Hard for me to beleive that the fall semester is almost over. Decide to make the hour and a half drive home from school to hunt tonight. Saw a few deer, only one buck which was a little four point...owell it was a good night to hunt very calm in the woods. So far I have around 4 cords split a stacked and im starting to get the itch, cant wait for tapping time to get here and to try out the new evap.

I bought a stainless steel countertop 7' long with a 16" sink in it for $30.00
yesterday. It even has a backsplash on the ends. I was going to get an 8' piece of formica countertop, but this will be a better way to go.

Parker, with the new RO what flow rates are you going to get and what levels are you going to concentrate to? Also, now that you have the RO, how much wood are you going to put up? Did you say there's 7 membranes...4" or 8"?

The machine has 7-4" vessels with 2 membranes a peice,,,was told not to try to run more than 8 new 4" membranes by someone that had the same model in the past..I guess the way the pump-feed lines are set up it wont matter how many you have after 8 membranes,,,all new to me,,,,,,I really dont know what to expect,,Think it will one pass the sap at around 800 gal. an hour? and I think I will just not pinch the pressure and recirc. back into my holding tanks while we gather-check for leaks,,try to make enough concentrate so we will be able to boil for 3 hours....if we dont have much sap Ill run it with the evaporator? or just run raw sap? (been told I wont do that after I boil concentrate) I am still gonna finish filling the woodshed just in case there is some unforseen problem...looking at my boiling records I can see that having enough sap could be a problem,,,,so I am going to add as many as I can befor the season..........
Got the walls up and the roof screwed down today,(kinda unique roof),still a ways to go but my goal is to have the room tight and heat on by friday...time will tell!

Parker- If you recirculate while your gathering that will work real good for you probly. When you do that you just run it open flow with the concentrate and the machine wont be so prone to clogging. Just dump water. My seprotech that I ran last year right out of the hole with two new nf270s did 10 gallons per minute of water running that way. My machine would be considered a 900 gallon per hour deal with the extra vessel and just the 5 horse high pressure pump. Thats twice the pace of mighty marvin right there. Maybe that unit of yours would be just as good. Theron

TTTHHH(closeinginonqubecfast)RROONN- was that with 4" or 8" membranes,,and how long are your membranes?

[maplwrks]

Parker---I think the theory behind using only 8 membranes is this---Many folks feel that if you add more membranes you acheive more out put. This is not true. You could put more membranes in your rig, but it will only put out what the pressure pump has capacity for. An expanded 600 gph machine will not put out 1200 gph, it will only put out 870 gph which is what the pump is rated for. The more membranes you put on the machine however, the lower pressures you will see. I think that the person that told you that, probably didn't feel it was worth putting more membrane to the machine without a significant return for his investment.

I got my stubbies and check valves yesterday. Last night my wife and I made up the drops. Today we're going to install the drops. The next day or so I'm going to test out a high vacuum pump with my homemade releaser.

I've been off all week to archery hunt. It has been terrible. The season started great with a lot of deer sightings. this past week I'm lucky to see a deer a day. The past three mornings were in the mid 20's while hunting. Pretty cold while sitting in the tree stand.

Hmm,,,I am pretty sure I can get membranes for $175 each.(1400 for 8)..But then agine with the limited ammount of sap I am going to get,,,,,mabey 4000 gal. on a good day,,,how fast do I really need to concentrate when marvin is going to still be doing 250-300 gph?
Now,,if I am just running the sap thru the machine and not building the pressure(recirculating back into my holding tanks) will I be doubleing the concentration (going from 1.5% to 3) of the sap? And say I am doing like 700? gallons an hour,,I will turn 4000 gallons os sap into what % of how many gallons in 6 hours?
If I have mountian dew looking sap how much can I run thru the machine befor I have to do a wash-rinse?
Thanks...trying to get some basic understanding....

I can tell you that last year using a 6x14 with 4900 taps, concentrating to 8.5% I boiled every 36 hours. I would only have to boil for about 3 hours each time. I also have a steamaway which increased my sap to roughly 11.5% entering the flue pan. So if you concentrate to 12% to start with the amount of taps you have you wont be boiling long. And no you wont boil raw sap after you use the osmosis. It just wont happen.
