Evaporation rate per square foot

[Jec]

Does anyone know the evaporation rate per square foot?
Thanks in advance,
Joey

theres a fella on here that said he got 12gph with his,i dont know what mine gets, never checked,but i suspect around 15,its been converted to oil.

[Jec]

Oh I heard it can get 17 gph and Im adding AUF so im guessing 18-20 but I want to know for sure.

[flooder]

d&g told me 25 stock but they were way off

[Jec]

Yeah no way I want to get 20 if I do AUF and preheater but thats a stretch. I don't kow where they came up with that number.

[flooder]

sales pitch.I'm gonna keep track of mine this year and see exactly what Iget with oil

[Jec]

Yeah I'll try to do the same. I am really curious about the GPH.

I almost spit oatmeal out onto the table when I saw this, Sapzilla! Funny!

Ok, I'm the this to admit I'm dumb! Whats this thread about? Is it a manufacturuer who is coming out with a 20" X 30" that is supposed to do 25-30 GPH? Honestly I'm getting in this year after selling sap and looking for an evaporator for about 150 taps. Help!!!

No it was supposed to be about if there was an evaporation rate per square foot. Meaning an average GPH per square foot. Like a rule of thumb. I wanted to know if there was such thing.

Just my personal thought to your question. If you have a 150 taps on the very best day you would probebly get 150 gals. of sap. A good friend of mine has a Leader 2by4 and he averages 15 gls. per hour or gph. Therefore you would be looking at ten hours boiling time to handle 150 gals. I would suggest a 2by6 with 2 foot syrup pan and 4 foot flue pan. You would probebly be around 30 gph with that setup and would not have such long boils. You would also have room for expansion in the future if you would go that route.Always go a little bigger than you think and you will be just about right.

im pretty sure I have heard people on this site talk about different evap rates per sq ft depending on flat or flue.

As for Joey's original question, about the average GPH per square foot . . . . . I think the common expectation for a flat pan, based on what I've seen on this site, is 1 1/2 gallons per hour per square foot.

Now with a flue pan, there is more "actual" square footage of surface area for every "apparent" square foot of pan. I suppose each 6" flue adds 1 1/2 gallons per hour.

Now to complicate the calculations, I don't think that most flues are 6", and the number of flues per "apparent" square footage of pan varies.

Who is the math wizard on this site?

Thanks for your suggestion. Currently looking for a good used 2X6.
