Wash waters resulting from the use of cleaning chemicals for reverse osmosis (RO) membranes and evaporator pans are often strongly basic or acid, and should be neutralized before disposal in order to comply with Vermont Department of Environmental Conservation regulations. These instructions for neutralizing maple wash water will allow you to modify your used maple cleaner to a safe pH range.
A test of vapor compression distillers for processing maple syrup revealed that: (1) vapor compression equipment tested evaporated 1 pound of water with .047 pounds of steam equivalent (electrical energy); open-pan evaporators of similar capacity required 1.5 pounds of steam equivalent (oil energy) to produce 1 pound of water: (2) vapor compression evaporation produced a syrup equal in quality to that from a conventional open-pan evaporation plant; and (3) a central plant producing 8,000 gallons of syrup per year should yield a return of 16 percent on investment. Increasing annual product output should increase the return on investment.
Dr. Tim Perkins, Director of UVM’s Proctor Maple Research Center, shares a review of the past year at PMRC and a collection of recent findings on topics related to sap and syrup production.
A new research facility designed and dedicated to the study of the effects of sap processing equipment and techniques on the chemistry and quality of maple syrup is being constructed at the UVM Proctor Maple Research Center. This facility will allow researchers to evaluate the differences in maple syrup due to changes in sap processing equipment, including reverse osmosis, evaporators, and other evaporation equipment (steam-away, air injection units, etc.).
How to build a vacuum boiler to make high-quality granulated maple sugar.
Though it is not well known, all species of walnut (Juglans spp.) produce a sweet sap that can be boiled down into valuable syrup. There is a well-established resource of black walnut (Juglans nigra) trees throughout eastern North America that could be utilized for syrup production to complement existing sugaring operations.
Today we are at the UVM Proctor Maple Research Center in Underhill Center, Vt. with center director Dr. Timothy Perkins, Jean Francois Goulet of Lapierre Equipment and Proctor’s Abby Van Den Berg, boiling on a Lapierre HyperBrix system with 35 percent concentrate. The new technology takes out 2/3rds of the water from the sap before it hits the evaporator. Lapierre donated the equipment to the Proctor center to support research. Van Den Berg’s findingsÑfollowing a blind taste test last fall with a group of volunteersÑ found there is no noticeable taste difference between syrup produced in a high brix process vs. conventional syrup.
Pure maple syrup is on the rise in a declining overall market for pourable syrups. We are moving in the right direction, but still have a long way to go.
University of Rhode Island researcher Navindra Seeram, who specializes in medicinal plant research, has found more than 20 compounds in maple syrup from Canada that have been linked to human health, 13 of which are newly discovered in maple syrup. In addition, eight of the compounds have been found in the Acer (maple) family for the first time.
These handy cards provide checklists for color, clarity, density, and flavor, with notes on why syrup may not measure up to standards.
