Description

  The present invention relates to a sterilizing agent spraying apparatus for sterilizing the inside of various containers such as liquid containers.

Conventionally, in containers for liquids such as milk and other containers, the inner surfaces of containers are sterilized with a disinfectant such as hydrogen peroxide before filling with beverages. A sterilizing agent spraying device is used for the inner surface sterilization. However, in the conventional spraying device shown in FIG. 4, the nozzle portion 14 is arranged above the center line of the container 1 with the nozzle 2 facing downward, Sprayed into the container 1. At this time, a part of the spray fine particles blows up from the inside of the container 1 due to the spray pressure, and adheres to the outer surface of the nozzle portion 14, the gas supply pipe, the sterilizing agent supply pipe and the like. If such a phenomenon is repeated, the aggregated and agglomerated fine particles may be dropped into the container 1 as a droplet 14D containing a relatively high concentration of the sterilizing agent, thereby increasing the residual concentration of the sterilizing agent. Was necessary. Reference numeral 12 denotes an outer surface of the container 1.
Japanese Patent Laid-Open No. 5-180855

  The present invention provides a sterilizing agent spraying apparatus that eliminates such problems in the conventional apparatus and does not increase the residual concentration of the sterilizing agent in the container by droplets 14D during internal sterilization. Also provided is a disinfectant spraying device in which the disinfectant is adhered to the inner surface of the container in a substantially uniform state.

In order to solve the above problems, the disinfectant spray device according to the present invention takes the following means. That is, in a sterilizing agent spraying apparatus in which a nozzle part is arranged above a container and a sterilizing agent is ejected from a nozzle hole of the nozzle part, the nozzle part is outside the upper surface of the container above the outer surface and in the container. It is arranged at a predetermined downward inclination angle.

Further, in the sterilizing agent spraying apparatus in which the nozzle part is arranged above the container and the sterilizing agent is ejected from the nozzle hole of the nozzle part, the nozzle part is outside the upper extended surface of the outer surface of the container and in the container. An auxiliary nozzle portion disposed at a predetermined downward inclination angle toward the disinfectant discharged from the nozzle hole of the nozzle portion is provided in front of the nozzle portion while being disposed at a predetermined downward inclination angle.

In the sterilizing agent spraying apparatus according to the present invention, the nozzle part and / or the auxiliary nozzle part are arranged outside the upper extended surface of the outer surface of the container, and the sterilizing agent is provided on the outer surface of the nozzle part, the auxiliary nozzle part, the gas supply pipe, etc. Even if a droplet containing s is produced, it does not fall into the container, so that the residual concentration of the bactericide is not increased. In addition, an adjustment function by the auxiliary nozzle unit installed corresponding to the nozzle unit, that is, a gas such as air is ejected from the nozzle port of the auxiliary nozzle unit toward the air current of the sterilizing agent ejected from the nozzle port of the nozzle unit. Change or adjust the diffusion direction, state, etc. Thereby, the disinfectant is adhered to the inner surface of the container in a substantially uniform state, and the container can be reliably sterilized.

The best mode for carrying out the present invention will be described with reference to FIGS.
In the sterilizing agent spraying apparatus A shown in FIG. 1, the nozzle part 4 is arranged above the container 1, and the sterilizing agent is ejected from the nozzle hole 2 of the nozzle part. The nozzle unit 4 is connected to a transport pipe for supplying a sterilizing agent such as hydrogen peroxide in the tank and a gas supply pipe for supplying a gas such as air (not shown), and the hydrogen peroxide supplied by the transport pipe. A sterilizing agent such as is sprayed from the nozzle 2 of the nozzle unit 4 in the form of a fine particle airflow (see the broken line in FIG. 1). The cylindrical bottomed container 12 has an upper opening 5 formed at the upper end of the outer surface 3. The nozzle portion 4 is arranged outside the upper extension surface 12A of the outer surface 12 of the container (the right side of the imaginary line 12A in FIG. 4, the same applies hereinafter).

  The nozzle portion 4 is installed in the container 1 at a predetermined downward inclination angle. That is, the nozzle part 4 is arranged such that an extension line of the central axis 4B thereof is arranged at a downward inclination angle α with respect to the center line 12B of the container 1, and the sterilizing agent is sprayed obliquely downward into the container 1 from the nozzle 2 of the nozzle part. The magnitude of the downward inclination angle α is appropriately set according to various conditions such as the position of the nozzle portion 4.

  The disinfectant sprayed from the nozzle hole 2 of the nozzle part advances and diffuses in the ejection direction and further diffuses downward by gravity and adheres to the inner surface of the container 1. Further, a part of the air is diffused and raised by the air flow in the container 1 and adheres to the inner surface of the container 1. In this way, the sprayed fine particle disinfectant adheres to the inner surface and the container 1 is sterilized. In this case, the nozzle part 4 is outside the outer surface 12 upper extension surface 12A of the container and is not exposed to the blowing air flow, and the possibility that the droplet 14D is generated in the nozzle part 4 is small. Even when the droplet 14D is generated, the dropping point is outside the container 1, and the residual concentration of the bactericide does not become a problem.

  Next, the disinfectant spray device B shown in FIG. 2 includes an auxiliary nozzle portion 15 in addition to the nozzle portion 4. A gas supply pipe is connected to the auxiliary nozzle portion (not shown), and pressurized gas such as air is ejected from the nozzle. Similarly to the above, the nozzle part 4 is arranged so that the center line 4B of the nozzle part is inclined at a predetermined downward inclination angle α with respect to the center line 12B of the container, and the disinfectant is introduced into the container 1 from the nozzle part 4. Sprayed diagonally downward. An auxiliary nozzle portion 15 is provided corresponding to the nozzle portion 4, and the nozzle hole 3 of the auxiliary nozzle portion has a predetermined downward inclination angle with respect to the air current of the bactericide discharged from the nozzle port 2 of the nozzle portion (see the broken line in FIG. 2). Installed. That is, the auxiliary nozzle portion 15 is located in front of the nozzle hole 2 of the nozzle portion, and the central axis 6 of the auxiliary nozzle portion 15 is installed at a downward inclination angle β with respect to the central axis 4B of the nozzle portion 4. The magnitude of the downward inclination angle β is appropriately selected according to various conditions such as the position of the auxiliary nozzle portion 15. From the nozzle hole 3 of the auxiliary nozzle part, a gas such as air is jetted toward the air current of the sterilizing agent ejected from the nozzle hole 2 of the nozzle part, and the progress diffusion direction and state of the sterilizing agent can be adjusted.

  As long as the auxiliary nozzle is arranged in front of the nozzle hole of the nozzle part and at a predetermined downward inclination angle, the installation position is not limited, but in the sterilizing agent spraying apparatus B shown in FIG. 2, the nozzle hole 3 of the auxiliary nozzle part. Is above the nozzle hole 2 of the nozzle part, and the nozzle hole 3 of the auxiliary nozzle part is arranged in the vicinity of the nozzle hole 2 of the nozzle part. As a result, the gas from the auxiliary nozzle unit 15 is directed to the air flow of the spray particles having a relatively low diffusivity after being ejected from the nozzle port 2 of the nozzle unit, and the germicide can be changed or adjusted in a desired direction more reliably. it can.

  That is, the disinfectant ejected from the nozzle port 2 of the nozzle part advances and diffuses in the ejection direction, while being diffused and bent downward into the container 1 by the air flow from the auxiliary nozzle part 15. The microparticles of the bactericide further fall and diffuse due to gravity and adhere to the inner surface of the container 1, while a part of the sterilizing agent diffuses and rises due to the air flow inside the container and adheres to the inside of the container 1. Thereby, the disinfectant sprayed from the nozzle part 4 is uniformly supplied into the container, and the inner surface of the container is sterilized in a uniform state.

  The auxiliary nozzle portion 15 is disposed outside the upper extension surface 12A of the outer surface 12 of the container. That is, both the nozzle portion 4 and the auxiliary nozzle portion 15 are outside the upper extension surface 12A of the outer surface 12 of the container, and even if the droplet 14D is generated in the nozzle portion 14 and / or the auxiliary nozzle portion 6, the drop point is the container. 1 and the residual concentration of the bactericide does not become a problem.

  Further, in the disinfectant spray device C shown in FIG. 3, the auxiliary nozzle portion 15 is arranged on the container facing surface 7 side in front of the nozzle portion 4 with the nozzle hole 3 facing the nozzle portion 4 side. Even when the gas from the nozzle 3 of the auxiliary nozzle part is ejected from the direction opposite to the traveling direction of the air current ejected from the nozzle hole 2 of the nozzle part, and the sterilizing agent is sprayed from the nozzle part 4 with a relatively strong pressure. The bactericide is not unevenly distributed and adhered to the container facing surface 7 in front of the nozzle hole 2 of the nozzle portion. Moreover, a disinfectant is uniformly supplied into the container 1, and the inner surface of the container can be sterilized in a uniform state. Also in this case, since the auxiliary nozzle portion 15 is disposed outside the upper extension surface 12A of the outer surface 3 of the container, even when the droplet 14D is generated in the nozzle portion 4 and / or the auxiliary nozzle portion 15, the drop point of the container 1 Outside. In addition, the specific structure of the nozzle part and auxiliary | assistant nozzle part installed in disinfectant spray apparatus A, B, C is arbitrary, A nozzle part can be made into a two-fluid nozzle, for example.

  The nozzle part 4 and the auxiliary nozzle part 15 can be fixedly arranged at a predetermined inclination angle, or the inclination angle can be appropriately changed. For example, the inclination angle β of the nozzle hole 3 of the auxiliary nozzle portion can be arranged to be changeable. By changing the inclination angle of the auxiliary nozzle portion 6 with respect to the fixed nozzle portion 4, it is possible to efficiently adjust the traveling diffusion direction and degree of the air flow ejected from the nozzle portion 14. In addition, the auxiliary nozzle portion is arranged so that the jet pressure of the nozzle 3 can be changed, and similarly, the direction and degree of the air flow can be adjusted. The change of the inclination angle of the nozzle of the auxiliary nozzle part and the jet pressure is appropriately selected from a manual change or a change by an automatic system. In this way, the inclination angle of the nozzle part and / or the inclination angle of the auxiliary nozzle part are arranged to be changeable, and the ejection pressure of the nozzle part and / or the ejection pressure of the auxiliary nozzle part are arranged to be changeable.
