ABSTRACT:
A tartarous beverage, such as wine, containing a tartrate to be removed therefrom is conveyed from a storage container through a conduit under pressure into a first module having a semipermeable membrane. The semipermeable membrane forms two streams, a tartrate-free permeate and a concentrate containing a solution of said tartarous beverage and tartrate. The permeate stream is directed from the module through a conduit to a delivery tank. The concentrate may then be conveyed from the first module to a plurality of modules that are serially connected to each other. Each of the modules has an outlet that is connected by an intermediate conduit to an inlet of the adjacent module for the passage of the solution therethrough. The permeate stream exits from each of the modules and is collectively conveyed to the delivery tank. The concentrate is directed through the modules to provide a stronger concentration of the tartrate in the solution. The concentrate is then conveyed to a crystallizer where tartrate crystals are formed. Thereafter, the tartrate crystals are filtered from the tartarous beverage and the tartarous beverage is conducted tartrate free to the delivery tank to be admixed with said permeate to form a tartrate-free beverage. In another embodiment, an inert gas, such as nitrogen, is introduced into the flow of the supersaturated solution to form a plurality of bubbles entrained in the solution to accelerate the tartrate crystallization.
