Automatic Solar Tracking Based Food Dehydrator

Abstract

To combat the rise in losses, numerous operating processes for food preservation, including drying and cold storage, have been developed throughout the years. There are numerous sustainable and time-consuming methods for food preservation. Solar drying is one of the greatest in this situation. This paper presents about the solar dehydrator that is extremely useful for the farmers to save their crop.The use of solar energy as a drying system alternative produces better results at a very low cost of energy. In the case of drying applications, it is necessary to develop solar systems to achieve sustainable development. We also spotlight the environmental influence on solar energy that plays a prime role in the solar drying sector. Drying is an intricate process involving mass and heat transfer. In contemplation to improve the quality, the natural sun drying is incongruous and we must seek a substitute. Dehydrator is proposed to optimize the drying procedure and fasten the process. The application of solar tracking is used due to the responsiveness, reliability and stability. Solar tracking is used to make the best use of solar energy that is free to collect and convert this energy. According to product evaluations, the physical characteristics, flavour, and vitamin A and C preservation of solar-dried foods were typically on par with or better than those of traditional dried foods. With the exception of grain drying, the economics of solar systems show that the majority of drying techniques are only practical for use in small-scale operations. To pacify the post-harvest losses in agriculture and horticulture, the solar dehydrator is a strategical approach for rescuing the crops and farmers thus generating a source of income utilising the renewable source of energy.
