    In the 30 years that I’ve been producing maple syrup I have never experienced a season with such dirty (cloudy) syrup coming off the evaporator.  It goes through my primary filter from the evaporator but has a tough time going through the filter press.  I can only get half the volume through the press as compared to normal years.  Any one else experiencing such dirty syrup?

    Ours was very cloudy this year too, John! We will be filtering later this week.

    I have been fighting large amounts of sugar sand every year and I attribute it to the shallow soil with lime stone . A great combination for growing Cherries but makes for a lot of minerals in the finished syrup. My syrup looks like mud coming off the evaporator. I have a 24×24 flat filter on my finisher and I use a very course filter and it clogs withing 10 gallons. I’m giving up with that idea and went with 2 more filter plates on my press.

    I also have to clean my 3×10 every time I boil or I scorch my pans.

      I guess I shouldn’t complain!  This is not a normal issue here.  We always have nitre to deal with but usually not to the extent you have.  I can normally get about 20 gallons through my short stack 7″ press.  This year it’s a struggle to get 10 gallons through.  Happy sugarin’ !

    I used to have to clean my front pan every 300 gallons of sap. Two years ago my flue pan was even bad. This year I have gone through over 5000 gallons worth of sap and only cleaned 2 times and the first time was not even bad. I concentrate with an RO so less volume but should be same amount of niter. I do not know what is different but I do like it.

    I have never been able to get more than 7 gallons thru 4 window plates. Ever.

      Do you have a gear pump or a diaphragm pump?  Do you pre-charge your filter with D.E.?  Do you start out at low pressure?

      Diaphragm. Yes we start with low pressure. I’m guessing the precharge is whats missing?

      I have a gear pump so always pre-charge but still bypass the filter to start out at low pressure.  I know of others with diaphragm pumps that don’t pre-charge and have good success.  Still a mystery!
