Abstract
A content-filling system (10) includes a water sterilization line (50) that sterilizes water without heating, an undiluted-solution sterilization line (70) that heats and sterilizes a product undiluted solution, and a filling device (20) that is connected to the water sterilization line (50) and the undiluted-solution sterilization line (70) and that fills the water and the product undiluted solution in bottles (100).
Claims31
A content-filling system comprising:
- a water sterilization line that sterilizes water without heating;
- an undiluted-solution sterilization line that heats and sterilizes a product undiluted solution;
- a filling device that is connected to the water sterilization line and the undiluted-solution sterilization line and that fills the water and the product undiluted solution in a container;
- and
- a control unit that controls the water sterilization line,
- wherein the water sterilization line sterilizes the water by using an ultraviolet ray, and
- wherein the control unit causes the water to be discharged to a location outside the water sterilization line in a case in which an irradiation amount or irradiance of the ultraviolet ray is equal to or less than a predetermined value.
