Beverage sterilisation device

Abstract

A beverage sterilisation device comprises a housing defining an inner space, and having a first and a second end. An electrically insulated fluid path-defining conduit extends through the inner space from the first end to the second end. A first electrode has a first part positioned adjacent to the fluid path and a second part extending perpendicular to the first part. A first counter electrode defines together with the first electrode a first capacitor, and a second electrode having a third part and a fourth part. The third part is positioned adjacent to the fluid path, and the fourth part extends substantially perpendicular to the third part. A second counter electrode defines together with the second electrode a second capacitor. The first counter electrode and the second counter electrode are short-circuited by an electrical connection, and a conductive device is electrically connected between the first electrode and the second electrode. A first trigger point is defined at the second part and remote from the first part, and a second trigger point is defined at the first counter electrode opposite to the first trigger point. The device further comprises an electrical activation circuit for short-circuiting the pair of trigger points and for causing an electric field to propagate from the first trigger point and along the fluid path.
