    • A high pressure extraction capsule (1) for single beverage preparation has a porous hydrophobic membrane (5, 10) that acts as a barrier to fluid flow up to a certain pressure and exceeding said pressure allows for extracting the fluid with active ingredients but still acts as a barrier to particles, particularly ground herbs or roots, wherein the pore size of the membrane (5, 10) is bigger than 0.45 μm and wherein the hydrophobic membrane (5, 10) is arranged to have a surface tension of less than 40 dynes/cm. The capsule (1) comprises an inlet port (2), a compartment (3) for holding a substance with active ingredients like, e.g. ground herbs or roots, an outlet port (4) and a hydrophobic membrane (5, 10) that separates the compartment (3) from the outlet port (4).
    • 用于单一饮料制备的高压提取胶囊(1)具有多孔疏水膜(5,10),其作为阻挡流体流动至一定压力的屏障,超过所述压力允许用活性成分萃取流体,但仍然起作用 作为对颗粒,特别是地面草药或根的屏障,其中膜(5,10)的孔径大于0.45μm,并且其中疏水膜(5,10)布置成具有小于40的表面张力 达因/厘米。 胶囊(1)包括入口(2),用于保持物质的活性成分的隔室(3),例如, 地面草药或根,出口(4)和将隔室(3)与出口(4)分离的疏水膜(5,10)。
