    Default Homemade Filter press

    Evening all, I have been watching and seeing allot of videos on people making their own filter press with vacuum pumps, stainless steel pots, air pigs, flat filters ect ect ect, but I have yet been able to find anything or anyone that wants to share the entire process of making one.

    Anyone have any detailed instructions or a link to instructions? I am a DIY kinda guy but need instructions to follow so I know what to do and where.

    Thanks for any help or suggestions you may have.

I looked at the cheap stainless steel pots that most people seem to be using from Walmart and decided to spend a little bit of money and ordered a double boiler from Amazon that I was able to adapt to what I think will work just fine. I was also able to order weld list fittings to except 1/2" stainless steel fittings also on Amazon. I will also pick up a vacuum pump from Harbor freight to use for the filter press that I think will work great. I am still in the process of putting it together but given the YouTube videos and the information I was able to glean from CDL, I think I should be fine.

    I built 1 of these last yr. Worked good. But you would need the clamps like cdl has. I didn't have clamps an needed a second set of hands to hold down pressure to make the seal. I also started by using pre filters but still had sand. I then started using the orlon filter and 2 or 3 prefilters depending on the amount to filter. After that syrup was clear and free of sand. I have sense went to the small press like Maple Guys have but a different kind. That works better and can filter up to 14gals on a set of papers.

    I just built a similar prototype. SS pot for vacuum chamber, 5 gal bucket lid fits perfect over SS pot to get seal (a lot easier to drill than bottom of a SS pot!) & cut bottom out of 5 gal bucket as top chamber and a 12 cfm 2 stage vacuum pump W/ no reservoir tank. Worked pretty good. Latches will be an improvement over bungie cords. My concern is all the moisture mixing in with pump oil. I'm thinking of adding a 3rd chamber to cool steam back to water. By sucking stem through a couple inches of water? Any thoughts?
    2014 25 buckets, 55 gal collecting drum, cinder block arch, and 4 banquet pans = 4.75 gal
    2015 200 buckets, (3) 300 gal tanks, 9' home made arch, (2) 2'x4' flat pans @ 25 gph = 30 gal
    2016 stayed @ 200 buckets swapped flat for dropped n played with auf. 40 gph = 25 gal

    I used about 10 binder clips to seal the orlon to the pot. They press it down so theres about 1" of volume there too. I

    I say forget the vacuum pump and use a shop vet vac. Trickiest part of the whole ordeal is getting the vac right for me. I had too much vac sucking in the orlon with a 5hp shop vac. I closed the ball valve almost all the way and drilled holes in the hose to get it right. Super cheap and effective. Most people have these things in there house too. Just get the bulkhead fitting in the pot and attach the hose.
    2016 7 taps= 1-2 gallons of syrup
    2017 135 taps on bags/buckets =17 gallons syrup on block arch
    2018 75 taps on bags/buckets in new locations =50 gallons syrup (2 month season) on insulated barrel stove with auf and hobby r.o.
    2019 less taps on different ground for 1 month season. 20 gallons. Added 4x40 RO membrane and never finished 2x4 cooker.

    Very creative folks....just keep in mind to use food-grade materials for anything you use or make that contacts syrup.

    You need to be careful using a shopvac. If you don't allow some air to go through the vac you'll burn up the motor. Ask me how I know, lol. Anyway, the HF vacuum pumps are pretty inexpensive.

    Good advice. Cooling is necessary for most all pumps...just achieved in different ways, air, oil, water, etc. Put a bleed air valve in-line somewhere and use it to regulate the vacuum level and to allow some cooling air in.

    I used this to control my wet/dry vac that ran my aerator last season. It ran the whole season while making birch.
