Abstract

A plant for the cold aseptic bottling of a liquid in bottles with a conveyor line on which bottles are moved by at least one bottle handling machine in a sterile space which is separated by a housing from at least one non-sterile space, whereby the housing is formed by at least one circulating part and one stationary part, and whereby at the transition between these parts, a siphon seal is provided which makes possible the relative motion of the parts, which siphon seal comprises at least one annular duct that concentrically surrounds an axis of the circulating part to hold a sealing or barrier fluid on a ring-shaped wall element on the other part of the housing that extends into the barrier fluid located there, with at least one inlet for the feeding of the barrier fluid into the at least one annular duct and with at least one outlet for the discharge of the barrier fluid out of the annular duct, wherein the at least one outlet is realized in the form of an overflow that sets the level of the barrier fluid, and that the at least one inlet is connected with a reservoir, from which barrier fluid is fed continuously to at least one annular duct. Further, a plant for cold aseptic bottling, where there are a plurality of siphon seals on different levels, each at transitions between a circulating or rotating part of the housing and a stationary part of the housing.
