Abstract
The process of producing concentrated maple sap can include concentrating the maple sap using membrane filtration to a sugar content of approximately 30° Brix, circulating the maple through a maple sap passage of a membrane, wherein the membrane contains the maple sap in a vacuum cavity, and evaporating the water from the maple sap across the membrane into the cavity. The concentrated maple sap having a sugar content above 50° Brix.
Claims26
A process of increasing a sugar concentration of maple sap, the process comprising:
- removing gas from a cavity on a second side of a membrane to cause a pressure below atmospheric pressure on the second side of the membrane, wherein the second side is a gaseous phase;
- circulating maple sap in liquid state along a first side of the membrane;
- and
- evaporating water from the maple sap across the membrane, thereby increasing the sugar concentration of the maple sap.
