Solar Vegetable Dryer: A Sustainable Approach Towards Green Economy Shubham Bhimrao Bangar ---------------------------------------------------------------------***------------------------------------------------------------------ABSTRACT: India is one of the significantly making countries in the world and it has the second-largest agricultural source of wage, which covers 61% of the entire wage of the country. The most valuable pay bunch, by giving the fitting planning in this advancement, will make their whole nation to finished up one of the most significantly making areas in the world. In afterward a long time, numerous making made, and youthful countries stand up to insufficiencies of, characteristic items and vegetables due to typical catastrophes like seismic tremors, downpour, and any other unforeseen events. Presently the essential issue of this paper is to ensure the food things from post-harvest to customer level, which cover 60% of incidents due to the detachment of added substance methodologies. This paper fundamentally centred on the conventional techniques to advanced sun-oriented drying propels for perseverating, characteristic items, and vegetables. In India, generally 80 per cent of agriculturists are destitute, negligible creators. Among the challenges they go up against are fluctuating exhibit costs. A tomato can offer for 80 Rs per kg one month and as it were 20 Rs per kg one month a while later. Be that as it may, ranchers are not able to secure their nourishment for more than 1 to 2 weeks since of control costs, down and out establishment and require of financing to contribute in capacity workplaces. When the promote costs are moo, farmers regularly have to hurl missing their make, coming around in essential misuse. The coming about commitment without a doubt leads a few famers to commit suicide. To handle this issue, I have come up with cost effective sun-based dryer. The machine costs very less, as it is made completely from bamboo, thus bamboo can be created in farms and engages agriculturists to get dried out their country things and direct them for a slightest of six months, whereas ensuring supplements, colour and test.
INTRODUCTION: Drying has long been utilized as a method to extend the shelf life of food products, dating back to ancient times. Harnessing the sun's heat and wind, this age-old technique remains a cornerstone of food preservation. However, its energy-intensive nature, coupled with the increasing scarcity and cost of fossil fuels, has spurred a shift towards renewable energy sources. Among these, solar energy stands out for its environmental friendliness and minimal ecological footprint. Various types of solar dryers have been developed and tested across different regions, primarily falling into two categories: natural convection and forced convection. Natural convection dryers rely on buoyancy-induced airflow, while forced convection dryers employ fans, typically powered by electricity, solar modules, or even fossil fuels. Solar thermal technology, rapidly gaining traction in agricultural applications, offers distinct advantages over other alternatives like wind or shale. Abundant, inexhaustible, and clean, solar energy presents a sustainable solution for food preservation needs. Addressing the pressing issue of agricultural produce preservation, particularly in developing countries, holds significant importance. Inadequate infrastructure, limited processing capacities, and market challenges contribute to substantial post-harvest losses, exacerbating food security concerns. Drying emerges as a viable solution, not only curbing spoilage but also bolstering income opportunities and supply stability.[1] At the farm level, drying immediately post-harvest, especially during peak harvest periods, helps manage surpluses and extends storage capabilities. Thermal energy-based drying facilitates longer shelf lives and easier transportation by reducing moisture content. Moreover, when executed correctly, drying preserves nutritional quality and inhibits the proliferation of harmful pathogens. While energy-intensive, drying efficiency hinges on several factors such as produce type, size, arrangement on drying racks, and frequency of rotation. Optimal drying necessitates avoiding overcrowding and ensuring regular turning to achieve uniform drying.
Literature Review: Crop drying is a vital process in agriculture, aimed at reducing moisture content to ensure safe processing and prolonged storage of produce. It is estimated that a significant portion of global vegetable production—about 20%—is lost postharvest due to inadequate handling and suboptimal postharvest technology implementation. Typically, vegetables and
