Description

[0001] “PROCESS FOR PREPARATION OF VEGETABLE OR FRUIT FIBRE SURFACES”

[0002] FIELD OF THE INVENTION:

[0003] The present invention relates to a process for preparation of surfaces from organic material, more particularly to a process for preparation of vegetable or fruit fibre surfaces.

[0004] BACKGROUND OF THE INVENTION:

[0005] The history of paper dates back to the history of human culture and civilization. Handmade paper has deep roots in countries like China, Japan, and India, where it has been used for calligraphy, religious texts, and artwork for centuries. Handcrafted paper sheets are being made in India in some form or the other since the 3rd Century BC. Artisans and contemporary artists use handmade paper as both a medium and a canvas to express creativity. Conventionally, handcrafted paper is made from interwound cellulose fibres or pulp that is retrieved from wood, cloth and the like.

[0006] The traditional paper making process involves converting wood chips into pulp, which is then processed into sheets of paper. Accordingly, wood cutting is the initial step in preparing raw materials for paper production. This includes various processes such as tree selection, felling and logging, debarking and chipping. Typically, the paper making process involves pulping, bleaching, sheet formation, pressing, drying and finishing. However, rising environmental concerns including deforestation and habitat loss demand alternative solutions for paper makingprocess. This includes development of tree-free papers using agricultural waste, hemp, kenaf or other sustainable materials.

[0007] Further, surfaces of varied textures are required for various purposes be it tactile surfaces, printed surfaces for decorative purposes, corrugated surfaces, and the like. Preparing decorative surfaces, includes a wide range of techniques ranging from traditional crafting to industrial lamination. These methods are used for interior design, furniture surfacing, and artistic projects. A few of these methods include ink-fix coating, resin impregnation, finishing and the like. Similarly, there are several methods to prepare artistic or decorative surfaces such as decoupage, paper mache, layering and the like.

[0008] One type of surface is a veneer surface. Veneer refers to thin slices of wood that are typically glued onto core panels generally made of wood, particle board or medium-density fiberboard, etc. Veneers are also used in marquetry that is the art of applying pieces of veneer to a structure to form decorative patterns or designs. The typical types of veneers used in marquetry are primarily woods, but may include bone, ivory, turtle-shell (conventionally called "tortoiseshell"), mother-of-pearl, pewter, brass or fine metals.

[0009] However, all of these techniques are time consuming, require specific and skilled technicians. Further, the techniques require a large amount of raw material, leading large amounts of wastage. Also, methods such as veneering permanently change the surface and is a completely irreversible process, such that the original surface is not brought back.There have been attempts in the art to convert fruits or vegetables into sheets for various purposes such as fruit leathers that are edible, decorative and dried show pieces or the like. However, the main disadvantage of such products is the perishable nature of fruits and vegetables. The prior art is unable to preserve the fruit or vegetable products for prolonged periods of time.

[0010] The Chinese Patent Application, CN1269164A, to Wu Yonggen, relates to preservation of vegetables in the shape of paper. This process includes washing the vegetable, cooking it, grinding and making a paste out of it, followed by drying, flavouring and microwave sterilizing to result in vegetable sheets. However, these sheets are cooked and require to be refrigerated for long term storage. Further, the process of preservation is extensive and time consuming.

[0011] The Chinese Patent Application CN 102793323 A, to Wang Meijiang, relates to a production process for processing of lacebark pine cone fruits to create plum blossom handicraft articles. The process includes drying and dehydration of the lacebark pine cones and then spraying them with insecticide for efficient preservation. However, the availability of lacebark pine cone fruits is limited, making the scope of the invention limited.

[0012] There is a need for a process for preparation of surfaces from organic material like fruits or vegetables. There is also a need for a process for preparation of veneer from organic material like fruits and vegetables for surfaces such as furniture, decorative articles and the like.

[0033] DESCRIPTION OF THE INVENTION:

[0034] References in the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, characteristic, or function described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

[0035] References in the specification to “preferred embodiment” means that a particular feature, structure, characteristic, or function described in detail thereby omitting known constructions and functions for clear description of the present invention.

[0036] The foregoing description of specific embodiments of the present invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed and obviously many modifications and variations are possible in light of the above teaching.The fiber flats or surfaces from fruits and vegetables in accordance with the present invention are made as per the requirement of the texture and pattern. The fruit fibre surfaces are processed further with treatments including UV protection, PU coating and the like depending upon the application of the sheet.

[0037] In one aspect, the present invention discloses a process for preparation of vegetable or fruit surfaces.

[0038] In another aspect, the present invention describes a process of preparation of vegetable or fruit surface veneers.

[0039] Referring to FIG. 1, a process for the preparation of vegetable or fruit surfaces in accordance with the present invention is disclosed. Accordingly, the process (100) for preparation of vegetable or fruit fibre surfaces has a plurality of sequentially executed stages. Each stage is progressively transform organic plantbased material into a structurally stable, cohesive fibre surface capable of being used as a sheet, decorative panel, veneer substrate, lighting diffuser, or similar structural surface.

[0040] The present invention includes a multi-stage process for preparing vegetable or fruit fibre surfaces through controlled material transformation. The process includes sequential execution of: (i) Organic Substrate Sectioning (104); (ii) Microbial Stabilization Treatment (108); (iii) Chromatic Infusion Treatment (112); (iv) Hydrothermal Plasticization (116); (v) Thermal Shock Fixation (120); (vi) Structured Overlap Assembly (124); (vii) Progressive Compression Consolidation (128); and (viii) Controlled Desiccation and Fibre Bond Formation (132). These stages collectively enable binder-free fibre interlocking and sheet formation fromorganic slices through thermal conditioning, pressure-induced cellular collapse, and controlled dehydration, resulting in a cohesive, structurally stable, sustainable fibre surface suitable for decorative and structural applications.

[0041] In the initial stage of the process i.e. Organic Substrate Sectioning (104), organic plant-based material including fruits or vegetables is selected and prepared for structural transformation. The organic substrate is preferably selected from fruits or vegetables that are surplus, discarded, cosmetically imperfect, or otherwise unsuitable for conventional commercial sale, thereby promoting sustainability and waste reduction. However, the process is not limited thereto and may utilize fresh or processed plant material as required.

[0042] The selected organic material is washed and cleaned to remove surface contaminants and debris. Thereafter, the material is subjected to controlled sectioning to produce slices of predetermined thickness and orientation. The sectioning may be performed using manual slicers, semi-automatic slicers, automatic slicers, meat slicers, or specialized vegetable slicing equipment. The slicing orientation may be horizontal, vertical, diagonal, radial, or any other orientation depending upon the desired aesthetic, structural, or translucency characteristics of the final fibre surface.

[0043] In a preferred embodiment, the slice thickness is maintained within a range of approximately one-quarter inch to one inch. However, thinner or thicker slices may be utilized depending on the structural rigidity or light transmission characteristics required. In this stage uniformity in geometry, controlled exposureof cellular fibre structures, and pattern-defining configuration of the organic substrate are of utmost importance.

[0044] Following sectioning, Stage II includes Microbial Stabilization Treatment (108). This stage includes subjecting the slices to microbial stabilization treatment to inhibit biological degradation. The sliced substrates are immersed in a heated aqueous solution containing an antifungal or antimicrobial agent. The solution temperature is preferably maintained between approximately 80°C and 100°C.

[0045] In a preferred embodiment, about 15 to 30 grams of antifungal agent is dissolved in 7 to 8 litres of water. The slices are maintained in the solution for a duration of approximately 30 minutes to one hour. It is noted, however that Stage II (108) reduces fungal growth, prevents mold formation during drying, and advantageously enhances long-term stability and storage life of the resulting fibre surface.

[0046] Upon completion of microbial stabilization, Stage III includes Chromatic Infusion Treatment (112). This stage includes subjecting the stabilized slices to controlled colour enhancement or modification.

[0047] The slices are immersed in a dye solution prepared using either hot-water soluble dyes or cold-water soluble dyes. The dye concentration is preferably maintained within a range of approximately 1 to 20 grams per 7 to 8 litres of water. The immersion duration may range between approximately 10 minutes and 2 hours, leading to hydrothermal plasticization (116) depending upon the desired depth of colour penetration and uniformity. In embodiments employing hot-water dye, thesolution temperature may be maintained between 90°C and 100°C to promote effective chromatic infusion.

[0048] Chromatic Infusion Treatment (112) advantageously enables controlled penetration of colour into the cellular structure of the slices, enhances aesthetic characteristics, and stabilizes pigmentation. In certain embodiments, this stage may be omitted where preservation of natural colour is preferred.

[0049] Immediately following hydrothermal conditioning (116), Stage V includes the thermal shock fixation (120). This stage i.e. thermal shock fixation (120) includes rapidly cooling the thermally conditioned slices to stabilize the cellular structure. The slices are immersed in cold water maintained within a temperature range of approximately 5°C to 10°C for a duration of about 30 minutes to 2 hours.

[0050] The rapid temperature transition stabilizes the softened matrix, fixes infused colour within the cellular structure, and reduces the likelihood of pigment seepage. Replacement of coloured solution with clean water during this stage further prevents dye bleeding. Thermal Shock Fixation (120) enhances dimensional stability and prepares the slices for structural assembly.

[0051] Subsequent to stabilization, Stage VI includes Structured Overlap Assembly (124). This stage includes arranging the treated slices into a layered configuration designed to promote fibre interlocking and moisture extraction.

[0052] In this stage of Structured Overlap Assembly (124), a base absorption assembly is prepared, including layered newspaper stacks made of high GSM handmade paper, preferably around 500 GSM, followed by placement of a fabric layer such as cotton or PV fabric.The slices are arranged over the fabric in a partially overlapping configuration. The overlap pattern may be uniform, staggered, patterned, or mosaicbased depending on the desired structural density and translucency characteristics. A secondary absorption assembly is positioned above the arranged slices, forming a layered composite structure ready for compression. Structured Overlap Assembly (124) ensures continuous sheet formation, uniform load distribution during compression, and optimized fibre engagement between adjacent slices.

[0053] Following assembly, Stage VII includes Progressive Compression Consolidation (128). This stage (128) includes subjecting the layered composite structure to mechanical compression to extract moisture and induce fibre interlocking. The assembly is inserted into a mechanical compression device such as a handpress. Compression is applied in progressive cycles.

[0054] In a preferred embodiment the initial compression duration is approximately 4 to 6 hours; the secondary compression duration is approximately 8 hours; total compression cycles range from 5 to 6; Intervals between cycles range from 12 to 24 hours. Absorption layers may be periodically replaced to facilitate efficient moisture removal. A person skilled in the art will appreciate that the progressive compression consolidation advantageously causes collapse of cellular structures and promotes natural fibre-to-fibre bonding without the addition of synthetic adhesives or binding agents.

[0055] Finally, the Stage VIII includes Controlled Desiccation and Fibre Bond Formation (132). This stage (132) includes completing moisture removal under controlled pressure conditions to achieve structural consolidation. The compressedassembly is transferred to a controlled drying environment and positioned between corrugated sheets. Uniform weight is applied using wooden or rigid elements to maintain consistent pressure distribution.

[0056] Drying is preferably carried out for approximately 65 to 72 hours. During controlled desiccation, residual moisture is removed and fibre bonding is completed through pressure-induced cellular interlocking. The overlapping slices adhere to one another to form a cohesive, binder- free fibre surface. The resulting fibre surface exhibits structural stability, pattern retention, translucency characteristics where applicable, and suitability for decorative and structural applications.

[0057] The sequential execution of the above-described stages results in formation of a cohesive fibre surface derived directly from intact organic slices without conversion into pulp or incorporation of synthetic binders.

[0058] Conventional paper manufacturing typically requires mechanical or chemical pulping of wood fibres, followed by sheet formation through slurry deposition and pressing. Such processes involve significant fibre disintegration and removal of natural cellular architecture. In contrast, the present process retains the inherent macro-structure of the sliced organic substrate while inducing controlled cellular collapse and interlocking through hydrothermal plasticization and progressive compression consolidation.

[0059] During Stage IV of Hydrothermal Plasticization (116), controlled exposure to temperatures between 90°C and 100°C softens cell walls composed primarily of cellulose, hemicellulose, and pectin matrices. Subsequent Stage VII of Progressive Compression Consolidation (128) applies sustained mechanical pressure overmultiple cycles, resulting in deformation and interpenetration of adjacent cellular matrices. The moisture content of the slices is progressively reduced from an initial range typically exceeding 80-90% (wet basis) to a stabilized moisture content of approximately 5-12% after Stage VIII Controlled Desiccation and Fibre Bond Formation (132). This controlled reduction in moisture content enables fibre-to-fibre engagement without adhesive additives.

[0060] Comparatively, edible fruit leather processes generally involve pulping and sugar incorporation prior to dehydration, resulting in homogeneous films lacking structural fibre architecture. Decorative air-drying techniques, on the other hand, often produce brittle slices that remain discrete and do not exhibit cohesive interlocking behaviour. The present process, through structured overlap assembly and progressive compression, yields a continuous sheet exhibiting unified mechanical integrity.

[0061] In representative implementations, fibre sheets prepared using pineapple, apple, zucchini, tomato, and strawberry substrates demonstrated consistent sheet formation when overlapping was maintained between 15% and 40% of slice surface area. Sheets produced under compression cycles of 5 to 6 repetitions exhibited improved tensile stability compared to single-cycle compression, with visibly reduced delamination at edges.

[0062] Furthermore, colour fixation achieved during Stage V Thermal Shock Fixation (120) reduces pigment seepage during drying, enabling dimensional stability and pattern retention. In controlled observations, sheets subjected to rapidcooling at 5-10°C exhibited noticeably lower dye migration compared to sheets cooled gradually at ambient temperature.

[0063] The process of the present invention also permits scalable sheet dimensions. By proportionally increasing assembly area and maintaining uniform compression distribution, sheet sizes may be expanded from small format units (e.g., A4 dimensions) to larger decorative panels without fundamental alteration of the process sequence.

[0064] The resulting fibre surfaces exhibit cohesive structural formation achieved without the incorporation of synthetic binders or adhesive agents, the integrity of the sheet being derived from pressure-induced fibre interlocking. The natural orientation and macro-texture of the organic substrate are substantially retained, thereby preserving inherent visual patterns and fibre architecture.

[0065] Owing to the prior antimicrobial conditioning, the formed surfaces demonstrate reduced susceptibility to microbial degradation during storage and use. The translucency of the fibre surface may be controlled by regulating slice thickness and degree of overlap during assembly, thereby enabling variation in light transmission characteristics.

[0066] Further, the formed surfaces are compatible with secondary finishing treatments, including but not limited to ultraviolet protective coatings, oil finishes, polyurethane coatings, or resin encapsulation, depending upon the intended enduse application. By preserving the macro-structural geometry of organic slices while enabling cellular interlocking under controlled thermal and mechanicalconditioning, the process produces structurally unified surfaces from materials that would otherwise degrade, deform, or remain discrete upon simple dehydration.

[0067] In an embodiment of the present invention, the process (100) includes formation of dehydrated and compressed individual sections of organic substrates without any overlapping with other sections. The individual dehydrated sections allow the user to position the sections as per the user’s requirements and then apply a sealer to fix the sections in a certain position. This embodiment prevents damage to fibre surfaces and leads to a more flexible surface formation.

[0068] Now referring to FIG. 2, a preferred process for the preparation of vegetable or fruit sheet veneers, hereinafter referred to as veneer process (200) in accordance with another aspect of the present invention is disclosed. The veneer process (200) includes a multi-stage process for veneer preparation through controlled material transformation. The process includes sequential execution of various stages including: (i) Surface refinement and layer Deposition (204); (ii) Layering and Stacking (208); (iii) Lamination and resin impregnation (212) and (iv) End-stage processing (216).

[0069] In the initial stage of the process (200) i.e. Surface refinement and layer Deposition (204), abrasive methods such as sanding, buffing, brushing, tumbling or the like are applied onto a surface on to which veneer is to be applied. This surface is a core material such as but not limited to wood, paper mache, glass or acrylic, cloth, plywood, MDF (Medium Density Fibreboard) or the like.

[0070] Following the Stage I of Surface Refinement (204), the Stage II includes Layering and stacking (208). The Stage II (208) includes positioning individualsections of dehydrated slices of fruits or vegetable, obtained from the process (100) onto the core material. Further, each individual sections of the fruits or vegetables is adhered to the core material through a water-based adhesive in a decorative pattern or structure as required by the user. The water-based adhesives include but are not limited to polyvinyl- acetate emulsions, acrylic based emulsions, natural binders like starch or the like.

[0071] The Stage II (208) is followed by the Stage III of Lamination and Resin Impregnation (212). In the Stage III (212), a layer of epoxy resin is applied over the slices of fruit and vegetables and is left to cure for a predefined amount of time. Curing transforms the liquid resin into a rigid and stable three-dimensional polymer network.

[0072] The final Stage IV is a stage of end-stage processing (216). In Stage IV (216), the cured surface is buffed or sanded by hand or by mechanical means and treated with a solvent to achieve a clear surface, and finally with an oil finish. This type of veneering provides various patterned surfaces on articles such as furniture like sofas, table tops, cupboards and the like. Further, the veneer process (200) is also applied to articles such as lamps to form decorative surfaces.

[0073] In accordance with this aspect, in the Stage I Surface refinement and layer Deposition (204), the core material is wood, glass or acrylic or the like. The smoothening is carried out by conventional methods selected from diamond polishing, polishing burs, edge finishing, fine abrasives, ultrasonic polishing, ceramic glazing, composite polishing and the like. Preferably, 3 coats of the waterbased sealant are applied in Stage I (204). The water-based sealants or plant basedwood stains are selected from commercially available sealants including Rubio monocoat, PermaSeal (Ultradent Products, Inc.), OptiGuard (Kerr Dental), BisCover LV (BISCO, Inc.), G-Coat Plus (GC America, Inc.), Fortify (BISCO, Inc.) and the like.

[0074] In the Stage II (208), the water-based adhesive is selected from PVA (polyvinyl acetate) glue, contact cement (water based variants), urea formaldehyde glue (water-based), hide glue (liquid, waterbased), woodworking veneer glue (specialized water-based adhesives) and the like.

[0075] Further, in the Stage III (212), the epoxy resin for resin impregnation is selected from west system epoxy (105 resin with hardeners), system three epoxy, Haksons epoxy, TotalBoat epoxy resin, MAS epoxy, ProMarine clear table top epoxy, raka epoxy resin and the like. Finally, In the Stage IV (216), the core material is sanded with 120grit and 180grit sanding paper with a sanding machine, and more preferably 180grit sand paper. The solvent is selected from acetone and the like. The oil finish applied to the veneer is a hard wax, non-toxic, VOC- free, oil finish.

[0076] In an alternate embodiment, the process for preparing vegetable or fruit sheet veneer (200) includes repeating the steps of smoothening and coating (205), positioning dehydrated slices (210), epoxy layering (215) and finishing (220) to prepare a plurality of layers of veneer by allowing each layer to dry for a predefined time. The predefined time is selected from 1-2 hours.

[0077] In another embodiment, the process for preparing vegetable or fruit sheet veneer (200) includes incorporating thread of fabrics with the slices of fruit andvegetable to add additional strength to the veneer surface. The thread of fabric is selected from jute, embroidery thread, 3 / 4 / 6 strands, sisal threads, thinly cut paper strips and the like.

[0078] In another embodiment of the present invention, undulated fibre surfaces are prepared from the process (100). Undulated fibre surfaces are prepared by adhering individual dehydrated fruit or vegetable slices onto material such as paper mache. This material is then positioned on an undulated surface and is allowed to dry off. The resultant is an undulated surface that may be utilized for means of the user’ s requirement.

[0079] Referring to FIG. 3 A, a third embodiment of an automated fibre surface manufacturing and digital texture generation system (300) of the process (100) of the present invention is illustrated. The system (300) is configured to execute, in an integrated and coordinated manner, all process stages required for forming a cohesive fibre surface from sliced organic plant material, and further configured to generate a digital representation of the manufactured fibre sheet. The system (300) is arranged as a sequential production line extending from a raw material input region to a dual-output discharge region.

[0080] The system (300) includes a material receiving and feeding arrangement (304) configured to accept organic plant material selected from fruits, vegetables, or other plant-derived substrates. The feeding arrangement (304) regulates supply to a downstream automated slicing unit (308). The slicing unit (308) is configured to produce slices of controlled and adjustable thickness. The slice thickness may beselected based on desired translucency, fibre bonding characteristics, and final surface texture.

[0081] The sliced material is transferred through a plurality of treatment stations configured to execute conditioning operations. These stations may include an antimicrobial stabilization treatment region (312) configured to inhibit microbial growth and prevent degradation during downstream drying. An optional chromatic infusion region (316) may be provided to impart coloration or modify natural tonal characteristics. A hydrothermal conditioning region (320) is provided to soften cellular structures and increase flexibility of the slices. A thermal stabilization region (324) is further provided to reduce structural distortion and stabilize internal fibre orientation.

[0082] The treated slices are then transferred to a structured overlap assembly region (328). The overlap assembly (328) may be executed using programmable placement mechanisms including robotic arms, gantry systems, vacuum pick-and-place tools, or guided conveyors. The slices are arranged in a partially overlapping configuration to create a continuous surface architecture. Overlap ratio and placement orientation are selectable parameters.

[0083] Following structured arrangement, the overlapped assembly (328) is subjected to progressive compression. The compression arrangement (332) may include a hydraulic, pneumatic, or servo -driven press configured to apply one or more pressure cycles. Compression facilitates moisture removal and promotes natural fibre interlocking between adjacent slices. Moisture may be absorbed through intermediate absorption layers or extracted through mechanical expression.The compressed assembly (332) is subsequently transferred to a controlled drying chamber (336). The drying chamber (336) regulates temperature, airflow, and humidity to achieve gradual desiccation while maintaining dimensional stability. Controlled drying results in fibre bond formation without the necessity of synthetic binders. Upon completion of drying, a cohesive fibre sheet is produced.

[0084] Downstream of the drying region, the system (300) includes an inspection arrangement (340). The inspection arrangement (340) may include vision-based imaging and thickness measurement systems configured to assess surface uniformity, structural continuity, and defect presence.

[0085] The system (300) further includes a digital capture arrangement (344) positioned to optically scan each accepted fibre sheet. The captured image is processed by a digital processing unit (344) to generate a high-resolution digital texture file corresponding to the physical sheet. The digital output may be stored, transmitted, or used for subsequent printing onto substrates including textile, laminate, paper, or composite materials. Accordingly, the system (300) provides two coordinated outputs such as a physical fibre sheet output; and a digital texture file output corresponding to the physical sheet.

[0086] Referring now to FIG. 3B, the architecture of the system (300) is illustrated in block format. Raw material input is sequentially processed through slicing, stabilization, optional coloration, hydrothermal conditioning, thermal stabilization, structured overlap assembly, progressive compression, and controlled drying functions. The dried sheet proceeds to inspection and thereafter branches into physical output and digital capture functions.A central control unit governs operation of conveyors, fluid circulation systems, heating elements, cooling systems, compression mechanisms, robotic placement systems, inspection devices, and digital capture devices. Sensor feedback including temperature, pressure, humidity, moisture content, and positional data may be integrated into the control loop to ensure repeatability and process stability.

[0087] Referring to FIGS. 3 A and 3B, the present invention provides an system (300) to manufacture cohesive fibre sheets from sliced organic plant material and to generate a corresponding digital texture output. The system (300) includes a plurality of functional modules arranged sequentially along a controlled production line and operatively governed by a centralized control architecture.

[0088] In one embodiment, the system (300) includes a raw material feeding module (304) configured to receive organic plant material selected from fruits, vegetables, or other plant-based substrates. The feeding module (304) includes a loading hopper and a controlled feed mechanism configured to regulate the supply of material to a downstream slicing module. The feed mechanism (304) may include a belt conveyor, rotary feeder, push-actuated mechanism, or metered gravity chute. The feeding rate is synchronized with downstream processing capacity to ensure continuous and balanced throughput.

[0089] Downstream of the feeding module (304), the system (300) includes an automated slicing module (308) configured to convert the organic material into substantially planar slices of predetermined thickness. The slicing module (308) may include a rotary blade assembly, reciprocating cutter, band-blade slicer, orequivalent cutting mechanism. The thickness of the slices is adjustable either mechanically or through servo-controlled actuation. Controlled thickness is essential to regulate translucency, bonding behavior, and final sheet texture characteristics. The sliced material is transferred via conveyor to subsequent treatment modules.

[0090] Following slicing, the slices are introduced into a microbial stabilization module (312) configured to inhibit biological degradation. The stabilization module (312) includes a treatment tank containing an antimicrobial solution maintained at controlled temperature. The tank is equipped with circulation pumps and heating elements to ensure uniform solution distribution and thermal consistency. The slices remain immersed for a predetermined residence time sufficient to reduce microbial susceptibility and improve storage stability prior to drying.

[0091] In embodiments where aesthetic modification is desired, the system (300) further includes a chromatic infusion module (316) positioned downstream of the microbial stabilization module. The chromatic infusion module (316) includes a dye bath or infusion chamber configured to impart coloration to the slices. The dye concentration, immersion duration, and temperature are controlled to achieve uniform or patterned coloration depending on selected processing parameters.

[0092] Subsequent to coloration, the slices are transferred to a hydrothermal plasticization module (320). The hydrothermal module (320) exposes the slices to elevated temperature aqueous or steam-based treatment conditions. This stage softens plant cellular structures, increases pliability, and reduces brittleness.Controlled hydrothermal exposure improves conformability during subsequent overlap assembly and enhances fibre bonding potential during compression.

[0093] Immediately following hydrothermal treatment (320), the slices are subjected to thermal shock stabilization within a cooling module. The cooling module (324) includes a controlled cooling tank or chilled circulation system configured to rapidly reduce the temperature of the slices. Rapid cooling stabilizes internal fibre orientation, reduces thermal distortion, and assists in fixing infused coloration where applicable.

[0094] After completion of thermal conditioning (324), the slices are transferred to a structured overlap assembly module (328). The structured overlap module (328) includes a programmable placement mechanism such as a robotic arm, gantry system, or guided mechanical alignment platform. The placement mechanism (328a) arranges individual slices in a partially overlapping configuration on a support carrier or absorption substrate. The overlap ratio, orientation, and placement geometry are selectable parameters controlled through the systems (300) central controller. This stage establishes the continuous surface architecture that will define the final fibre sheet.

[0095] The overlapped assembly (328) is then transferred to a progressive compression module (332). The compression module (332) includes a press arrangement, which may be hydraulic, pneumatic, or servo-electric. The press applies controlled compression cycles to the overlapped assembly (328). During compression, moisture is expelled and fibre interfaces are brought into intimate contact. Mechanical interlocking occurs between adjacent slice boundaries, therebyinitiating consolidation. Compression parameters including force magnitude, dwell time, and cycle repetition are programmable.

[0096] Following compression, the partially consolidated assembly is introduced into a controlled drying module (336). The drying module (336) includes a chamber configured to regulate temperature, airflow, and humidity. The drying process is conducted under controlled environmental conditions to achieve gradual desiccation while maintaining dimensional stability and flatness. Controlled drying facilitates natural fibre bond formation without the use of synthetic binders, resulting in a cohesive fibre sheet.

[0097] Upon completion of drying, the formed fibre sheet is transferred to a quality inspection module (340). The inspection module (340) includes a vision-based imaging system configured to assess surface continuity, overlap uniformity, defect presence, and overall structural integrity. Additional measurement devices may evaluate sheet thickness and residual moisture content. Sheets satisfying predefined acceptance criteria proceed to output, while non-conforming sheets may be diverted.

[0098] In addition to physical sheet output, the system includes a digital capture and texture processing module (344). The digital capture module (344) includes a high-resolution scanner or imaging camera positioned to capture the surface texture of each accepted fibre sheet. Controlled illumination ensures accurate color and texture representation. The captured image data is processed by a computing unit to generate a digital texture file corresponding to the physical fibre surface. The digital file may be stored, transmitted, or utilized for printing on various substrates.The system (300) further includes a centralized control architecture comprising an industrial controller or programmable logic controller operatively connected to motion drives, conveyor motors, pumps, heating elements, cooling systems, robotic actuators, compression mechanisms, inspection devices, and digital imaging equipment. Sensor feedback including temperature, pressure, humidity, moisture content, slice thickness, and positional data is integrated into the control system to maintain synchronized operation across all modules.

[0099] In operation, organic plant material introduced into the feeding module is sequentially sliced, conditioned, assembled, compressed, dried, inspected, and digitally captured within a continuous automated workflow. The system (300) thereby produces two coordinated outputs: a cohesive fibre sheet and a corresponding digital texture representation derived from the same manufactured sheet.

[0100] Referring to FIG. 7 and 8, various results of the process (100) are described. FIG. 7 shows a fibre sheet made from tomatoes. The process (100) clearly retains the structure of the individual tomato slices along with the seeds and outer skin of the tomato. Further, FIG. 8 shows a strawberry fibre sheet made from the process (100). This fibre sheet is very recognizable to be made from strawberries as it retains the shape of strawberries and the individual seeds as well.

[0101] EXAMPLES

[0102] The following examples are provided to illustrate practical implementation of the process described herein. These examples are for explanatory purposes only and are not intended to limit the scope of the invention.Example 1: Preparation of Pineapple Fibre Surface Sheet

[0103] Referring to FIG. 4, pineapple fruit was used as the organic substrate for preparation of a fibre surface sheet.

[0104] Stage I - Organic Substrate Sectioning

[0105] Fresh pineapple was washed and sliced horizontally using a mechanical slicer. The thickness of the slices was maintained at approximately 6 mm (±1 mm). The initial moisture content of the slices was measured to be approximately 85-88% (wet basis).

[0106] Stage II - Microbial Stabilization Treatment

[0107] The sliced pineapple substrates were immersed in a heated aqueous solution comprising approximately 20 grams of sodium chloride dissolved in 8 litres of water. The temperature of the solution was maintained at approximately 95 °C. The slices were retained in the solution for approximately 45 minutes to allow adequate stabilization.

[0108] Stage III - Chromatic Infusion Treatment

[0109] Following stabilization, the slices were immersed in a hot-water dye solution prepared using approximately 10 grams of yellow dye dissolved in 7 litres of water maintained at approximately 90°C. The immersion was continued for approximately 60 minutes to achieve uniform colour penetration.

[0110] Stage IV - Hydrothermal Plasticization

[0111] The dyed slices were subjected to boiling at approximately 95°C for approximately 20 minutes to induce cellular softening and increase pliability.

[0112] Stage V - Thermal Shock FixationImmediately thereafter, the slices were transferred to cold water maintained at approximately 7 °C and retained therein for about 60 minutes. The coloured water was replaced with clean water once during this stage to prevent dye seepage. Stage VI - Structured Overlap Assembly

[0113] The treated slices were arranged over a cotton fabric layer positioned on a base absorption assembly comprising newspaper stacks and approximately 500 GSM handmade paper. The slices were overlapped by approximately 25-30% of their surface area to promote fibre engagement and continuous sheet formation. A secondary absorption assembly was positioned above the slices.

[0114] Stage VII - Progressive Compression Consolidation

[0115] The layered assembly was inserted into a handpress device. Compression was applied in five cycles, wherein the first cycle lasted approximately 5 hours and subsequent cycles lasted approximately 8 hours each, with approximately 12-hour intervals between cycles. The absorption layers were replaced after each compression cycle to facilitate moisture removal.

[0116] Stage VIII - Controlled Desiccation and Fibre Bond Formation

[0117] The compressed assembly was transferred to a drying arrangement between corrugated sheets under uniform wooden weight. Drying was continued for approximately 70 hours at ambient temperature of about 27-30°C.

[0118] Upon completion, the final fibre sheet exhibited a stabilized moisture content of approximately 8-10%, a thickness of approximately 3.5-4 mm, and cohesive structural integrity without visible delamination. No fungal growth was observed after storage for 30 days under ambient humidity conditions.Comparatively, pineapple slices subjected only to air drying without structured overlap and progressive compression did not form a cohesive sheet and exhibited brittle behaviour.

[0119] Example 2: Preparation of Apple Fibre Veneer Surface

[0120] Referring to FIG. 5, apple slices were processed and subsequently utilized for veneer application over a wooden substrate.

[0121] Stage I - Organic Substrate Sectioning

[0122] Fresh apples were washed and sliced vertically using a mechanical slicer to a thickness of approximately 5 mm. The initial moisture content of the slices was measured at approximately 82-85% (wet basis).

[0123] Stage II - Microbial Stabilization Treatment

[0124] The slices were immersed in an aqueous solution comprising approximately 18 grams of sodium chloride dissolved in 7 litres of water heated to approximately 90°C. The slices were maintained in the solution for approximately 40 minutes. Stage III - Chromatic Infusion Treatment

[0125] A red dye solution was prepared by dissolving approximately 12 grams of dye in 8 litres of water maintained at approximately 95°C. The slices were immersed in the dye solution for approximately 45 minutes to achieve desired colour enhancement.

[0126] Stage IV - Hydrothermal Plasticization

[0127] The slices were subjected to boiling at approximately 95°C for about 15 minutes to induce softening of the cellular matrix.

[0128] Stage V - Thermal Shock FixationThe slices were transferred immediately to cold water maintained at approximately 6°C and retained for approximately 45 minutes to stabilize colour and cellular structure.

[0129] Stage VI - Structured Overlap Assembly

[0130] For veneer preparation, the dehydrated slices were arranged in a minimally overlapping configuration (approximately 15% overlap) over a fabric layer positioned on an absorption assembly.

[0131] Stage VII - Progressive Compression Consolidation

[0132] The assembly underwent six compression cycles in a handpress, wherein the first cycle lasted approximately 6 hours and subsequent cycles lasted approximately 8 hours each, with approximately 24-hour intervals between cycles.

[0133] Stage VIII - Controlled Desiccation and Fibre Bond Formation

[0134] The compressed slices were dried under weighted pressure for approximately 72 hours. The final moisture content stabilized at approximately 7-9%.

[0135] Veneer Application

[0136] The dehydrated apple slices were adhered onto a pre- sealed medium-density fibreboard (MDF) substrate using a water-based adhesive. A clear epoxy resin layer of approximately 2 mm thickness was applied over the slices and allowed to cure for approximately 24 hours. The surface was subsequently sanded using 180-grit abrasive paper and finished with a hard wax oil coating.

[0137] The resulting veneer surface exhibited uniform adhesion, retention of natural fibre orientation and seed patterns, dimensional stability, and absence of dyemigration following resin encapsulation. No visible microbial growth was observed after 45 days of storage at approximately 65% relative humidity.

[0138] Comparatively, untreated apple slices adhered directly to a substrate without microbial stabilization developed visible fungal spots within approximately 10-12 days under similar environmental conditions.

[0139] Example 3: Preparation of Translucent Zucchini Fibre Sheet for Lighting Applications

[0140] Referring to FIG. 6, zucchini vegetable slices were processed to prepare a translucent fibre sheet suitable for decorative lighting applications.

[0141] Stage I - Organic Substrate Sectioning

[0142] Fresh zucchini was washed and sliced transversely using a mechanical slicer. The slice thickness was maintained at approximately 3 mm (±0.5 mm) to promote light transmission in the final sheet. The initial moisture content of the slices was measured to be approximately 90-92% (wet basis).

[0143] Stage II - Microbial Stabilization Treatment

[0144] The slices were immersed in a heated aqueous solution comprising approximately 22 grams of sodium chloride dissolved in 8 litres of water. The solution temperature was maintained at approximately 92°C. The slices were retained in the solution for approximately 50 minutes to ensure effective stabilization.

[0145] Stage III - Chromatic Infusion Treatment

[0146] For this example, no external dye was added in order to preserve the natural palegreen translucent appearance of the zucchini slices. Accordingly, Stage III wasperformed without dye immersion, and the natural pigmentation of the slices was retained.

[0147] Stage IV - Hydrothermal Plasticization

[0148] The slices were immersed in boiling water at approximately 95 °C for approximately 10 minutes to induce controlled softening of the cellular matrix while minimizing excessive structural collapse that could reduce translucency. Stage V - Thermal Shock Fixation

[0149] The thermally conditioned slices were immediately transferred to cold water maintained at approximately 6-8 °C and retained for approximately 40 minutes to stabilize cellular structure and prevent colour degradation.

[0150] Stage VI - Structured Overlap Assembly

[0151] The slices were arranged in a minimal overlap configuration, wherein adjacent slices overlapped by approximately 10-15% of their surface area to maximize light transmission while maintaining structural cohesion. The assembly was formed over a cotton fabric placed on a base absorption layer comprising 500 GSM handmade paper and newspaper stacks. A secondary absorption assembly was positioned above the slices.

[0152] Stage VII - Progressive Compression Consolidation

[0153] The layered structure was inserted into a handpress and subjected to four compression cycles:

[0154] • First cycle: approximately 4 hours

[0155] • Subsequent cycles: approximately 6 hours each

[0156] • Interval between cycles: approximately 12 hoursReduced compression duration compared to Example 1 was selected to preserve partial cellular translucency while achieving sufficient interlocking. Stage VIII - Controlled Desiccation and Fibre Bond Formation

[0157] The compressed assembly was dried between corrugated sheets under uniform wooden weight for approximately 68 hours at ambient temperature (approximately 26-29°C).

[0158] Upon completion, the final sheet exhibited a final moisture content of approximately 7-9% and an average sheet thickness of approximately 2-2.5 mm. Further, the final sheet had visible natural fibre pattern retention and uniform cohesion without separation of slices. Also, the translucent characteristics permitting measurable light transmission.

[0159] Light transmission testing was conducted using a 9-watt LED backlight positioned behind the sheet and demonstrated diffuse illumination with visible transmission of approximately 30-40% of incident light, depending on overlap density.

[0160] Comparatively, zucchini slices dried without structured overlap and progressive compression exhibited curling, brittleness, and non-uniform light diffusion, and did not form a continuous panel suitable for lighting applications.

[0161] The fibre sheet prepared in accordance with the present process was successfully integrated into a decorative lamp housing, demonstrating dimensional stability and absence of fungal growth after 30 days under indoor ambient conditions.These examples demonstrate practical implementation of the sequential stages and confirm the formation of cohesive fibre surfaces through controlled thermal conditioning, structured overlap assembly, progressive compression consolidation, and controlled desiccation.
