Content-filling system and sterilizing method

A content-filling system comprising:

• a water sterilization line that sterilizes water;
• an undiluted-solution sterilization line that sterilizes a product undiluted solution;
• a water-filling device that is connected to the water sterilization line and is disposed in a first sterile chamber;
• an undiluted-solution-filling device that is connected to the undiluted-solution sterilization line and is disposed in a second sterile chamber;
• and
• a control unit that controls the water-filling device and the undiluted-solution-filling device;
• wherein the control unit causes the undiluted-solution-filling device to be cleaned with the inside of the first sterile chamber kept sterile, and
• wherein the control unit causes the undiluted-solution-filling device to be sterilized with the inside of the first sterile chamber kept sterile.

A sterilizing method of sterilizing a content-filling system,

• the content-filling system comprising:
• a water sterilization line that sterilizes water;
• an undiluted-solution sterilization line that sterilizes a product undiluted solution;
• a water-filling device that is connected to the water sterilization line and is disposed in a first sterile chamber;
• and
• an undiluted-solution-filling device that is connected to the undiluted-solution sterilization line and is disposed in a second sterile chamber;
• wherein the sterilizing method comprising:
• a step of cleaning the inside of the second sterile chamber with the inside of the first sterile chamber kept sterile, and
• a step of sterilizing the inside of the second sterile chamber with the inside of the first sterile chamber kept sterile.
