Abstract: The invention relates to a capsule (1) for insertion in a beverage production machine adapted to supply pressurized liquid into the capsule (1), the capsule (1) comprising at least one compartment (13) containing nutritional ingredients (14) for the preparation of a nutritional composition in combination with the supplied liquid, the capsule (1) further comprising a product delivery system (15) arranged at an outlet face (8) of the capsule (1) and designed for delivery of the nutritional composition, the product delivery system (15) comprising one or several plurality of perforating elements (16) designed to perforate a membrane (17) arranged between the compartment (13) and the outlet face (8) of the capsule (1) as a result of the pressure of liquid exerted in the compartment, wherein the perforating elements (16) each comprise three blade members (21) extending from a common axis (A).

Abstract: Drying printed material, in strip or sheet, using a drying fluid propelled in the direction of the printed material through nozzles. Each nozzle has one outlet or blowing opening to blow a drying fluid or medium which has been warmed by heating elements. The nozzles are arranged in an enclosure of a drying device. Near the printed material, the drying fluid or medium presents a turbulent flux that is immediately produced at the nozzle outlets through transformation means of a laminar flux into a turbulent flux. The drying fluid or medium is extracted from the enclosure of the drying device by an exhaust pipe located between two successive nozzles, and preferably equidistant from each of the nozzles.
