Update on the Maple Tubing Sanitation Research in Ontario
In the spring of 1998, a research project was initiated to develop alternative methods for maple produces using plastic tubing systems. Although the results are only preliminary, the development of alternative sanitation methods that may reduce reliance on chlorine is looking very promising.

UVM Proctor Maple Research Center – Update 2020
Dr. Tim Perkins presents an overview of recent research activities at the UVM Proctor Center at the 2020 Vermont Maple Conferences.
UVM Proctor Maple Research Center examines effect of spout diameter on sap yield
In order to determine the optimal approach to sap collection in their operation, maple producers need to be informed about how the choices they make will affect sap yield. One of the decisions they face is what spout size (diameter) to use.
UVM Sap Pricing Calculator
This spreadsheet can be used to determine the price per gallon paid to the seller for sap or concentrate based upon a finished syrup density of either 66.0, 66.5, or 66.9¡ Brix and calculated using the “Revised Jones Rule” which can be found at: http://www.uvm.edu/~pmrc/jones.pdf
Vacuum and Yield in Maple Production
Keys to high yield maple production.
Vacuum Sap Collection: How High or Low Should You Go?
Questions of how vacuum affects maple sap, syrup and trees have existed for many years, and these issues are perhaps more important today than ever before due to the increasing use of collection systems that can achieve very high levels of vacuum. This article will describe recent research performed at the University of Vermont Proctor Maple Research Center that was designed to answer questions about high vacuum.
Vapour Compression Evaporation
The cost of fuel in a typical oil-fired, Open Pan Evaporator (O.P.E.) for a 4000 tap operation can represent 20% of the total syrup production costs. Vapor Compression Evaporation (V.C.E.) offers a method of capturing lost energy and improving the fuel consumption of an O.P.E. Most of the energy goes up in steam and this unit will recapture lost energy to reuse.
