This invention is mainly used for drying paddy which is immediately after harvesting of the crop for, using this invention we can save lot of time than the conventional method of drying thereby reduce the human efforts for drying paddy and able to do unseasonal drying like rainy season and winter season.
Background of the Invention
Paddy rice is a staple crop that feeds millions of people worldwide, and its cultivation is a vital source of income for many farmers. However, the process of drying paddy rice after harvesting is a major challenge that affects its quality and marketability. The traditional method of drying paddy rice involves sun-drying or spreading it on a mat, which is not only time-consuming but also prone to spoilage due to unpredictable weather conditions, pests, and fungal growth. Moreover, manual methods are labor-intensive, and it requires significant human effort, which may be limited in some regions.
To overcome these challenges, researchers and innovators have explored various approaches to improve the paddy drying process. One such approach is the use of IoT technology to create an automated DE-moisturizer that removes excess moisture from paddy rice quickly and efficiently. The Paddy DE-moisturizer is designed to monitor the humidity and temperature inside the DE-moisturizer and adjust the position of the paddy rice using servo motors, ensuring uniform drying.
The invention of the Paddy De-Moisturizer is a significant breakthrough in the agricultural sector, as it provides a cost-effective and efficient solution to the challenges of paddy rice drying. The use of IoT technology enables farmers to automate the drying process, reducing the time and labor required to obtain high-quality dry paddy rice. The innovation has the potential to improve the income and livelihoods of small-scale farmers, enhance food security, and contribute to sustainable agriculture.
In conclusion, the invention of the Paddy De Moisturizer is a testament to the power of innovation and technology to solve some of the most pressing challenges facing humanity. By combining IoT technology with agricultural practices, we can create a more sustainable and resilient food system that benefits everyone.
The existing different types of drying methods which are used to dry paddy are , Field Drying - In many traditional harvesting systems farmers leave their harvested rice in the field for extended time because they are either waiting for the thresher or because they want to pre-dry the paddy. In this practice, often referred to as field drying, the rice plants are often stacked in piles with the panicles inside to protect them from rain, birds and rodents, a practice that can lead to massive heat build up inside the stacks. Sun drying -Sun drying is the traditional method for drying and is still preferred in Asia because of its low cost compared to mechanical drying. It requires little investment and is CO2 neutral since it uses the sun as heat source. Sun drying pavements have the advantage of high capacity and thus economics of scale and the drying operation can be partially mechanized. Usually manual tools are used for mixing and grain collection but larger mills often use two or four wheel tractors for this purpose. There is a significant capital requirement for the pavement and if cleanliness is not observed pollution with stones and dirt is common.
US4270280 Rice drying machine, The uniqueness of this invention lies in the temperature control units provided at each drying stage. These temperature control units regulate the burner or heat source to control the temperature of the air in each plenum. Each control unit includes two sensing rods made of aluminum with different configurations (solid or tubular) and a fabric wick surrounding the tubular rod. The rods expand and contract under different temperature conditions, providing an indication of the sensed temperature. The control units sense both the wet bulb temperature (measured by the tubular rod) and the dry bulb temperature (measured by the solid rod) in the plenums. By adjusting the position of the rods, the differential between wet bulb and dry bulb temperatures can be varied, allowing for precise control of the drying process. Additionally, the invention includes a control circuit and amplifier connected to the temperature control units. This control circuitry modulates the heat supplied by the burners based on the temperature differentials sensed by the control units, ensuring optimal drying conditions at each stage.

WO2004071166A3, Full heat moving heat grain dryer:-A grain dryer control system uses the grain dryer discharge temperature to account for moisture reduction in the grain as it cools after discharge from the dryer. The control system includes moisture and temperature sensors and a means to control the discharge of grain from the grain dryer. Given a grain discharge temperature, a control temperature and a moisture reduction factor as a function of temperature, the control system calculates an expected moisture reduction in the grain as the grain cools. Grain is discharged from the dryer when the target moisture content after cooling added to the expected moisture reduction in the grain as the grain cools meets the measured grain moisture content in the dryer.
