According to the method, grape residues are collected, which are grape stalks, grape marc, seeds or grape skins and pulp. We also collect residues of the RV vine which can be vine shoots or vines. These different residues are treated separately. And within each category, the nature and characteristics of the products can vary greatly.
Selon la figure 1, le procédé consiste à collecter (1) les résidus de raisins RR ou les résidus de vigne RV. Puis, à soumettre ces résidus RR ou RV à un séchage (2) jusqu’à une teneur en humidité de 10%. According to Figure 1, the method consists of collecting (1) the grape residues RR or the vine residues RV. Then, subjecting these RR or RV residues to drying (2) to a moisture content of 10%.
Les résidus séchés RRS ou RVS sont ensuite broyés, puis tamisés avec des tamis de différentes granulométrie pour récupérer différentes fractions allant de 50μm à quelques millimètres. The dried RRS or RVS residues are then ground, then sieved with sieves of different grain sizes to recover different fractions ranging from 50 μm to a few millimeters.
Les produits broyés sont des microfibres MF et de la farine FF.
Les caractéristiques des microfibres et de la farine étant différentes, il est prévu, selon l’invention, de trier les résidus broyés RB en une phase de triage 4 pour séparer les microfibres MF et la farine FF. Les microfibres séparées se caractérisent par des longueurs de fibres allant de 250 pm à 1-2 mm. The ground products are MF microfibers and FF flour. Since the characteristics of the microfibers and of the flour are different, provision is made, according to the invention, to sort the ground residues RB in a sorting phase 4 to separate the microfibers MF and the flour FF. Separated microfibers are characterized by fiber lengths ranging from 250 µm to 1-2 mm.
La farine FF se caractérise par une granulométrie inférieure à 250 pm.FF flour is characterized by a particle size of less than 250 µm.
Les microfibres MF et la farine FF séparées sont stockées de façon intermédiaire 4a, 4b pour être ensuite utilisées selon des proportions précises, variables selon la nature de la matière première à obtenir. The separated MF microfibers and flour FF are stored intermediately 4a, 4b to then be used according to precise proportions, which vary according to the nature of the raw material to be obtained.
Cette séparation par le tamisage 4 est aussi nécessaire parce que la composition des résidus est variable et les résidus d’une même collecte, donc d’une même origine, peuvent avoir une composition non homogène qui, par broyage (3) donnent une composition de microfibres MF et de farine FF qui peut varier. This separation by sieving 4 is also necessary because the composition of the residues is variable and the residues from the same collection, therefore from the same origin, can have an inhomogeneous composition which, by grinding (3) gives a composition of MF microfibers and FF flour which may vary.
La séparation des deux composants par tamisage 4 permet de constituer une réserve 4a de microfibres MF et une réserve 4b de farine FF.The separation of the two components by sieving 4 makes it possible to constitute a reserve 4a of microfibers MF and a reserve 4b of flour FF.
L’étape suivante est la phase de mélange 6 selon des proportions pondérales de microfibres et de farine FF selon la matière première à obtenir.The next step is the mixing phase 6 according to weight proportions of microfibers and FF flour according to the raw material to be obtained.
La composition de la matière issue de résidus de raisins pour la fabrication d’objets comprend selon l’invention : The composition of the material from grape residues for the manufacture of objects comprises according to the invention:
- une proportion pondérale de microfibres comprise entre 0 et 50% de préférence entre 2 et 40% et de manière encore plus préférentielle entre 5 et 30%, - a weight proportion of microfibers between 0 and 50%, preferably between 2 and 40% and even more preferably between 5 and 30%,
- une proportion pondérale de farine comprise entre 0 et 50%, de préférence entre 2 et 40% et de manière encore plus préférentielle entre 5 et 30%, - a proportion by weight of flour between 0 and 50%, preferably between 2 and 40% and even more preferably between 5 and 30%,
- une proportion de résine comprise entre 50 et 98%, - a proportion of resin between 50 and 98%,
Une proportion de colorant comprise entre 0 et 10%, de préférence entre 0 et 5% et de manière encore plus préférentielle entre 0 et 3%, A proportion of dye between 0 and 10%, preferably between 0 and 5% and even more preferably between 0 and 3%,
- une proportion d’adjuvant (pouvant être un démoulant, ou un plastifiant) comprise entre 0 et 30%, de préférence entre 0 et 20% et de manière encore plus préférentielle entre 0 et 10% - a proportion of adjuvant (which may be a mold release or a plasticizer) of between 0 and 30%, preferably between 0 and 20% and even more preferably between 0 and 10%
La résine RES, ajoutée est en particulier une résine liée ou sourcée telle que des résines polyesters comme les acides polylactiques, les polyté- réphtalate d’éthylène, de butylène par exemple, des résines polypropy- lènes ou bien des résines polystyrènes, des résines polyéthylènes ou encore une résine combinée de ces deux ou trois composants.
La résine est ajoutée dans des proportions pondérales allant de 50 à 98% si la proportion de fibres dans le mélange est comprise entre 2 et 50%. The added RES resin is in particular a bonded or sourced resin such as polyester resins such as polylactic acids, polyethylene terephthalate, butylene for example, polypropylene resins or else polystyrene resins, polyethylene resins or even a combined resin of these two or three components. The resin is added in weight proportions ranging from 50 to 98% if the proportion of fibers in the mixture is between 2 and 50%.
Le mélange obtenu MG ou MF, selon la destination, alimente une phase de mise en forme de granulés 6A ou une mise en forme 6b de filaments.The mixture obtained MG or MF, depending on the destination, feeds a granule shaping phase 6A or a filament shaping phase 6b.
Les granulés GR sont destinés à l’injection 7 pour obtenir les objets 9. Les filaments FI sont destinés à l’impression 3D pour obtenir d’autres types d’objets 10 car les granulés sont de façon préférentielle utilisés pour l’injection alors que les filaments conviennent mieux pour l’impression en 3D. GR granules are intended for injection 7 to obtain objects 9. FI filaments are intended for 3D printing to obtain other types of objects 10 because granules are preferentially used for injection whereas filaments are more suitable for 3D printing.
La figure 2 montre le détail du procédé d’obtention de résidus RR à partir de marc épuisé, humide MEH collecte (20) Figure 2 shows the detail of the process for obtaining RR residues from spent pomace, wet MEH collection (20)
Le marc de raisin est distillé dans des colonnes de distillation pour séparer les anthocyanes et l’alcool. Le résidu de cette distillation est un marc épuisé, humide MEH Grape marc is distilled in distillation columns to separate anthocyanins and alcohol. The residue from this distillation is spent pomace, moist MEH
Ce marc MEH est trié (21) pour séparer, d’une part, les pépins PE et les peaux PX et les pulpes PU, et obtenir, d’autre part, le marc épuisé, épé- piné et dépulpé MEED comme résidu RR. This marc MEH is sorted (21) to separate, on the one hand, the pips PE and the skins PX and the pulps PU, and to obtain, on the other hand, the exhausted, deseeded and depulped marc MEED as residue RR.
Les pépins PE, les peaux PX et les pulpes PU sont séchés 22 puis triés 23 pour séparer, d’une part, les pulpes PUS et peaux PX et, d’autre part, les pépins PES. The PE seeds, the PX skins and the PU pulps are dried 22 then sorted 23 to separate, on the one hand, the PUS pulps and PX skins and, on the other hand, the PES seeds.
Ces produits PUS, PES, MEED sont utilisés comme résidus RR dans le procédé de fabrication selon la figure 1. These PUS, PES, MEED products are used as RR residues in the manufacturing process according to Figure 1.
De façon plus détaillée, les objets obtenus à partir de la matière première constituée par les granulés GR ou les filaments FI, par injection ou par impression 3D sont, par exemple, des bouchons, des têtes de bouchon ou des capsules. In more detail, the objects obtained from the raw material constituted by the granules GR or the filaments FI, by injection or by 3D printing are, for example, stoppers, stopper heads or capsules.
Par injection 7 on peut fabriquer un bouchon cylindrique procédant par extrusion en continu et découpe à la longueur voulue. By injection 7 it is possible to manufacture a cylindrical stopper proceeding by continuous extrusion and cutting to the desired length.
On peut également fabriquer des têtes de bouchon pour spiritueux. A cette tête on fixe des bouchons traditionnels en liège, par exemple, par collage.
On peut également et à la place des bouchons en liège, fixer des bouchons fabriqués à partir de matières premières renouvelables comme des polymères pouvant être issus de la canne à sucre. Cork heads for spirits can also be made. To this head are fixed traditional cork stoppers, for example, by gluing. It is also possible and instead of cork stoppers, to fix stoppers made from renewable raw materials such as polymers that can be derived from sugar cane.
On peut également fabriquer avec cette matière première, des bouchons pour spiritueux comprenant à la fois la tête de bouchon et le corps de bouchon fabriqués par injection. Dans ce cas, il n’y a pas de collage de la tête au corps de bouchon. It is also possible to manufacture with this raw material corks for spirits comprising both the cork head and the cork body manufactured by injection. In this case, there is no sticking of the head to the cap body.
Par injection, on peut également fabriquer des bouchons à vis pour gourde surmontés, par exemple, d’un anneau pour une meilleure prise en main ou encore comprenant un goulot pour favoriser la prise de liquide. By injection, it is also possible to manufacture screw caps for canteens surmounted, for example, by a ring for a better grip or even comprising a neck to promote the intake of liquid.
Ces objets ont la particularité de pouvoir être biosourcés. Par soufflage, on peut également fabriquer des contenants pour conditionner des boissons, des produits cosmétiques, des parfums... These objects have the particularity of being able to be biosourced. By blowing, it is also possible to manufacture containers for packaging drinks, cosmetics, perfumes, etc.
Selon la combinaison polymère / résine utilisée, les objets pourront être compostables dans un composteur industriel ou biodégradables dans des conditions spécifiques et suivant la granulométrie, les composés se dégraderont plus ou moins lentement.
Depending on the polymer / resin combination used, the objects may be compostable in an industrial composter or biodegradable under specific conditions and depending on the particle size, the compounds will degrade more or less slowly.
