Abstract

See full text

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.
