Although a number of factors affect maple sap flow in vacuum tubing systems, it has become increasingly apparent that sap yields are largely a function of two major influences: vacuum level at the taphole and taphole and tubing sanitation.
Since check valve adaptors and spouts reduce sap backflow, this research studied whether or not dropline replacement is as important to improving sap yield when using these taps.
Patrick Fry (Ag engineer with VT Agency of Ag. Food and Markets) covers issues related to maple operations and possible water quality issues. This presentation discusses easy (and cheap) solutions for mitigate most concerns the VT Agency of Agriculture (VAAFM) and Agency of Natural Resources (ANR) may have. The talk also covers VAAFM grant programs and how/when they may be applicable.
We initiated a controlled test of the effect of in-line UV light on the microorganisms in free-flowing sugar maple sap that had not been treated by PFA pellets at the taphole. We also wanted to test the effect of temperature-controlled sap storage for five intervals up to 7 days (167 h) prior to processing to syrup.
