    Default Anyone have a 9" CDL vacuum filter?

    After 8 gallons of syrup, I still haven't figured out how to use this contraption. I'm looking for someone who has used one of the new 9" models.

    -How much DE are you using?
    -Are you using the finish filter + 3 prefilters?
    -Do you run the shop vac the entire time syrup is in the top?
    2021: 28 taps. 18"x36" flat pan and dual natural gas burners.
    2020: 31 taps. 3 full size steam table pans on a custom 6x water heater natural gas burner setup.
    2019: 31 taps on silvers. Back porch gas cook top with 2 full size steam table pans. An amazing 14.9 gallons in my backyard!
    2018: 22 taps on 9 silvers. Propane turkey fryer and full size steam table pan on electric stove. I made 4.25 gallons in my backyard!

    I am not sure why you are starting another thread on the same subject. Have you actually read any of the advice I gave you in your other thread based upon my experience using the 12” version and actually used that advice? If you haven’t, then read it and try it, because the advice I gave you came from my trial and errors starting out with the vacuum filter last season. It should not make any difference in how you use it between the 9,12,18” size vacuum filter. I think your problem is that you are NOT using enough Maple DE in your syrup.

    Valid question. I have read it all, and tried many of the suggestions. I know you said more DE, and I put 1 cup into the last gallon and ended up with cloudy syrup and clogged filters. Other attempts with less DE have given me clogged filters and clear syrup.
    I have a small brain so I want to hear from people with the 9" who actually got theirs to work. That's so it eliminates the variables associated with the 12" version.

    I fully expect the end solution to be a result of user error. But the 9" model is new, and has less gadgets than the more expensive larger models. I just need some reassurance from someone with a 9" model that it does work.

    Jd,
    Seams like a reasonable request from someone not getting stellar results from his maple equipment investment. Since I am reading that the next larger (12 inch) unit works for approx. 60 gallons of syrup per year. I would assume the smaller one would be appropriate a for 15 gallon operation.
    Hopefully you will get some folks that use the smaller one to post some comments/ suggestions also to either one of your threads? Hang in there!
    If your making syrup have a back up plan for everything! Stuff happens. Continue striving for quality syrup.
    Keep boiling!

    How have you washed your filters between uses? Are you putting them back in same side up? When you clamp the ring down on the filters, do the latched snap over hard? Sounds like some how you are getting unfiltered syrup bypassing the filter.

    9 times out of 10 if my syrup is a little cloudy after filtering it is because of the reheating process to bottle, I have a double boiler but if I'm not careful and heat it too fast I get very fine sugar sand, or if the flame for some reason gets up the side of the bottler tank I get sugar sand. If you dont have a double boiler you need to heat it very very slow so as not to make it cloudy again after filtering. Also putting your final/felt filter in the same way every time is important.

    I've been doing the above suggestions but I'll be extra vigilant I continue to wash the filters correctly, clamp the lid on tightly, and reheat carefully (the 9" unit has about 3" of dead space underneath, so when its on my electric burner the syrup is being heated by air only). Thank you for those suggestions, I'm trying to keep the troubleshooting in the other thread.

    This thread is just looking for someone else with actual use of the 9" version. They were hard to find a month ago because they were selling out.

    My CDL 9” should arrive tomorrow. I expect to finish and bottle this weekend and can report back my findings.
    Happy to share my experience.

    I have not used my 9" vac filter yet but I noticed 2 things. One, the 3 clamps are adjustable. Do you have them adjusted to provide 100% force on the plate? Two, my metal plate is warped but flattens out when clamped down.

    Good we are getting some more testers! Awesome! Looking forward to the results. I like shiny new Maple things that work!
