Description
Technical field
The present invention relates to a kind of container package (Scold め) beverage manufacturing method and device, be particularly related to the noncarbonated beverage products that plastic bottle cans such as can realizing the PET bottle or metal Bottle ﹠ Can normal temperature flow, for example: the weight-saving manufacturing method and apparatus of used container in the manufacturing of belly wash water, mineral water, milk, milk beverage etc.
Background technology
One of manufacture method of the noncarbonated beverage products that flows as plastic bottle can normal temperature such as former PET bottles has the manufacture method that is called as aseptic completion method, it uses bottle and vinyl cover after the sterilization, content liquid after gnotobasis, normal temperature (20～30 ℃) are filled sterilization down seals then.Employed plastic bottle in this manufacture method, after shaping, need vertical compression strength in the conveyance process till the filling work procedure with the state of empty bottle, and the goods after filling need the vertical and horizontal compression strength, and necessary bending strength need preserve sale in automatic vending machine the time.
On the other hand, consider, use the discarded bottle in back to crush easily, and take the aspect consideration, need the lightening of bottle from economical with materials from the viewpoint of environmental protection.But its rigidity can reduce when making plastic bottle lightening.For example, interior pressure after the filling is the situation of PET bottle used in the former aseptic filling of roughly identical with barometric pressure 101KPa, at the mean thickness of bottle (ボ ト Le metastomium) is 0.15mm when following, because the rigidity deficiency makes the bottle of filling after the beverage can not be piled into 3 layers (common accumulation mode of transport) on shelf.In addition, because bending strength is also not enough, thereby can not in automatic vending machine, sell.
Therefore, exploitation has proposed variously to obtain the weight-saving technology of bottle by making in the bottle simultaneously for malleation prevents bottle distortion.As one of method is the method for filling liquid nitrogen in the head space (headspace) of bottle, and there is the relatively large problem of pressure irregularity in this liquid nitrogen completion method.As other method, use nitrogen injection device such as carbonator that nitrogen is pressed into the method that made it dissolving in the beverage, described nitrogen pressing-in method exists when beverage is packed into container and is difficult to suppress the problem of dispersing, foaming.Promptly, in the aseptic filling, if the filling spout that makes bottle placer (filler) is adjacent to the inlet of the bottle that is configured in the below, then container and environment are polluted by beverage, if filling spout disposes in the mode that the inlet with bottle keeps at a certain distance away, desire will be dissolved with the liquid filling of high pressure nitrogen in container, nitrogen gas foaming in the space of filling between spout and the bottle inlet then, thereby simultaneously owing to liquid is that high pressure causes dispersing radially and is difficult to be injected in bottle inlet.Therefore also exist the method for cleaning of bottle placer self than problems such as difficulties.And also exist the nitrogen that is pressed into to release easily in the normal temperature field and be difficult to form the problem of malleation.Known only by being filled in the container after the liquid temperature that reduces beverage, and then the products temperature after the sealing that raises, thereby press in improving.But exist in this method and press not enough problem in the container.Because these reasons in aseptic completion method, are malleation by by the nitrogen pressing-in method nitrogen being pressed into still to fail in the beverage to make so far in the bottle.
The situation of heat-resisting PET bottle, disclose in the TOHKEMY 2001-31010 communique by charging into liquid nitrogen after at high temperature being filled into beverage in the bottle and made in the bottle to malleation, thereby can prevent the distortion of bottle, further can obtain the weight-saving technology of bottle, but the interior pressure of bottle is difficult to control, for compare resistance to effect of heat with heat-resisting PET bottle is nonessential, thinner aseptic filling PET bottle, Yin Qinei presses the abnormal deformation that produces bottle when causing filling beverage under higher pressure owing to interior pressure inhomogeneous, thereby can not adopt this method.
In addition, the situation of metal can, technology in the solution in the use carbonator is sealing into nitrogen is disclosed in the Japanese Patent Publication 58-55079 communique, with respect to being the metal can of rigid body substantially, with regard to regard to elastomeric plastic bottle, because interior pressure causes the expansion of bottle, it is difficult to interior pressure is set at as putting down in writing in the document.
The present invention develops in view of above-mentioned prior art problems, first purpose of the present invention provides a kind of later-model container package beverage manufacturing method and device, when selling goods, it in necessary bending strength, can also obtain the lightening of container in the vertical and horizontal compression strength of keeping container package beverage necessary container in conveyance and automatic vending machine.
In addition, in the aseptic fill system of container package food, when in the container that carries out before sealing, enclosing the malleation completion method of liquid nitrogen, in liquid nitrogen filling device, need at least the liquid nitrogen applying nozzle is arranged on gnotobasis inside with nitrogen storage tank and liquid nitrogen applying nozzle.At this moment, in common aseptic fill system, in order to keep gnotobasis in-to-in germ-free condition, regularly cleaning and sterilization is carried out in gnotobasis inside with soup, steam, sterilized water etc., therefore for example, if the liquid nitrogen filling device is arranged in the gnotobasis, then liquid nitrogen filling device itself must have the cleaning and sterilization comformability for these medicaments etc.But present situation is that it is extremely difficult making the liquid nitrogen filling device to have drug resistance or partly to implement icing countermeasure (for example making the processing of its all dry in order preventing to freeze) at utmost point low temperature.
In addition, be filled in the container, need the asepticize of liquid nitrogen itself, also need the asepticize of liquid nitrogen stream, holding vessel itself for liquid nitrogen with asepticize.In order to obtain the asepticize of liquid nitrogen, the scheme that bacterial filter is set at the liquid nitrogen supply port of holding vessel is disclosed in the TOHKEMY 2000-185710 communique, it is aseptic that but the stream of liquid nitrogen applying nozzle part is difficult to keep, and can not guarantee aseptic problem fully and exist.In addition, method with high-temperature gas aseptic of holdout device to carrying out heat sterilization in the liquid nitrogen filling device is disclosed in the above-mentioned document, but device heated needs lot of energy and time, and device needs the ultralow temperature of tolerance liquid nitrogen and two kinds of temperature of high temperature that high-temperature gas brings, thereby the broad range of the desired thermal property of parts about-200 ℃ to+200 ℃ of device, thereby the material range of choice of production part is narrow, the problem of device single-piece structure complicated.
Therefore, second purpose of the present invention provides a kind of aseptic liquid nitrogen fill method and device, it is in the aseptic fill system of container package food, after food is filled, seal in the head space that goes to container and charge into liquid nitrogen, the liquid nitrogen filling device can be arranged in the gnotobasis, and can positively realize the asepticize of nitrogen storage tank, liquid nitrogen stream and the applying nozzle of the asepticize of liquid nitrogen and liquid nitrogen filling device with simple and low-cost configuration.
In addition, the 3rd purpose of the present invention provides a kind of aseptic liquid nitrogen filling device, it is in the aseptic fill system of container package food, after food is filled, seal in the head space that goes to container and charge into liquid nitrogen, be arranged at outside the gnotobasis by a part, thereby can positively realize the asepticize of the applying nozzle of the asepticize of liquid nitrogen and liquid nitrogen filling device with simple and low-cost configuration with aseptic liquid nitrogen filling device.
