Method for preparing a beverage from a capsule and device therefor

摘要: Method for preparing a beverage or liquid food from capsule (1) containing material (2) with substance to be extracted, wherein said has highly resiliently permanently deformable flexible diaphragm (17). The method comprises the steps of forming plurality holes (26) distributed over (17) and spraying water onto so as urge it towards inside force into through holes. size formed by piercing spikes (25) is dependent on filling level compactness capsule, thereby influencing hydraulic pressure differential (DELTAP) between two sides (17a, 17b) in order achieve automatically controlled compression (1).
