It depends on the DM% of the solid fraction.

I bed with chopped straw I guess I take 1/3 out. It's a fair heap at the end of winter.

Didn’t really ask depends on what the sh1!s like I suppose,might try it when the lagoons full,24hours in a day like
£300 a day or £1500 for a week,4screens in it feeds it self
How much to purchase?

Man wanted C£28K earlier this year for a small Separator ( up to about 150 cows I think ) tractor mounted pump/mixer plus pipes and wiring. So £60K ( provided the output is high enough) could be attractive if you fancied the option of some extra work?

The Bauer Plug and Play units start at around £44,000 for a unit that will work for up to around 350 - 400 cows. We do a smaller stand alone unit which will do for up to 150 cows which is around £9000 but you have then to factor in a feed pump, mixer etc.

Thinking of buying one of these mobile separators. I have been doing some calculations. It's roughly 100mins per standard beefhouse link. That's 15x10x8 tank per link. So three link tank 300mins at 20m3 per hour. How much can I charge?
The machine is 53k plus a generator and trailer to set it on plus a stacker belt.. So 60k really. Is there a demand for this?
Not sure yet. I suppose it depends on how much it costs . The law could change regarding green bedding and using a mobile plant with regard to desease control..
What are your thoughts, all input is OK. I don't expect to get rich doing this but a bit of money for food would be good

Think you can call it closer to 70k by the time your set up properly then you need something to pull it. Tb would be a major concern
How do you test a separator for tb? Measure a grease nipple?

Hes correct of course. And a collection of other bodyfluid carried deseases. Especially out of a biodigester. You are trying to create an environment where bacteria thrive and moving a plant around that will be contaminated with everything. Then you use the dry materials to bed your cattle. Botulism is a major concern if some of your customers are using poultry litter. In the event of foot and mouth you would deffo be parked up.How do you test a separator for tb? Measure a grease nipple?
Buying this is not without risk . I'm busy talking myself out of it..

In reality, would you also at least want to offer the service of spreading the liquid fraction at the same time?
Otherwise , you are restricting your customer base to those with both a sufficiently large slurry amount to make it worth your while, plus either another pit, or the machinery to cope with 15m cube per hour ( from your example )

A pump of red grease and a pump of blue grease and your only in the sh!t if the guy in the shop who sold you them both moves the goal posts

Yes a lagoon or another tank for the liquid is required. You are really just taking the solids out of the slurry to enable the grass to access more of the nitrogen.
Thick grassy slurry is rich in nitrogen the problem is that alot of the nitrogen is lost in the process of breaking down the grass.
Eg when we put bark on our flowerbeds and rockerys why do we do it. It is used to surpress weeds and grass. Why does it work? Because the nitrogen is being used by the bacteria in the bark to break it down. Only weeds that require very low levels of nitrogen will grow. However as the bark is broken down it will eventually lead to actual growth. The same happens when we spread thick slurry we lose nitrogen.
When we Plough It down we smother it in the bacteria and this helps break it down quicker..
Like when you get compost from a recycling place.. If it is fresh it will grow nothing for about two years until it stops breaking down.

I think you'll find that green bedding works best when made fresh each day. Otherwise you'll have to take it all the way to compost.
It can start to heat quite rapidly

I have been told that this material can go back into a digester with a small amount of fresh silage added. I'm not sure if this is correct but I will try to find out more. If this is true it puts a completely different slant on the whole economics of separation. Being able to reuse the solids in this way would represent a huge saving on silage.

We nearly went for green bedding few years ago but dicided not too in the end as Sand was so cheap. Sand getting more expensive and eating so many things. Our cow slurry is properly thin on organic clover Multicut. Is there enough in this to separate or has cow digested what little fibre there was.
By the way I’m not sure mobile separating is a good idea due to bacteria etc and the AD plants have almost certainly got their own if that’s what they want to do. Thanks
