发明名称 MEMBRANE VAPOUR CONCENTRATOR
摘要 <p>Apparatus for concentrating a vapour comprising: an optional vaporizer, a vapour flow conduit; a counter flow conduit; an optional humidity controlle r; and wherein at least a portion of said vapour flow conduit and said count er-flow conduit define respective opposed sides of a membrane. A plurality o f alternating vapour flow conduits and corresponding counter-flow conduits m ay be present. The alternating vapour flow conduits and counter-flow conduit s may for example be in a layered configuration or in a concentric, coaxial tubular arrangement. Also, a method of producing a concentrated active from a solution comprising an active in a solvent and having a first active:solve nt ratio, said method comprising the steps of: (1) vaporizing the solution t o form a vapour wherein the concentration of active is at about said first r atio, (2) providing a flow of the vapour to a first side of a membrane; and (3) providing an alternate flow of a gas to a second side of the membrane wh ereby to increase said first active:solvent ratio on the first side to a sec ond active:solvent ratio greater than the first active:solvent ratio.</p>
