Improving Evaporator Efficiency

I have two forced air, wood fired evaporators and both have usually failed to boil in the front pan or within four inches of either side. I solved that spending under $50. Now the front pans boil and boiling occurs all the way to the sides, even above the side rail. What I did was relatively simple and nearly anyone should be able to accomplish it.

Shelf Life Extension of Maple Cream

Pure maple cream has a shelf life of less than one month if stored at room temperature. The maple cream may mold and physically separate into its maple syrup component during this period. The current product requires refrigeration to achieve an acceptable shelf life of 6 months. Our goal was to develop a process to attain 6 months shelf life at room temperature.

Weather Forecasts for Maple Producers

Weather conditions are the single most important factor affecting sap production in the sugar maple. Weather forecasts, therefore, can be a very valuable tool for maple syrup producers.

A History of Taps and Tree Size

The current ‘traditional’ tap hole number guidelines involve adding a tap for each 5 inch dbh above 10 inches dbh. ‘Conservative’ guidelines involve placing one tap in trees 12 inch dbh and a second tap in trees more than 18 inches dbh. The reasons behind the traditional guidelines are not stated in the North American Maple Syrup Producers Manual, but the conservative guidelines are suggested when there is concern for tree health. The purpose of this article is discover where these guidelines came from and to re-establish the reasons why they exist.

Cultural Methods for Establishing Sugar Maple in Field Plantings

A sugar maple plantation designed to examine specific cultural practices for efficient planting and enhancement of seedling survival and growth was established in 1997 at Cornell University’s Uihlein Sugar Maple Research/Extension Field Station near Lake Placid, New York. For 6 growing seasons after planting, the performance of specific treatments including tree shelter designs, weed control mats, and combinations of treatments for seedling survival and growth were measured. Treatments that were installed in combination with weed control mats provided increased seedling survival and enhanced growth increment during the study period.

1998 Ice Storm Effects on the Health and Productivity of Sugar Bushes of Eastern Ontario

In 1998, fifteen managed sugar bush blocks with 7% to 72% ice-induced crown damage were established in eastern Ontario. Results suggest that severe ice storm damage to crowns resulted in reduced fall root starch levels and less sap production, and/or sap sweetness, and therefore lowered the syrup producing capacity of sugar maple.

Field Evaluation of the Small Diameter Spout for Maple Sap Collection

Beginning in 1999, a newly introduced maple sap spout for use in smaller diameter tapholes was evaluated at Cornell University’s Uihlein Sugar Maple Research/Extension Field Station near Lake Placid, New York. After two sap production seasons, no significant differences were found in sap volume yield and sap sugar concentration in maple sap collected with the small diameter spout compared with that of the conventional sap spouts.

Seasonal patterns of reserve and soluble carbohydrates in mature sugar maple (acer saccharum)

Sugar maple (Acer saccharum Marsh.) trees exhibit seasonal patterns of production, accumulation, and utilization of nonstructural carbohydrates that are closely correlated with phenological events and (or) physiological processes. The simultaneous seasonal patterns of both reserve and soluble carbohydrates in the leaves, twigs, branches, and trunks of healthy mature sugar maple trees were characterized. The concentrations of starch and soluble sugars (sucrose, glucose, fructose, xylose, raffinose, and stachyose) were determined.
