Maple High Brix yields sweet success for sugarers

by John Ho, Efficiency Vermont Energy Consultant

John Ho, Energy Consultant, meets with Glenn Goodrich of Goodrich’s Maple Farm to review his new High Brix setup. The system will pay for itself in four years, and then provide the farm substantial savings on fuel each year.

Sixteen years ago I graduated from University of Vermont with an engineering degree, and while I had shallow roots in Vermont I was not firm on staying. After I got married, my in-laws made us an offer we couldn’t refuse: a four-acre chunk of farmland, up in Franklin County which established my roots in this rich Vermont soil. We built our house on this land where we're now raising a new generation of Vermonters. There's a little sugar bush on a corner of the property, and a few years back I built a small rig for boiling. I boil on and off each year, just for fun.

I found work with Efficiency Vermont as an energy consultant, where I use my engineering skills to help businesses save energy. Efficiency Vermont has always offered energy-saving programs and rebates to farms, but in recent years we've expanded our agricultural reach to include sugar operations. As it turns out, my personal interest in sugaring has had a real influence on my work.

Sugaring is part of the fabric of Vermont, but reducing 40 gallons of sap down into one gallon of syrup takes an enormous amount of fuel and time, and that’s a risk to Vermont’s sugaring future. For the big producers fuel costs can make it harder for them to keep up supply, pay competitive wages, and compete with producers in Canada and elsewhere. For the smaller operations, particularly those that use wood they may harvest on their own property, it really boils down to time—a scarce resource these days.

Collaborating with others at Efficiency Vermont we were able to introduce programs to help sugar makers keep down costs and time spent boiling, including specialized vacuum pumps, variable frequency drives, and, most notably, reverse osmosis (RO) systems.

Reverse Osmosis cuts sugaring time in half

RO systems use a membrane to help reduce the water content in sap prior to boiling it, which can cut processing time by a whopping 50-75%. While a lot of the larger operations had already discovered RO and invested in it, the technology was more out of reach for the smaller guys. We wanted to change that, to keep small-scale and backyard sugaring operations more doable for everyday Vermonters. I’m proud to say that initiative was a success, with 121 sugarers taking advantage of our RO rebates and technical guidance.

Since then, we've rolled out some additional equipment rebates and I've worked with almost 100 sugar operations evaluating their processes and helping them find cost savings.

High Brix keeps production competitive

Recently, we've been testing out a new advancement in osmosis tech, named High Brix after the high sugar content it yields. To better understand the efficiency potential of High Brix equipment, we've been working with Goodrich's Maple Farm and the Proctor Maple Research Center at the University of Vermont. Both have installed the equipment and are testing it out, while we measure and verify energy savings.

It takes 4.1 gallons of no. 2 fuel oil to make one gallon of maple syrup. New High Brix advancements will bring that figure down to .19 gallons of fuel.

Goodrich Maple Farm has been operated by the same family for eight generations, since the mid-1800s, and this year marks their first experience with Maple High Brix. I'm thrilled we could partner with an operation like theirs: steeped in history, yet willing to try out some cuttingedge technology to help keep their business strong.

Full steam ahead for the maple industry

Looking ahead, I think we're going to see more and more of the newer sugaring setups. The maple industry is moving toward innovation. It's a little bittersweet for me and others whose personal history is connected to the way sugaring has been done for centuries. But innovation is also helping to preserve the tradition by keeping it affordable and accessible.

For Vermont maple producers who need to think about resources like time and money, and there are a lot of them, I'm proud to say we're here to help. By improving process efficiency and off-setting the cost of energy-saving equipment, we can help maple operations save time and cut fuel costs by as much as 75%.

What these businesses can then do with that savings is significant. Whether it’s investing back into their business, hiring more Vermonters, enjoying bigger profits, or just spending more time with their family, we're not just improving processes here. I like to think we're improving lives.
