実状である。[0003] In the manufacture of this product, the container is sterilized before filling with drinking water in order to sterilize the drinking water in the container, and the sterilized drinking water is added to the sterilized container. The product is filled and then, in many cases, subjected to a heat sterilization step to obtain a product. In addition, some soft drinks are commercialized by non-heated aseptic filling equipment such as highly controlled aseptic filling equipment, but non-heated aseptic filling requires expensive machinery and strict hygiene management. Is required, and it is necessary to perform a very special operation management. Therefore, in general, sterilization by heating is actually performed.

In the step of filling drinking water into a container, it is difficult to completely sterilize the filling environment, so that drinking water may be contaminated with external bacteria during filling. For this reason, it is necessary to further heat-sterilize the product in which the container is filled with drinking water, and this has caused an increase in the number of steps, a reduction in productivity, and an increase in cost.

熱完全無菌充填装置を提供することを目的とする。[0007] The present invention solves the above-mentioned conventional problems, prevents the incorporation of bacteria from the outside in the filling portion of drinking water, and eliminates the need for heat sterilization after filling. It is an object to provide an aseptic filling device.

0.01〜0.1MPa程度高いことが好ましい。An apparatus for filling drinking water according to the present invention is an apparatus for aseptically filling drinking water, characterized in that the filling means is provided with a positive pressure atmosphere to prevent mixing of external air. I do. In addition, it is preferable that the pressure of the filling part is higher than the atmospheric pressure by about 0.01 to 0.1 MPa.

た後の加熱殺菌処理を不要とすることができる。In this drinking water filling apparatus, the filling section in a sterile state is set to a positive pressure (positive pressure) to prevent air containing bacteria from entering from the outside, so that the apparatus can be heated without heating. As a result, the sterilization treatment can be reliably performed. That is, for example, when filling the pack with drinking water, the drinking water comes into contact with the external atmosphere at the filling section, so that the filling section is sealed so that the inside of the filling section is always in a positive pressure state and the outside air is exposed. Prevent contamination. In this case, it is preferable to supply sterile nitrogen gas, sterile air containing chlorine or ozone as the gas to be supplied to the filling section in order to obtain a positive pressure state. Thereby, the heat sterilization process after filling drinking water into a container can be made unnecessary.
【0010】なお、充填される飲料水は無菌状態である

れる飲料水を無菌化する手段を備えることが好ましい。
この無菌化手段としては、飲料水をMF膜分離処理して
除菌する手段と、その後紫外線を照射して殺菌する手段
との組み合わせが好適である。[0010] The filled drinking water is required to be in a sterile state. Therefore, the apparatus of the present invention is preferably provided with means for sterilizing the filled drinking water.
As the sterilizing means, a combination of a means for removing bacteria by subjecting drinking water to MF membrane separation treatment and a means for sterilizing the drinking water by irradiating ultraviolet rays thereafter is preferable.

It is preferable to provide a means for performing the above.

うにすることが望ましい。That is, in the case of a vinyl film pack, the film is usually wound into a roll at the time of manufacture, but since the film is not manufactured in a completely sterile environment, the film surface is not in a sterile state. Generally, the film roll is further wrapped in a vinyl film, pouched, and sterilized by irradiation with γ-rays in a cardboard box. However, the filling of the film roll sterilized in this way into the filling device is performed manually, so that the sterile environment collapses. In order to make this aseptic again, it is desirable to sterilize the film by irradiating the surface with which the film comes in contact with ultraviolet light with an ultraviolet sterilizing lamp.

できるようにすることが好ましい。By the way, the operation of such a filling apparatus is stopped for various reasons such as replacement of a film roll, maintenance, and night stop. Therefore, even if the sterilization of the drinking water and the sterilization of the container and the container material are performed as described above, there is a possibility that the inside of the device may be contaminated with microorganisms during the operation stoppage of the device. Once the piping equipment from to the filling section is contaminated, it becomes impossible to maintain an aseptic condition. Therefore, in the apparatus of the present invention, the sterilization means M
F membrane separation means, and means for sterilizing and cleaning the piping from the MF membrane separation means to the filling section of drinking water are provided so that these can be automatically sterilized and cleaned when the apparatus is restarted or periodically. Is preferable.
