The present invention provides a method for making polyethylene glycol terephthalate (PET) heat-resisting bottle. When the hot-filling containe bottle blank is blown-up and formed, the refrigerated compressed air can be blown into the bottle interior from container bottle mouth promptly to make its internal wall be quickly cooled so as to obtain the invented hot-filling container with stable moleculare structure. It also provides a compressed are refrigerating device, including its internal structure and application.
Description
Technical field
The present invention relates to heat and irritate the preparation method of container, relate in particular to a kind of raising container when can, can bear the method and the device thereof of the heat-resisting bottle of PET of higher temperature.
Background technology
Because fruit juice, Sugared beverages (not containing vapour) or fruit, vegetables, milk wet goods food must adopt the hot filling mode to load, and grow in airtight container to prevent bacterium, cause and addle, and influence product quality, so container are heat-resisting.And traditional way typically uses glass and carries out hot filling, or adds anticorrisive agent therein, and the mode of using cold filling instead carries out can, but vial is filled with weight, shortcoming such as frangible, and it is harmful easily to add anticorrisive agent.
In recent years, the P.E.T. resin increases in the application of packaging field explosively.Main cause is that the replacement of P.E.T is worth, comprise the replacement vial, aluminium pot and other flexible film, and this resin material is through the approval of U.S. F.D.A. food and drug administration, can be used on food diet packing aspect, and that the P.E.T. bottle has more is transparent, light weight and durable characteristic, is considered to " green " resin and function that can reclaiming.Yet the general heat-resisting degree of P.E.T. bottle container is low, can not be used for the liquid of can heat, as fluid temperature is 70 ℃, container will be out of shape, require the temperature-88 that reaches ℃ and can not satisfy the pasteurization sterilization, use the drink of cold fillings so can only be used for filling drinking water, soft drink etc.P.E.T bottle container after perhaps will being shaped is handled through special processing again, make the high temperature resistant suitable hot filling of its energy, but its process complexity, production cost height and speed of production is slow.
And to produce hot filling P.E.T. bottle generally be to form the P.E.T. that can Gong propel the price of to mould embryo and mould the die cavity of making shape in mould present stage, be provided with the heater that impels mold heated around the die cavity, in heater, all around locate near die cavity, be provided with cooling line, and pass to outside the mould by arm, so that pass to cold water and compressed air.During production, after the container blowing moulding, in cooling line, lead to the heart cold water in several seconds, and then passed through several seconds again with compressed air, mold cavity temperature is on every side lowered the temperature rapidly, to impel the P.E.T. resin to generate comparatively stable molecular structure, can bear higher temperature and not yielding.And after the mold temperature reduction, also need immediately with its intensification, so that blow molding, so not only a large amount of consumes energy, extend manufacture cycle, increase production cost, and, making it cooling owing to cold water, cold wind are to pass to bottle by the higher die cavity entity of temperature, its cooling effect and speed are all not remarkable.
Summary of the invention
Purpose of the present invention aims to provide that a kind of energy resource consumption is few, cool time is short, good cooling results, can improve container when can, can bear the method and the device thereof of the heat-resisting bottle of PET of higher temperature.
The preparation method of the heat-resisting bottle of a kind of PET of the present invention, it is positioned at the PET bottle base and can makes it in the forming mould die cavity, feed the moulding of compressed air inflation by the bottle base oral area then, and then the compressed air that will freeze directly blows in the bottle by the oral area of in type container bottle, make the rapid cooling forming of container bottle inwall, obtaining comparatively stable molecular structure, thereby obtain the heat-resisting bottle of PET that can bear higher temperature and can not produce distortion.
A kind of compressed air refrigeration device of the present invention comprises refrigeration compressor and cooling tank, and cooling tank is provided with gas delivery port, and the coil pipe two-port in it connects with refrigeration compressor; Cooling tank comprises seal casinghousing, card, fin, blow-off pipe, coil pipe and is connected with compressed-air actuated breather pipe, the oral area of blow-off pipe and the bottom of seal casinghousing are connected, card is fixed on below in the seal casinghousing, the front end of breather pipe is provided with some pores, and pass the inside that card is fixedly installed on seal casinghousing, coil pipe is looped around the border of breather pipe, and fixedlys connected with card, and fin and coil pipe are installed together.
Described fin comprises stator and fin, and stator and fin are provided with the cancave cambered surface that the straight tube with coil pipe matches, and in the common cavity that constitutes, the two ends of fin also are provided with the opposite knuckle of direction with the straight tube fixed clamp of coil pipe for the two.
The oral area that described breather pipe is arranged in the seal casinghousing is what seal.
The gas delivery port of described cooling tank and air accumulator are connected.
After adopting the foregoing invention method, because the compressed air that directly will freeze blows in the container, make the rapid cooling forming of container bottle inwall, obtaining comparatively stable molecular structure, thereby the heat filling container that obtains bearing higher temperature and can not produce distortion reduces the mould temperature and need not adopt, make it the container bottle cooling, therefore can connect continuous production, thereby quicken the speed of heat filling container production and reduce production costs, increase economic efficiency.And cold air is directly to blow to container inner wall, do not need the conduction of mold cavity wall body, increased cooling velocity and cooling effect, also reduced energy resource consumption simultaneously.
After adopting said structure, because the breather pipe that is installed in the seal casinghousing is provided with some pores, in the time of like this when compressed air enters seal casinghousing in, the end that it will be by breather pipe is rapidly to scattering all around; And around breather pipe, all be provided with the coil pipe that has fin, and this coil pipe cold-producing medium that flowing, it will increase the area that contacts with compressed air by fin, so enter the interior compressed air of seal casinghousing and promptly can cool off rapidly.Card and seal casinghousing bottom are provided with one section space, the air that enters seal casinghousing is after cooling, some greasy dirts and dust will fall into the seal casinghousing bottom, flow out outside the housing by blow-off pipe then, through the compressed air of this refrigerating plant refrigeration, not only keep original air pressure, but also passed through purification like this, in the time of in it is blown into container bottle, can reduce the temperature of bottle inwall rapidly.And the present invention also have simple and compact for structure, processing and assembling easily, volume is little, be convenient to move, characteristics such as refrigerating capacity is big, coefficient of refrigerating performance is high, reliability height.
