  Said process used to obtain, in industrial scale, wet sheets and membranes of bacterial cellulose of high purity and specific physical and chemical properties, using the appropriate culture medium that is prepared in a mechanical mixer furnished with a jacket for temperature control and heat exchange, using selected recycled or non-recycled inoculums, fermentation in covered trays with the temperature controlled by an external heating/cooling jacket through the circulation of hot/cold water, not requiring control of humidity and air renovation, collecting of the wet sheets that are then submitted to a process of purification and whitening by successive whirlpool washing and rinsing cycles using diverse heated or non-heated aqueous solutions, being afterwards forwarded to draining and drying/dehydration, passing through a semi-continuous system of rollers and belt conveyors made of absorbent material. This invention also refers to the process used to obtain compounded cellulosic wet sheets. When a wet sheet reaches a certain thickness, screens or other artifacts of diverse materials are added to the surface of the wet sheet already pre-formed so that in a second fermentation stage such screens and artifacts are covered by the cellulosic wet sheet, thus forming a compound product.

  [EN] The present invention refers to a continuous industrial production process to obtain bacterial cellulosic sheets with high purity and specific chemical and physical properties, which can be used for various purposes. More specifically, the invention refers to a process to obtain multiple bacterial cellulose sheets without the need to replace new fermentation medium in the tray, said process comprising the following steps: a) preparation of the fermentation medium; dissolution of medium components in water; b) sterilization of the medium: heating of medium to 115°C, keeping it at that temperature for 20 minutes; c) cooling of the medium until its temperature reaches 30 °C; d) medium inoculation with a suspension of bacteriae; e) distribution of the medium in the trays; f) the trays are left to rest during fermentation; g) harvest of the sheets, draining them over the corresponding trays; h) repetition of the fermentation in the trays left to rest during fermentation and harvest of the sheets from the trays, draining them over the corresponding trays until, after taking and draining the sheet, the volume of medium in the tray is between 15% and 25% of the initial volume; i) when the volume of 15% to 25% of the initial volume is reached, a new fermentation medium should be added to the tray in order to reach the initial volume again; j) repetition of the fermentation in the trays left to rest during fermentation and harvest of the sheets from the trays, draining them over the corresponding trays until, after taking and draining the sheet, the volume of medium in the tray is between 15% and 25% of the initial volume; when new fermentation medium is added and the cycle is re-started.
  [FR] La présente invention porte sur un procédé de production industrielle continue permettant d'obtenir des feuilles cellulosiques bactériennes de haute pureté et présentant des propriétés chimiques et physiques spécifiques, ces feuilles pouvant être utilisées pour divers besoins. Plus spécifiquement, l'invention porte sur un procédé permettant de obtenir plusieurs feuilles cellulosiques bactériennes sans avoir à remplacer le nouveau milieu de fermentation dans le plateau. Ce procédé comprend les étapes suivantes: a) la préparation du milieu de fermentation; la dissolution des composants de ce milieu dans l'eau; b) la stérilisation du milieu, c'est-à-dire chauffer le milieu à 115 °C et le conserver à cette température pendant 20 minutes; c) le refroidissement du milieu jusqu'à ce que sa température atteigne les 30 °C; d) l'inoculation du milieu par une suspension de bactéries; e) la répartition du milieu dans les plateaux; f) les plateaux sont laissés au repos pendant la fermentation; g) la récupération des feuilles en les tirant sur les plateaux correspondants; h) la répétition de la fermentation dans les plateaux laissés au repos pendant la fermentation et la récupération des feuilles sur les plateaux en les tirant sur les plateaux correspondants jusqu'à ce que, après avoir pris et tiré la feuille, le volume du milieu du plateau soit compris entre 15 % et 25 % du volume initial; i) lorsque le volume de 15 % à 25 % du volume initial a été atteint, un nouveau milieu de fermentation doit être ajouté au plateau de façon à atteindre à nouveau le volume initial; j) la répétition de la fermentation dans les plateaux laissés au repos pendant la fermentation et la récupération des feuilles du plateau en les tirant sur les plateaux correspondants jusqu'à ce que, après avoir pris et tiré la feuille, le volume du milieu du plateau soit compris entre 15 % et 25 % du volume initial; lorsque le nouveau milieu de fermentation a été ajouté, le cycle redémarre.
