Abstract
Description
La présente invention concerne un procédé d'extraction du jus de betteraves, notamment par diffusion.The present invention relates to a process for extracting beet juice, in particular by diffusion.
Les procédés d'extraction du jus de betteraves, autrefois par pression et maintenant par diffusion, amènent, avec le jus contenant le saccharose, des impuretés et, en particulier, des matières pectiques qui, d'une part, abaissent la pureté, d'autre part, rendent les filtrations ultérieures plus difficiles.The processes of extraction of beet juice, formerly by pressure and now by diffusion, bring, with the juice containing sucrose, impurities and, in particular, pectic matters which, on the one hand, lower the purity, on the other hand, make subsequent filtration more difficult.
C'est la raison pour laquelle différents auteurs ont imaginé d'insolubiliser la matière pectique. A cet effet, ils ont proposé d'effectuer un traitement préalable des betteraves découpées en cossettes par de la chaux généralement sous forme de lait de chaux.This is the reason why different authors have imagined insolubilizing pectic matter. To this end, they have proposed carrying out a preliminary treatment of the beets cut into cossettes with lime generally in the form of milk of lime.
Les matières pectiques sont des polymères linéaires d'acide galacturonique. Une partie des groupements carboxyle est méthylée, une partie des groupements hydroxyle est acétylée. Lorsqu'on traite les matières pectiques à la chaux, on a deux réactions, d'abord une hydrolyse des esters avec formation de méthanol et d'acétate, ensuite une dégradation des liaisons glycosidiques avec décomposition du polymère. Lorsque la température s'élève, on favorise le deuxième type de réaction. Par contre, si la température s'abaisse, c'est la première réaction qui prédomine et on obtient un pectacte de calcium insoluble.Pectic substances are linear polymers of galacturonic acid. Part of the carboxyl groups is methylated, part of the hydroxyl groups is acetylated. When pectic materials are treated with lime, there are two reactions, first hydrolysis of the esters with formation of methanol and acetate, then degradation of the glycosidic bonds with decomposition of the polymer. When the temperature rises, the second type of reaction is favored. On the other hand, if the temperature drops, it is the first reaction which predominates and an insoluble calcium pectact is obtained.
La technique antérieure consistait donc, soit à traiter les cossettes de betteraves avec de la chaux, généralement sous forme de lait, soit à ajouter de la chaux dans l'eau servant à l'extraction par diffusion.The prior art therefore consisted either in treating the beet chips with lime, generally in the form of milk, or in adding lime to the water used for extraction by diffusion.
Ces procédés n'ont eu aucun succès parce que, à la température retenue pour l'action de la chaux sur le jus cellulaire de betteraves, les ions OH- coupent les liaisons glycosidiques des groupements carboxyliques et détruisent la chaîne pectique. La dégradation des pectines favorisant la dissolution de la hémicellulose du tissu, cela diminue fortement la rigidité des cossettes, empêche la percolation du liquide d'extraction et rend difficile le pressage ultérieur des cossettes épuisées.These processes have had no success because, at the temperature chosen for the action of lime on cellular juice from beets, OH- ions cut the glycosidic bonds of carboxylic groups and destroy the pectic chain. The degradation of the pectins favoring the dissolution of the hemicellulose of the tissue, this greatly reduces the rigidity of the cossettes, prevents the percolation of the extraction liquid and makes it difficult to press the exhausted cossettes subsequently.
La présente invention vise à permettre la fixation d'ions calcium sur les chaînes galacturoniques de la betterave découpée en cossettes, préalablement à l'opération d'extraction, notamment par diffusion, sans détruire les liaisons glycosidiques.The present invention aims to allow the fixation of calcium ions on the galacturonic chains of the beet cut into pods, prior to the extraction operation, in particular by diffusion, without destroying the glycosidic bonds.
A cet effet, la présente invention a pour objet un procédé d'extraction du jus de betteraves, notamment par diffusion, du type comportant un traitement préalable des betteraves découpées en cossettes par des ions calcium, caractérisé en ce que l'on effectue ledit traitement préalable par traitement des cossettes avec une solution aqueuse de saccharate de calcium, à une température inférieure à 15°C.To this end, the present invention relates to a process for extracting beet juice, in particular by diffusion, of the type comprising a prior treatment of beets cut into chips with calcium ions, characterized in that said treatment is carried out beforehand by treating the cossettes with an aqueous solution of calcium saccharate, at a temperature below 15 ° C.
Le saccharate de calcium peut être du mono- ou du di-saccharate de calcium, à condition qu'il soit soluble dans les conditions de la réaction. En pratique, on préfère utiliser du monosaccharate de calcium.The calcium saccharate can be calcium mono- or di-saccharate, provided that it is soluble under the conditions of the reaction. In practice, it is preferred to use calcium monosaccharate.
La réaction peut, en pratique, être effectuée à une température de 0 à 15°C. Au-delà, on risque de décomposer le saccharate de calcium.The reaction can, in practice, be carried out at a temperature of 0 to 15 ° C. Beyond that, there is a risk of breaking down the calcium saccharate.
La solution aqueuse de saccharate de calcium peut être obtenue par dissolution du sel dans de l'eau. Cette solution contient avantageusement de 1 à 15 % en poids de saccharate de calcium.The aqueous calcium saccharate solution can be obtained by dissolving the salt in water. This solution advantageously contains from 1 to 15% by weight of calcium saccharate.
Toutefois, dans un mode de réalisation avantageux du procédé, on fabrique directement la solution de saccharate de calcium par addition de chaux vive à un jus de diffusion.However, in an advantageous embodiment of the method, the solution is produced directly calcium saccharate by adding quicklime to a diffusion juice.
L'invention est exposée ci-après plus en détail à l'aide d'un dessin représentant seulement un mode d'exécution.The invention is explained below in more detail using a drawing representing only one embodiment.
Sur ce dessin, la Figure unique est un schéma d'une installation pour la mise en oeuvre du procédé selon la présente invention.In this drawing, the single figure is a diagram of an installation for implementing the method according to the present invention.
L'installation représentée schématiquement sur la Figure unique comprend un appareil de traitement A. Les betteraves découpées en cossettes pénètrent en 1 dans cet appareil, par exemple à percolation, qui reçoit en 11 un jus saccharaté à une température inférieure à 15°C.The installation shown schematically in the single figure comprises a processing device A. The beets cut into pods enter at 1 into this device, for example percolating, which receives in 11 a saccharated juice at a temperature below 15 ° C.
Après réaction et fixation du calcium, les cossettes sortent en 2 et sont réchauffées dans un échangeur de chaleur B,par exemple à percolation,au moyen de jus de diffusion à 70°C entrant en 6. Les cossettes qui sortent en 3 de l'échangeur B sont envoyées dans un échaudoir C qui reçoit en 4 un jus d'échaudage (jus de diffusion prélevé dans le procédé et préalablement réchauffé). Le mélange jus-cossettes réchauffé à 70°C sort en 5 de l'échaudoir C et est envoyé dans un appareil d'extraction par diffusion,non représenté, où s'opère la diffusion pendant de 50 à 80 mn.After reaction and fixing of the calcium, the pods come out in 2 and are heated in a heat exchanger B, for example percolation, by means of diffusion juice at 70 ° C. entering in 6. The pods which come out in 3 of the exchanger B are sent to a scalder C which receives in 4 a scalding juice (diffusion juice taken in the process and previously reheated). The juice-pod mixture heated to 70 ° C. leaves at 5 from the scalder C and is sent to a diffusion extraction apparatus, not shown, where the diffusion takes place for 50 to 80 minutes.
Les pulpes sortant de l'appareil d'extraction par diffusion subissent un pressage classique, par exemple au moyen de presses à vis, amenant la teneur en matières sèches de pulpes à plus de 40 %.The pulps leaving the diffusion extraction apparatus undergo conventional pressing, for example by means of screw presses, bringing the dry matter content of pulps to more than 40%.
Une partie du jus soutiré en 7 de l'échangeur B est amenée en 8 à un échangeur de chaleur D, où ce jus est refroidi à 4°C au moyen d'eau glacée entrant en 15 et sortant en 16.A part of the juice withdrawn at 7 from the exchanger B is brought at 8 to a heat exchanger D, where this juice is cooled to 4 ° C. by means of ice water entering at 15 and leaving at 16.
Le jus refroidi sortant en 9 de l'échangeur D est introduit dans un réacteur E dans lequel on introduit également en 10 de la chaux vive en poudre. La durée de réaction est d'environ 10 mn. Le jus saccharaté qui sort en 11 est envoyé à l'appareil A comme indiqué ci-dessus.The cooled juice leaving at 9 from the exchanger D is introduced into a reactor E in which also introduces 10 quicklime powder. The reaction time is approximately 10 min. The saccharated juice which leaves at 11 is sent to the apparatus A as indicated above.
Le jus sortant en 12 de l'appareil de traitement A et le reste du jus, évacué en 13, qui n'est pas prélevé de l'échangeur B pour la préparation du jus saccharaté sont réunis en 14 et récupérés.The juice leaving at 12 from the treatment apparatus A and the rest of the juice, discharged at 13, which is not withdrawn from the exchanger B for the preparation of the saccharated juice are combined at 14 and recovered.
A titre d'exemple, on introduit dans l'appareil de traitement A, en 1, 1000 kg de cossettes à 10°C et, en 11, 227 kg de jus saccharaté à 10°C (pH = 12,6).By way of example, there are introduced into treatment apparatus A, at 1, 1000 kg of cossettes at 10 ° C. and, at 11, 227 kg of saccharated juice at 10 ° C. (pH = 12.6).
On obtient en 2, 1100 kg de cossettes calciques à 10°C, qui sont introduites dans l'échangeur B. On envoie par ailleurs dans l'échangeur B, en 6, 1413 kg de jus de diffusion à 70°C.2.100 kg of calcium chips are obtained at 10 ° C., which are introduced into the exchanger B. In addition, the exchanger B is sent at 6.11413 kg of diffusion juice at 70 ° C.
On obtient en 3, 1220 kg de cossettes calciques à 54°C qui sont introduites dans l'échaudoir C avec 2425 kg de jus d'échaudage à 75°C. 3645 kg de mélange jus/cossettes à 70°C sont envoyés, en 5, dans l'appareil d'extraction par diffusion.In 3, 1220 kg of calcium chips are obtained at 54 ° C. which are introduced into the scalder C with 2425 kg of scalding juice at 75 ° C. 3645 kg of juice / pod mixture at 70 ° C. are sent, in 5, to the diffusion extraction apparatus.
De l'échangeur B sortent 1313 kg de jus de diffusion redroidi à 33°C, dont 220 kg sont envoyés en 8 à l'échangeur D. Après refroidissement à 4°C, les 220 kg de jus de diffusion sont additionnés de 7 kg de chaux vive en poudre à 10°C, dans le réacteur E.From the exchanger B, 1313 kg of diffusion juice cooled to 33 ° C. come out, of which 220 kg are sent in 8 to the exchanger D. After cooling to 4 ° C., the 220 kg of diffusion juice are added with 7 kg quicklime powder at 10 ° C, in reactor E.
Après réaction et traitement dans l'appareil de traitement A, on évacue, en 12, 127 kg de jus potassique (après échange des ions potassium avec les ions calcium).On soutire,en 14, un total de 1220 kg de jus.After reaction and treatment in the treatment apparatus A, 12,127 kg of potassium juice are removed (after exchange of potassium ions with calcium ions). A total of 1,220 kg of juice is withdrawn at 14.
Le procédé selon l'invention permet d'améliorer la pureté des jus d'extraction, de diminuer le temps d'extraction (de l'ordre de 20 %) et d'améliorer la filtrabilité des jus.The method according to the invention makes it possible to improve the purity of the extraction juices, to reduce the extraction time (of the order of 20%) and to improve the filterability of the juices.
Le procédé selon l'invention permet, en outre, d'améliorer les conditions de pressage des pulpes épuisées, grâce à la texture plus rigide conférée par la fixation des ions calcium. Ainsi, on peut obtenir grâce au procédé selon la présente invention des pulpes pressées ayant une teneur en matières sèches de plus de 40 %, alors que les procédés traditionnels permettent d'obtenir des pulpes ayant au maximum des teneurs en matières sèches de 27 à 28 %. Le procédé selon l'invention permet donc de réaliser des économies d'énergie très importantes.The method according to the invention also makes it possible to improve the pressing conditions for spent pulps, thanks to the more rigid texture imparted by the fixation of calcium ions. So we can get thanks to the process according to the present invention, pressed pulps having a dry matter content of more than 40%, while the traditional processes make it possible to obtain pulps having maximum dry matter contents of 27 to 28%. The method according to the invention therefore makes it possible to achieve very significant energy savings.
