There are way to many variables in this question. How many bales per hour can this machine dry? What are the variable costs such as fuel for the dryer?

To be honest I dont think you can pull moisture from 30 to 15 in 12 seconds without the bale catching fire...

 

For a short answer I would say yes that I could be interested in such machine.

In reality though I don't see it possible to be able to dry a bale in 12 seconds and it never get heated over 100 degrees. To me a somewhat more realistic approach to a hay drying machine would be something that would dry the hay before its baled. I'm thinking something like a machine that would have a pickup like baler but the hay would go through a heat chamber/oven before being deposited back onto the ground for the baler to then come by and bale it. An issue would be keeping the hay from catching fire since the heat would have to be very intense to dry the hay quickly enough to be efficient. Then the hay would probably to too crispy dry to bale(especially with alfalfa) so some form of steamer/humidifier would be needed after it goes through the drying chamber before it could be baled. I'm thinking that the dryer and steamer would be best as a single machine that would deposite the hay back on the ground ready for the baler and bale collecting system to come right behind it. With all the technology available I'm sure something similar to this could be invented but I'm not so sure at the end of the day how realistic and cost effective it would be for the average farmer/hay producer to own and operate.

 

Out west we have the opposite problem: Searching for dew

I will bale at elevated moisture intentionally with preservative to reduce leaf losses rather than beat all of them off.

I use a dry product from Pioneer called Alfalfa Innoculant applied through a Gandy box. It is touted as working to moisture as high as 25% and I have had it work higher than that. Specifically I wanted a product that held hay with stem moisture and this product works to around 20% in that case.

Most of my customers feed horses and I have used this on hay for over 20 years without a compliant.

One caution is that you need to have alfalfa stands that are free of grasses and weeds. If they are present at more than trace levels this product will not work.

Three44s

 

Hi everyone, thank you for your responses! Here are a few more points:

It may take longer than 12 seconds, but the machine would have several bales in at a time, so the average time per bale would be 12 seconds (i.e., 300 bales per hour), which we have found is about as fast as our baler can bale the small squares (I think they are 14x18x40).

Three44s: The machine would work equally well with stem moisture, dew moisture, or any other type of moisture. Even moisture trapped in the big weed stems.

Again, let's not argue whether it is possible or not, and just assume the machine exists and works (and you have seen demos). I just want to know if there would be a market. Based solely on the increased value of the hay, not to mention the reduced risk due to rainy weather, reduced stress in knowing that every bale is dry (even the ones under the tree line, no sorting required etc.), how much would you be willing to pay for such a machine?

 

I have been thinking of an idea to dry hay. If things ever slow down here want to do some experiments so see how will it will work.

 

Also, I forgot to mention (thanks PaMike) , let's assume the device requires 20-30 HP to operate at 300 bales per hour. So, however much fuel that corresponds to, but not much different (possibly less) than most pieces of equipment.

 

I've seen pics of a prototype machine that uses microwaves to dry the hay.IDK if its feasable or even workable.I think it was in Farm Show IIRC

found it.

 

Can't beat thermodynamics- the cost to run dryers be it microwave, dehumidifier, solar, heated air, forced air all add a serious cost to the bale of hay. The time to do such drying is also limited to certain rates.

Machine is neat idea but many have gone before you in this area and if you take a look around, the marketplace has not adopted them to a large extent.

Yeah, my idea is quite different from all of those. I've worked out the thermodynamics and everything seems feasible. I actually already have some backing on this project and am in the proof-of-concept stage. I can already make the case for why the technology can work, however, in order to get further backing, I need to show that there is truly a market for such a device (these investors are not farmers) and what the potential revenue stream may look like. For the obvious reasons, I'm not really willing to divulge any of the secret sauce as to how it might work at this point.

So, let's just go back to making assumptions that such a piece of equipment does exist and that it works. Would you be willing to spend your hard earned money to purchase one? How much would the machine be worth to you?

Thank you for taking the time to help.

There are so many variables, how many acres per day could your machine do? that has to be factored in, also the price must be just right as it will add to the cost of production and if above a certain level it becomes cheaper to import hay from other areas. Great idea though.

 

Short answer for me would be no. If it can't dry big squares, doesn't do me any good. Good luck with your venture though!

 

Trillium Farm: The machine could dry 300 bales per hour, so depending on how thick your hay is, you would have to calculate how many Acres/hour that would be.

stack em up: The first iterations of the machine will focus on small square bales, but the idea should apply equally to large square bales and round bales.

I guess it is too early to ask the yes or no question of "would you buy it." So how about we rephrase the question:

1. Would you be interested in purchasing such a machine?

2. How much would you expect such a machine to cost?

Thanks

 

Build it so it drys the windrow and uses the moisture to soften the leaves. Need to be able to pull a large square baler behind it. Look at the Stahelli Steamer as an example. As long as the operating cost is low enough I would be interested in buying one.

How much moisture is it capable of removing?

 

Just to add, continuous vacuum drying of hay has been tried as well since that's almost the last option. Hint, also energy intensive. ????

 

I don't know what your little bales weigh but if they are 50 lbs 300 bales per hr is not much hay. Needs to be at least 30 tons/hr. This will be an expensive machine so your market is going to be large growers with big equipment and lots of tons to bale. If I could reduce the drying time by 2 or 3 days, bale perfect leaf retention, and get the pivots back on sooner its worth quite a bit to me. I have to be convinced first though.

 

I would be willing to purchase this machine, however, price is a difficult thing to assess. Dependability, reliability, simplicity, and 'high moisture' max input would all be determining factors.

But, I would say, if I could guarantee that all my hay would be out of the field in 2-3

days via this machine, it would be worth $1/bale if it allowed me to sell that bale for $1 more given consistently better quality. So, $5-6K/yr with a minimum of 7yr essentially breakdown 'free or minimal' lifespan. I'd pay $20-30K with a 5yr bumper to bumper warranty.

 

What would the duty cycle/life expectancy of this machine be?

And do you have any information on maintenance cycles/costs?

 

Thank you guys for all of your input!

paoutdoorsman: At this point, sadly, I do not have any of that information on maintenance cycle/costs. All I can say is to assume that you can expect at least 200 hrs of operation (so about 60k bales) with no breakdowns and minimal maintenance. I understand that everything is being super optimistic but (I think) that is how most market research goes (it always seems to me like market projections are overly optimistic).

Like I said before, I would just like to get some assurance that if the product were available, there would be a market for it.

 

I'll trade my NH tedder for one of these things. For me mounting such a thing before a rake also would work. Oh I didn't read how it would work. No thanks not interested.

 

No. I wouldn't. I would rather use preservative. Or get aftermarket conditions rolls for the mower. Seems much easier.

A drying machine is invaluable if you know there's no other way to get hay dry. As long as there are cheaper ways (like the sun), that means that the cost of the machine will only be spread over the tons on which it's actually used instead over one's entire crop.

 

If your machine could taker a large windrow and dry 30% moisture to 14% moisture, you might have a winner. There are to many variables when it comes to bale size, density, and qaulity. But if out could dry a windrow at raking speed, you would have a huge market. I would be afraid to run 30% moisture hay thru my sqaure baler. Also a lot of the northeast US, which is where a lot of sqaure bales are made, use kicker wagons. Dropping bales on the ground isn't a option, fields to damp/steep. I would be afraid to take a stacker wagon on some of my fields.
If it could take freshly cut hay from full mosture to 60% in a pass, you would have all the dairy guys buying for chopping and round bale and wrapping.

Drying already made bales, i don't think it would work for me, but a machine that could dry a windrow, at 7 mph, I'd be all in. Priced in the 20 to 30 grand range. If it truly meant turning 3 day drying to 2 day drying.

You won't be able to charge more. It's a question of good hay vs bad hay, if you charge more they'll go elsewhere.

 

I guess it is not a case of "If you built it they will buy! "

 

Oh I finally recalled the last drying option I know of, I'm not aware of any working ultrasonic driers that have ever been built for hay. I know there are some for fabric drying but not even sure the concept works for water bound into plant structure.

 

Yeah it seems like the big issue is the variability in the types of bales people are making. I do think that the hay would be of a higher quality because it could be baled at higher moisture with more leaves intact. So if you raised the quality of hay from Excellent to Supreme, you would see a decent return on investment because of the higher prices that Supreme hay commands.

The biggest competitor would certainly be preservatives, which provide many of the same advantages with a significantly lower upfront cost, but there are recurring costs with that. I also think that just drying the hay would be better than using preservatives. If I recall correctly, I think preservatives (at least proprionic acid) only hold it off for a few months - and by that time your hay needs to be dry, or else it will mold. Although usually the hay is dry by this time, but it's not good to place it in large stacks for this reason.
