Abstract

The method involves providing a supply of bagasse of sugarcane, and performing a step of malaxation of the bagasse of sugar cane to obtain a paste. A bleaching step is performed with oxygen of the paste. A dye is added to the bleached paste. A homogenization step is performed by malaxation of the colored paste. A container is molded from the homogenized paste. The dye is designed to mix in a uniform manner with the bagasse of sugarcane.

Description

La présente invention concerne un procédé de fabrication d'une barquette colorée et biodégradable ainsi qu'une telle barquette. Il existe actuellement des barquettes colorées qui sont destinées à contenir des produits alimentaires. Ces barquettes sont constituées de polystyrène et ne sont pas biodégradables. Un objet de la présente invention est de proposer une barquette colorée et biodégradable. A cet effet, est proposée un procédé de fabrication d'une barquette colorée et biodégradable comportant: - une étape de fourniture de bagasse de canne à sucre, - une étape de malaxage de ladite bagasse de canne à sucre pour obtenir une pâte, - une étape de blanchiment à l'oxygène de la pâte ainsi obtenue, - une étape d'ajout d'un colorant à la pâte ainsi blanchie, - une étape d'homogénéisation par malaxage de la pâte ainsi colorée, et - une étape de moulage de la barquette à partir de la pâte ainsi homogénéisée. Avantageusement, le colorant est le produit proposé par la société CLAMANT sous le nom DIRESUL BLACK P-FT LIQUID ou le produit proposé par la société CLAMANT sous le nom DIRESUL BLACK RDT KAS LIQ.The present invention relates to a method of manufacturing a colored and biodegradable tray and such a tray. There are currently colorful trays that are intended to contain food products. These trays are made of polystyrene and are not biodegradable. An object of the present invention is to provide a colored and biodegradable tray. For this purpose, there is provided a method of manufacturing a colored and biodegradable tray comprising: a step of supplying sugarcane bagasse, a step of kneading said bagasse of sugar cane to obtain a paste, a oxygen bleaching step of the dough thus obtained, a step of adding a dye to the dough thus bleached, a step of kneading homogenization of the thus colored dough, and a molding step of the tray from the dough and homogenized. Advantageously, the dye is the product offered by the company CLAMANT under the name DIRESUL BLACK P-FT LIQUID or the product offered by the company CLAMANT under the name DIRESUL BLACK RDT KAS LIQ.

L'invention propose également une barquette colorée et biodégradable obtenue par un procédé selon l'une des variantes précédentes. Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante. Une barquette colorée et biodégradable selon l'invention prend la forme d'une cuvette et elle est réalisée par moulage de bagasse de canne à sucre qui est colorée avant le moulage. Le procédé de fabrication d'une barquette colorée et biodégradable selon l'invention comporte: - une étape de fourniture de bagasse de canne à sucre, - une étape de malaxage de ladite bagasse de canne à sucre pour obtenir une pâte, - une étape de blanchiment à l'oxygène de la pâte ainsi obtenue, - une étape d'ajout d'un colorant à la pâte ainsi blanchie, - une étape d'homogénéisation par malaxage de la pâte ainsi colorée, et - une étape de moulage de la barquette à partir de la pâte ainsi homogénéisée. Le colorant est prévu pour se mélanger de manière uniforme à la bagasse de canne à sucre malaxée. Le colorant doit être adapté au contact alimentaire et ne pas déteindre.The invention also proposes a colored and biodegradable tray obtained by a method according to one of the preceding variants. The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description. A colored and biodegradable tray according to the invention takes the form of a bowl and is made by molding bagasse sugar cane which is colored before molding. The method of manufacturing a colored and biodegradable tray according to the invention comprises: a step of supplying sugarcane bagasse, a step of kneading said bagasse of sugar cane to obtain a paste, a step of oxygen bleaching of the dough thus obtained, a step of adding a dye to the dough thus bleached, a step of homogenization by kneading of the thus colored dough, and a molding step of the container. from the dough thus homogenized. The dye is intended to blend uniformly with the mixed sugarcane bagasse. The dye must be suitable for food contact and do not rub off.

De manière préférentielle, le colorant colorie la bagasse de canne à sucre en noir ce qui permet de mieux faire ressortir les produits tels que la viande et le fromage, tout en rendant invisibles les traces de sang dans le cas de la viande. De manière préférentielle, le colorant est le produit proposé par la société CLAMANT sous le nom DIRESUL BLACK P-FT LIQUID ou le produit proposé par 10 la société CLAMANT sous le nom DIRESUL BLACK RDT KAS LIQ. Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Preferably, the dye stains the bagasse of sugar cane black which allows to better highlight the products such as meat and cheese, while making invisible traces of blood in the case of meat. Preferably, the dye is the product offered by the company CLAMANT under the name DIRESUL BLACK P-FT LIQUID or the product offered by the company CLAMANT under the name DIRESUL BLACK RDT KAS LIQ. Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of numerous variants accessible to those skilled in the art.
