FIELD: process engineering.
SUBSTANCE: proposed device comprises sealing unit (1) to house capsule (51) with stock for extraction. Said sealing unit (1) comprises first part and second part displacing relative to first one. It differs from known designs in that said first and second parts make the outlet (3) for discharge of extraction products from capsule (51). Sealing system for said device differs in that seal (61, 62) comprises at least one peripheral sealing edge abutting on capsule surface in line or strip to press capsule wall to capsule contents. Sealing edge extends inward towards extraction fluid inlet to make extraction fluid pressure press said sealing edge against said capsule.
EFFECT: perfected design.
