摘要:
A method of producing a drink contained in a container comprising steps of heating and thereby sterilizing a tea drink having pH of 4.6 or over and containing catechin in an amount of 30 mg % or over or an acidic drink having pH of less than 4.6 and thereafter maintaining the sterilized drink at a temperature within a range from 60° C. to 70° C. and, in the meanwhile, heating and thereby sterilizing and rinsing a container on at least its inner surface with heated water having a temperature within a range from 65° C. to 100° C., filling the drink in the sterilized container at a filling temperature within a range from 60° C. to 70° C. in an environment controlled space which is separated from an outside environment and in which filling and sealing apparatuses and an environment surrounding the filling and sealing apparatuses have been heated and thereby sterilized and rinsed with heated water having a temperature within a range from 65° C. to 100° C., and sealing the container filled with the drink and thereafter cooling the container to a normal temperature of 40° C. or below.
摘要:
A method and apparatus for manufacturing pressurized packages capable of obtaining gas displacement pressurized canned goods with high accuracy of internal pressure by atomizing liquid nitrogen, and supplying it together with low temperature vaporized gases to a head space of a can. A spray device assembly (10) for atomizing and spraying the liquid nitrogen is provided in an opening of the bottom of a liquefied gas storage tank (1) formed as a vacuum heat insulating structure. The spray device assembly (10) is constituted such that a valve (2) for controlling the flow rate of liquid nitrogen, a spray nozzle (3), a liquid nitrogen flowpassage (4) extending from the valve (2) to the spray nozzle (3), a nozzle cooling tank (5) for cooling the flowpassage, and a purge device for cutting an outer peripheral portion of a nozzle and an outlet portion off from the air, so as to prevent them from being frosted, are integrally mounted on a spray body 6. The nozzle cooling tank (5) always cools the pipe 13 and the nozzle 3 by liquid nitrogen, and enables supplying of the liquid nitrogen to the nozzle having a temperature gradient to the neighborhood of a boiling point, without boiling and vaporizing it from the tank to the nozzle. The liquid nitrogen supplied while preventing of being vaporized to an orifice inlet of the spray nozzle allows to pass through a nozzle orifice in the liquid state to release into the atmosphere, thereby giving rise to a rapid vaporizing expansion immediately after moving out of the nozzle orifice, so that other liquid nitrogen still in the liquid phase state is atomized.

It is intended to provide a process for producing a packaged drink whereby filling can be performed at room temperature without resorting to using a chemical or sterile water, the favorable taste and flavor of the content can be maintained while relieving the thermal degradation thereof, it becomes unnecessary to employ a heat-resistant container or to thermally sterilize or cool after sealing, and thus both of the equipment cost and the running cost can be largely reduced. After thermally sterilizing the content to give a definite sterilization value, it is quickly cooled to room temperature and then stored in a storage tank that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. While maintaining the storage tank under positive pressure with the use of a sterile gas, the content is fed into a filling machine that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. Thus, the liquid-feeding system ranging from the storage tank to the filling machine is made a closed liquid-feeding pathway free from the invasion of air from the outside. The drink is filled into a container having been sterilized with hot water in an environment-controlled space isolated from the outside wherein the surroundings have been thermally sterilized and washed with hot water at 65° C. to 100° C.

There is provided a method for manufacturing a beverage contained in a container comprising: a container sterilizing process for sterilizing at least an inner surface of a container; a beverage sterilizing process for sterilizing a beverage; a filling process for filling the sterilized beverage in the sterilized container at a temperature within a range from 1° C. to 40° C.; a sealing process for sealing the container filled with the beverage with a sterilized cap; and a positive container-internal-pressure maintaining process made before sealing of the container for maintaining a positive internal pressure of the container after sealing, the container sterilizing process, filling process, positive container-internal-pressure maintaining process and sealing process being respectively performed in an aseptic space. There is also provided an apparatus for carrying out this method.
