Embodiment Construction

[0039] In the embodiment shown in this specification, the packages labeled "1" are some plastic bottles. In the description of the preferred embodiments below, the bottle-shaped packages 1 are called bottles, and these bottles are placed in the package in object bay 2. Below a frame that also forms the upper limit of a sanitary room 3, various workstations 4, 5, 6 are installed from left to right, such as air flow nozzles for preheating, and then the disinfecting mixture that will be used as a disinfecting medium. Spray nozzles in case of injection, followed by various drying stations, a cutting station, a filling station 6 and a sealing station 5 by which the filled bottle 1 is sealed. In a preferred embodiment for packaging liquid food, such sealing may be accomplished, for example, with a plastic-coated aluminum foil seal. Workstations 4 and 6 are formed in pairs, i.e. two rows of bottles are always processed at the same time, for example at filling station 6, while sealin...

Abstract

A device for filling bottles with liquid foodstuff in sterile conditions wherein an intermittently driven device is provided with bottle supports arranged successively in a line in the direction of conveyance and which passes through processing stations. The device is arranged in a hygienic chamber having through openings for the containers of the inlet and outlet thereof, including at least one inlet for introducing sterilizing medium in the upper wall of the hygienic chamber. Contiguous bottle supports form a closed area within the upper wall of the hygienic chamber and gas extraction systems are disposed in the vicinity of the bottle openings and on the outside of the hygienic chamber perform as dynamic sluice elements. The growth conditions for microorganisms in the hygienic chamber are hindered even in the event the amount of sterilizing agent is reduced.

Description

(1) Technical field [0001] The invention relates to an apparatus for sterilizing and filling fluid food (such as beverages) in bottle-shaped packages, in which, an intermittently driven conveying device in a row along the conveying direction (first moving direction) has a front-rear arrangement, Carriers of packages which can pass through several workstations, the conveying device is arranged in a sanitary room provided at its inlet and outlet with openings for the passage of the packages and at least one inlet for the entry of a sterilizing medium. (2) Background technology [0002] In the prior art, for packaging, the packages are kept on some workpiece carriers, and the workpieces are intermittently transferred to various workstations by continuously rotating the conveyor belt, where the individual packages are processed, for example after opening. Filling and final sealing. The conveyor belt runs around two guide rollers, wherein the workpiece carriers on the arc of the...
