Abstract: Sap-collecting devices, systems and methods for sap-producing saplings are disclosed. The saplings each have at least one stem, which is cut to form a top end at a reasonable height above ground. The sap-collecting system includes a sap-collecting device that fits over the top end and forms a vacuum-tight seal with the stem. The sap-collecting device includes an interior and an access port open to the interior. The access port can be connected to a line system. A vacuum system is operably connected to the line system and forms a vacuum within the sap-collecting device. This serves to draw the sap from the top end of the sapling, through the sap-collecting device, through the line system and to a collecting tank. A plantation growth, management, and sap-collecting system that comprises the sap-collecting system and a stand of saplings is also disclosed.

Abstract: A maple syrup production spout assembly (10) with a backflow check valve (79) is disclosed. The spout assembly is designed for use with vacuum-based maple syrup productions systems (200) and is used to prevent the backflow of sap (270) into the maple tree (100) and thus prevent the drying out of the taphole (110) due to microbial contamination. Certain existing maple production spout assemblies can be retrofitted to form the backflow check valve spout assembly disclosed herein. Methods of using the spout assembly in maple syrup production are also disclosed.

Abstract: A dual-line spout for maple syrup production is disclosed. The spout has a nose section with an input channel, and an interior chamber having first and second flow paths each fluidly connected to the input channel and to respective first and second output channels. The spout is designed for use with vacuum-based maple syrup productions systems that use a dual-line line system. The dry-line portion of the line system fluidly connects to the first output channel and the wet-line portion of the line system fluidly connected to the second output channel. Example spouts have no chambers, a single chamber or two sub-chambers, to facilitate air-liquid separation. Methods of using the spout in a vacuum-based, dual-line maple syrup production system are also disclosed.

Abstract: A line system for a maple syrup production system, where the lateral lines have an inside diameter greater than 5/16? nominal and less than or equal to ¾? and the lateral line fitting and mainline fitting have a nominal inside diameter of greater than 0.225? and less than or equal to 0.70?. Further, the line system has drop lines with an inside diameter greater than 5/16? nominal and less than or equal to ¾? and the spout fitting has a nominal inside diameter of greater than 0.225? and less than or equal to 0.70?. The increased inside diameters of the drop lines, lateral lines, spout fittings, lateral line fittings and mainline fittings dramatically improves the flow of air and sap from the taphole and through the line system.

Abstract: A maple syrup production spout with an interior chamber is disclosed. The spout is designed for use with vacuum-based maple syrup production systems. The interior chamber serves as a reservoir that allows the vacuum to accumulate, thereby facilitating the flow of sap from the tap hole, through the spout and into the dropline. The interior chamber also facilitates reduced liquid-liquid contact between the tubing system and the taphole, which improves the cleanliness of the tap hole and increases sap yield. Methods of using the spout in maple syrup production system are also disclosed.
