Abstract

The materials treated are of vegetable origin (various plants, artichoke stalks and the like), or of rural origin (fowl droppings and the like), or of industrial origin (beet eluates, animal hoof powder and the like, after extraction of the essential amino acids they contain). These materials are heated to a temperature of 30 to 80 DEG C, while being sterilized, the water vapour (approximately 80 % by weight of the plants and vegetable waste, for example) is recovered by being condensed, and a protein-enriched dry residue is recovered (up to 25-30 % by weight in the case of plant and vegetable waste). The pure, sterile water can be used as drinking water, the sterile dry residue as cattle feed, fertilizer or fuel. Solar energy or fuels including the dry residue itself may be employed for heating, and the heat of condensation of the water vapour and of cooling of the condensed water may serve for industrial or domestic heating, for example for heating (chicken) incubators.

Description

La présente invention a pour objet un procédé de traitement de produits agricoles et/ou de leurs déchets renfermant de l'eau et des protéines, en vue d'en extraire de l'eau pure directement potable et de recueillir un résidu sec utilisable à diverses fins. The subject of the present invention is a process for treating agricultural products and / or their wastes containing water and proteins, with a view to extracting directly potable pure water therefrom and collecting a dry residue which can be used for various purposes. purposes.

On sait que les végétaux et les déchets végétaux, herbe, queues d'artichaut, tombées de choux-fleurs et similaires contiennent en poids environ 80 % d'eau et entre 4 et 7 r de protéines. Des déchets d'origine rurale, comme les fientes de poules contiennent environ 20 % d'eau et 6 % de protéines. It is known that plants and plant waste, grass, artichoke tails, fallen cauliflowers and the like contain about 80% by weight of water and between 4 and 7 r of protein. Rural wastes such as chicken droppings contain about 20% water and 6% protein.

Des déchets industriels,. tels que les éluats de betteraves et la poudre de sabots d'animaux, que l'on traite sur échangeurs ioniques, en vue d'en extraire certains aminoacides essentiels qu'ils renferment, comme l'arginine, contiennent encore après ce traitement de l'eau et des aminoacides qu'il peut être intéressant de récupérer; après extraction des aminoacides essentiels, les éluats de betteraves, par exemple, renferment 90 % d'eau en poids.Industrial waste ,. such as beet eluates and animal hoof powder, which are treated on ion exchangers, with a view to extracting certain essential amino acids which they contain, such as arginine, still contain after this treatment the water and amino acids which can be interesting to recover; after extraction of essential amino acids, the beet eluates, for example, contain 90% water by weight.

Or, l'eau est une substance précieuse, lorsqu'elle est pure, déminéralisée et aseptique, et utilisable alors par exemple pour préparer les biberons. Actuellement, une telle eau coûte environ 2 F le litre, alors que l'eau du robinet coûte environ 2 F les 1 000 litres. However, water is a precious substance, when it is pure, demineralized and aseptic, and can then be used, for example, to prepare bottles. Currently, such water costs around 2 F per liter, while tap water costs around 2 F per 1000 liters.

Le but de l'invention est donc de traiter des produits et/ou des déchets agricoles, en vue de récupérer sous forme d'eau pure l'eau habituellement perdue qu'ils contiennent, et de tirer profit simultanément du résidu résultant de la dessiccation des matières traitées. The object of the invention is therefore to treat agricultural products and / or waste, with a view to recovering, in the form of pure water, the usually lost water which they contain, and simultaneously benefiting from the residue resulting from desiccation of the materials treated.

A cet effet, la présente invention concerne un procédé de traitement desdits produits agricoles et de leurs déchets, caractérisé en ce que l'on place ces matières dans un récipient muni d'un couvercle ou d'une trappe d'introduction des matières à traiter, ainsi que d'une trappe d'extraction du résidu du traitement située à sa base et d'une canalisation d'échappement de vapeur d'eau et de condensation de cette vapeur en eau potable, cette canalisation étant située au sommet- du récipient, en ce que l'on chauffe le récipient à une température comprise entre environ 30 et 80"C en contrôlant et réglant la température à l'intérieur du récipient au moyen d'un thermostat branché sur le récipient, en ce que l'on injecte dans le récipient une substance stérilisante de façon à stériliser simultanément l'eau qui s'évapore et le résidu qui se dessèche, et en ce que l'on recueille le condensat comme eau potable et le résidu sec et enrichi en protéines à titre d'aliment pour le bétail, ou comme engrais, ou comme combustible utilisable seul ou en mélange avec les combustibles usuels, tels que charbon, tourbe, lignite, bois, etc.. L'eau potable recueillie est non bouillie, donc plus digeste. Cette eau, vendable en tant qu'eau pure et stérile, rentabilise le procédé. To this end, the present invention relates to a method for treating said agricultural products and their waste, characterized in that these materials are placed in a container provided with a lid or a hatch for introducing the materials to be treated. , as well as a hatch for extracting the treatment residue located at its base and a water vapor exhaust pipe and the condensation of this steam into potable water, this pipe being located at the top of the container. , in that the container is heated to a temperature between about 30 and 80 "C by controlling and adjusting the temperature inside the container by means of a thermostat connected to the container, in that one injects into the container a sterilizing substance so as to simultaneously sterilize the evaporating water and the drying residue, and in that the condensate is collected as drinking water and the dry residue is enriched with proteins as for livestock, or as a feed rais, or as fuel usable alone or in mixture with the usual fuels, such as coal, peat, lignite, wood, etc. The drinking water collected is not boiled, therefore more digestible. This water, which can be sold as pure and sterile water, makes the process profitable.

La température utilisée variera avec la nature des matières traitées. C'est ainsi que, dans le cas des végétaux et de leurs déchets, tels que herbe, queues d'artichauts tombées de choux-fleurs, une température de chauffage de 40 à 80 est convenable pour évaporer l'eau et recueillir de l'eau potable. Après élimination des 80 % d'eau en moyenne que contiennent ces matières, on obtient un résidu sec stérile pouvant être enrichi en protéines jusqu'à un taux de 25 à 30 g en poids, alors que les viandes principales n'en contiennent que 22 ou 23 %. The temperature used will vary with the nature of the materials treated. Thus, in the case of plants and their waste, such as grass, artichoke tails fallen from cauliflowers, a heating temperature of 40 to 80 is suitable for evaporating water and collecting potable water. After elimination of the 80% water on average that these materials contain, a sterile dry residue is obtained which can be enriched in proteins up to a rate of 25 to 30 g by weight, while the main meats contain only 22 or 23%.

On recueille ainsi simultanément de l'eau de boisson pour lthomme et l'animal et un aliment pour le bétail.Water for human and animal consumption and animal feed are thus collected simultaneously.

La substance stérilisante est injectée dans le récipient, de préférence dès le début du traitement, pour stériliser la vapeur d'eau dès le commencement de son dégagement. Des exemples d'une telle substance sont cités dans l'ouvrage Encyclopedia
Universalis, édition 1980, page 873, au sous-chapitre "Stérilisation" du chapitre "Eau, approvisionnement et traitement"; il s'agit du chlore, de ses dérivés (peroxyde ou bioxyde dechlore) et de l'ozone ou de l'air ozoné. L'injection est avantageusement effectuée à la fois au niveau de la matière solide traitée et au niveau de la zone de dégagement de la vapeur d'eau.Elle peut avoir lieu seulement à la base du récipient s'il s'agit d'un gaz, ou seulement à son sommet s'il s'agit d'un liquide. I1 y a intérêt à libérer la vapeur d'eau sous pression en munissant le récipient d'un manomètre et le conduit d'évacuation de la vapeur d'une soupape réglée à une pression d'évacuation adéquate, afin que la vapeur séjourne dans le récipient un temps suffisant pour que la stérilisation ait lieu et afin que sa pression l'entrain automatiquement vers le récipient de condensation, d'oû elle pourra alimenter une machine automatique de mise en bouteilles de verre ou de plastique.The sterilizing substance is injected into the container, preferably at the start of the treatment, to sterilize the water vapor from the start of its release. Examples of such a substance are cited in the book Encyclopedia
Universalis, 1980 edition, page 873, in the "Sterilization" sub-chapter of the "Water, supply and treatment"chapter; these are chlorine, its derivatives (peroxide or dechlorine dioxide) and ozone or ozonated air. The injection is advantageously carried out both at the level of the solid matter treated and at the level of the steam release zone. It can take place only at the base of the container if it is a gas, or only at the top if it is a liquid. It is advantageous to release the pressurized water vapor by providing the container with a pressure gauge and the steam evacuation pipe with a valve adjusted to an adequate evacuation pressure, so that the steam remains in the container sufficient time for sterilization to take place and so that its pressure automatically drives it to the condensation container, from where it can feed an automatic glass or plastic bottling machine.

Toutes les sortes d'énergies connues sont utilisables pour chauffer le récipient par le dessous, les côtés ou le dessus
On emploie avantageusement l'énergie solaire pour chauffer par le dessus et par effet de serre le récipient sous forme de corps noir, dans le présent cas où un chauffage à une température inférieure à 100 C entralnant une évaporation relativement lente est suffisant. Pendant la période de non-ensoleillement, on peut poursuivre le chauffage, bien entendu, par le dessous et les cotés du récipient avec, comme combustible9 le résidu sec obtenu et/ou tout autre combustible.All kinds of known energies can be used to heat the container from below, sides or above
Solar energy is advantageously used to heat the container in the form of a black body above and by greenhouse effect, in the present case where heating to a temperature below 100 ° C. entailing relatively slow evaporation is sufficient. During the period of non-sunshine, it is possible to continue the heating, of course, from below and from the sides of the container with, as fuel9 the dry residue obtained and / or any other fuel.

lorsque la matière traitée est constituée par des résidus de déchets industriels, dont on a extrait des aminoacides essentiels par passage sur des échangeurs ioniques, le traitement de ces résidus par le procédé suivant l'invention, avec récupération d'eau potable et de résidus secs contenant des acides aminés et pouvant convenir aux diverses fins susindiquées, permet d'abaisser le prix de revient des aminoacides essentiels. when the treated material consists of industrial waste residues, from which essential amino acids have been extracted by passage over ion exchangers, the treatment of these residues by the process according to the invention, with recovery of drinking water and dry residues containing amino acids and being suitable for the various purposes mentioned above, makes it possible to lower the cost price of essential amino acids.

I1 y a intérêt, avec le procédé suivant l'invention, à récupérer la chaleur de condensation de la vapeur d'eau et de refroidissement de l'eau condensée, en utilisant cette vapeur pour chauffer à des fins industrielles ou domestiques. It is advantageous, with the process according to the invention, to recover the heat of condensation of the water vapor and of cooling the condensed water, by using this vapor to heat for industrial or domestic purposes.

C'est ainsi. notamment qu'on peut l'employer pour chauffer des poussinières, dans les endroits où, élevant des poules pondeuses et des poussins, on récupère de la fiente de poule, que l'on traite par leirésent procédé.  This is how. in particular that it can be used to heat chickens, in places where, raising laying hens and chicks, we recover chicken droppings, which are treated by the present process.

Des modifications de détail, du domaine des équivalents techniques, peuvent être apportées à l'invention décrite cidessus, sans que l'on sorte pour autant du cadre de l'invention.  Modifications of detail, from the field of technical equivalents, can be made to the invention described above, without departing from the scope of the invention.
