Definitions
- the present invention relates to a method for inerting sealed packaging for liquid, pasty, solid and powdery products; and installation of implementation.
- the target set corresponding to residual oxygen gas below 2% is very difficult to achieve on industrial packaging equipment.
- a process has been found whose inerting efficiency on industrial packaging equipment is excellent and meets the requirement for a residual oxygen gas content of less than 2% in the overhead of the packaging.
- each of these deoxygenations is carried out under an inert atmosphere, by means of two simultaneous injections of inert fluid.
- the deoxygenation or purging of empty or filled packages is carried out by means of a distribution network of said fluid with vertical injection of the fluid in the upper part of the package, directed towards the bottom of the package, and the inert atmosphere is created by injection of inert fluid distributed above the packaging.
- the packages can be subjected to a double gas purge before filling and on the other hand after filling.
- the product to be packaged can be deoxygenated by an inert gas, followed by a phase of settling of the gas bubbles.
- the fluids, liquids or gases used for the deoxygenation of the product, to be conditioned or the inerting of the packages, are designated as inert gases, that is to say fluids which feel the action is opposed to biodiimic alterations or microbiological caused by oxygen.
- the inert fluid can designate nitrogen in gaseous or liquid form, which is inert and intervenes by the anaerobic conditions which it creates with respect to microbial species. It is also possible to use with interest a bacteriostatic gas with an inhibiting effect against numerous microorganisms, such as carixai anhydride (CO 2 ), or a nitrogen-carbon dioxide mixture.
- a packaging machine comprising a section for forming packaging, a filling section and a packaging closing section, a supply circuit, the machine being supplied with product to be packaged.
- the inerting device installed on the packaging machine, comprises, according to FIG. 1 of the appended drawing, an insulation cover (1) necessary for the protection of the packaging centers any entry of oxygen, a supply circuit in inerting fluid (3) and a circuit for supplying purge fluid to the packages (4).
- the hood (1) is inerted and purged by means of a gas distribution network for the inert gas placed laterally and located above the packages, that is to say in the upper part.
- This purge and inerting system shown in Figure 2 of the accompanying drawing is formed by a ramp (5) provided with injectors (6) in the form of cylindrical tubes aligned horizontally and whose outlet openings are directed towards the top of the cover. protection (1) so as to avoid disturbances of the subsequent purging system of the upper spaces or upper part of the packages.
- the inerting device also carries a gas distribution network (7) of the gas coming from the inlet (8), with a view to gas purging of the upper or upper part of the packages.
- This distribution network or ramp (7) shown in Figure 3 of the accompanying drawing is placed immediately above the central axis of the packages (2) with injection means (9a, 9b, 9c, 9d .. .) directed downwards, aligned, and each formed of one or more cylindrical tubes 10a, 10b, possibly flattened at the end, ensuring effective purging of the gaseous sky.
- the inerting device comprises a liquid nitrogen distribution network with a view to purging the packaging.
- This distribution network or liquid nitrogen injection manifold shown in Figure 5 of the accompanying drawing comprises a pipe liquid nitrogen supply (19) possibly divisible into several circuits (19a, 19b, 19c.) provided with a trap (20a, 20b, 20c) in order to avoid the formation of gas in the distribution pipe or manifold ( 21) into which said circuits end, said ramp being located above the packaging lines and provided with injection means (22a, 22b, ... 22f, 22g) placed immediately above the central axis of the packaging.
- the cold gas from the vaporization of liquid nitrogen then purges the air present in the container. In this case, make sure that the liquid nitrogen is completely vaporized before plugging the container to avoid excessive pressurization of flexible packaging.
- the packaging inerting devices according to the invention can be installed on the packaging line between the packaging forming section and the filling section, in order to ensure the filling of the packaging in an inert atmosphere and avoid any oxygenation of the product during its flow, or before closing the filled packaging in order to inert the gaseous sky of the packaging and thus improve the conservation of the product.
- the supply circuit of the packaging machine shown in FIG. 4 of the appended drawing, comprises a means for injecting gas (11) of the injector type placed on the line (13) and (14) of the liquid or pasty and a buffer tank (15) positioned on the packaging device allows the settling of bubbles.
- An ejector another means of gas injection, can also be used on the liquid or pasty line (14) and placed at the bottom of the buffer tank (15).
- inerting techniques can be applied to the conservation of any liquid or pasty food product: beers, wines, fruit juices, drinks based on fruit juices, concentrates and syrups, milk and dairy products, oils and derivatives, lipid products. (sauce and mayonnaise). They are also applicable to products pharmaceutical and biological.
- the inerting sequence includes two stages, according to which it proceeds, the protection of the packaging against any entry of oxygen and the creation of an oxygen-free atmosphere in the front packaging area. closing of these with an inert gas, then with a gaseous purge of the gaseous sky of the packages after filling by a gas distribution network.
- the clarified wine is conveyed through the pipe (12) to the so-called "Sparger” type injector (11) and nitrogen is introduced through the pipe (13) into the said injector.
- the deoxidized wine is conveyed via line (14) to the lower part of the buffer tank (15) in which the bubbles settle, the degassed wine is drawn off via line (16) at the base of the tank (15) and between in the filling section (17) of the adding machine.
- the closing section (18) of the conditioner co-carries the insulation cover (1) previously described, a nitrogen inlet (3) for purging and inerting the gas chamber, and an inlet of nitrogen-carbon dioxide mixture (8). purging the gaseous sky from packaging.
- Red wine is conditioned at 11 °, at a temperature of 22 ° C, at a flow rate of 2 m / 3 hours.
- the installation carried out includes in particular an insulation cover of length 630 mm, width 270 mm and height approximately 300 mm; an inerting ramp for this isolation cover of the inerting device, comprising five inert gas injection tubes, made of 8-10 stainless steel, the distance between two injection tubes being 100 mm; and a ramp for purging the packaging after filling, with a length of 334 mm, comprising four double injections, constituted by 6-8 stainless steel tubes, the distance between 2 injections being 110 mm.
- Each injection is double, consisting of two stainless steel tubes, 6 mm in diameter, flattened at their ends and spaced 20 mm apart.
- the wine contains 1.2 ppm of dissolved oxygen, 1.8 m3 / hour of nitrogen is injected into the clarified wine. After this conditioning, the dissolved oxygen content of the wine is 0.6 to 0.7 ppm.
- the inerting of the cover of the inerting device is carried out by nitrogen injection, and the gas purging of the packages and of the closure using an inert gas consisting of 50% nitrogen, 50% anhydride carbonic.
- the fourth test is carried out with injection above the packaging and at the start of closing and the control is carried out after 16 hours. It has been found that the technique used makes it possible to lower the oxygen contents in the gaseous overhead of the packaging to values much less than 2%. It has been noted that the injection of an N 2 / CO 2 gas mixture causes the packaging to shrink slightly.
