Description

Be used for the chamber of disinfection processing and the machine and the technology of method and Production and Packaging thing
Technical field
The present invention relates to a kind of being used for, and be used for the carry out disinfection method of sterilization processing of packaging material to the chamber (chamber) of sterilization processing that carries out disinfection of the packaging material by this chamber.The invention still further relates to the machine (machine) that is used to produce the packing material (package) that comprises such chamber, and the technology that is used for the Production and Packaging thing that comprises such method.Described chamber comprise the disinfection agent concentration that is used for determining this indoor gas mixture equipment (assembly, device) and be used for keeping the device (means) that is higher than outdoor room pressure in the object exit of this chamber.
Background technology
In food industry, beverage and other products are often with the wrapper packaged of paper or paperboard based.The packing material that is used for supping is often made by package lamina material (or packing sheet products), this package lamina material comprises the outside impenetrable liquid layer of paper or back flow liner and thermoplastic, this outside impenetrable liquid layer is at least in a side of sandwich layer, and sandwich layer is formed at the packing material inboard.For oxysensible especially food product, for example fruit juice and edible oil, this package lamina material further comprises one deck gas barrier material usually.This layer is an aluminium foil in most cases, and it can also cause the sealing of this package lamina material.
This packing material is made in the packer of being everlasting, and in this machine, (sheet, web) closure forms pipe to the thin plate of package lamina material with superimposed form sealing-in by the longitudinal edge with this plate.The pipe of this vertical sealing-in is by the product of packing into continuously, and transverse sealing wherein forms " pad " of filling then.This transverse sealing forms along seal area narrow, horizontal, that separate each other.After transverse sealing, by the cutting sealing district described " pad " remainder with pipe is separated, and finally form required shape.
At present, also usually there is so-called cardboard bottle (carton bottle) to be used for packing material.In itself, they are by constituting with the bottom of the sleeve pipe form of above-mentioned the same package lamina material and the top that is provided with vinyl cover (plastic top) form of opening member (as medicated cap).The cardboard bottle is often made by packer, and wherein the thin plate of package lamina material (so-called blank) is by forming pipe with two relative edges with superimposed form sealing-in.Then, each pipe is filled in vinyl cover separately, and with it so that the major part of vinyl cover outstanding mode from pipe is provided with.With Gai Yuguan after the contact surface sealing-in between them, this packing material is filled, and to form sleeve pipe and to seal this packing material, forms the shape of expectation in the sealing of the opening of pipe at last.
Above-mentioned production technology is known, and therefore is not described in detail.
In order to prolong the storage life of packaging product, prior art is before stocking process, also sometimes before forming process to the packaging material sterilization that carries out disinfection.The storage life and the packing material that depend on expectation still are dispensing and storage under normal temperature environment in cold storage environment, can select different disinfection levels.
A kind of mode of known disinfection packaging material is chemical disinfection sterilizations.For example, can make the liquid bath of packaging material, carry out the chemical disinfection sterilization through a heating clamber then through a hydrogenperoxide steam generator.In this heating clamber, the filtrated air of heat is introduced into the degree that makes the hydrogen peroxide evaporation and leave package material surface so that packaging material are heated to.
Said method is the effect excellence when successive package lamina material thin plate being carried out disinfection sterilization, but then obviously not too suitable when the opening cardboard bottle before feeding being carried out disinfection sterilization.
For the cardboard bottle, can sterilize with so-called gas phase replaces.This disinfection can be used for pre-warmed preheating chamber by the cardboard bottle is passed, the gas treatment chamber of gaseous hydrogen peroxide is housed, and then is undertaken by draft chamber.In draft chamber, the cardboard bottle is exposed in the hot filtrated air stream to remove residual hydrogen peroxide.The gas phase sterilizing unit that is applicable to cardboard bottle disinfection can be known from Swedish patent 0203692-9, and its content is incorporated in herein as a reference with way of reference.
For the suitable disinfection of packaging material, under the situation that peroxide is bathed, the concentration of accurately controlling hydrogen peroxide in the interior admixture of gas of heating clamber is vital.If concentration is too low, the hydrogen peroxide volatilization that then is applied on the packaging material is too fast, causes the inadequate danger of disinfection.On the other hand, if concentration is too high, the hydrogen peroxide volatilization that then is applied on the packaging material is too slow, the residual danger of unallowed peroxide when causing packaging material to leave heating clamber.Similarly, under the germ-resistant situation of gas phase, the concentration of accurately controlling hydrogen peroxide in the indoor admixture of gas of gas treatment is vital.If concentration is too low, then there is the inadequate danger of disinfection.In addition,, the danger of too many peroxide is arranged when then existing the cardboard bottle to leave gas treatment chamber, therefore, the residual danger of unallowed peroxide is arranged when existing the cardboard bottle to leave draft chamber if concentration is too high.Under above-mentioned any situation, if the concentration of peroxide not in certain limit, then the setting of packer should be changed.
The mode that a lot of detection peroxide concentrations are arranged.In the known packer that has an above-mentioned bath of hydrogen peroxide, the concentration of hydrogen peroxide in heating clamber in the admixture of gas is based on the consumption of concentration, hydrogenperoxide steam generator of hydrogen peroxide in the solution and the MAF in the heating clamber by control system of machine and definite.Therefore, the concentration of hydrogen peroxide is here calculated by known external parameter in theory.This is uncertain in a way assay method, and relates to the definite danger of concentration of mistake, therefore relates to the danger of false alarm.
In known packer with above-mentioned gas process chamber, the concentration of hydrogen peroxide in the indoor admixture of gas of gas treatment is measured by means of the IR-pick off.Yet such sensor bulk is big, fragile and cost is high.
Summary of the invention
An object of the present invention is to provide a kind of being used for to the carry out disinfection chamber of sterilization processing of the packaging material by this chamber, the machine that is used for the Production and Packaging thing that comprises such chamber, be used for the carry out disinfection method of sterilization processing of packaging material, and comprising that such method is used for the technology of Production and Packaging thing, it eliminates the possible limitation of prior art at least in part.Basic design of the present invention provides a kind of improved disinfection processing scheme, measures by the direct temperature and pressure in actual disinfection environment and determines the disinfection agent concentration.This direct mensuration ratio is more accurate based on the Theoretical Calculation of external parameter, and provides result more accurately.Therefore, this means the danger that has reduced false alarm.In addition, this mensuration is than more superior by the mensuration of IR-pick off, can be durable relatively and volume is little because be used to measure the device of temperature and pressure.And this device is more cheap.

The specific embodiment
In Fig. 1, show according to predetermined technology and be used for machine 10 by the tube (not shown) Production and Packaging thing of package lamina material.Package lamina material is the initial type of describing, that is, it comprises the skin of refill layer, aluminum gas barrier layer and thermoplastic.As beginning describedly, this pipe is to form by the longitudinal edge with the thin plate of partly overlapping form sealing-in package lamina material 12.After shaping, pipe by dress with the product of needs, transverse sealing at regular intervals then." pad " that form thus remainder with pipe is separated, form the shape of expectation at last.Progressive forming, filling and the sealing of such a pipe are known, and are not described in detail at this.
Before forming pipe, make the thin plate 12 of package lamina material be sterilized sterilization.For this reason, by means of guide reel 14 and 16 with the groove 18 of thin plate 12 guiding by hydrogenperoxide steam generator is housed.For example, this groove can be any disclosed in the applicant's the Chinese patent application 200510069635.8 and 200510133873.0, it is integrated with herein as a reference with way of reference at this.
After leaving groove 18, thin plate 12 is by between two squeegees 20, hydrogenperoxide steam generator expanded to equably the whole width of thin plate 12 and to remove unnecessary peroxide.Then, the thin plate 12 that has the hydrogenperoxide steam generator drop passes through heating clamber 26 by guide reel 22,24 guiding, removes hydrogen peroxide with further evaporation.Thin plate 12 28 enters heating clamber 26 and goes out from exporting 30 by entering the mouth.
Heating clamber 26 comprises heater, and its frame table that schematically draws with dotted line among Fig. 1 shows and is labeled as 32, is used to promote to be applied to the evaporation of the hydrogenperoxide steam generator on the thin plate 12.Heater 32 for example can be the type described in the applicant's Chinese patent application 200510069630.5, integrates with herein as a reference with way of reference at this, and it can be configured to the filtrated air of heat is incorporated in the heating clamber.Hot-air is meant that its temperature is enough to evaporation (vaporization) employed disinfectant (being hydrogen peroxide) here.In addition, heater 32 is configured to maintenance heating clamber 26 internal pressures higher than outdoor (except the groove).In the part of groove, promptly in the right-hand component of Fig. 1 mid-board (partition wall or dividing plate) P, pressure equates with the heating clamber pressure inside basically, and the left-hand component of the partition wall P of groove is essentially atmospheric pressure.After leaving heating clamber 26, thin plate 12 passed through medial compartment 34 before managing shaping, fill and sealing generation.
In order to realize the suitable disinfection of thin plate 12, the environment of carefully controlling in the heating clamber is extremely important.Especially, the concentration of often measuring hydrogen peroxide in the interior admixture of gas of heating clamber is necessary, and this admixture of gas is formed from the evaporable gaseous hydrogen peroxide of package lamina material thin plate by air with by heating clamber 26 time.Concentration of hydrogen peroxide in the heating clamber depends on a plurality of different parameters, enters the flow of this chamber as the filtrated air of the consumption of solution in the concentration of hydrogen peroxide in the solution in the groove, the groove and heat.If the concentration of hydrogen peroxide in the heating clamber is too high, there is the danger of unallowed residual peroxide when then existing thin plate to leave heating clamber.On the other hand, if the concentration of hydrogen peroxide in the heating clamber is too low, then there is thin plate inadequate danger of disinfection when leaving this chamber.If concentration of hydrogen peroxide is not in predetermined limits, the setting of machine should preferably be adjusted.
In view of the above, heating clamber 26 also has equipment 36, is used for determining the concentration of admixture of gas hydrogen peroxide in the heating clamber 26.Equipment 36 comprises the measurement catalyst-assembly 38 of the ceramic material sheet form that is immersed in precious metal solution such as the platinum solution.This material piece has the cuboid profile.A plurality of basic on cuboid, vertically arrange abreast for the groove of square cross section (channel), and occupy the whole inside of measurement catalyst-assembly 38.This structure is given this measurement catalyst-assembly 38 clathrate cross section in the horizontal.
Measure catalyst-assembly 38 and surrounded by the lagging casing of a pipe 40 forms, this shell is by glass and Teflon
Figure A20071008731500161
Mixture make, it radially with on the length direction all has very poor heat conductivity pipe.The inside dimension of this pipe makes that corresponding to the external dimensions of measuring catalyst-assembly measuring catalyst-assembly almost occupies whole pipe in the horizontal.The major part of measuring catalyst-assembly 38 and heat-insulated pipe 40 is arranged in such a way in heating clamber 26, so that measure the outside that the outlet 42 of catalyst-assembly 38 is connected directly to heating clamber, more particularly, be connected to medial compartment 34, and the inlet 44 of measurement catalyst-assembly is connected directly to the inside of heating clamber.
The elevated pressures of heating clamber inside forces hydrogen peroxide and AIR MIXTURES by outlet 30 and pipe 40, and therefore also by measuring catalyst-assembly 38.Because the structure of groove 18, so there is not admixture of gas 28 to leave heating clamber basically by entering the mouth.When admixture of gas when measuring catalyst-assembly 38, hydrogen peroxide according to following formula with spontaneous water and the oxygen of resolving into of exothermic reaction:
H 2O 2(g)→H 2O(g)+1/2O 2(g) ΔH Det＝23.44kcal/mol
Because measurement catalyst-assembly 38 is arranged in the heat-insulated pipe 40 and in heating clamber 26, measures in the catalyst-assembly 38 so the portion of hot that produces is retained in, and causes its temperature inside to raise.Suppose that heat loss is zero, temperature raises and how much being directly proportional that hydrogen peroxide decomposes in measuring catalyst-assembly, that is:
c H 2 O 2 = k 1 · ΔT + α , α=0. wherein
Entering the hydrogen peroxide of measuring catalyst-assembly 38 needn't inside all decompose.Depend on multiple different parameters with the decomposition of hydrogen peroxide in measuring catalyst-assembly that percentage ratio is represented, as mass flow and the physical property of measuring catalyst-assembly and heat-insulated pipe by the measurement catalyst-assembly.For one and identical device, cause hydrogen peroxide decomposition to a certain degree therein by some mass flow of measuring catalyst-assembly.Therefore, between concentration of hydrogen peroxide and temperature, there is a specific linear relationship, that is, and for each mass flow
Figure A20071008731500172
In the top equation a specific k is arranged all 1Value.More specifically, experiment shows k 1Be by managing the linear function of 40 mass flow, promptly
k 1 = k 2 · m · + β , It obtains c H 2 O 2 = ( k 2 · m · + β ) · ΔT
Because
Figure A20071008731500183
～(approximating) is along the pressure drop of heat-insulated pipe, so above equation can be write as again:
c H 2 O 2 = ( K 3 · Δp + β ) · ΔT
By means of experiment, confirmed that above-mentioned relation coincide with actual fine.Certainly, constant k 3, β value depend on the environment of existence, as the characteristic of equipment therefor, and under each situation, must determine by correction with the value of known variables.
Therefore, if measure that temperature in the catalyst-assembly raises and be known along the pressure drop of heat-insulated pipe, then the concentration of hydrogen peroxide in the admixture of gas can easily be calculated in heating clamber.In view of the above, equipment 36 further comprises the temperature device of thermocouple type, be used to measure in first temperature of the pipe inside at inlet 44 places of measuring catalyst-assembly and measuring second temperature that catalyst-assembly exports the pipe inside at 42 places, and the pressure apparatus 48 of differential pressure gauge form, be used to measure first pressure and second pressure outside the heating clamber 26, the pressure in the medial compartment 34 more specifically in the heating clamber 26.Pressure measxurement makes that might guarantee to measure catalyst-assembly operates in the effective mass flow scope of following formula.In addition, equipment 36 comprises the blood processor 50 that is connected to temperature device 46 and pressure apparatus 48, is used for according to following formula, determines the concentration of heating clamber hydrogen peroxide according to the temperature difference Δ T between first and second temperature and the pressure differential Δ p between first and second pressure
Figure A20071008731500185
As mentioned above, entering the hydrogen peroxide of measuring in the catalyst-assembly 38 needn't all decompose therein.In fact, in order to guarantee above-mentioned linear relationship, wish the hydrogen peroxide incomplete decomposing.This means that measuring catalyst-assembly 38 can manufacture less.Enough guarantee peroxide breakdown completely greatly if measure catalyst-assembly, just have peroxide to decompose fully at the middle part of catalyst-assembly, this can cause not having the danger of heat in the end generation of measuring catalyst-assembly.Even it is very little to measure the heat loss of catalyst-assembly, yet also exist dangerously like this, and will cause at decomposition point fully and measure the temperature drop between the exit of catalyst-assembly and influence the mensuration of concentration.In a word, incomplete decomposing means that hydrogen peroxide will not only pass through the outlet 30 of heating clamber 26, and arrives medial compartments 34 by measuring catalyst-assembly 38.Because clearly, do not wish gaseous hydrogen peroxide is put in the atmosphere.For this reason, the outlet 52 of medial compartment 34 is connected to major catalyst device 54 (schematically showing) and is used for the decomposition of hydrogen peroxide before discharging.The elevated pressures that admixture of gas in medial compartment is kept in the medial compartment is ordered about by outlet 52 and major catalyst device 54, enters in the atmosphere then.Major catalyst device 54 is more large-scale measurement catalyst-assemblies 38, will be not described further at this.
In Fig. 2, show according to predetermined technology, be used for from the machine 56 of tubular wrapping laminated material Production and Packaging thing.Also the machine of description is identical in the above with shown in Figure 1 aspect most of for machine 56.Only describe as much as possible below with regard to machine 56 and machine 10 different appropriate sections.
Machine 56 comprises heating clamber 58, and package lamina material thin plate 60 is conducted through this chamber 58 by guide reel 62,64, so that remove hydrogen peroxide by evaporation.Heating clamber 58 has and is used for promoting heater 66 that evaporates and the equipment 68 that is used to measure the concentration of hydrogen peroxide of admixture of gas in the heating clamber 58.Equipment 68 comprises the measurement catalyst-assembly 70 with above-mentioned measurement catalyst-assembly 38 same types.This measurement catalyst-assembly 70 is surrounded by heat-insulated pipe 72, and this heat-insulated pipe 72 is by glass and Teflon
