Dispositif pour le contrôle de la maturation des végétaux et son utilisation pour leur conditionnement
L'invention concerne un dispositif pour le contrôle de la maturation des végétaux et son utilisation pour leur conditionnement. Device for controlling the maturation of plants and its use for their conditioning
The invention relates to a device for controlling the maturation of plants and its use for their conditioning.
Les végétaux tels que les fruits et légumes pouvant être produits loin de leur lieu de consommation, on a déjà tenté à mainte reprises de résoudre le problème du contrôle de leur maturation pendant leur transport, qui est parfois long. Since plants such as fruit and vegetables can be produced far from their place of consumption, attempts have been made on numerous occasions to solve the problem of controlling their ripening during their transport, which is sometimes long.
Il est connu (US 4079152) de disposer les fruits et légumes dans une enceinte fermée constituée au moins en partie d'un film perméable aux gaz. Pour contrôler la vitesse de maturation des fruits et légumes, on dispose dans l'enceinte une enveloppe, perméable aux gaz mais imperméable aux liquides, contenant du chlorure de calcium et de l'hydroxyde de calcium. Le chlorure de calcium absorbe l'humidité tandis que l'hydroxyde de calcium absorbe le dioxyde de carbone produit par la maturation des fruits et légumes. It is known (US 4079152) to arrange the fruits and vegetables in a closed enclosure constituted at least in part by a film permeable to gases. To control the ripening speed of fruits and vegetables, an enclosure is placed in the enclosure, permeable to gases but impermeable to liquids, containing calcium chloride and calcium hydroxide. Calcium chloride absorbs moisture while calcium hydroxide absorbs carbon dioxide produced by the ripening of fruits and vegetables.
Ce dispositif connu de contrôle de la maturation des fruits et légumes présente cependant le désavantage d'être inactif vis à vis de l'éthylène produit par les végétaux durant leur maturation. Or cet éthylène, notamment en s'accumulant dans le récipient fermé contenant les végétaux transportés, accélère leur maturation et les endommage. This known device for controlling the ripening of fruits and vegetables has the disadvantage of being inactive with respect to the ethylene produced by plants during their ripening. However, this ethylene, in particular by accumulating in the closed container containing the transported plants, accelerates their maturation and damages them.
L'invention vise à résoudre cet inconvénient du dispositif connu en fournissant un dispositif comprenant des réactifs dont l'action combinée permet un contrôle efficace de la maturation des végétaux. The invention aims to solve this drawback of the known device by providing a device comprising reagents whose combined action allows effective control of the maturation of plants.
En conséquence, l'invention concerne un dispositif destiné au contrôle de la maturation de végétaux, comprenant du chlorure de calcium et de l'hydroxyde de calcium disposés dans une enveloppe perméable aux gaz et sensiblement imperméable aux liquides, qui se caractérise en ce que la dite enveloppe contient en outre du permanganate de potassium. Consequently, the invention relates to a device intended for controlling the ripening of plants, comprising calcium chloride and calcium hydroxide placed in a gas permeable and substantially impermeable to liquids envelope, which is characterized in that the said envelope also contains potassium permanganate.
L'enveloppe du dispositif conforme à l'invention peut être de forme quelconque, par exemple : circulaire, rectangulaire, ovale. Afin d'augmenter la surface d'échange avec les gaz émis par la maturation de végétaux, l'enveloppe est de préférence aplatie, c'est à dire qu'une de ses dimensions est nettement inférieure aux deux autres. Les dimensions de l'enveloppe dépendent des The envelope of the device according to the invention can be of any shape, for example: circular, rectangular, oval. In order to increase the exchange surface with the gases emitted by the maturation of plants, the envelope is preferably flattened, that is to say that one of its dimensions is clearly smaller than the other two. The dimensions of the envelope depend on
<Desc/Clms Page number 2><Desc / Clms Page number 2>
conditions particulières de son utilisation. Sa surface extérieure peut varier de quelques dizaines à plusieurs milliers de centimètres carrés. special conditions for its use. Its external surface can vary from a few tens to several thousand square centimeters.
Lorsque les trois réactifs (chlorure de calcium, hydroxyde de calcium, permanganate de potassium) se trouvent dans l'enveloppe, celle ci est fermée par tout moyen adéquat tel que accrochage mécanique, collage, scellage, soudure. Il faut veiller à ce que la fermeture soit étanche aux liquides. When the three reagents (calcium chloride, calcium hydroxide, potassium permanganate) are in the envelope, it is closed by any suitable means such as mechanical attachment, bonding, sealing, welding. Make sure that the closure is liquid tight.
Les propriétés de perméabilité aux gaz et imperméabilité aux liquides de l'enveloppe sont un aspect important de l'invention. Les gaz (CO2, vapeur d'eau, éthylène) produits par les végétaux doivent pouvoir pénétrer dans l'enveloppe, afin d'y réagir avec les produits (CaCl2, Ca (OH) 2, KMnO4) qui s'y trouvent. En revanche les solutions liquides qui se forment dans l'enveloppe suite à ces réactions doivent rester sensiblement confinées dans l'enveloppe afin de ne pas se répandre sur les végétaux que l'on désire protéger. L'enveloppe doit donc être sensiblement imperméable aux liquides. The gas permeability and liquid impermeability properties of the envelope are an important aspect of the invention. The gases (CO2, water vapor, ethylene) produced by plants must be able to penetrate the envelope, in order to react with the products (CaCl2, Ca (OH) 2, KMnO4) found there. On the other hand, the liquid solutions which form in the envelope following these reactions must remain substantially confined in the envelope so as not to spread on the plants which it is desired to protect. The envelope must therefore be substantially impermeable to liquids.
Dans un mode d'exécution préféré du dispositif selon l'invention, l'enveloppe est en polymère thermoplastique. La grande variété des polymères thermoplastiques existants et la diversité de leurs mises en oeuvre, telles que la biorientation, permet en effet d'obtenir les propriétés de perméabilité sélective recherchées pour l'enveloppe. In a preferred embodiment of the device according to the invention, the envelope is made of thermoplastic polymer. The wide variety of existing thermoplastic polymers and the diversity of their applications, such as biorientation, makes it possible to obtain the selective permeability properties desired for the envelope.
Dans une variante avantageuse de ce mode d'exécution, la matière thermoplastique est du polyéthylène haute densité fibreux. On entend par fibreux que la matière est en partie constituée de fibres de polyéthylène. Ces fibres ont d'excellentes propriétés mécaniques. Un exemple de telle matière thermoplastique est le polyéthylène haute densité fibreux TYVEKE commercialisé par du Pont de Nemours. In an advantageous variant of this embodiment, the thermoplastic material is fibrous high density polyethylene. By fibrous is meant that the material is partly made of polyethylene fibers. These fibers have excellent mechanical properties. An example of such a thermoplastic material is the high density fibrous polyethylene TYVEKE sold by du Pont de Nemours.
Le chlorure de calcium, l'hydroxyde de calcium et le permanganate de potassium sont de préférence mis en oeuvre à l'état solide dans l'enveloppe, par exemple à l'état de granules ou d'une poudre. The calcium chloride, calcium hydroxide and potassium permanganate are preferably used in the solid state in the envelope, for example in the form of granules or of a powder.
Les quantités de chlorure de calcium, d'hydroxyde de calcium et de permanganate de potassium à mettre en oeuvre dans le dispositif conforme à l'invention dépendent du type et de la quantité de végétaux dont la maturation doit être contrôlée par le dispositif. Il dépend également du niveau de maturation optimum désiré : une quantité importante de réactifs ralentira celle-ci davantage qu'une plus faible quantité. Lorsque le végétal est cueilli à un stade précoce de maturation, une certaine maturation pendant le transport peut être désirée. The amounts of calcium chloride, calcium hydroxide and potassium permanganate to be used in the device according to the invention depend on the type and amount of plants whose maturation must be controlled by the device. It also depends on the optimum level of maturation desired: a large quantity of reagents will slow it down more than a lower quantity. When the plant is picked at an early stage of ripening, some ripening during transport may be desired.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Il est avantageux que le dispositif selon l'invention comprenne, par kg de végétaux, plus de 0, 5 g de chlorure de calcium. Il est également avantageux qu'il comprenne plus de 1,5 g d'hydroxyde de calcium. De manière avantageuse il comprend plus de 0,05 g de permanganate de potassium. Il est toutefois préférable que les quantités de chlorure de calcium n'excèdent pas 30g par kg de végétaux. Il est également préférable que les quantités d'hydroxyde de calcium n'excèdent pas 60 g par kg de végétaux. Les quantités de permanganate n'excèdent quant à elles de préférence pas 1g par kg de végétaux. It is advantageous that the device according to the invention comprises, per kg of plants, more than 0.5 g of calcium chloride. It is also advantageous that it comprises more than 1.5 g of calcium hydroxide. Advantageously, it comprises more than 0.05 g of potassium permanganate. It is however preferable that the amounts of calcium chloride do not exceed 30g per kg of plants. It is also preferable that the amounts of calcium hydroxide do not exceed 60 g per kg of plants. The amounts of permanganate preferably do not exceed 1 g per kg of plants.
Dans une forme de réalisation particulièrement avantageuse du dispositif selon l'invention, celui-ci comprend, par kg de végétaux, de 1 à 15 g de chlorure de calcium, de 3 à 30 g d'hydroxyde de calcium, et de 0,15 à 0,5 g de permanganate de potassium. In a particularly advantageous embodiment of the device according to the invention, it comprises, per kg of plants, from 1 to 15 g of calcium chloride, from 3 to 30 g of calcium hydroxide, and from 0.15 0.5 g of potassium permanganate.
Dans une autre forme de réalisation avantageuse du dispositif selon l'invention, l'enveloppe est divisée en deux compartiments, le chlorure de calcium et l'hydroxyde de calcium étant disposés ensemble dans un des
compartiments, tandis que le permanganate de potassium est disposé dans l'autre tD compartiment. In another advantageous embodiment of the device according to the invention, the envelope is divided into two compartments, the calcium chloride and the calcium hydroxide being arranged together in one of the
compartments, while potassium permanganate is arranged in the other tD compartment.
L'invention s'applique spécialement aux fruits et aux légumes. The invention applies especially to fruits and vegetables.
L'invention concerne également une utilisation du dispositif conforme à l'invention décrite ci-dessus, dans une enceinte de conditionnement fermée pour végétaux constituée au moins en partie d'un film semi-perméable. Cette enceinte de conditionnement fermée est par exemple une caisse dans laquelle les fruits ou légumes ont été introduits. Le dispositif conforme à l'invention est également placé dans la caisse, par exemple au dessus des fruits ou légumes. Une face de la caisse, qui a servi à la remplir, est ensuite fermée par un film semi-perméable. The invention also relates to a use of the device according to the invention described above, in a closed packaging enclosure for plants consisting at least in part of a semi-permeable film. This closed packaging enclosure is for example a box into which the fruits or vegetables have been introduced. The device according to the invention is also placed in the box, for example above the fruit or vegetables. One side of the box, which was used to fill it, is then closed with a semi-permeable film.
Par film semi-perméable on entend un film dont la perméabilité au CO2 est nettement supérieure à la perméabilité à l'oxygène et qui est sensiblement imperméable à l'eau et à la vapeur d'eau. By semi-permeable film is meant a film whose permeability to CO2 is much higher than the permeability to oxygen and which is substantially impermeable to water and water vapor.
Dans une variante préférée de cette utilisation, le matériau de base du film semi-perméable est sélectionné parmi le polyéthylène basse densité, le polypropylène, le polychlorure de vinylidène ou le polychlorure de vinyle. In a preferred variant of this use, the base material of the semi-permeable film is selected from low density polyethylene, polypropylene, polyvinylidene chloride or polyvinyl chloride.
Le dispositif selon l'invention présente l'avantage de contrôler la maturation des végétaux et de permettre leur livraison, après leur transport, dans un état optimum pour leur vente et leur consommation. The device according to the invention has the advantage of controlling the maturation of the plants and of allowing their delivery, after their transport, in an optimum state for their sale and consumption.
Des particularités et détails de l'invention vont ressortir de la description suivante de la figure annexée. Special features and details of the invention will emerge from the following description of the appended figure.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
La figure représente une enceinte de conditionnement de légumes, désignée dans son ensemble par la référence 6. The figure represents an enclosure for packaging vegetables, generally designated by the reference 6.
Elle comprend une caisse 1 fermée à sa face supérieure par un film semiperméable 2 en polyéthylène basse densité. Dans la caisse 1 sont disposés des légumes 3 et un dispositif conforme à l'invention, désigné dans son ensemble par la référence 4. Le dispositif 4 comprend du chlorure de calcium, de l'hydroxyde de calcium et du permanganate de potassium, non représentés, disposés dans une enveloppe 5. It comprises a box 1 closed at its upper face by a semipermeable film 2 made of low density polyethylene. In the box 1 are arranged vegetables 3 and a device according to the invention, generally designated by the reference 4. The device 4 comprises calcium chloride, calcium hydroxide and potassium permanganate, not shown , arranged in an envelope 5.
La perméabilité du film 2 à l'oxygène est nettement inférieure à sa perméabilité au CO2. Il est en outre sensiblement imperméable à l'eau. De ce fait, la teneur en oxygène dans l'enceinte 5 diminue au cours du temps, puisqu'il est consommé par la respiration des légumes 3. Il en résulte que la respiration des légumes 3 est ralentie. Le dioxyde de carbone et l'éthylène, produits par la respiration des légumes, qui n'ont pu s'échapper de l'enceinte par le film 2 sont absorbés dans le dispositif 4, de même que la vapeur d'eau présente dans l'enceinte 6. The permeability of the film 2 to oxygen is much lower than its permeability to CO2. It is also substantially waterproof. Therefore, the oxygen content in the enclosure 5 decreases over time, since it is consumed by the respiration of the vegetables 3. As a result, the respiration of the vegetables 3 is slowed down. Carbon dioxide and ethylene, produced by the respiration of the vegetables, which could not escape from the enclosure by the film 2 are absorbed in the device 4, as is the water vapor present in the pregnant 6.
Les exemples suivants servent à illustrer l'invention. The following examples serve to illustrate the invention.

Eight kilos of tomatoes, harvested between 8 and 12 am, are placed from the harvest in a polypropylene box, dimensions 49 x 35 x 20 cm.
La face supérieure (dimensions 49 x 35 cm) de la boîte est fermée au moyen d'un film en polyéthylène basse densité (LDPE) ayant une épaisseur de 25 microns. Après 7 jours de conservation à température ambiante (20OC), les fruits ont présenté des premiers signes de pourriture. The upper face (dimensions 49 x 35 cm) of the box is closed by means of a film of low density polyethylene (LDPE) having a thickness of 25 microns. After 7 days of storage at room temperature (20OC), the fruits showed the first signs of decay.
Exemple 2 (non conforme à l'invention)
On a opéré comme à l'exemple 1, excepté qu'une enveloppe en polyéthylène haute densité TYVEK (R), de 15 x 12 cm, contenant 100g d'un mélange constitué de 35g de CaCL et 65g de Ca (OH) 2 et ayant été fermée par scellage à chaud a été placée dans la caisse, au dessus des tomates. Après 12 jours de conservation à 20OC, les tomates n'ont témoigné d'aucun signe de pourriture mais ont présenté par contre un ramollissement qui réduit leur attrait commercial. Example 2 (not in accordance with the invention)
The procedure was as in Example 1, except that a TYVEK (R) high density polyethylene envelope, of 15 × 12 cm, containing 100 g of a mixture consisting of 35 g of CaCL and 65 g of Ca (OH) 2 and having been closed by heat sealing was placed in the box, above the tomatoes. After 12 days of storage at 20OC, the tomatoes did not show any sign of decay, but did show softening which reduced their commercial appeal.
Exemple 3 (conforme à l'invention)
On a opéré comme à l'exemple 2, excepté qu'on a utilisé une enveloppe, de dimensions 20 x 12cm, divisée en deux compartiments, le premier contenant 98g d'un mélange constitué de 34g de CaCl2 et 64g de Ca (OH) 2 et le deuxième Example 3 (according to the invention)
The procedure was as in Example 2, except that an envelope, of dimensions 20 × 12 cm, divided into two compartments was used, the first containing 98 g of a mixture consisting of 34 g of CaCl 2 and 64 g of Ca (OH) 2 and the second
