Definitions

  • the present invention relates to a device for packaging dry ice in the form of carbon dioxide snow in a plastic film.
  • the invention also relates to a method of packaging carbon dioxide snow in plastic bags in a continuous and automatic manner, using said device.
  • application EP 1 186 842 describes a device for packaging carbon dioxide snow in a plastic film, comprising means for dispensing and shaping the plastic film, a carbon dioxide snow generator in the form of a tube connected to a source of liquid carbon dioxide and placed in such a way as to fill the shaped plastic film.
  • the means for dispensing and shaping the plastic film comprise a shaping sleeve for the plastic film that is placed concentrically around the carbon dioxide snow generator while leaving a free space between the shaping sleeve and the carbon dioxide snow generator.
  • the pressurized liquid carbon dioxide When the pressurized liquid carbon dioxide is released at the upper part of the carbon dioxide snow generator, it expands to atmospheric pressure and strikes the walls of the carbon dioxide snow generator, thus leading not only to the formation of a solid in powdery form, known by the name of carbon dioxide snow, at a temperature greatly below 0° C., of around ⁇ 80° C., but also to the formation of carbon dioxide in the gaseous state, likewise at a temperature greatly below 0° C., of around ⁇ 80° C.
  • the carbon dioxide snow thus obtained drops under gravity into the shaped plastic film, while the gaseous carbon dioxide escapes through the space formed between the shaping sleeve and the carbon dioxide snow generator.
  • this device has a major disadvantage which prevents it from being used continuously on an industrial scale. This is because the gaseous carbon dioxide which escapes into the space formed between the carbon dioxide snow generator and the shaping sleeve significantly cools the walls of the shaping sleeve, causing a sudden cooling of the water vapor present in the ambient air, with the resultant formation of ice crystals on the walls, particularly the outer walls, of the shaping sleeve. The formation of ice crystals prevents the plastic film from advancing along the shaping sleeve. As the moisture level in the ambient air increases, this phenomenon becomes more pronounced.
  • the objective of the present invention is therefore to overcome all or some of the disadvantages of the prior art device.
  • the invention relates to a device for packaging carbon dioxide snow in a plastic film, comprising:
  • the gaseous carbon dioxide which is formed during the generation of carbon dioxide snow, is prevented from suddenly cooling the walls of the shaping sleeve. It is thus possible to avoid the formation of ice crystals on the walls, particularly the outer walls, of the shaping sleeve. Consequently, the plastic film no longer sticks to the shaping sleeve and there are no longer any problems with advancing the plastic film due to the cooling of the walls of the shaping sleeve by the gaseous carbon dioxide formed during the generation of carbon dioxide snow.
  • FIG. 1 is a schematic view of a device according to the invention
  • FIG. 2 is a schematic view of a bagging device
  • FIG. 3 is a detail of the device shown in FIG. 1 ;
  • FIG. 4 is a detail of one particular embodiment of the invention.
  • FIG. 5 is a cross section taken on AA′ in FIG. 4 .
  • the insulating and/or heating means with which the shaping sleeve is equipped are such that they allow the surface of the wall of the shaping sleeve along which the plastic film is unwound to be maintained at a sufficiently high temperature to avoid any crystallization of the water vapor on this wall.
  • this temperature is at least ⁇ 10° C., preferably at least 0° C., and more preferably still at least 10° C.
  • the thermal insulating means can consist of at least one layer of insulating material selected from the group consisting of cork, polystyrene, glass wool, etc.
  • the layer of insulating material can be applied to the inner surface of the shaping sleeve, that is to say to that surface of the shaping sleeve opposed to the surface along which the plastic film slides. Given that this layer is in contact with the carbon dioxide gas, it is preferably not porous and can optionally be covered with a thin layer or protective skin made of a non-porous material which is preferably insulating as well.
  • the skin can consist, for example, of a metal or plastic film.
  • a free or empty space is formed between the layer of insulating material and the inner surface of the shaping sleeve.
  • the free space is a space devoid of material and filled with ambient air at atmospheric pressure, or else placed under a vacuum.
  • the inner surface of the shaping sleeve comprises, instead of the layer of insulating material or juxtaposed with the layer of insulating material, at least one layer of heating material.
  • the layer of heating material consists, for example, of an electrical resistor, or else of a hollow element filled with liquid whose temperature can be adjusted (for example eutectic).
  • a temperature sensor In the free space can be placed a temperature sensor so that the temperature of the layer of heating material can be adjusted to the desired temperature.
  • the inner wall of the shaping sleeve consists of a superposed arrangement of layers of heating and insulating materials which can be juxtaposed or separated by at least one empty region.
  • a particularly appropriate superposed arrangement consists of the successive arrangement of a protective skin, a layer of insulating material, a layer of heating material and an empty space, it being possible for the empty space to be provided with a heat sensor, the empty space being situated closest to the inner wall of the shaping sleeve.
  • a person skilled in the art will be able to adapt the number, nature and thickness of the constituent layers to suit the capacities of the machine and the desired production rate.
  • the device for packaging carbon dioxide snow comprises means for injecting inerting gas in the region of the carbon dioxide generator. This makes it possible to continuously flush the carbon dioxide snow generator in order to prevent air or carbon dioxide entraining carbon dioxide snow from being sucked back into the carbon dioxide snow generator when the supply of liquid carbon dioxide is interrupted and in order to allow improved dropping of the carbon dioxide snow into the shaped plastic film.
  • the means for injecting inerting gas comprise, for example, a gas feed nozzle arranged at the inlet of the carbon dioxide generator.
  • the inerting gas used can be any gas which is not reactive with respect to the carbon dioxide snow. If the carbon dioxide snow is intended for preserving food products, this gas will be compatible with such a use.
  • the preferred gas is carbon dioxide. However, preference is given above all to using a substantially anhydrous inerting gas (dew point of around ⁇ 40° C.) in order, given the temperature of the carbon dioxide snow, to prevent any traces of water from icing to form water ice.
  • the device for packaging carbon dioxide snow can comprise means for injecting a fluid having a temperature below the dew point temperature of air into contact with and inside the plastic film container.
  • such means can consist of an injection rod which is arranged in the space formed between the carbon dioxide snow generator and the shaper and whose free end is oriented toward the plastic film released by the shaper.
  • Any food-quality fluid is suitable for this purpose.
  • liquid carbon dioxide is preferred.
  • the means for injecting liquid carbon dioxide is connected to the source of liquid carbon dioxide which is used to generate carbon dioxide snow.
  • a valve generally a solenoid valve, is inserted between the injection rod and the source of liquid carbon dioxide so as to start and stop the supply of liquid carbon dioxide.
  • a valve generally a solenoid valve, is also inserted between the carbon dioxide snow generator and the source of liquid carbon dioxide so as to start and stop the supply of carbon dioxide snow.
  • the device for packaging carbon dioxide snow comprises at least one means for removing the gaseous carbon dioxide.
  • This means can consist of the space formed between the outer wall of the carbon dioxide snow generator and the inner wall of the shaping sleeve.
  • the removal means is connected at its top to a containment box, which will be connected, on the one hand, to an adjustable “hot” air inlet for heating this carbon dioxide gas, which is at a temperature of around ⁇ 80° C., and on the other hand to a line which is itself connected to a vacuum system used to suck in this toxic mixture.
  • the means for dispensing, shaping and moving the plastic film are those conventionally employed in known packaging devices. Generally, these means consist in continuously dispensing a strip of plastic film, in shaping it into a tube by winding it around a preshaping sleeve, in sealing the two edges of the tube which meet, and in sliding the tube obtained downstream of the preshaping sleeve.
  • the means for sealing the plastic film once said film has been shaped, make it possible to close the tube by thermal welding and then to cut it at the welded film stage in order to obtain a bag.
  • the carbon dioxide snow generator is placed inside the shaping sleeve in such a way that the snow produced is directed into the bag being formed.
  • the means for dispensing and shaping the plastic film are positioned in such a way as to form a vertical bag whose opening is on the top side, and the carbon dioxide snow generator is oriented vertically in such a way that the carbon dioxide snow formed drops under gravity into the shaped plastic bag and in such a way that, once the latter has been sealed and cut, the bag containing the carbon dioxide snow also drops under gravity.
  • the plastic film is generally chosen from materials allowing evacuation of the gaseous carbon dioxide resulting from the sublimation of the carbon dioxide snow. This property can be achieved by the porosity of the plastic film.
  • the plastic film used is then microporous or has microperforations.
  • the plastic film can be chosen such that the perforations make it possible for the significant mass of expansion gas to escape and also for the fine crystals making up the carbon dioxide snow to be retained and contained.
  • the microperforations can be produced at the time of manufacturing the plastic film or during the method according to the invention, for example in a prior step of preparing the plastic film such as by passing the plastic film over perforating spikes.
  • the plastic film can be thermally welded.
  • the plastic film is microperforated polypropylene having a thickness of between 25 and 80 microns, preferably between 35 and 70 microns.
  • the thickness of the plastic film will be tailored to the quantity of carbon dioxide snow contained in a bag.
  • the number of perforations and their diameter will be tailored to suit the quantity of carbon dioxide snow contained and the desired rate of sublimation.
  • the device can also comprise at least one means for compacting the carbon dioxide snow in the plastic film container.
  • a means can consist of a tamper arranged on the lower part of the plastic film container. Said tamper can be actuated by a system of electromagnets or by an electropneumatic system.
  • the invention also relates to a method of packaging carbon dioxide snow in a plastic film container, wherein:
  • the injection of an inerting gas into the carbon dioxide snow generator makes it possible to continuously flush the carbon dioxide snow generator in order to prevent air or carbon dioxide from being sucked back into the carbon dioxide snow generator when the vaporization is stopped and to allow improved dropping of the carbon dioxide snow into the shaped plastic film.
  • any gas which does not react with the carbon dioxide snow is suitable for this purpose.
  • the gas used will be of food quality.
  • carbon dioxide is used.
  • the injection of carbon dioxide into the carbon dioxide snow generator takes place in a pulsed manner, that is to say that the vaporization is stopped as soon as a sufficient quantity of liquid carbon dioxide has been injected to give the desired quantity of carbon dioxide snow.
  • the method can additionally comprise a step of forming a plastic film container. This step allows the continuous formation of an open plastic film container. The carbon dioxide snow formed is then introduced into said container through its opening and then the opening is closed, for example, by heat sealing.
  • the plastic film container is formed using a packaging device comprising a preferably cylindrical shaping sleeve which is arranged vertically and whose operation has been described above in connection with the device.
  • the carbon dioxide snow formed fills the container under gravity and then, when the desired quantity of carbon dioxide snow has been introduced, the upper part of the container is sealed.
  • a continuous additional step of maintaining the temperature of the shaping sleeve is added.
  • the temperature of the shaping sleeve is maintained at a temperature of at least ⁇ 10° C., preferably at least 0° C., and more preferably still at least 10° C.
  • the method according to the invention can also comprise a step of continuously removing the gaseous carbon dioxide formed during the step of carbon dioxide snow formation.
  • the gaseous carbon dioxide removed along the carbon dioxide snow generator is generally discharged away from the premises in which the carbon dioxide snow is packaged, for safety reasons.
  • Another optional step of the method according to the invention comprises injecting a fluid having a temperature below the dew point temperature of air into contact with and inside the plastic film container prior to injecting liquid carbon dioxide.
  • the fluid having a temperature below the dew point temperature of air is liquid carbon dioxide.
  • the step of carbon dioxide snow formation or prior to this step, it is sufficient to inject a small quantity of liquid carbon dioxide so as to cool the inner wall of the plastic film container to a temperature below the dew point temperature of air.
  • a few grams of liquid carbon dioxide at ⁇ 80° C. or a squirt of the latter from a capillary is sufficient.
  • This step can be carried out at each new step of carbon dioxide snow formation or else only when starting up the device after a prolonged shutdown.
  • the method can comprise a compacting step which makes it possible to compact the carbon dioxide snow in the container in order to facilitate sealing of the upper part of the container.
  • the method is a continuous carbon dioxide snow packaging method.
  • the liquid carbon dioxide which is injected inside and into contact with the plastic film container and that which is injected into the carbon dioxide snow generator come from the same source of liquid carbon dioxide.
  • the carbon dioxide source can be a cylinder of pressurized carbon dioxide in the liquid state, but it is preferably rather a source of refrigerated low-pressure liquid carbon dioxide since this type of source leads to better efficiency in terms of carbon dioxide snow generation.
  • the conditions under which the source of liquid carbon dioxide is stored can, for example, be a temperature of ⁇ 20° C. and a pressure of approximately 20 bar, or even less.
  • FIGS. 1 to 5 illustrate the device and the method according to the invention.
  • the complete system ( 1 ) is represented in FIG. 1 .
