Don't worry. I gaffer taped a 3 foot length of solid pipe on the top and hoovered it right to the floor. So tis done.Brilliant!
But I think you should cover the top 3 feet or so perforations with tape or something to make it flow from lower down to get a better area coverage!
I'm amazed it dropped in so easily.I know someone has said they use it in the past, and also that they used a hoover to put it in after filling the store.
I thought I'd give it a go today. I had some twinwall here, so zero cost.
See how it goes, won't get much cheaper that's for sure.
So was I. I was leaning on it full weight but it's a hell of a lot easier than screwing hot spot spears in, I've the blisters to prove it.I'm amazed it dropped in so easily.
Very neat.
You putting a fan on top to get air flow?
It's a gerni, spaldings supplied it, got the same output as a big brute motors, but a fraction of the cost, and I'm going to set up an intermediate collection bin. So will have the same size receptacle as the big brute too.Thats an impressive hover. Not sure my Henry would be up to that.
Is that 4" pipe?
I have 250 tonnes I'm going to use it on. Don't forget the bottom on the pipe is open and drawing from the very bottom of the heap so there's no restrictions on air flow at all.Great idea but I'm not sure how well it will ventilate ?
When polycool first started selling pedestals they didn't work well with as they had a 300mm bse and that didn't allow enough airflow to be effective at any decent radius - they moved to a 450mm base as a result that gave them more airflow than metal pedestals and they ten worked very well
So a length of 150 or 200mmm twin wall wouldn't have a lot of airflow at all, thats fine if you sticking them in every few feet but not if you are trying to ventilate a decent area IMO
I wonder if its possible oi inserts a pedestal into a heap using this method though ? certainly would be better tyo do it after a store is full rather than during loading

Plus I've just costed it out at £6 each so they can.go close if need be. I've a sinar temp/moisture spear to keep an eye on things with.
To put pedestals in I think you'd need a sucker blower for it to work, 450 mm is massive.
The top metre is solid.The other problem you will have is that air will always take the route of least resistance so the holes towards the top will flow more than those lower down and air will be pulled through the top of the heap and not the bottom
This is why only the base of a pedestal is perforated and the exhaust pipes are solid
Although it's a cheap solution I really have my doubts that it will be at all effective
The top metre is solid.
I agree on the fan moving but that's not such a hardship 30 secs per fan really.that will certainly help as will placing them close together (but that will loose you storage space and mean lots of fan moves)
It's certainly a cheap solution but really do have doubts as to how much of the pile you will actually get air flowing through
I agree on the fan moving but that's not such a hardship 30 secs per fan really.
Losing space though I'd be surprised. The 450 mm pedestals will displace an awful lot of grain wouldn't they?
I'm sure someone better at maths thsn me could work it out.
Apart from monitoring temperature, how can flow be checked?
Just done a few calcs while moleploughing.If you want to use cheap twinwall I would do it this way
you could use a pitot gauge to measure flow but the real test will be how well and even you are able to cool crops
If I was going to use twinwall I would lie it on the floor as laterals - that way you would get even airflow through the heap top to bottom
