A container sterilizing device includes a transport mechanism that transports a container and a supply unit that supplies a sterilizing agent to the container that is being transported by the transport mechanism. The supply unit includes a nozzle for spraying the sterilizing agent. The nozzle does not move in a vertical direction and, without being inserted into the container, moves in synchronization with the container that is being transported by the transport mechanism.

Container sterilizing device, content filling system, container sterilizing method, and content filling method

To make a sterilization step appropriate in an aseptic filling apparatus. Provided is an aseptic filling apparatus including a step of sterilizing a preform and a step of sterilizing a container obtained by molding the preform, wherein assuming sterilization effects in the respective sterilization steps as X [LRV] and Y [LRV], a relationship of 5&#x2264;X+Y&#x2264;10 (where Y&#x2265;0) is established.

Aseptic filling method and aseptic filling apparatus

A step of letting a preform made of resin adsorb a sterilizer, a step of sterilizing the preform by heating the preform having adsorbed the sterilizer to a temperature suitable for a blow-molding treatment to activate the sterilizer adsorbed by the preform and a step of shaping the preform into a bottle by blowing aseptic air into the preform in a mold are performed sequentially. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.

Method and apparatus for sterilizing bottle

A heating apparatus and a heating method for preforms are provided which eliminate poor sterilization of a mouth portion of a preform to which a disinfectant has been blown. The heating apparatus includes a heating section that heats the preform is provided with a mouth portion heating section, and a mouth portion of the preform is heated to a temperature in a range of 50&#xb0; C. to 70&#xb0; C.

Heating apparatus for preforms and heating method for preforms

To provide a method and an apparatus for sterilizing a preform that can reduce the amount of the remaining hydrogen peroxide in sterilization of a preform, a sterilizer at least containing 30% by mass or less of hydrogen peroxide and a solvent having a boiling point of 85&#xb0; C. or lower is gasified, the sterilizer gas is blasted to the preform, and the preform to which the sterilizer has been blasted is heated to a temperature suitable for molding by blasting hot air or without blasting hot air. Alternatively, after the preform is irradiated with light containing ultraviolet rays, the sterilizer gas is blasted to the preform, and the preform is heated to a temperature suitable for molding.

Method and apparatus for sterilizing preform

A bottle is conveyed to a filling device without being sterilized by a container sterilizer, and a culture medium is filled inside the bottle by using the filling device. Then, the bottle is capped with a cap using a cap attachment device. Thereafter, whether or not bacteria survive or propagate in the culture medium in the bottle is verified.

Initial bacteria confirmation method in content filling system, method for verifying content filling system, and culture medium

A method of sterilizing a bottle includes steps of: sterilizing bacteria adhering to a preform () made of resin by gasifying a sterilizer, discharging a sterilized gas (G) from a nozzle () toward a preform, now traveling, so as to adhere to the preform (); activating the sterilizer adhering to the preform by blasting hot air (P) to the preform; sterilizing the bacteria adhering to the preform, and removing the sterilizer adhering to the preform (); heating the preform to a temperature suitable for blow-molding treatment; and blow-molding the preform within a mold () to mold the preform into a bottle (), wherein the above steps are performed sequentially in order. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.

It is possible to shorten a time before starting a drink filling working and a time for manufacturing a product. In a drink filling method in which a drink supply pipe line () for supplying a sterilized drink from a heat-sterilizing unit () into a filling machine () is sterilized, the drink then fills a container () through the drink supply pipe line (), and thereafter, the container () is sealed, an upstream side circulation path () is formed by forming an upstream side return path to an upstream side pipe line section () passing through the sterilizing unit of the drink supply pipe line, a downstream side circulation path () is formed by forming a downstream side return path to an downstream side pipe line section () of the drink supply pipe line extending from a downstream side portion of the upstream side pipe line section to the filling machine, an alkaline cleaning liquid is circulated within the upstream side circulation path and the downstream side circulation path to thereby clean and sterilize an interior of the drink supplying pipe line, and a drink filling working is stared after performing a rinsing treatment with water.
