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).
Claims20
A content-filling system comprising:
- a circulation system that includes a water sterilizer configured to sterilize water without heating;
- a water tank disposed downstream of the water sterilizer and outside of the circulation system;
- and,
- a control unit that controls the water sterilizer,
- wherein the water sterilizer comprises:
- a first sterilizer that sterilizes the water;
- a first sterile filter that is disposed downstream of the first sterilizer;
- and
- a second sterile filter that is disposed downstream of the first sterile filter,
- wherein the first sterilizer sterilizes the water with an ultraviolet ray and,
- the water tank is completely filled with the water while product bottles are manufactured at the content-filling system, the control unit causes the sterilized water to be circulated in the circulation system.
A sterilizing method of sterilizing a content-filling system comprising at least one water sterilizer that sterilizes water without heating;
- the sterilizing method comprising:
- supplying hot water to the water sterilizer,
- circulating the hot water in a circulation system including the at least one water sterilizer, and
- cooling the circulation system,
- wherein the water sterilizer comprising:
- a first sterilizer that sterilizes the water;
- a first sterile filter that is disposed downstream of the first sterilizer;
- and
- a second sterile filter that is disposed downstream of the first sterile filter,
- wherein the first sterilizer sterilizes the water with an ultraviolet ray and,
- in circulating the hot water, the hot water is circulated while an ultraviolet lamp of the first sterilizer is lit.
