A sterilization chamber and a filling machine having a device according to the main claim are also disclosed.
Abstract:
The present invention concerns a liquid bubble eliminator in a liquid sterilant sterilization system. It comprises an enclosure (1) having an inlet (2) and an outlet (3) for a flow of liquid sterilant (10). A number of small hollow tubes (7) are placed in the enclosure (1) below a perforated plate (4). The inlet (2) and the outlet (3) are placed at the lower part of the enclosure (1). Entrained air bubbles (8) of the liquid sterilant (10) will attach to the tubes (7) and form larger bubbles that will lift towards the top of the enclosure (1). The air bubbles (8) will go through the perforated plate (4). A float switch (5) is placed on top of the liquid sterilant (10) above the perforated plate (4). The float switch (5) controls a valve (6) expelling air accumulated above the liquid sterilant (10).
Abstract:
In a packaging machine a planar web of packaging laminate is reshaped to an annular tube of packaging laminate by means of a forming section, which comprises, - a bending roller, designed to deflect the path of the planar web, - a lower forming tool, downstream the bending roller, defining an aperture through which the packaging laminate is led and given an annular shape, and - guide means between the bending roller and the lower forming tool for guiding the path of the packaging laminate. The forming section is characterized in that the bending roller is arranged slidably on a bar extending in the direction of the web path upstream the lower forming tool, such that the forming distance between the lower forming tool and the bending roller may be varied by moving the latter along the bar.
Abstract:
The invention relates to an apparatus (100) for applying drinking straws (3) on prefabricated packaging containers (17), comprising a drive means (1) for continuous belts (2) of drinking straws (3) wrapped in protective sleeves or envelopes, a conveyor (23) for moving packaging containers (17) past the drinking straw applicator (100), means (8) for separating drinking straws (3) from the belt (2), as well as means (30) for applying the drinking straw (3) on a side wall (18) of the packaging container (17). The means (30) for applying the drinking straw (3) include at least one excenter (31a, 31b) which is excentrically disposed on a shaft (32a, 32b) which is mounted adjacent the drive means (1), the excenter (31a, 31b) being, during rotation of the shaft (32a, 32b), moved from an inner position to an outer position, a drinking straw (3) being picked up a the inner position and applied on a packaging container (17) at the outer position.
Abstract:
A sensor system for measurement of a concentration of a sterilizing agent in a sterilizing device utilized in production of packages comprises a sensor (300), adapted for arrangement in a volume of sterilization gas for measurement of concentration of the same, an electronic processing circuit, for evaluation of an output from the sensor, and an I/O-unit for communication with process-control systems. The inventive sensor system further comprises a high voltage power supply for operation of the sensor, a first electrode (301), which together with a second electrode (302) arranged at a distance from the first forms a corona gap. The system utilizes measurement of electrical properties of this gap, when a voltage is applied over the gap and a corona current is flowing between the electrodes (301, 302), to determine the concentration of sterilizing agent in the gap.
Abstract:
The present invention refers to a method for assembling an electron exit window of an electron beam generating device, comprising the steps of: arranging a foil support plate (208) on a housing of the electron beam generating device, bonding a window foil (206) to a frame (214) along at least one continuous bonding line (218), thus creating an exit window sub-assembly (216), and attaching the exit window sub-assembly (216) onto the housing. The invention also relates to an electron exit window assembly.
Abstract:
The present invention concerns a packing machine (1) in which sealed packages are formed from a packaging material web (2) and a method of processing the packaging material web (2). The packing machine (1) has embossment means placed in or below an aseptic chamber (8) and above a product level (76). Before embossing the packaging material web (2) is heated to a temperature of at least 60 0C. The heating normally takes place in an aseptic chamber (8). After the embossing the packaging material web (2) is cooled to about 20 0C. The cooling is normally given by means of the product to be filled in the sealed packages.
Abstract:
The present invention relates to a system in a sterilization chamber (10) in a filling machine for producing food packages, comprising a heating means (14, 15) for evaporating a sterilization agent on a packaging web (50) that is forwarded through the chamber (10). The chamber (10) further comprises injectors (1, 2) for spraying a liquid towards hot surfaces (14, 15, 16) of the sterilization chamber (10), in order to cool down the hot parts such that less heat is transferred to the packaging material web during a short stop of the filling machine. The invention also relates to a method for the system and to a filling machine comprising the device and implementing the method.
