System for producing beverages by infusion

摘要

The system (10) has a sealing device (60) with an upstream sealing unit (61) to selectively prevent or enable access to packaging (1) in an infusion chamber (7). A downstream sealing unit (62) selectively receives the packaging in the chamber or enables egress of the packaging from the chamber by gravity. The sealing device is arranged such that the position of the upstream sealing unit determines the position of the downstream sealing unit and vice versa. The sealing units are integrated with each other. An independent claim is also included for a method of preparing a beverage by infusing a product in a packaging.
