in-line sap filters

[red maples]

I think this goes here.
I did a search but couldn't find exaclty what I was looking for.

1. Can I put an in-line filter(water canister house filter) between my gravity feed tank and my float pan to filter the sap?? and if so what micron filter would work best with out pressure.

2. if that doesn't work what else can I use in the same place.

3. I have 1 tank set-up... which the releaser dumps into. which is also my holding hank. ( I will change it around next year but its this way for this year)I guess the other thing I could do is set up a cloth type filter that the releaser dumps onto. if the castinster doesn't work.

any suggestions.

I use the 'pop on' sap filter hung over my head tank. It rated 50-100 micron and is quite easy to use. You have a round disc which supports a 10" or 20" filter bag. I have six of them and wash them in the washing machine (without soap)as time permits. This way I have a fresh filter every day -sometimes two. I would be worried about having a filter that could clog (cartridge) directly before the float. That's an accident waiting to happen.

I might end up doing that but I have a barrel turned sideways and I would have to cut a hole in the side but I might have to do that... was hopeing not too. we'll see what others have to say first.

Red gravity would not cut it for the inline filter. Just as soon as it starts to flow it will start to clog and be pretty much worthless. I would be worried as well about it not feeding the evaporator and getting in trouble real quick. I do the same with the pop on sap filters and it works good for me. You could also filter when you gather. Then put it in your head tank.

yeah I figured that would be the case. just wanted to check it out. I usually know the outcome just checking to what others have done. I do have a pop filter. So I'll just cut the hole should be easy!!!

thanks guys

I have a whole house filter in-line like you are talking about. It works fine feeding my 2x6. My feed tank sits about 5' above the flue pan. I do have a bypass valve incase the filter plugs (never had to use it). I don't remember the micron but it is a woven string style filter we use.

I wouldn't. It would just be one more thing to clog up or freeze up and could result in a burned sap pan. Filter the sap when it goes into your tank. Keep your tank covered up, boil the sap promptly and clean the tank when you detect odor or slimy sides.

They didnt work for me on gravity so I quit using them. I have one on my feed line from the bulk tank to the feed tank BUT im not sure I will use it this year because if you dont clean or replace the filter every day its a toxic waste dump that your running the somewhat clean sap thru. I used the cotton woven string and it allowed the most sap thru. DONT use the charcol type it will clog up quick.

I try to filter it when I pump it from the tractor tanks into the storage tanks that way it is clean from then until it goes into the evaporator. Everything you can filter out before it goes into the storage/holding tanks is less bacteria present and cleaner sap. Also, makes cleanup much easier.

A couple of things:

1. The carbon filters are probably technically illegal (they change the sap chemistry substantially).

2. Most filters made for home use have been washed, but not adequately rinsed (in my experience). I use the cotton woven string filters in my house. When I put a new one in, I run the water for about 10 minutes afterward. If you stand at the sink and watch the water run for a while, you'll notice that all of a sudden, when the first batch of water through the filter makes it through the pipes to the sink, the water gets very foamy (most likely soap or disinfectant residue). Takes about 5-10 minutes running full stream until the water runs clear again. Tastes funny during the time it is foamy as well. I wouldn't consider using this type of filter for sugaring. Most likely unless you're using them with a pump, they'd clog up very quickly as well, especially in the latter part of the season.

I use a 50 micron, wound string type, inline gravity feed and never had a problem. My feed tank sits 18" above the flue pan valve. However, after reading Dr.Tim's comments I think I will not use it anymore. I never tested it and had not noticed any foamy or different sap but I still believe Dr Tim has a valid point.

last year i had a whole house water filter in the line that i pump up to my feed tank, that way if it plugs i can change it while the evap is still running off whats in the upper tank. the thing i didnt like was i would use it just a hundred gal or so then not get a run for 2 days and have to throw out the filter cause it would get icky. this year i changed it to a fine strainer from mcmaster carr part number 9875k217 and was 16 bucks, has a clear bowl so you can see whats in it, and screens are available in many sizes i got the finest which is pretty fine. the screen i can wash and reuse it and replacements are only 2 dollars anyhow. that part number is for 3/4 pipe size but they have them from 1/2 up to 1 1/2 inch size, and no i am not affiliated with mcmaster carr! i just buy alot from them
