Brewing module and beverage-preparing machine

A brewing module for preparing a brewed beverage from a single-serve capsule has a first brewing module part and a second brewing module part (4) which can be moved, relative to the first brewing module part, between a first brewing module part position and a second brewing module part position, wherein a movement of the second brewing module part relative to the first brewing module part can be driven by a manual or motorised drive via a transmission mechanism. A capsule detection device (5) having an optical sensor for detecting optical properties of the capsule is also provided. The brewing module is characterised by a mechanically drivable blowing device (60) for generating an air stream, which blowing device is arranged to generate an air stream on the side of the window element facing the single-serve capsule. The blowing device is mounted such that it is driven by a relative movement of elements of the brewing module, which relative movement is generated by the drive or the transmission mechanism.
