Problems solved by technology

In order to obtain the sterility of liquid nitrogen, Japanese Patent Application Laid-Open No. 2000-185710 discloses a scheme in which a sterilizing filter is arranged at the liquid nitrogen supply port of the storage tank, but it is difficult to maintain sterility in the flow path of the liquid nitrogen filling nozzle part, and There is a problem that sterility cannot be fully guaranteed
In addition, the above-mentioned literature discloses a method of heating and sterilizing the liquid nitrogen filled device with high-temperature gas to maintain the sterility of the device, but heating the device requires a lot of energy and time, and the device needs to be resistant to liquid nitrogen. Ultra-low temperature and high temperature caused by high-temperature gas, so the thermal characteristics required by the components of the device are in a wide range from -200°C to +200°C, resulting in a narrow range of material selection for the components and a complicated overall structure of the device. question

Embodiment 1

[0164] Using a device for absorbing nitrogen, in a tank filled with nitrogen that has been filtered and sterilized by a filter (material: PTFE 0.2 micron filter, after steam sterilization), heat-sterilized water (sterilized in UHT In the device, preheat at 80°C, sterilize at 135°C, hold for 30 seconds, and cool at 25°C) for absorption treatment. The treatment conditions were a tank capacity of 71 L, a water temperature of 25° C., a pressure of 0.5 MPa and 0.3 MPa, and 2 L / min. In addition, the inside of the absorber, the liquid supply piping, and the air supply piping are heated and sterilized in advance. Fill 510ml of water after pressure absorption treatment (headspace volume 10ml) into pre-sterilized such as Image 6 In the shown 500ml carbon dioxide bottle (average wall thickness 0.2mm, fully filled internal capacity 520ml), after filling for 30 seconds, cap and seal, then measure the internal pressure, the results are as follows.

Embodiment 2

[0169] Fill 510ml of heat-sterilized water in the PET bottle (in a UHT sterilizer, preheat 80°C, sterilize at 135°C, hold for 30 seconds, cool down at 20°C) to the pre-sterilized as Image 6 In the shown 500ml carbon dioxide bottle (average wall thickness 0.2mm, full filling capacity 520ml), then filter the liquid nitrogen that is sterilized by filter (material: PTFE 0.2 micron filter, after steam sterilization treatment, after drying) Fill only the amounts indicated in Table 2 and seal quickly with sterilized caps. The internal pressure of the bottle was measured, and the results are shown in Table 2.

[0170] Microbiological examination is carried out on the products produced using the above-mentioned manufacturing method and apparatus. After storing the product at 30°C for 2 weeks, pass the microbial inspection (full membrane filter (after filtering all the contents, store it at 30°C on standard agar medium for 1 week, membrane filter, material, cellulose mixed ester, por...

Embodiment 3

[0174] The heat-sterilized water in the PET bottle (in a UHT sterilization device, preheated to 80°C, sterilized at 135°C, kept for 30 seconds, cooled to 25°C, and then filtered and sterilized through a filter in a sterile tank Nitrogen bubbled and maintained at 301KPa) 510ml filled (headspace volume 10ml) into pre-sterilized such as Image 6 In the shown 500ml carbon dioxide bottle (average wall thickness 0.2mm, fully filled internal capacity 520ml), then fill it with liquid nitrogen treated by filter sterilization (material: PTFE 0.2 micron filter, after steam sterilization treatment, after drying) 20 mg, and then quickly sealed with a sterilized cap. The internal pressure of the bottle was measured, and the result was an average of 301KPa.

[0175] Microbiological examination is carried out on the products produced using the above-mentioned manufacturing method and apparatus. After storing the product at 30°C for 2 weeks, pass the microbial inspection (full membrane filte...

Abstract

This invention provides a process for producing a beverage filled into a container and an apparatus for carrying out this process. The production process comprises a container sterilization step of sterilizing at least the inner surface of a container, an internal solution sterilization step of sterilizing a beverage, a filling step of filling the sterilized beverage into the sterilized container at a temperature of 1 to 40 C, a hermetical sealing step of hermetically sealing the beverage filled container with a sterilized cap, and an in-container positive pressure holding step which is carried out before hermetical sealing for holding the inner pressure of the container after hermetical sealing at a positive pressure, all the container sterilization step, the filling step, the in-container positive pressure holding step, and the hermetical sealing step being carried out within a sterile space.

Description

technical field [0001] The present invention relates to a kind of manufacturing method and device of container-packaged beverage, especially relates to the non-carbonated beverage that can realize the filling of plastic bottle such as PET bottle or the filling of metal bottle can at room temperature, for example: cool drink water, mineral water, A lightweight manufacturing method and apparatus for containers used in the manufacture of milk, milk drinks, and the like. Background technique [0002] As one of the manufacturing methods of non-carbonated beverages filled with plastic bottles such as PET bottles in the past, there is a manufacturing method called aseptic filling method, which uses sterilized bottles and plastic caps in aseptic environment, normal temperature ( 20 to 30°C), filled with the sterilized content liquid, and then sealed. The plastic bottle used in this production method requires longitudinal compressive strength in the state of the empty bottle in the ...
