Problems solved by technology

[0024] First of all, in the known device, in terms of processing (i.e., sterilization) the closure, the optimal use of the treatment liquid is not realized; in fact, using part of the heat of the treatment liquid to realize the heating of the pipeline is a waste of energy. waste of
[0025] Secondly, the use of an excessive amount of treatment liquid relative to the purpose of sterilization (excessive flow rate and temperature of the treatment liquid itself) has the potential to damage the closure; in fact, excessive heating will be transferred to the closure; in particular, the temperature of the treatment liquid will be too high

Embodiment Construction

[0043] Referring to the accompanying drawings, numeral 1 designates equipment for sterilizing container closures, such as caps or stoppers used to seal containers, installed on containers at the end of the filling process.

[0044] Said device 1 comprises a duct 2 having a passage through which the closures pass. This duct 2 has at least one wall 3; in particular, said duct 2 has a side wall 3 which surrounds said passage through which the cover passes.

[0045] In the illustrated embodiment, said duct 2 has a rectangular section; correspondingly, said wall 3 has four faces, each of which is approximately planar.

[0046] In addition, the pipes 2 are preferably arranged longitudinally. Of course, the duct 2 does not have to be arranged in this way; in fact, said duct 2 can have a different shape, for example a duct with walls 3 that are circular in cross-section and follow a curvilinear path.

[0047] A conveyor belt (not shown) is provided in the duct 2 for transferring the...

Abstract

An apparatus (1) for sterilizing container closures comprises a conduit (2) defining a passage for the closure and having a wall (3) surrounding the passage, spraying means (4) for injecting inside the conduit (2) a sterilization fluid heated and vaporized, drying means for introducing hot air in the conduit (2) and means for capturing the exhaust fluids exiting from the con-duit (2), said means comprising at least a suction hood (15) arranged over a corresponding exhaust opening (14) defined in the conduit (2) at a predetermined distance thereto, to capture the exhaust fluids from said exhaust opening (14) bay way of a draught effect.

Description

technical field [0001] The present invention relates to an apparatus and method for sterilizing container closures. Background technique [0002] As we all know, in the food industry, especially in the field of beverage aseptic filling and food aseptic packaging, containers need to be sterilized from the inside to the outside before filling. [0003] Sterilization is usually carried out using chemical agents, such as hydrogen peroxide, which can be used on various types of surfaces, such as paper, plastic, metal or organic materials. [0004] To ensure that the filling takes place under aseptic conditions, it is not only necessary to sterilize the container, but also the closure of the container, such as the cap or stopper used to seal the container at the end of the filling process. [0005] Thus, known devices for the sterilization of container closures comprise a duct having walls forming from the inside a passage for the passage of the closures. [0006] In this way, s...
