That's awesome! Vacuum is my goal for next year. My hill is so steep I haven't walked it enough and critters have cut my volume...not next year. I processed another 60 gallons tonight that I ran down and grabbed this afternoon - like yours a bit cloudy. Can't make it tomorrow, and it will be so warm it will spoil so I pulled my lines and rinsed out my tanks but left taps in. Killed me to pull them when running so hard, but I'm guessing that will change quickly with temps hitting 70. Still hoping for one more run, but not holding my breath.
Thanks for the offer...I may take you up on that. Getting to 13% vs 7 would be nice. I have 4 150 gph standard size membranes and an aquatic pump and a feeder pump..I run it at 130 psi and get out about 10 gallons of water per hour and around 3 gallons of concentrate. I have extra membranes, so may look into adding them into the mix but I don't know if my pump will keep up the pressure to give me any gain. Do you use a protec pump?
2014 - 8 taps, turkey fryer, 130 gallons sap, just under 2.5 gallons syrup.
2015 - 50 taps and counting.
2016 - 60 taps on 3/16 and a Bill Mason evaporator on order.
2017 - 115 taps on 3/16, homemade r/o.
2018 - 150 taps on 3/16, r/o a big help, but lots of leaks killing yield.
2019 - sticking with 150 taps or maybe less, focusing on good vacuum and less waste to increase yield. Doubling up my r/o, and made a vacuum filter that looks promising.
