  • the second step of the process is submerging 24, Figure 2, the sealed vial 26 in water 28.
  • the stem 12 of the flower 14 is cut, preferably under water 28 and then inserted through the pierceable membrane 123 (or toroidal ring 124) of the submerged vial 26 and into the mass of absorbent material 30. As this is done, the membrane 123, or toroidal ring 124, forms a tight seal about the stem 12 of the flower 14.
  • the step of cutting the stem under water to avoid the introduction of air (a "bubble") into the stem capillaries is known in the art.
  • the third step of the process is assembling several of the flowers 14 and their associated vials 26 into a bouquet 32, Figure 3, which is then placed in a plastic tray 34 to form package 36 for packaging.

  • a MAP machine which is used to package meat, fish, and other products is basically similar to that which is used in the present invention, although it has been modified for the present process.
  • the fourth step of the process is placing the package 36, Figure 4, on a conveyer 38 which leads into and through the MAP machine 40. It first passes through a gas treatment hood 42 which can either be an ozone treatment hood or a nitration hood or a combination of the two. If ozone is used it serves to sterilize the flowers against microorganisms. From here, the package moves to the interior of the MAP machine itself.

  • the fifth step of the process is conveying the package 36 to the vacuum chamber 44, Figure 5, of the MAP machine 40, which is maintained at a vacuum within a range which is suitable for the type of flower being packaged. In the case of roses, about 3.5 inches Hg is suitable.

While there is some knowledge in the industry that these gases can help enhance the characteristics of the flower (and the use of N 2 itself is well known in MAP packaging) , I have developed some proprietary ratios which are specifically adapted to particular varieties of flowers.
  • the sixth step of the process is conveying the tray containing the flowers 46 from the vacuum chamber through the packaging section 64 of the MAP machine 40.
  • these sections, vacuum chamber 44 and packaging section 64 may be continuous.
  • the packaging section 64 is maintained under vacuum and with the same N 2 /He/Ar atmosphere 62.
  • a plastic seal 66 is pressed onto the tray 34 by a die 68. This part of the process, apart from the mixture of gases, is generally conventional in MAP machines. Following this, the sealed package 70 continues on the conveyer and exits the packaging section 64.

  • the plastic seal 66 maintains the vacuum 72 inside the package.
  • the N 2 atmosphere 74 continues to stabilize the plant against deterioration, and the He/Ar mixture 74 continues to intensify the colors of the flowers.
  • the vacuum 72 "pulls" the liquid preservative and rehydrator 16 up through the stems and out through the pores of the flowers 76 as the liquid is released in a controlled manner from the cellulosic fibers of the absorbent material 18.
  • the invention uses a cellulosic material to achieve a controlled release 76 of the liquid preservative/rehydrator and aluminum and/or silver thiosulfate (STS) , and optionally color enhancers (such as carotene) 16 under vacuum 72 so that these are drawn upwardly through the flower while it is being stored in the packaging 70 and also the long term presence of the He/Ar mixture in the packaging to enhance the coloration of the flowers.

  • While the present invention relates to a process for packaging roses, other flowers or other "botanicals" (e.g., cedar fronds, ferns) can also be preserved in a fresh state for an extended period. While the process describes packaging of multiple flowers one skilled in the art would know that single flowers as well as bouquets of the same type of flower or multiple types of flowers can also be packaged using this process.
  • other flowers or other "botanicals” e.g., cedar fronds, ferns
  • the vacuum chamber in most cases will be kept between 3 1/2 to 10 1/2 inches of mercury. A vacuum below 3 1/2 inches of mercury does not allow for a good seal. Vacuums above 10 1/2 inches of mercury tend to destroy the cellular structure of the flower or plant. In the case of roses the maximum vacuum is about 4 1/2 to 5 inches of mercury. Cedar ferns can withstand vacuums of up to 10 1/2 inches of mercury.
  • the pH of the liquid packed with the flowers is important to their extended preservation. Additives to the vial should be in the pH range -6.0 to 6.0.
  • a proper blend of nitrogen, helium and argon which are ion balanced is optimal, it is noted that one could achieve good results by using just nitrogen, or a mixture of nitrogen and helium or nitrogen and argon.
  • one can achieve the proper blend of nitrogen, helium and argon by providing a blended gas control apparatus block diagrammed in Figure 8.
  • This apparatus consists of a helium tank 78, a nitrogen tank 80 and an argon tank 82 which are discretely connected to a helium isolator valve 84, a nitrogen isolator valve 86 and a argon isolator valve 88.
  • Each isolator valve is connected to a ulti-valve electronic controller and system controls 90 which regulates the flow of gas from each separate tank. Gases from each tank flow through their respective isolator valves into a mixing or blending manifold 92. The gases are combined in the mixing manifold 92.
  • Isolator valves 120, 122 are regulated by the multi-valve electronic controller and system controls 90. Before any gases can be introduced into one of the two storage tanks 110,
  • Vacuum pump 118 is connected to two isolated valves 116, 114 which are connected to the multi-valve electronic controller and system controls 90. Vacuum pump 118 is also operably associated with the multi-valve electronic controller 90.
  • Storage tanks 110, 112 are in communication with isolator valves 106, 108 which are in communication with a positive ion generator 94 to balance the ions of the gases. The positive ion generator then sends processed gas to the MAP machine .

  • This cabinet 98 can be mounted on a stainless steel frame 100 and is configured with controller switches 102 which are operably connected directly to the multi-valve electronic controller 90.
  • Cabinet 98 is configured with a blended gas output port 104.
  • the blended gas will be introduced into the vacuum chamber 44 through a single orifice (their would only be a single intake orifice for blended gas) . It is also possible to split the blended gas and have it enter both the vacuum chamber 44 and the packaging section 64.
  • the multi-valve electronic controller 90 opens one of the isolator vales 114, 116 and engages the vacuum pump 118 to evacuate one of the two storage tanks 110, 112. The multi-valve electronic controller 90 then closes that valve and opens one of the two isolator valves 120, 122 which allows the blended gas from mixing manifold 92 to flow into the selected storage tank. Once the storage tank is filled with blended gas the multi-valve electronic controller 90 closes off that tank and it is available to supply the proper gas mixture to the MAP machine while the electronic controller 90 regenerates the other tank. When used in this fashion, one charger tank will always be available while the system recharges the second tank.

Abstract

L'invention concerne un procédé et un appareil amélioré d'emballage de roses ou d'autres fleurs (ou d'autres 'articles botaniques', par exemple des fougères, des frondes de cèdre) permettant leur conservation dans un état frais pendant une durée prolongée. Une machine (40) d'emballage en atmosphère modifié (EAM) renferme la fleur de manière hermétique dans un récipient (34) sous vide, et un flacon (10) rattaché à la tige (12) de la fleur (14) contient une solution libérant un agent de conservation et de réhydratation (16) à partir d'un milieu absorbant, de sorte que lesdits agents s'écoulent dans la tige et vers l'extérieur à travers les pores de la fleur et de ses feuilles. Un environnement équilibré par des ions stabilise le pollen et la couleur tout en prolongeant la durée de conservation des fleurs coupées.
