Definitions

  • the present invention relates to a method and an apparatus for packaging products absorbing carbon dioxide, in particular perishable food products.
  • Said progressive absorption of carbon dioxide also causes a reduction of the carbon dioxide in the space surrounding the product, consequently producing a vacuum inside the package with the disadvantage of an inward collapse of the package if it is made of easily deformable material, as is usually the case for synthetic-material packaging containers.
  • the collapse of the package can cause the crushing of the products contained therein, deforming them and in some cases squeezing liquids out of them which make the appearance of said products extremely unappealing.
  • the absorption of carbon dioxide by the product furthermore modifies the percentages of gas, reducing the free carbon dioxide in the atmosphere inside the container and limiting the potential preservability of the product.
  • the deformation of the packaging container may furthermore cause the customer information, such as for example the date before which the product is to be eaten or other indications which are usually printed directly on the package or on sheets glued to the package or inserted therein, to become partially or totally unreadable.
  • the aim of the present invention is to solve the above described problems by providing a method for packaging products susceptible of absorbing carbon dioxide, in particular perishable food products, which avoids or at least considerably reduces the deformation of the package caused by vacuum after packaging.
  • an object of the invention is to provide a method which improves the preservability of products susceptible of absorbing carbon dioxide and respects the integrity of the product during packaging.
  • Another object of the invention is to provide a method which does not contaminate the product with health-damaging substances.
  • the method according to the invention comprises a first step wherein a product 1 or a plurality of products is inserted into a known containment package 2 made for example of synthetic material (figure 1), and a second step in which a preset amount of solid-phase carbon dioxide is introduced inside the package 2 (figure 2).
  • the package 2 is subsequently sealed, for example by heat-welding, glueing or by other known sealing methods, so as to isolate the inside of the package from the atmospheric environment.
  • the introduction of solid-phase carbon dioxide into the package 2 may naturally precede or follow the insertion of the product 1 or be simultaneous therewith.
  • the amount of carbon dioxide to be introduced in the package 2 is preset according to the amount of carbon dioxide which can be absorbed by the product after packaging, taking also into account the mechanical resistance of the package 2 and the final result to be obtained, for example so as to avoid the collapse of the package 2 even several days after packaging.
  • the amount of solid-phase carbon dioxide to be introduced in the package 2 may be easily determined on the basis of studies of the absorption in the various products, since it has been found that most of the products susceptible of absorbing carbon dioxide absorb most of the potentially absorbable carbon dioxide within a few hours after packaging, reaching a condition of equilibrium.
  • the solid-phase carbon dioxide is introduced into the package 2 in the form of cubes or tablets 3 of dry ice with a preset weight so as to meet the absorbability requirements of the product as described above.
  • the solid-phase carbon dioxide may also be introduced in the package 2 in the form of finely flaked dry ice ("carbonic snow").
  • the air present in the package 2 may be replaced completely with a controlled atmosphere constituted for example by a mixture of gas which predominantly contains carbon dioxide and nitrogen, sealing the package in an appropriate chamber 4 with a controlled atmosphere, as occurs in known packaging methods indeed termed "controlled-­atmosphere packaging methods".
  • the solid-phase carbon dioxide introduced in the package 2 slowly sublimates, pressurizing the interior of the package, while the product starts to absorb the gaseous-phase carbon dioxide, progressively decreasing the overpressure which has formed inside the package 2 (figure 4).
  • the pressure inside the package 2 stabilizes and the package 2 assumes a configuration which remains substantially unchanged for several days after packaging (figure 5).
  • the amount of solid-phase carbon dioxide introduced in the package 2 together with the amount of gas-­phase carbon dioxide possibly introduced when replacing the atmosphere inside the package 2 (if replacement is provided for) is slightly larger than the amount of carbon dioxide required to make the product reach the equilibrium condition, a mixture of gases, including carbon dioxide, with a slight overpressure or at ambient pressure is present inside the package 2 even several days after packaging, so as to avoid collapse even with packages which have an extremely low mechanical resistance or do not have an own form, such as soft bags.
  • both the step of introducing solid-phase carbon dioxide inside the package and the subsequent step of sealing the package 2 may occur in an atmospheric environment, since for a wide range of products correct preservation is in any case ensured by the modification of the atmosphere inside the package 2 caused by the sublimation of the solid-phase carbon dioxide.
  • an apparatus generally indicated by the reference numeral 10 in figure 6 may be used; said apparatus comprises a known packaging system with a conveyor element 11 on which the preformed packages 12 intended to contain the products 1 are placed. Said conveyor element 11 is movable along a path which traverses in sequence a station 5 for inserting the products 1 in the packages 12 and a sealing station 13 in which the packages 12 are closed by means of known devices.
  • a dispenser device 14 is arranged ahead of the sealing station 13 according to the direction of advancement of the conveyor element; said device introduces a preset amount of solid-phase carbon dioxide into the packages 12 and may be simply constituted, as illustrated, by nozzles which are fed by a known system and dispense a preset amount of finely flaked dry ice onto the product inside the package which is located in that moment below said nozzles.
  • the dispenser device may also be constituted by a means for dispensing dry ice tablets which are introduced, like the finely flaked dry ice, in the packages 12.
  • the sealing station 13 may be simply constituted by a known device which closes the open side of the packages 12 for example by heat-welding thereon a sheet of synthetic material 15.
  • the sealing station 13 may be placed inside a controlled-atmosphere chamber 16 which contains, in a known manner, a mixture of gases, for example a mixture of carbon dioxide and nitrogen, as in known controlled-atmosphere packaging devices.
  • a controlled-atmosphere chamber 16 which contains, in a known manner, a mixture of gases, for example a mixture of carbon dioxide and nitrogen, as in known controlled-atmosphere packaging devices.
  • a partial replacement of the atmosphere inside the packages 12 may be provided by arranging a dispenser 17 of inert gas, for example nitrogen, ahead of the solid-phase carbon dioxide dispensing device 14.
  • Said dispenser 17 may be simply constituted by a duct which feeds a jet of inert gas inside the packages 12.
  • a further advantage in view of the simple execution of the method according to the invention, is the fact that it can be used in both manual packaging methods and in automated packaging methods.
  • the method according to the invention has been conceived in particular for the packaging and preservation of perishable food products, it may in any case be used successfully also for any kind of product susceptible of absorbing carbon dioxide with similar problems regarding the integrity of the package and of the product after packaging.
