Who boils with their syrup pan covered by a hood?

[heus]

After years of fighting to contain steam from the syrup pan of 3 different evaporators I made the decision to have my syrup pan hood, which now cantilevers off the flue pan hood, modified to sit right on my syrup pan. I am having a large door made on either side for easy access. I know of one sugarmaker in my area that boils this way with no problems. Anyone else boil the same? Its a 2x8 Smoky Lake with an auto draw.

I have a hood over the syrup pan, but it is about 14" above the pan. It still collects most but not all of the steam. It may help that on a 3x3 pan and hood, it has a 15" stack.

I have boiled both ways, when people visit we raise the hood so they can see in. When we are alone or it get hot in the shack we lower the hood. No problems running either way. Our hood have stacks that go up thru roof so either raised or lowered we get very little steam in the shack. When raised does put more heat into the room.

my hood covers my syrup pan,but is suspended ten inches or so above it,i made curtains from heavy vinyl like the drive through forklift door material that hangs down over the side of the pan,so seeing in is no trouble,but all steam is collected and sent up and out.

This may be a question more than a suggestion? But. Exhaust hoods in industrial applications for energy conservation limit the exhaust for a hood so that it "JUST" removes the vapors they need exhausted. IF there is vapor (or steam?) venting past the hood then you need more positive exhaust flow. Could a little help like a vent fan keep steam from venting past the hood and solve the problem? then you would still have clear view of the pan but no steam in the shack. Or am I missing something? thanks Jay

I want to get a tight fitting hood for my syrup pan and or Pans, I have seen many oil fired leader Rigs with tight fitting hoods on the syrup pans, even with a door open that is essentially the full length of the pans they take 95% plus of the steam up the stack. They are impressive. And it's a nice clean look.

Jason,
I heard you had a big day with some local visitors.
I boil with the front hood down almost on the front pan, but it has a 4-6 inch gap on both sides and the front. 95% of the steam goes out. and I can still have instant access to the pan compartments. Your welcome to come over and look at my set up. We can discuss some options and why this works. Not sure how it might work on smaller evaporator? Mine is 3 feet wide 4 compartments.
Regards,
Chris

Chris yes I did
I have seen your hood in pics and I would probably have gone that route but I'm just having David Yochim modify my existing hood.

Our hood sits roughly 18 inches over 5x6 front pan. 15 inch stack with an exhaust fan in the stack. All the steam goes out the stack unless doors are open sugarhouse and its windy out. I personally want to see what's going on in each partition all the time, but especially on start up.

I do know of a good in our area that does sit tight on the front pan, but it was made smaller than the front pan on purpose. What they did was make the hood 1 partition narrower than the pan. This way they would leave the partition they were making syrup in exposed for easy viewing. The exhaust stack had a section of flexible stack on the lower end so that when they switched sides they just slid the hood over to the opposite side. Neat idea, but I still prefer to see everything.

I'm running a 4x16 Leader Vortex and boil with the hood resting on the syrup pan it works great, any condensation that does build up in the hood flows out and in to a drain to minimize water on the floor. When we have visitors I raise the hood so people can see it boil. I can raise it about a foot before steam starts to roll around the edges of the hood.
