature heat (RHI hot water). Might still need a screw press up front to get it into a fit state. Lots of belt dryers doing AD digestate. I have seen them work on sewage sludge as well. Try these guys:

Excuse my ignorance here, but could you use something like this

Have you looked into a Fliegl dryer, certainly worth a look at. Very versatile, lower running costs than a belt dryer, available in stainless steel too if you feel the need at Boston 01205 357553 or at the Lamma show.

I'm wondering if blowing a load of chopped straw into the shed and mixing it in would be the best bet?

If you used a conveyor belt to run it into the shed and some kind of hopper to trickle chopped straw onto the conveyor at a suitable rate it would all mix in nicely?

I might park the combine in the shed doorway, engage the chopper, feed some straw bales in the front of it and then mix it all up with the telehandler to test the idea.

How wet is ur muck? Is your ventilation ok?

Ours is coming off at 27% dry matter or thereabouts.

Stacks about 1 metre deep, as you can see we've had a half-arsed go at mixing straw in, it would have to be chopped and added in huge quantities to have any effect.

So we've spent a bit of time and effort on this this week.

First we got the round baler out of the shed, we bought it second hand a few years back and it came with a chopper unit which we haven't used. I found the blades in the back of the workshop and got it working. Then we unrolled several round bales across a field and rebaled them with the chopper engaged.

Then I treked up to Fliegl in Boston who let me borrow their demo muckspreader. Then today we tipped varying amounts of chopped straw in the muckspreader and added about 7 ton of muck on top (It had weighcells). The reason for the Fliegl is that it is a push off type muckspreader, so the headboard and hydraulic rams push the load out rather than chain and slat on the floor. I think that chain and slat would pull the straw out of the bottom first before the muck on top, but haven't tried it.

We just ran it slowly so it didn't fling the muck far and it took 6.5 minutes to empty. If you didnt care how much it flung it you could do it quicker. We tried it with the rear hood down and up. With it down it mixed better, with it up it tended to drop most of the straw just off the beaters and fling the wet stuff further out.

Varying amounts of straw added, the pile on the left was one 4'6" round bale of chopped straw to about 7t of muck, probably a bit too much straw, the right hand pile was about 1/3 of a bale, theres probably a happy medium between the two but it got dark!

I would be worried about the straw locking up the nitrogen in the muck? Might be wrong...

Seems a lot of effort to me if I'm honest. I just tip ours straight in the fields!

Not sure about the N lockup

The idea would be to run the belts straight into the muckspreader twice a week. No more hassle than hooking a trailer on?

I'm sure your field heaps are covered?!
