Process for concentrating maple sap using membrane filtration
The patent US12049675B2 outlines a novel process for increasing the sugar concentration of maple sap through a series of steps involving membrane technology. The method begins by creating a vacuum on one side of a membrane, which allows for the evaporation of water from the maple sap circulating on the opposite side. This process can elevate the sugar concentration of the sap to levels exceeding 70° Brix, with specific claims detailing the ability to achieve concentrations between 65-67° Brix suitable for producing maple syrup. The process also includes options for concentrating fresh sap with lower sugar content (1-3° Brix) to higher concentrations (at least 20° Brix) and involves additional steps such as pan evaporation and the potential for drying the concentrated sap to produce maple sugar.
Further claims in the patent describe variations in the process, including the use of multiple membranes, temperature control of the sap (between 15 and 80° C), and the ability to pressurize the sap on the membrane's first side. The method allows for repeated cycles of gas removal and re-introduction to optimize pressure conditions during circulation. Additionally, the process can incorporate the collection of condensed evaporated water, enhancing efficiency. Overall, the patent presents a comprehensive approach to improving the sugar concentration of maple sap, which could have significant implications for the maple syrup industry.
