る殺菌方法である。That is, after the packaging material is sterilized by passing through a sterilizing solution or being sprayed with a sterilizing solution, the sterilizing solution adhering to the packaging material is removed using an air knife, a squeezing roll, or the like. Normally, it is passed through a drying process in this state and then sent to the filling and molding process, but in order to ensure complete removal,
Alternatively, in order to confirm that the removal has been completed, the surface of the packaging material is washed by soaking it in sterile water. After washing the packaging material in sterile water, it is passed through an air knife, squeezing roll, etc. again as a water droplet removal process, and then dried for 10 minutes in a drying process.
This is a sterilization method that involves blowing sterile air heated to around 0°C to dry the product.

し無菌水を入れかえる等の処置を行なう。Effect> In the sterile water used for cleaning at this time, the concentration of the sterilizing solution increases slightly due to the sterilizing solution adhering to the packaging material and cannot be completely removed by an air knife, squeezing roll, etc. If the concentration increase due to the sterilizing solution in sterile water is a small amount, the sterile water is irradiated with light such as ultraviolet rays to decompose the sterilizing solution. The slight increase in concentration due to the sterilizing solution in sterile water can be suppressed to below a set value by decomposition means such as ultraviolet rays. However, if there is a failure to remove the sterilizing solution before immersion in sterile water due to a mechanical failure or the like, the concentration in the sterile water will abnormally increase and the decomposition rate will be exceeded. The concentration of sterilizing solution in sterile water is always controlled by a concentration measuring device. If the above-mentioned concentration in the sterile water increases abnormally, the concentration measuring device will send out an alarm signal, and in order to reduce the concentration in the sterile water, the display and the valve operation will be controlled to take measures such as replacing the sterile water. Let's do it.
