Specification

Description:[0001] This invention relates to the field of agricultural engineering, more particularly to post-harvest grain management technologies. It involves the development of a renewable energy-powered, machine learning-driven modular grain drying system designed to reduce post-harvest losses in rural agricultural settings. The invention integrates solar and wind energy systems with automated control mechanisms to optimize drying conditions, ensuring uniform and efficient drying of grains while promoting sustainability and scalability. This invention addresses the critical need for energy-efficient, environmentally sustainable, and economically viable solutions to improve post-harvest grain quality, particularly in rural regions with limited access to conventional power sources and advanced agricultural infrastructure.

PRIOR ART AND PROBLEM TO BE SOLVED

[0002] Agricultural grain drying is an essential process for ensuring the preservation of harvested grains such as corn, wheat, and rice. Typically, grains are harvested with a high moisture content that needs to be reduced to safe levels to prevent spoilage, mold growth, and insect infestation during storage. Post-harvest grain losses are a pressing concern in India, particularly in rural areas where traditional drying methods such as sun drying are still prevalent. These methods, while inexpensive, are highly inefficient and lead to significant spoilage due to their dependence on favorable weather conditions. Grains spread on the ground for drying are frequently exposed to unpredictable elements such as rain, humidity, dust, and wind. Additionally, they are vulnerable to contamination from pests, birds, rodents, and microorganisms. This results in a substantial reduction in both the quantity and quality of the harvested grains, leading to economic losses for farmers.

[0003] For smallholder farmers, who comprise a large part of the agricultural community in rural India, the impact of post-harvest losses is particularly severe. Agriculture is often the primary source of income for these farmers, and any reduction in their crop yield directly affects their financial stability. Grains that are not properly dried are prone to moisture retention, making them susceptible to mold, fungal growth, and insect infestations. These issues not only degrade the nutritional value of the produce but also lower its market value, further straining the livelihoods of farmers who are already operating under tight economic constraints. This challenge calls for affordable, scalable, and energy-efficient solutions to improve the drying process, preserve grain quality, and enhance farmers' incomes.

[0004] The reliance on traditional sun drying methods presents a number of critical challenges. One of the main issues is the dependence on weather conditions. Sun drying is effective only during dry, sunny weather, and during the monsoon season or in areas with high humidity, it becomes difficult to achieve the necessary moisture levels to preserve grain quality. Grains are often left exposed to rain or high moisture in the air, which leads to spoilage. Moreover, sun drying exposes the grains to contamination, as they are typically spread on the ground. Dust, dirt, pests, birds, and rodents can all come into contact with the grains, resulting in a higher risk of contamination, which affects the safety and quality of the final product. In addition to contamination risks, sun drying can lead to inconsistent drying. When grains are unevenly exposed to the sun, some grains may retain moisture while others become adequately dried. This inconsistency makes the grains prone to microbial and fungal growth, increasing the likelihood of spoilage during storage. The process is also time-consuming, often taking several days to achieve the desired level of dryness. This prolonged exposure not only increases the risk of spoilage but also demands significant labor, as farmers must frequently monitor the drying process and protect the grains from sudden changes in weather or attacks from animals. These inefficiencies highlight the need for more reliable and less labor-intensive drying techniques that can ensure quality and consistency.
[0005] Several technological solutions have been developed in an attempt to mitigate post-harvest losses by improving the efficiency and reliability of grain drying.
Mechanical grain dryers are one such solution, using heated air to remove moisture from the grains in a controlled environment. These systems are highly efficient and provide consistent results, significantly reducing drying times compared to traditional methods. However, mechanical dryers come with several drawbacks. They are expensive to purchase and operate, particularly in rural areas where access to electricity or fuel may be limited. The high initial investment and ongoing operational costs put these dryers beyond the reach of smallholder farmers, who often cannot afford such technologies. Furthermore, mechanical dryers require specialized knowledge to operate, which presents an additional barrier to their widespread adoption in rural settings.

[0006] To resolve the above mentioned problem the renewable energy-powered grain drying system is designed to address post-harvest losses by leveraging solar and wind energy to power its operation. Designed for rural agricultural environments, it replaces traditional drying methods that often result in moisture retention, spoilage, and contamination. This system integrates automated control systems, allowing machine learning to manage temperature and humidity, ensuring consistent and uniform drying. Its modular design allows farmers to scale the system based on their needs, whether they operate a small farm or a larger cooperative. By utilizing renewable energy, the system not only reduces operational costs but also contributes to environmentally sustainable agricultural practices, improving farmers' income and grain quality.

THE OBJECTIVES OF THE INVENTION:

[0007] It has already been proposed that while various technologies have been developed to improve grain drying, they all present significant challenges that limit their effectiveness and adoption in rural areas. Cost is one of the primary barriers to the widespread use of mechanical and hybrid dryers. These systems, while efficient, are too expensive for most smallholder farmers. The upfront investment required for purchasing these systems, combined with their operational and maintenance costs, makes them inaccessible to the majority of rural farming communities. For farmers operating on tight margins, such expenditures are simply not feasible, even if the long-term benefits of reduced post-harvest losses are clear.Energy dependence is another significant issue. Many mechanical and hybrid dryers rely on electricity or fuel to operate, which can be inconsistent or unavailable in rural areas. Even solar dryers, which aim to be energy-efficient, still depend on sufficient sunlight to function effectively. In areas with frequent rain or cloud cover, these systems are unreliable. Furthermore, advanced drying technologies often require specialized knowledge to operate and maintain. Rural farmers, who may not have access to technical training or support, find it difficult to adopt these systems, particularly if they require regular maintenance or troubleshooting. This lack of operational knowledge limits the widespread adoption of such technologies.

[0008] The principal objective of the invention is to design, develop, and implement a renewable energy-powered, machine learning-driven, modular grain drying system that integrates solar panels and wind turbines to harness renewable energy. The system utilizes automated precision control of temperature and humidity, enabled by advanced sensors and machine learning algorithms, to mitigate post-harvest losses in rural agricultural settings. The system is intended to optimize energy efficiency, reduce dependency on fossil fuels, and ensure uniform drying conditions to preserve grain quality, prevent spoilage, and minimize contamination during the drying process.

[0009] Another objective of the invention is to utilize solar and wind energy as the primary power sources for the grain drying system, minimizing reliance on traditional energy sources such as grid electricity or diesel-powered machinery. This objective focuses on the strategic deployment of photovoltaic panels and wind turbines, ensuring the system operates in energy-scarce rural environments with low operational costs and enhanced sustainability.

[0010] The further objective of the invention is to implement a machine learning-driven automated control system that monitors and adjusts drying parameters, including temperature and humidity, in real-time. This feature ensures that grains are dried uniformly and optimally, mitigating risks associated with under-drying or over-drying, thereby preserving grain quality. The automated system minimizes the need for manual intervention, improving efficiency and reducing labor costs.

[0011] The further objective of the invention is a modular architecture that allows scalability to meet the varying capacity requirements of small-scale farmers and larger agricultural cooperatives. The modular design facilitates easy customization and expansion, enabling users to adjust the system's capacity to suit specific operational needs, making the system adaptable for a wide range of rural agricultural settings.

[0012] The further objective of the invention is to significantly reduce the environmental impact of grain drying by incorporating renewable energy and minimizing the use of conventional fuel sources. This objective includes promoting long-term sustainability in agricultural practices through the reduced carbon footprint of the drying process and the extended lifespan of the system due to low-maintenance requirements and reduced wear.

[0013] The further objective of the invention is to provide an economically viable grain drying solution that is affordable and accessible to rural farmers. By reducing operational costs through renewable energy and automation, the system aims to improve the financial outcomes for farmers by reducing grain spoilage, enhancing grain quality, and increasing marketability, thereby boosting income and promoting widespread adoption in underserved rural regions.

SUMMARY OF THE INVENTION

[0014] Solar grain dryers have been introduced as a more affordable and energy-efficient alternative to mechanical dryers. These systems use solar energy to heat air within an enclosed space, offering protection from contamination while still achieving uniform drying. While they address some of the issues associated with traditional sun drying, solar dryers still depend heavily on weather conditions. During cloudy or rainy periods, these systems become inefficient, and their performance can be unpredictable. Additionally, solar dryers often require significant space for installation, making them impractical for small farms that lack sufficient land area. Hybrid dryers, which combine solar energy with auxiliary heating from electricity or biomass, have also been developed to address the limitations of solar-only systems. These dryers ensure consistent drying even in unfavorable weather conditions. However, the complexity and cost of hybrid systems remain significant challenges. They require both initial capital investment and ongoing maintenance, which can be burdensome for small-scale farmers. The dual-energy design further complicates their operation, making it difficult for farmers to adopt without technical training and support. Finally, low-cost solutions such as polyethylene tunnels have been explored, providing a protective environment for grains during drying. However, these tunnels also rely on favorable sunlight and can lead to uneven drying if air circulation is not managed properly.

[0015] So here in this invention grain drying system harnesses renewable energy, using solar panels and wind turbines to address rural post-harvest grain losses. Traditional methods, like sun drying, often cause significant losses due to inefficiency, contamination, and weather exposure. The system combines conduction and convection drying techniques, regulated by a machine learning-based control system that monitors temperature and humidity to ensure uniform drying. This automation minimizes labor and reduces grain spoilage, thus enhancing quality and increasing farmers' profitability. The system's modular structure enables scalability, catering to both small-scale individual farms and larger cooperatives. Economically viable due to its reliance on renewable energy, it significantly reduces operational costs, contributing to sustainable agricultural practices. The system promotes long-term savings for farmers, with fewer maintenance needs and an extended equipment lifespan, further ensuring economic and environmental benefits.

[0025] The system's purpose extends beyond mere functionality, aiming to improve the livelihoods of rural farmers by providing a technologically advanced solution that is both accessible and economically sustainable. The reduction in post-harvest losses directly contributes to increased income for farmers, as the system preserves a higher proportion of their harvests, allowing them to sell more and at higher quality standards. Furthermore, by reducing manual labour requirements through automation, the system enhances productivity, offering a dual benefit of time savings and labour cost reduction.

[0026] The grain drying system offers a comprehensive solution to the challenges of post-harvest grain management in rural settings, integrating renewable energy, machine learning, and modular scalability. Its purpose and use are fundamentally aimed at enhancing agricultural productivity, reducing environmental impact, and improving the economic outcomes for rural farmers while offering a cutting-edge technological approach to a long-standing agricultural problem.

[0027] Here, the external appearance of the grain drying system developed as part of this invention is deliberately engineered to embody both functionality and durability while maintaining an aesthetic that resonates with its rural and agricultural environment. The system is housed within a robust, weather-resistant structure designed to withstand the diverse and often harsh climatic conditions typical of rural settings. The outer casing is constructed from materials that are not only resilient but also chosen for their sustainability, aligning with the system's overall purpose of promoting environmental responsibility.

[0028] Visually, the system features a streamlined and modular design, with a form that emphasizes simplicity and ease of integration into existing agricultural operations. The primary drying chamber forms the system's core and is enclosed within a smooth, insulated exterior. The system's surface is treated with a corrosion-resistant finish, ensuring longevity and reducing the need for frequent maintenance. The top of the unit is characterized by its integration of solar panels, positioned at an optimal angle to maximize solar energy capture throughout the day. These panels are seamlessly embedded into the structure, ensuring they do not obstruct the system's functionality while maintaining a visually cohesive design.

[0029] Adjacent to the solar panels, wind turbines are positioned on strategically designed mounts, allowing them to harness wind energy efficiently. These turbines are engineered to blend into the system's overall form, minimizing any visual bulk while ensuring that they remain unobtrusive yet effective. Their placement is meticulously calculated to ensure that they do not interfere with the solar panels or other components, optimizing the dual-energy harvesting capabilities of the system.

[0030] On the front of the system, a user interface is discreetly integrated into the structure, providing users with a control panel that is both intuitive and user-friendly. A weatherproof cover protects This control interface, ensuring it remains functional in various environmental conditions. The interface is equipped with an LCD display allowing users to monitor critical drying parameters, such as temperature, humidity, and energy usage. The controls are designed to be accessible, with large, tactile buttons that facilitate ease of use, even for operators unfamiliar with advanced technology.

[0031] The system's modular nature is reflected in its external design, with clearly defined segments that can be added or removed depending on the capacity requirements of the user. The system is designed to occupy minimal space relative to its functionality, ensuring that it can be easily accommodated in various rural farm settings, regardless of available land area.

The system's external design also features passive ventilation grilles, carefully integrated into the structure to promote airflow without detracting from the overall visual simplicity.

[0032] The entire apparatus is finished in neutral, earth-toned colours that blend into the rural landscape, reducing visual disruption and harmonizing with its surroundings. This choice of colour improves its aesthetic appeal and reflects its purpose of unobtrusively serving rural communities. The external design is a deliberate balance between practicality and appearance, ensuring that while the system is technologically advanced, it remains approachable and easy to adopt for farmers with varying degrees of technological familiarity.

[0033] Overall, the system's exterior is a refined combination of functionality, durability, and aesthetic coherence, carefully designed to serve its purpose while being adaptable to the unique conditions of rural agricultural environments. The system's visual and structural features are aligned with its core objectives of sustainability, modularity, and ease of use, ensuring that it remains a practical yet sophisticated solution to the issue of post-harvest grain drying.

[0034] The grain drying system, as conceptualized, consists of a meticulously integrated set of components, each performing distinct yet complementary roles to achieve the overarching objective of reducing post-harvest losses through renewable energy-powered, machine learning-driven automation. The interplay between these components ensures a seamless, energy-efficient operation that leverages solar and wind energy alongside advanced control mechanisms to achieve optimal drying conditions for grains in rural settings. The system's components are designed for their individual functions and their capacity to interact harmoniously, forming a cohesive, automated drying solution that addresses the unique challenges faced in post-harvest management.

[0035] At the core of the system are the energy-harnessing mechanisms: the solar panels and wind turbines. These components form the foundation of the system's energy independence, drawing power from two of the most abundant renewable sources in rural agricultural regions. The solar panels, strategically positioned at optimal angles on the system's exterior, convert sunlight into electrical energy stored in an integrated battery system. Simultaneously, the wind turbines are mounted on unobtrusive yet efficient vertical structures designed to capture wind energy under varying conditions. These turbines convert kinetic energy from wind into electrical power, which is likewise stored within the same battery system. The dual energy sources ensure that the system remains functional regardless of daily weather fluctuations, maintaining energy availability for uninterrupted operation.

[0036] The electrical power generated by these renewable energy sources is distributed through the system's central power management unit, which regulates the flow of electricity to various components based on operational demand. This unit manages the energy supply to ensure that critical components, such as sensors, heating elements, and control systems, receive consistent and reliable power. By efficiently allocating energy resources, the power management unit ensures that the system maintains optimal performance while minimizing energy waste, thus contributing to the overall sustainability and cost-efficiency of the system.

[0037] The drying chamber is where the primary function of the system takes place. A combination of convection and conduction-based heating elements inside the chamber generates the necessary heat to dry the grains. The convection process ensures the circulation of heated air while the conduction elements directly transfer heat to the grains. This dual-method heating ensures that the grains are uniformly dried, preventing uneven moisture retention, which can lead to spoilage. The drying chamber itself is insulated to prevent heat loss, maximizing the drying process's efficiency and reducing the energy required to maintain optimal drying conditions.

[0038] Embedded within the drying chamber are highly sensitive temperature and humidity sensors. These sensors continuously monitor the environmental conditions inside the chamber, feeding real-time data to the machine learning-driven control system. The sensors' data collection is critical to ensuring that the drying process remains within the specified parameters necessary for preserving grain quality. Should the temperature or humidity deviate from the optimal range, the control system automatically adjusts the heating or ventilation system to correct the imbalance. This level of precision is achieved by integrating machine learning algorithms that analyze the data and predict the necessary adjustments to maintain consistent drying conditions, even under changing environmental variables.

[0039] The machine learning-driven control system serves as the entire operation's brain. This component processes the data received from the sensors, using predictive models to determine the optimal drying parameters based on real-time and historical data. The control system dynamically adjusts the drying conditions, such as altering the intensity of the heating elements or modulating the airflow within the chamber, to ensure that the grains are dried uniformly and efficiently. Additionally, the control system minimizes human intervention by automating the entire drying process, thereby reducing labour costs and the potential for human error. This intelligent automation is particularly beneficial in rural settings, where access to skilled labour and technical expertise may be limited.

[0040] Another critical component is the modular framework of the system. The drying chamber and its associated components are designed modularly, allowing users to add or remove sections of the system depending on their capacity requirements. This modularity ensures that the system can be scaled to accommodate the needs of small-scale farmers and larger agricultural cooperatives. Each module functions independently while integrated into the larger system, enabling seamless scalability without compromising performance. The modular design also simplifies maintenance, as individual sections can be serviced or replaced without requiring the entire system to be dismantled.

[0041] Ventilation is another integral part of the system, as it plays a key role in maintaining the airflow necessary for drying. The ventilation system has fans and ducts that circulate air through the drying chamber, ensuring moisture is efficiently removed from the grains. The ventilation system works in concert with the heating elements and the sensors, modulating the airflow based on real-time data provided by the control system. This ensures that the drying process is energy-efficient and effective in maintaining grain quality.

[0042] Although secondary to the automated controls, the system also includes a user interface, which allows for manual monitoring and adjustments when necessary. The interface provides the user with access to real-time data on the drying process, including temperature, humidity, and energy consumption. It also allows users to override the automated settings if specific conditions require manual intervention. The interface is designed to be user-friendly and accessible, ensuring that it can be operated by individuals with limited technical expertise.

[0043] The components of the system-including the solar panels, wind turbines, power management unit, heating elements, sensors, control system, ventilation system, and modular framework-work in tandem to provide a highly efficient, automated grain drying solution. Each component fulfils a distinct function that contributes to the system's overall purpose of reducing post-harvest grain losses in rural agricultural settings. Through precise integration and real-time data interaction, the system ensures that the drying process is both energy-efficient and highly effective, preserving grain quality and minimizing spoilage while promoting sustainability and economic viability for rural farmers.

[0044] The working of the renewable energy-powered, machine learning-driven modular grain drying system is a meticulously coordinated process involving multiple components, each performing distinct but interconnected functions to achieve optimal grain drying efficiency while minimizing post-harvest losses. The system operates in an automated manner, driven by a control unit powered by machine learning algorithms that adjust the system's behavior based on real-time environmental data and predefined parameters.

[0045] The operation begins with the collection and conversion of renewable energy. Solar panels, strategically positioned on the system's surface, capture sunlight and convert it into electrical energy through photovoltaic processes. Simultaneously, wind turbines harness kinetic energy from wind currents and convert it into additional electrical power. Both energy sources feed into a central battery storage system, ensuring that the system has a consistent and reliable energy supply, even during periods of low sunlight or wind. This dual-energy harvesting approach ensures that the system remains operational in diverse weather conditions, particularly in rural agricultural settings where access to conventional power sources may be limited or unreliable.

[0046] Once the system is powered, the grain drying process is initiated by loading the grains into the insulated drying chamber. The drying chamber is equipped with conduction and convection-based heating elements that work in unison to generate and circulate heat throughout the chamber. The conduction elements directly transfer heat to the grains, while the convection system ensures hot air circulation, facilitating uniform drying. The heating process is regulated by a series of sensors placed strategically within the chamber, continuously monitoring the temperature and humidity levels.

[0047] The sensors transmit real-time data to the system's central control unit, driven by machine learning algorithms. These algorithms analyze the incoming data, comparing it against optimal drying parameters that have been preconfigured or learned through historical data patterns. The control unit processes this data and makes real-time adjustments to the heating elements and ventilation system, ensuring that the temperature and humidity remain within the optimal range for grain drying. If the system detects deviations-such as excessive moisture or insufficient heat-the control unit automatically modulates the intensity of the heat or adjusts the airflow, ensuring the drying process is consistently effective.

[0048] During drying, the ventilation system plays a crucial role in maintaining the airflow necessary to remove moisture from the grains. The system's fans and air ducts are designed to circulate air efficiently through the drying chamber, promoting the evaporation of moisture while maintaining the desired internal temperature. The ventilation is also regulated by the control unit, which adjusts the airflow based on the humidity data provided by the sensors, ensuring the grains are neither over-dried nor under-dried.

[0049] The system's modular design allows for scalability, meaning that as the drying process is ongoing, additional drying chambers can be integrated or removed depending on the user's required operational capacity. Each module operates independently but is interconnected with the central control system, allowing for seamless operation regardless of the system's scale. This modularity is particularly advantageous in agricultural settings with varying harvest sizes, as it allows the system to be adapted to meet specific demands without compromising efficiency.

[0050] The user can monitor the process throughout the drying cycle via the user interface, which provides real-time data on temperature, humidity, energy usage, and drying progress. Although the system is designed to operate autonomously, the user can intervene manually if necessary, adjusting parameters via the interface to accommodate specific conditions or preferences. The interface is designed to be intuitive and accessible, ensuring that even operators with minimal technical expertise can manage the system effectively.

[0051] Upon completion of the drying process, the system automatically reduces the heating and ventilation activity, transitioning into a standby mode that conserves energy. Having been uniformly dried to the desired moisture level, the grains are ready for unloading and further processing or storage. The automated nature of the system ensures that the drying process is efficient and consistent, reducing the likelihood of grain spoilage due to under-drying or over-drying.

[0052] In conclusion, the working of this system represents a harmonious integration of renewable energy harvesting, machine learning-driven automation, and modular design. The various components work together in a seamless, automated manner to ensure that grains are dried efficiently, preserving their quality while reducing the operational costs associated with traditional grain drying methods. By leveraging renewable energy and advanced control systems, the invention provides a sustainable and economically viable solution to post-harvest grain losses in rural agricultural settings.

[0053] Case Study Example: In a rural farming community in Maharashtra, India, post-harvest grain losses had become a persistent issue, with farmers regularly experiencing up to 20% of their harvest spoiled due to moisture retention and contamination during the drying process. The farmers had been relying on traditional sun drying methods, which were highly dependent on weather conditions and lacked precision in controlling temperature and humidity, leading to inconsistent results and significant economic losses. Seeking a solution that would improve both efficiency and grain quality, the farmers decided to implement the renewable energy-powered, machine learning-driven modular grain drying system.

[0054] After installation, the system was configured to operate on a mix of solar and wind energy, taking advantage of the region's abundant sunlight and occasional wind. The farmers loaded their grains into the system's drying chamber, which automatically began the drying process, powered by renewable energy. The machine learning-driven control unit continuously monitored the environmental conditions within the chamber, adjusting the temperature and humidity levels based on real-time data from the sensors. The system's automated precision control ensured that the grains were dried uniformly, without the risk of under-drying or over-drying.

[0055] Midway through the drying process, a period of overcast weather resulted in a significant reduction in solar energy. However, the wind turbines continued to generate sufficient power, and the system seamlessly transitioned to wind energy, ensuring uninterrupted operation. The control unit adjusted the drying conditions accordingly, maintaining optimal temperature and humidity levels despite the changing external environment. This adaptability eliminated the reliance on weather conditions that had previously plagued the farmers using traditional drying methods.

[0056] Upon completion of the drying cycle, the grains were found to be consistently dried to the desired moisture level, free from spoilage or contamination. The system's automated control not only reduced the labor required for manual monitoring but also improved the overall quality of the grains, which fetched higher prices at the local market. The modular design of the system allowed the farmers to scale up during peak harvest seasons, easily adding additional drying chambers to meet their increased capacity needs.

[0057] As a result of implementing the system, the farming community experienced a significant reduction in post-harvest losses, from 20% to less than 5%. The economic impact was substantial, with farmers reporting a marked increase in income due to the higher quality and quantity of grains preserved during the drying process. Furthermore, the system's reliance on renewable energy drastically reduced operational costs, making it an economically viable and environmentally sustainable solution for the community.
