TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an apparatus for continuously performing gas replacement, filling, and sealing by storing contents subjected to aseptic processing such as soft drinks, milk drinks, cooked rice, prepared foods, and the like in a container such as a sterile cup or tray-shaped container.
[0002]
[Prior art]
Conventionally, for example, in Patent Document 1, a container such as an opened cup and its lid material are continuously supplied into a sterile chamber maintained at a positive pressure by nitrogen gas, and the container is sterilized in the sterile chamber to remove the contents. An aseptic filling machine is known which fills a container and replaces and seals the head space of the container with nitrogen gas.
[0003]
[Patent Document 1]
JP-A-2-45323
[Problems to be solved by the invention]
In an aseptic filling machine, it is necessary to reduce the oxygen concentration in the head space by replacing the gas in the head space of the container in order to sterilize the container and prevent oxidation of the contents. However, in the above-mentioned conventional aseptic filling machine, the aseptic chamber is provided not only for the portion for sterilizing the container, filling the contents, and sealing the lid, but also for almost the entire filling machine including the chain conveyor for transferring the container. Requires an extremely large sterile space, and if both sterilization and oxygen concentration reduction are to be performed using nitrogen gas, a large amount of nitrogen gas must be supplied. Sterilization is performed by blowing sterile air into the container, and only gas replacement of the head space for reducing the oxygen concentration is performed with nitrogen gas.
[0005]
However, in this apparatus, since the gas replacement of the head space is intended to replace the sterile air existing in the head space with nitrogen gas, air is inevitably left in the head space, so that the gas replacement efficiency is reduced. And the residual oxygen concentration in the head space cannot be reduced to about 2% or less.
[0006]
When the contents of the container are contents sensitive to oxygen, such as coffee and tea, it is not possible to sufficiently prevent oxidation if the residual oxygen concentration in the head space is about 2%. Inability to accommodate aseptic filling of oxygen sensitive content.
[0007]
Further, since the above-described conventional aseptic filling machine has a wide aseptic room, when a container is sterilized by spraying a sterilizing agent in the aseptic room, a sterilizing zone is widened and the sterilizing agent is scattered in a wide space. For this reason, the consumption of the disinfectant increases, which is uneconomical.
[0008]
The present applicant proposes a continuous aseptic packaging device by a magnetic force transfer method for solving the problems of the conventional aseptic filling machine disclosed in Japanese Patent Application No. 2002-216287 in order to solve the problems of the conventional aseptic filling machine. did.
[0009]
This continuous aseptic packaging device is a continuous aseptic packaging device that fills a container in which the inside is replaced with a sterile gas other than the atmosphere with an aseptic content, and seals the container with a sterilized lid material. A sterile chamber that movably accommodates a container receiving member that holds the containers arranged at intervals, a gas replacement device that replaces the atmosphere in the sterile chamber with a sterile gas other than the atmosphere, and a magnet provided in the container receiving member. A container receiving member driving conveyor provided outside the sterile room, and a magnet attached to the conveyor at the predetermined interval in the traveling direction of the conveyor so as to correspond to the magnet provided to the container receiving member. And a magnet provided on the container receiving member and having a polarity opposite to that of the magnet.
[0010]
According to this device, only the container and the container receiving member move in the sterile room, and the driving of the container receiving member is performed from outside the sterile room. Therefore, the volume of the sterile room is significantly reduced as compared with the conventional aseptic filling machine. Therefore, both sterilization of the container and gas replacement of the headspace can be performed simultaneously with nitrogen gas without impairing economic efficiency. Therefore, the gas replacement of the head space is not performed with the nitrogen gas in the state of being surrounded by air as in the related art, but with the replacement of the nitrogen gas in a substantially nitrogen gas environment. 0.5% or less.
[0011]
[Problems to be solved by the invention]
In the apparatus using the magnetic force transfer system, it has been found that the container receiving member is exposed to the outside air when it leaves the sterile room, so that there is a possibility that falling bacteria and the like may adhere to the container receiving member.
[0012]
SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved aseptic filling and sealing device that can solve the problems of the aseptic filling and sealing device by the magnetic force transfer method.
[0013]
[Means for Solving the Problems]
The aseptic filling and sealing device that achieves the above object of the present invention is a sterile filling and sealing device that fills a sterilized container with a sterile content and seals the container with a sterilized lid.
A first sterile chamber that movably houses a container receiving member that holds the container,
A conveyor provided outside the first sterile room and driving a container receiving member by a magnet;
It is characterized by comprising a first sterile room and a second sterile room surrounding the conveyor.
[0014]
In one aspect of the present invention, the second sterile room is arranged so as to share a top plate with the first sterile room.
[0015]
In still another aspect of the present invention, the first sterile chamber includes a container receiving member receiving portion that covers a container receiving member including a top plate, both side plates, and a holding plate having a central portion opened in a longitudinal direction; It is characterized in that it comprises a bottom plate and a container accommodating portion for covering the container composed of both side plates so as to protrude downward from the opening of the plate.
[0016]
Still another aspect of the present invention is characterized by further comprising a gas replacement device for replacing air in the first sterile room with nitrogen gas.
[0017]
Further, another aspect of the present invention is characterized by further comprising a sterilizing device for sterilizing the container receiving member and / or a cleaning device for cleaning the container receiving member.
[0018]
[Action]
According to the present invention, the aseptic filling and sealing device surrounds the conveyor and the container receiving member held by the conveyor, and includes the second aseptic chamber into which aseptic air is introduced, outside the first aseptic chamber. The container receiving member that has exited from the first sterile room circulates in the second sterile room while being held on the conveyor, and moves again into the first sterile room. Therefore, since the container receiving member is not exposed to the outside air during the movement, there is no risk of contamination by falling bacteria or the like, and it is not necessary to add a step for completely sterilizing the container receiving member.
[0019]
Further, according to one aspect of the present invention, the second sterile chamber and the first sterile chamber share a top plate, so that the volume of the second sterile chamber can be reduced and the number of components can be reduced.
[0020]
According to still another aspect of the present invention, the first sterile chamber includes a container receiving member receiving portion that covers a container receiving member including a top plate, both side plates, and a holding plate having a central portion opened in a longitudinal direction; Since the container receiving portion covers the container including the bottom plate and both side plates so as to protrude downward from the opening of the holding plate, the minimum volume required for the container receiving member to pass through the volume of the first sterile chamber. Thus, the volume of the first sterile chamber can be further reduced, and the gas replacement efficiency can be further improved.
