Description

Title of the invention: Process and system for processing at least one plant resource

[0001] 1. Scope of the invention

[0002] The present application for invention is in the field of biorefining or agrorefining of plant resources and in particular of molecular extraction from natural solvent.

[0003] 2. Prior Art

[0004] There are many varieties of plant resources that are exploited and processed to serve many applications.

[0005] For example, plant resources from the algae family have been recognized for several centuries for their multiple advantages in the manufacture of agricultural, cosmetic, food products and more recently for the manufacture of biomaterials (bioplastics, bio-based paints, etc...).

[0006] In parallel, given this multiplicity of applications, the demand for algal plant resources has logically increased significantly at the global level.

[0007] It therefore becomes essential to manage and optimize the biomass of the algal plant resources produced.

[0008] In this respect, one of the challenges is to integrate upstream the production of algal plant resources, whether by collection from the natural environment (fishing, harvesting) or by cultivation (algae farming), into a sustainable framework.

[0009] This involves, for example, cutting rules, the establishment of fallow periods, respecting reproduction periods, selecting seeds from local algal plant resource strains within the framework of seaweed farming activities, etc.

[0010] Once produced, the stabilization of fresh algal plant resources, for example through drying, makes it possible to build up stocks of stabilized algal plant resources and to implement efficient exploitation measures.

[0011] The stabilization of fresh algal plant resources also allows for Stockpiling is recommended when the composition of algal plants, particularly their active or valuable molecules, is optimal in their natural environment. Indeed, variations in the composition of algal plant resources are very frequent, and seasonal harvesting in relation to a given application can be advantageous. For example, the active molecule content of summer and / or early autumn algal plant resources is often particularly optimal for the manufacture of biostimulants and biocontrol products that utilize them.

[0012] Algal plant resources can therefore be produced at the best time of year to ensure optimized stock renewal while ensuring the performance of manufactured products.

[0013] Another complementary way of proceeding concerns downstream management, that is to say during the stages of transformation of the algal biomass produced.

[0014] Thus, components naturally present in algal plant resources can, if separated during the transformation process, be used in different fields of application.

[0015] The combination of upstream and / or downstream management of the exploitation of algae biomass places this activity within a comprehensive sustainability framework with certain environmental, economic, regulatory and social benefits.

[0016] This is all the more true since algal plant resources capture CO2 during their life cycle, grow in the sea (absence of spatial competition with terrestrial spaces) and do not require inputs (neither fresh water nor fertilizer).

[0017] Post-processing products are also beneficial since they most often consist of substituting chemical inputs with natural raw materials in various fields of application, for example: substitutes and / or better use of applied fertilizers, substitutes for pesticides, substitutes for chemical therapies for livestock, manufacture of bio-based materials, etc. They also have the advantage of protecting the health of their users (farmers, production agents, etc.) and of people in the surrounding area (for example, the neighbors of a company).

[0018] Currently, the processing of algal plant resources is sector-specific. Specialized manufacturers generally produce, in single-product mode, and from fresh algal plant resources, texturizing products, agricultural products, food products, cosmetic products, biomaterials, etc.

[0019] The manufacture of these products based on fresh algal plant resources requires extraction steps from the raw material in order to isolate the molecules of interest or active molecules for the desired final applications.

[0020] Generally, these molecules of interest or active molecules represent only a few percent of the raw material.

[0021] Moreover, the extraction steps are most often carried out using processes with chemical auxiliaries such as hard acids, alcohols, strong bases, etc... and are generally mixed with city soft water and / or demineralized water which itself becomes a rare and expensive resource.

[0022] These chemical processes generate both liquid and solid extraction residues, most often rendered unusable, and also generate sometimes significant costs for their treatment and / or decontamination.

[0023] In the end, a significant portion of the initial raw algal biomass is not exploited and is therefore wasted.

[0024] In addition, manufacturers must supply chemical auxiliaries at a certain cost, store them and handle them with certain risks for operators.

[0025] The documents below, based on the state of the art, propose extraction solutions based on the use of different chemical auxiliaries and present numerous disadvantages such as the use of strong chemical auxiliaries and / or significant biomass losses:

[0026] - Document FR3025699A1 - Concentrated seaweed extract, preparation process and its uses in agriculture.

[0027] - Document EP2778178B1 - Process for the extraction of polysaccharide from algae brown by a chemical process using microwaves.

[0028] - Document CA2891154A1 - Process for producing a biostimulant based on algae marines.

[0029] - Document WO2020254407A1 - Composition and method for improving the plant growth.

[0030] Therefore, a new process for processing at least one fresh plant resource is proposed, aiming to valorize 100% of its biomass in accordance with the concept of a biorefinery or agrorefinery, while avoiding the problems of pollution and waste management of existing extraction processes, in order to meet a range of virtuous applications.

[0031] 3. Description of the invention

[0032] The invention improves upon the state of the art and proposes to this end a process for processing at least one fresh plant resource without using a chemical process so as to maximize the value of at least one plant resource for different fields or types of applications by exploiting one hundred percent of its original biomass in accordance with the concept of a biorefinery or agrorefinery and thus avoiding the problems of pollution, waste management, etc.

[0033] To this end, it proposes a process for treating at least one plant resource, implemented by a system for treating at least one plant resource, this process being characterized in that it comprises:

[0034] - a first step of supplying a quantity of said at least one fresh plant resource,

[0035] - a second dehydration step of said a quantity or part of said minus a fresh plant resource supplied, according to a dehydration method low temperature suitable for said at least one plant resource, for a predetermined dehydration time, at a predetermined dehydration temperature, allowing the obtaining of a quantity of said at least one dehydrated plant resource and a volume of intracellular water extracted from said at least one freshly supplied plant resource,

[0036] - a third grinding stage, according to a predetermined grinding method adapted to said at least one plant resource, of a predetermined quantity of said at least one dehydrated plant resource obtained allowing the obtaining of a quantity of said at least one dehydrated and ground plant resource,

[0037] - a fourth molecular extraction and transfer step adapted to said at least one plant resource, by carrying out, at a predetermined extraction and molecular transfer temperature and for a predetermined extraction and molecular transfer time, a mixture of a predetermined quantity of said at least one dehydrated and ground plant resource obtained and a predetermined volume of intracellular water obtained, and allowing the extraction of at least one active molecule from said at least one dehydrated and ground plant resource obtained and mixed, and the transfer of said at least one extracted active molecule to said predetermined volume of intracellular water obtained and mixed,

[0038] - a fifth step of separating said extraction and transfer mixture molecular allowing the obtaining of a quantity of said at least one dehydrated, ground, moistened plant resource following mixing, and stripped of said at least one extracted active molecule and then of a volume of intracellular water containing said at least one transferred active molecule,

[0039] - a sixth drying step, according to a low temperature drying method predetermined, for a predetermined drying time, at a predetermined drying temperature, of said a quantity of said at least one dehydrated, ground, moistened plant resource, discharged of said at least one extracted and separated active molecule resulting in the obtaining of a quantity of said at least one ground, moistened, ground, moistened, dried, and discharged plant resource and a volume of intracellular water.

[0040] Advantageously, according to the invention, it is possible, for a quantity of at least one fresh plant resource supplied, to enable, after processing, the recovery of one hundred percent of it while meeting multiple application needs and thus ensuring its optimal use and valorization. Indeed, after each processing step, the solid or liquid materials obtained are usable in the short or long term, for at least one application, the chemical treatment(s) being absent from the process.

[0041] Thus, the said at least one fresh plant resource supplied is usable by the said process or for other industrial applications.

[0042] Said at least one fresh plant resource supplied and dehydrated in low temperature mode allows optimal preservation and stabilization of the active and concentrated molecules due to dehydration for longer or shorter periods and is usable by said process or for other applications.

[0043] Advantageously, according to the invention, the volume of intracellular water obtained by dehydration and / or low-temperature drying, which represents a significant portion of the biomass of at least one plant resource, is used by said process and for other applications as a molecular extraction solvent in place of a chemical solvent, and also for other types of applications, for example, cosmetic products that require a liquid organic ingredient in their composition in order to be able to use the organic label. Furthermore, the volume of intracellular water obtained can be used for cleaning applications at production sites in place of municipal water.

[0044] The quantity of said at least one plant resource dehydrated in low temperature mode and ground or micronized allows, in addition to the advantages of storage optimization, optimized molecular extraction yields thanks in particular to a maximum contact surface of plant resource with the volume of intracellular water used as extraction solvent for said process or for other applications.

[0045] The predetermined quantity of at least one plant resource dehydrated in low temperature mode, ground or micronized, moistened by mixing with the predetermined volume of intracellular water allows for molecular extraction for said process.

[0046] The predetermined volume of intracellular water charged with at least one active molecule is usable for at least one application, for example for agricultural applications of the biostimulant type.

[0047] The quantity of at least one plant resource dehydrated in low temperature mode, ground or micronized, wetted during mixing then dried and stripped of at least one active molecule is usable by industrial applications such as animal feed by incorporating this solid material obtained.

[0048] Advantageously, the invention generates other benefits such as a better ability to meet regulatory constraints. For example, with regard to regulations on heavy metals, solid / liquid separation techniques make it possible to diffuse these heavy metals over both products (solid and liquid). making them legally compatible where the entire plant resource is not necessarily so.

[0049] Intracellular water means the liquid part resulting from the dehydration and / or low-temperature drying of said at least one plant resource.

[0163] During the first supply step (El 10), the process begins with the supply and storage of a quantity of at least one fresh plant resource (Q-RVF), for example one tonne of brown macroalgae Ascophyllum nodosum freshly harvested by a seaweed harvester.

[0164] The brown macroalga Ascophyllum nodosum plant resource is unique in that it is widely used in multiple fields of application. It is indeed a macroalga authorized for human consumption and is widely used in the manufacture of agricultural products such as biostimulants to improve plant health, mycotoxin-binding products to improve animal health, as well as cosmetics, texturizing agents, biomaterials, etc.

[0165] According to a particular embodiment of the invention, the quantity or part of the quantity of freshly supplied brown macroalga Ascophyllum nodosum (Q-RVFA) is stored in a cold room, at a storage temperature between 0 and 4 degrees, for a maximum period of 48 hours.

[0166] During the second dehydration step (El20) of the process, which must be carried out as quickly as possible to best preserve the molecular qualities of at least one plant resource, the quantity (or part) of freshly supplied brown macroalgae Ascophyllum nodosum (Q-RVFA) is placed in a low-temperature dehydration device to dehydrate and thus stabilize it for a period of use of up to several years. For example, the tonne of freshly supplied brown macroalgae Ascophyllum nodosum (Q-RVFA) is distributed manually or mechanically into a plurality of highly perforated plastic and / or mechanical bins stacked vertically on trolleys.The trolleys are then placed in a line in at least one dehydration chamber in which a continuous flow of low-temperature dry hot air passes through a closed circuit, heated for example by an aerothermal heating device and blown for example by a blowing / ventilation device, for example at a predetermined temperature between 30°C and 60°C and preferably between 35°C and 40°C and for a predetermined duration of between 24 hours. at 48 hours. Thus, the continuous flow of dry, low-temperature hot air becomes saturated with moisture upon contact with the surface of the fresh brown macroalgae (Q-RVFA) supplied and placed in the multiple trays on the trolleys. It is therefore important to distribute the quantity of brown macroalgae as evenly as possible across the multiple trays and that these trays have sufficient perforations to maximize the contact of the continuous flow of dry, hot air circulating within the chamber with the surface of at least one plant resource to be dehydrated, thereby reducing the dehydration time and its energy cost. The continuous flow of low-temperature, moisture-laden hot air is then dehumidified, for example, by an air dehumidifier located at the end of the chamber, and the dehumidified hot air is then reintroduced into the closed-loop dry hot air supply circuit.Thus, the dehumidification device recovers, after condensation, a volume of intracellular water (V-EI). After the second stage (E120), from the tonne of fresh Ascophyllum nodosum brown macroalga supplied, approximately 250 kilograms of dehydrated Ascophyllum nodosum brown macroalga (Q-RVD) and approximately 750 litres of intracellular water (V-EI) are obtained.

[0167] It is noted that the quantity of dehydrated brown macroalga Ascophyllum nodosum (Q-RVD) obtained may contain a residual moisture content of around 8% to 15%, which is quite acceptable to preserve and stabilize the molecular qualities.

[0168] It is also noted that the intracellular water obtained is salt-free and virtually mineral-free. This intracellular water is similar to demineralized water and can be used for numerous applications: replacing tap water, which is becoming increasingly expensive and a scarce resource, as a basic ingredient for cosmetic applications, etc., and in the context of the invention, it is used as a natural solvent for molecular extraction.

[0169] According to a particular embodiment of the invention, the intracellular water volume (V-EI) obtained is filtered, for example, by passing it through a 5-micron cartridge filter.

[0170] According to a particular embodiment of the invention, the intracellular water volume (V-EI) obtained is sterilized, for example, by passing it through an ultraviolet lamp device.

[0171] According to a particular embodiment of the invention, the volume of intracellular water (V-EI) obtained and optionally filtered and / or sterilized is stored in an intracellular water tank, knowing that the volume of intracellular water is usable by a plurality of applications and in particular for said process as a natural molecular extraction solvent.

[0172] According to a particular embodiment of the invention, the quantity of dehydrated brown macroalga Ascophyllum nodosum (Q-RVD) obtained is stored in packaging suitable for at least one dehydrated plant resource.

[0173] According to a particular embodiment of the invention, the second step (E120) is carried out after an optional pre-washing step of the tonne of fresh Ascophyllum nodosum brown macroalga supplied (Q-RVFA) and carried out from a washing device, for example by placing it on a conveyor belt passing through a wash water which may be city water or intracellular water from the second step (E120) of the process or previously stored in an intracellular water tank and a shaking conveyor belt type dewatering device, this optional pre-washing step may be necessary depending on the type, the state of said at least one plant resource supplied and / or the type or field of application intended.

[0174] According to a particular embodiment of the invention, the second step (E120) is carried out after an optional pre-grinding step of the tonne of freshly supplied brown macroalgae Ascophyllum nodosum (Q-RVFA) and carried out from a grinding device, for example mechanical knives, this optional step being necessary to facilitate / optimize the storage and / or handling of at least one freshly supplied plant resource (Q-RVFA), and then to optimize in time and cost the dehydration step (E120).

[0175] According to a particular embodiment of the invention, the second step (E120) is carried out after an optional pre-drying step of the tonne of freshly supplied brown macroalgae Ascophyllum nodosum (Q-RVFA), for example by placing it in an outdoor greenhouse for a predetermined period, this optional step being necessary to optimize in time and cost the dehydration step (E120) or to manage stocks of at least one freshly supplied plant resource and in particular to stabilize it.

[0176] It should be noted that the optional pre-washing, pre-grinding, and pre-drying steps may not follow this order. For example, the optional pre-drying step may be carried out before the optional pre-grinding step. Similarly, the optional pre-washing step may be carried out after the optional pre-grinding step. Likewise, the optional pre-grinding step may be carried out before the optional pre-washing step.

[0177] During the third grinding step (E130) of the process, the quantity of dehydrated brown macroalga Ascophyllum nodosum (Q-RVD) obtained in the second step (E120) is ground and / or micronized via a grinding and / or micronization device. This third grinding and / or micronization step (E130) transforms the quantity of dehydrated brown macroalga Ascophyllum nodosum (Q-RVD) into a quantity of dehydrated and ground brown macroalga Ascophyllum nodosum (Q- RVDB) in the form of particles between 20 microns and 10 millimeters, preferably between 300 microns and 5 mm. This third grinding step (El30) is particularly necessary to optimize the molecular extraction yields of at least one plant resource, notably through a larger contact surface between the molecular extraction solvent and the plant resource. Furthermore, this third grinding and / or micronization step (El30) facilitates the storage of the quantity of dehydrated and ground brown macroalga Ascophyllum nodosum (Q-RVDB) that can be used by numerous industrial companies for various applications.

[0178] According to a particular embodiment of the invention, the quantity of dehydrated and ground and / or micronized brown macroalga Ascophyllum nodosum (Q-RVDB) obtained in the third grinding step (El30) is calibrated using a calibrator so as to facilitate the fifth separation step (El50).

[0179] According to a particular embodiment of the invention, the quantity of dehydrated and ground and / or micronized brown macroalga Ascophyllum nodosum (Q-RVDB) obtained in the third grinding step (El30) is stored in packaging suitable for at least one dehydrated and ground and / or micronized plant resource.

[0180] During the fourth mixing step (El40) of the process, a predetermined quantity of dehydrated and ground brown macroalga Ascophyllum nodosum (QP-RVDB) obtained in the third grinding step (El30) and then optionally calibrated is inserted into a mixing tank and a predetermined volume of Intracellular Water (VP-EI) obtained in the second dehydration step (El20) and / or previously stored in an intracellular water storage tank and optionally filtered and / or sterilized is added,Then, the contents of the mixing tank are mixed using a mixer, blender, or agitator to perform the molecular extraction of at least one active molecule or molecule of interest from the predetermined quantity of dehydrated and ground brown macroalga Ascophyllum nodosum (QP-RVDB). This active molecule or molecule of interest is then transferred to a predetermined volume of intracellular water (VP-EI), optionally filtered and / or sterilized, which acts as a natural extraction solvent. For example, by mixing for a predetermined duration of between 3 and 24 hours, preferably between 5 and 15 hours for the intended application, at a predetermined mixing temperature of 20°C, and therefore, in this case, eliminating the need for heating or cooling the mixture at the mixing device level.a predetermined volume of 1000 litres of intracellular water obtained partly in the second dehydration stage (E120) of said process and partly from intracellular water previously obtained and stored in the tank, of intracellular water, optionally filtered and / or sterilized, with a predetermined quantity of 1% to 50% of dehydrated and ground and / or micronized Ascophyllum nodosum brown macroalgae obtained (QP-RVDB) in the third grinding step (E130), i.e., 2.5 kilograms to 125 kilograms, and preferably, for the intended application, between 8% and 15%, i.e., 20 kilograms to 37.5 kilograms. At least two active molecules are extracted from said predetermined quantity of said at least one dehydrated and ground plant resource (QP-RVDB) and transferred into the predetermined volume of intracellular water (VP-EI), namely the molecule mannitol, recognized, for example, as a molecule of interest for biostimulant applications, with an extraction yield of between 90% and 100%, and then the molecule laminarin, recognized, for example, as a molecule of interest for applications in biocontrol, with an extraction yield of between 80% and 100%.Conversely, molecules of interest for other application sectors such as alginate molecules remain present with a rate of between 95% and 100% in the predetermined quantity of ground dehydrated brown macroalga Ascophyllum nodosum (QP-RVDBet mixed. .

[0181] According to a particular embodiment of the invention, the fourth mixing step (El40) uses a predetermined quantity of a plurality of fresh plant resources dehydrated during the dehydration step (E120) and ground during the dehydration step (El30) and optionally calibrated or previously stored in at least one tank of dehydrated and ground plant resource, and / or a predetermined volume of a plurality of intracellular waters optionally filtered and / or sterilized and obtained from a plurality of plant resources dehydrated during the dehydration step (E120).

[0182] According to a particular embodiment of the invention, the fourth mixing step (El40) uses a predetermined volume of intracellular water already loaded with at least one active molecule (VP-EI+MA) obtained after the fifth separation step (El50) of said process and defined below. This particular embodiment of the invention makes it possible to load a plurality of active molecules from a plurality of plant resources into the predetermined volume of intracellular water.

[0183] During the fifth separation step (E150) of the process using a device for separating the solid and liquid matter of the mixture obtained in the mixing step (E140), for example a plate centrifuge or sieves with different mesh sizes, for example between 500 microns and 22 microns, stacked and vibrating, a volume of intracellular water charged with at least the two active molecules mannitol and laminarin (V-EI+MA) and a quantity of the brown macroalga Ascophyllum is obtained. dehydrated ground nodosum and moistened following mixing (Q-RVDBM) and discharged of at least 2 active molecules mannitol and laminarin.

[0184] According to a particular embodiment of the invention, the volume of intracellular water loaded with at least the 2 active molecules mannitol and laminarin (V-EI+MA) obtained in the fifth separation step (E150) is stored in an intracellular water tank loaded with the active molecule.

[0185] According to a particular embodiment of the invention, an optional coloring step by mixing the volume of intracellular water loaded with at least the 2 active molecules mannitol and laminarin (V-EI+MA) obtained in the fifth separation step (E150) with a natural dye, for example molasses, in a predetermined proportion, makes it possible to meet the requirements of manufacturers.

[0186] According to a particular embodiment of the invention, an optional preservation step makes it possible to preserve, for a predetermined period of time, the quality of the volume of intracellular water loaded with at least the 2 active molecules mannitol and laminarin (V-EI+MA) obtained in the fifth separation step (El50), by adding and mixing it, in a predetermined proportion, at least one preservative product such as citric acid, which remains compatible with human or animal food.

[0187] According to a variant of this particular embodiment of the invention, following the optional preservation step, a separation step identical to the separation step (El50) of said process is carried out so as to isolate the alginates from the liquid portion. This variant is particularly relevant for agricultural applications by preventing the clogging of farmers' spreader nozzles when spreading intracellular water containing the two active molecules mannitol and laminarin, and free of alginates. Optionally, the separated alginates can be used by dehydrating or drying them according to the second dehydration step (El20) of said process or according to the sixth drying step (El60) of said process, and then grinding them according to the third grinding step (El30) of said process so as to be able to utilize them for various applications such as the manufacture of bioplastics or algae-based paints.

[0188] According to a particular embodiment of the invention, the quantity of dehydrated, ground, moistened brown macroalga Ascophyllum nodosum following mixing and discharged of the 2 active molecules mannitol and laminarin (Q-RVDBM-ma) obtained in the fifth separation step (E150) of said process is stored in a container suitable for said at least one dehydrated ground plant resource moistened following mixing and discharged of at least one active molecule.

[0189] During the sixth drying step (El60) of the process, the quantity of ground, dehydrated, moistened brown macroalga Ascophyllum nodosum (Q-RVDBM-ma), obtained in the fifth separation step (El50) of said process, is dried, for example, according to the same principle as the dehydration step (E120) of said process described above. Thus, the resulting dried product—ground, moistened brown macroalga Ascophyllum nodosum (Q-RVDBM-ma-S), dehydrated, moistened, and free of the two active molecules mannitol and laminarin—can be used, for example, in animal feed applications.

[0190] According to a particular embodiment of the invention, the quantity of dehydrated ground brown macroalga Ascophyllum nodosum wet following mixing, discharged of the 2 active molecules mannitol and laminarin and dried (Q-RVDBM-ma-S is stored in a packaging suitable for at least one dehydrated ground plant resource wet following mixing, discharged of at least one active molecule, and dried.

[0191] According to a particular embodiment of the invention, the quantity of ground, dehydrated, wet, ground brown macroalga Ascophyllum nodosum following mixing, discharged of the 2 active molecules mannitol and laminarin and dried (Q-RVDBM-ma-S) is ground (Q-RVDBM-ma-SB) according to the third grinding step (El30) already described.

[0192] Figure 2 illustrates steps in the process of processing at least one plant resource according to a particular embodiment of the invention. The process is carried out via a system SYS for processing at least one plant resource and consisting of a supply device (DA), a dehydration device (DD), a grinding and / or micronization device (DB), a mixing device (DM), a separation device (DS) and a drying device (D-SE).

[0193] A quantity of at least one fresh plant resource (Q-RVF) is supplied (Q-RVFA) during the first supply step (El 10) of the process of processing at least one plant resource and is for example stored in a supply device (DD), for example a bin or a silo or a container or a cold room.

[0194] According to a particular embodiment of the invention, the quantity of at least one fresh plant resource supplied (Q-RVFA) is pre-washed via a washing device (not shown in [Fig. 2]), for example via a conveyor belt passing through a volume of water and then a vibrating conveyor belt for spinning, particularly when the target application requires it, typically for human or animal food applications, or if the condition of the plant resource is very dirty and at risk to damage the various devices of the processing system of at least one plant resource.

[0195] According to a particular embodiment of the invention, the quantity of at least one fresh plant resource supplied (Q-RVFA) is pre-ground via a grinding device (not shown in [Fig.2]), for example a blade grinder, so as to facilitate its storage and / or facilitate its handling and / or optimize the second dehydration stage (E120).

[0196] According to a particular embodiment of the invention, the quantity of at least one fresh plant resource supplied (Q-RVFA) is pre-dried via a pre-drying device (not shown in [Fig.2]), for example via an outdoor greenhouse which allows pre-drying at zero energy cost, so as to optimize the execution time and / or the energy cost of the second dehydration step (E120).

[0197] It is noted that these particular embodiments of the invention pre-washing, pre-grinding, pre-drying can be carried out in any order after the first supply step (E10) and before the second dehydration step (E120).

[0198] All or part of this quantity of at least one fresh plant resource (Q-RVFA), optionally pre-washed and / or pre-crushed and / or pre-dried, is dehydrated during the second dehydration step (El20) of the process for treating at least one plant resource via a low-temperature dehydration device (DD) consisting, for example, of a closed chamber in which are placed a plurality of trolleys supporting a plurality of highly perforated plastic and / or metal containers loaded with all or part of the quantity of at least one fresh plant resource (Q-RVFA). The dehydration device (DD) also consists of a low-temperature heater and is equipped with ventilation, for example, of the air-source heat pump type, thus generating a continuous flow of hot, dry, low-temperature air at one end of the chamber, which then propagates throughout the entire chamber.The flow of hot, dry, low-temperature air comes into contact with at least one fresh plant resource placed in the trays, dehydrating it and yielding a quantity of the at least one dehydrated plant resource (Q-RVD) after a predetermined dehydration period, for example, 24 hours, and at a predetermined low dehydration temperature, for example, 40°C. This is because the hot, dry, low-temperature airflow becomes saturated with moisture due to continuous contact with the at least one fresh plant resource, and the at least one fresh plant resource gradually releases its moisture. The dehydration device also includes a dehumidifier for the saturated hot air, incorporating a condenser to recover a volume of intracellular water. (V-EI) and to reintroduce the flow of dehumidified hot air via ducts at the end of the chamber, thus preventing the loss of hot air. This step is necessary to stabilize at least one fresh plant resource supplied and it allows for the concentration of its active molecules by reducing its volume. Furthermore, using low-temperature dehydration ensures that the quality of the active molecules is not altered.

[0199] According to a particular embodiment of the invention, the volume of intracellular water (V-EI) obtained is stored in an intracellular water storage device (not shown in [Fig.2]), for example a tank so as to be able to process large volumes of intracellular water and usable for multiple applications, over time.

[0200] According to a particular embodiment of the invention, the intracellular water volume (V-EI) obtained is filtered via a filtering device (not shown in [Fig.2]), for example a paper and / or carbon filter cartridge at a few micrometers so as to remove any dirt or impurities.

[0201] According to a particular embodiment of the invention, the intracellular water volume (V-EI) obtained is sterilized via a sterilization device (not shown in [Fig.2]), for example an ultraviolet lamp so as to eliminate any bacteria, etc....

[0202] According to a particular embodiment of the invention, the quantity of at least one dehydrated plant resource (Q-RVD) obtained is stored in a storage device (not shown in [Fig.2]), for example a container adapted to the dehydrated plant resource so as to be able to process large quantities of at least one dehydrated plant resource and usable for multiple applications over time.

[0203] All or part of the quantity of at least one dehydrated plant resource (Q-RVD) is ground via a grinder, for example into a powder of a few millimeters, and / or micronizer, for example into a powder of a few micrometers, during the third grinding and / or micronization step (El30) of the process for treating at least one plant resource, and a quantity of the at least one dehydrated and ground plant resource (Q-RVDB) is obtained. The advantage of this step, besides the gain in storage, is in particular to facilitate molecular extraction.

[0204] According to a particular embodiment of the invention, all or part of the quantity obtained from at least one dehydrated and ground plant resource (Q-RVDB) is calibrated by passing it through a calibrator (not shown in [Fig.2]) so as to facilitate the fifth separation step (150) of the process, typically by avoiding clogging the separation sieves of the liquid and solid parts.

[0205] According to a particular embodiment of the invention, the quantity of at least one dehydrated and ground plant resource (Q-RVDB) obtained and optionally calibrated is stored in a storage device (not shown in [Fig.2]), for example packaging adapted to the dehydrated and ground plant resource so as to be able to process large quantities of at least one dehydrated and ground plant resource and usable for multiple applications over time.

[0206] A predetermined quantity of at least one dehydrated and ground plant resource (QD-RVDB), optionally calibrated, and a predetermined volume of intracellular water (VP-EI) are then mixed in the fourth mixing step (E140) of the process for treating at least one plant resource via a mixing device consisting of a tank into which the predetermined quantity of at least one dehydrated and ground plant resource (QD-RVDB), optionally calibrated, is first inserted, followed by the predetermined volume of intracellular water (VP-EI). Then, an agitator with a predetermined speed and / or acceleration stirs the mixture for a predetermined continuous or intermittent mixing time, for example, 5 hours continuous or 5 hours with one minute of stirring and one minute without stirring, at a predetermined mixing temperature, for example, 20°C or at ambient temperature. This step wets the said quantitypredetermined, for example 150 kilograms, of at least one dehydrated and ground plant resource (QD-RVDB) and optionally calibrated, with said predetermined volume, for example 1000 liters, of intracellular water (VP-EI). Thus, the predetermined volume of intracellular water (VP-EI) is advantageously used as a natural solvent for molecular extraction, and the said predetermined quantity of at least one dehydrated and ground plant resource (QD-RVDB), optionally calibrated, is discharged of at least one active molecule (ma) extracted with an extraction rate of up to 100%, depending on the type and / or quality and / or seasonality of the at least one plant resource and / or the type of active molecule sought and / or the conditions of implementation of the second dehydration step (El20) and / or the conditions of implementation of the third grinding step (El30) and / or the conditions of implementation of the fourth mixing step (El40), then saidA predetermined volume of intracellular water (VP-EI) is loaded with at least one active molecule (ma) extracted and transferred with a transfer rate of up to 100%, depending on the type and / or quality and / or seasonality of the plant resource and / or the type of active molecule sought and / or the conditions of implementation of the second dehydration step (E120) and / or the conditions of implementation of the third grinding step (E130) and / or the conditions of implementation of the fourth mixing step (E140). Thus, this step yields a mixture (Q-RVDB-ma-M with V-EI+ma) consisting of a quantity of at least one ground, dehydrated plant resource optionally calibrated with at least one extracted and wetted active molecule and a quantity of intracellular water loaded with said at least one extracted active molecule.

[0207] According to a particular embodiment of the invention, the mixture (Q-RVDB-ma-M with V-EI+ma) consisting of a quantity of at least one ground dehydrated plant resource optionally calibrated with at least one extracted and wetted active molecule and a quantity of intracellular water loaded with said at least one extracted active molecule obtained is stored in a storage device (not shown in [Fig.2]), for example a container adapted to the mixture (Q-RVDB-ma-M with V-EI+ma) so as to be able to process large quantities of this mixture before carrying out the fifth separation step (E150).

[0208] The mixture (Q-RVDB-ma-M with V-EI+ma) consisting of a quantity of at least one ground and optionally calibrated dehydrated plant resource with at least one extracted and wetted active molecule and a quantity of intracellular water loaded with said at least one extracted active molecule is separated via a solid and liquid part separator, for example via a centrifuge and / or via one or a plurality of sieves with progressively smaller mesh sizes, for example a first sieve with a 1 millimeter mesh size and then a second sieve with a 50 micrometer mesh size during the fifth separation step (El50) of the process of treating at least one plant resource.Thus, after separation, we obtain a volume of intracellular water charged with at least one active molecule (V-EI+ma) and a quantity of at least one dehydrated, ground, and optionally calibrated plant resource with at least one extracted and wetted active molecule (Q-RVDB-ma-M).

[0209] According to a particular embodiment of the invention, the quantity of at least one ground and optionally calibrated dehydrated plant resource with at least one extracted and wet active molecule Q-RVDB-ma-M obtained is stored in a storage device (not shown in [Fig.2]), for example packaging adapted to at least one ground and optionally calibrated dehydrated plant resource with at least one extracted and wet active molecule Q-RVDB-ma-M, so as to be able to process larger volumes during the sixth drying step (El 60).

[0211] According to a particular embodiment of the invention, the volume of intracellular water loaded with at least one active molecule (V-EI+ma) obtained is mixed in a predetermined proportion with at least one preservative, for example a natural preservative of the citric acid type and / or sodium benzoates and / or potassium sorbates so as to increase the shelf life of the product.

[0212] According to a particular embodiment of the invention, the volume of intracellular water loaded with at least one active molecule (V-EI+ma) obtained is pasteurized so as to increase the shelf life of the product.

[0213] According to a particular embodiment of the invention, the volume of intracellular water loaded with at least one active molecule (V-EI+ma) obtained is packaged in a Bag in Box type packaging so as to increase the shelf life of the product.

[0214] According to a particular embodiment of the invention, the volume of intracellular water loaded with at least one active molecule (V-EI+ma) obtained is mixed in a predetermined proportion with at least one dye so as to meet the requirements of certain manufacturers.

[0215] According to a particular embodiment of the invention, the volume of intracellular water charged with at least one active molecule (V-EI+ma) obtained is mixed in a predetermined proportion with at least one volume of intracellular water charged with at least one other active molecule (V-EI+ma) and obtained previously from another type of plant resource and stored so as to offer to industrialists intracellular water charged with multiple active molecules meeting different types of applications.

[0228] The SYS system for processing at least one plant resource and consisting of a supply device (DA), a dehydration device (DD), a grinding and / or micronization device (DB), a mixing and / or agitation device (DM), a separation device (DS) and a drying device (D-SE).

[0229] The supply device (SD) has a means of storage (SD), for example a tank or a bin or a silo or a cold room so as to store the quantity of at least one fresh plant resource supplied (Q-RVFA) in accordance with the supply step (El 10) of the process.

[0230] The dehydration device (DD) includes means such as an enclosure (DD1) in which is placed at least one perforated tray (DD-2) that can be placed on a trolley and loaded with a quantity of fresh plant material (Q-RVFA), said enclosure guiding a flow of hot dry and / or humid air. Furthermore, the dehydration device (DD) includes a low-temperature hot dry air blower (DD-3), for example in aerothermal mode to reduce energy costs, configurable in temperature and operating time, so as to dehydrate the quantity of fresh plant material (Q-RVFA) by contact with the flow of hot dry air circulating in the enclosure. In addition, the dehydration device (DD) includes dehumidification means (DD-4) for dehumidifying the hot dry air laden with moisture, via the principle of condensation.Thus, the dehumidified hot air stream is reintroduced via blower ducts (not shown in [Fig.4]) into the initial dry hot air stream. Therefore, after the dehydration step (El20) of the process, a quantity of at least one dehydrated plant resource (Q-RVD) and a volume of intracellular water (V-EI) are obtained.

[0231] The grinding device (DB) has a grinding means (DBl), of the type grinder and / or micronizer, of the quantity of said at least one dehydrated plant resource (Q-RVD) so as to obtain, according to the third grinding step (El30) of the process, a quantity of at least one dehydrated and ground plant resource (Q-RVDB).

[0232] The mixing device (MD) has a storage means (MD1), of the tank type, allowing the insertion of a predetermined quantity of said at least one dehydrated and ground plant resource (QP-RVDB), optionally calibrated, and then, a predetermined volume of intracellular water (VP-EI). Furthermore, the mixing device (MD) has a continuous or cyclic stirring means (MD2), of the type of paddle driven by an electric motor, so as to mix the solid and liquid parts for a predetermined time at a predetermined temperature. Thus, the fourth mixing step (El40) of the process allows for molecular extraction, from said predetermined quantity of said at least one dehydrated, ground, optionally calibrated, and wetted plant resource, of at least one active molecule and then molecular transfer, of said at least one active molecule to said predetermined volume of intracellular water.

[0233] The separation device (DS) has a means for separating the solid matter and the mixed liquid matter (DSl), for example one or a plurality of sieves with different mesh sizes, for example of SWECO separator type, and / or a centrifuge, so as to separate, in accordance with the fifth separation step (E150) of the process, a volume of intracellular water loaded with at least one active molecule (V-EI+ma) and a quantity of said at least one ground and optionally calibrated dehydrated plant resource discharged of at least one active molecule and wetted (Q-RVDB-ma-M).

[0234] The drying device (D-SE) has low temperature drying means, for example identical to those of the low temperature dehydration device (DD) previously described for drying said quantity of said at least one dehydrated, ground, optionally calibrated, discharged of at least one active molecule and wetted plant resource (Q-RVDB-ma-M) and thus obtain, according to the sixth drying step (El60) of the process, a quantity of said at least one dehydrated, ground, optionally calibrated, discharged of at least one active molecule wetted and dried plant resource (Q-RVDB-ma-MS).

[0235] It goes without saying that the embodiment described above has been given purely as an example and is in no way limiting, and that many modifications can easily be made by a person skilled in the art without going out of the scope of the invention.
