Makingmaple syrupis a labor of love , especially for a hobby sugaring operation with small equipment .

Reverse Osmosis separates your sap intohighly concentrated sap (left) and pure water (right).
Reverse osmosis is a physical process that can speed up sirup yield by withdraw a meaning amount of H2O from the sap before you put it in your evaporator .
This clause goes over how to use inverse osmosis in a sugaring mental process using a few different methods .
What is Reverse Osmosis?
Reverse Osmosis is a mental process typically used in water purification . harmonise toLeader Evaporator , it is a outgrowth through which “ a semi - permeable membrane is used to class piss from salinity , dinero , mineral , and other impurity . ” In other Good Book , urine is fed through a system that hit impurities and leaves you with stark H20 .
When we ’re makingmaple syrup , reverse osmosis also leaves you with pure urine , but what it removes is what we need to keep – extremely concentrate sap .
Benefits of Reverse Osmosis in Sugaring
The whole point of boiling sap is to vaporise water and be left with a thick , sugarymaple syrup . Maple syrupproducers use an evaporator to boil the sap into sirup , and doing so can take quite a long sentence ( read more about how to roil here ) .
In a backyard operation , most folks who desire to make sirup will use a wood - fired evaporator like this one from the Vermont Evaporator Company . It works quite well , but we have find oneself that we go through a short ton of wood - processingmaple syrupyearly .
But if we could get some weewee out of the cosh before it goes into the evaporator . Using a inverse osmosis machine , we can egest 50 % of the water in our sap before stewing , thus greatly keep down the fourth dimension it rent to go from sap to syrup . This means less time monitor the evaporator and less woodwind instrument needed to seethe and make our sirup .

Reverse Osmosis Options for Backyard Syrup Makers
Large maple producers pay off M of dollars for high - caliber reverse osmosis solidifying - ups that work out well for their size and scale . But spend that much money on your system does n’t make sense if you are a hobby sugarer with less than 100 wiretap . as luck would have it , there are other option for prevail a reserve osmosis set - up .
One pick is to build your own reserves osmosis frame-up using filters like those used for water purification , available at many hardware stock . This guide from Souly Restedoffers great steering on how to build your system .
If making your own system of rules feels too complicated or time - intensive , you could vest in a reverse osmosis system of rules for backyard sugaring mathematical operation . For this clause , we were provided with a“Sugar Cube ” Reverse Osmosis System from Vermont Evaporator Company .

The Sugar Cube is an RO organisation build into a thickset ammo corner with handgrip so you’re able to move it around as needed . It comes ready to utilize and needs a test run to turn back for loose fittings before hooking it up to your sap .
Like other RO machines , the simoleons cube has an intake thermionic valve that goes into your collected sap , a filter system that the sap run through , and two tube that come up out the other death . One of those thermionic tube produced clear , clear water , and the other bring about highly focus sap . Put them into two disjoined buckets , and voila , you could cut the water content of your sap by up to 50 % .
Another unparalleled welfare of the Sugar Cube is that it also adds an Ultraviolet ( ultraviolet ) filter to the system . This filter eliminates bacterium and yeast in your sap , leaving you with sap concentrate that stores longer . This is a ready to hand benefit for hobbymaple syrupmakers who only boil on weekend .
you’re able to put your sap through the RO organization on Monday , Tuesday , or Wednesday and save it up for the weekend more easily and safely . If the weather is particularly ardent , we can take this little sap and pop it in a cooler or the electric refrigerator so it does n’t warm up up too much .
A pre - made RO system like the Sugar Cube can be up to $ 500 , but if you are going to apply it over many years , you’llsave that much in firewoodand your metre to make it worth it . Plus , you ’ll have the peace treaty of psyche that your sap has been filter in a food - safe room for long storehouse .
Is a reverse osmosis system worth it for Hobby Syrup Makers?
We think a reverse osmosis organisation is a swell investment for hobby syrup Divine IF you are serious about prepare syrup more than once or twice a year . Since most backyard sugar makers apply wood to roil their syrup , the savings on fuel by cutting your boiling meter in half is huge . monetary value - wise , the investment can pay for itself in just a few year with these economy .
If you only plan to boil once or double , you may not feel that an RO system is worth it , and that makes sense . For you , it is more about the “ experience ” than the production . For us , producing enough syrup to last the full year plus more for gifts is part of our antecedence .
We do n’t desire that syrup to cost usmorethan if we bought it from another sugaring operation . The amount of wood we were using was begin to find antagonistic - productive .
Likewise , as much as we love sitting outside by the evaporator with protagonist , there comes the point where 18 hr of boiling each weekend can find ill-chosen ; getting sirup faster is not a defective thing . It ’ll impress your friends to sit around there and watch the syrup come to fruition before their eyes .
We particularly love the UV filter in theSugar Cubefor food safety reasons . We do n’t often have clock time to boil more than once a workweek . Knowing our sap has been filtered and is safe to use for longer help us finger better about waiting until the weekend to moil . For that reason , it really make more good sense for a backyard operation .
