IoT Based Solar Energy Dryer

Abstract

Many developing and growing nations that are experiencing economic growth, postharvest loss of agriculture products is a big issue. On the one hand, there is an insufficient knowledge of the significant number of losses, and on the other side, there is insufficient information about the benefits of employing simple postharvest and conservation measures. Many countries waste a considerable amount of agricultural production. The introduction of proper postharvest technology could aid in the reduction of food waste. It also contributes to the increase of product quality, resulting in a high market price. Drying and storing freshly harvested cereals, fruits, and vegetables is the most common method of preserving them. Since ancient times, people have dried the commodities in the open sun; nevertheless, it is not without disadvantages, such as a high reliance on climatic conditions, sluggish drying rates, and the possibility of contamination, and so on. When employing mechanical dryers, these issues can be avoided; nevertheless, they consume a lot of energy. Simple solar-powered drying, in addition to mechanical treatments, can reduce the moisture content of vegies and fruits, allowing them to be stored for an extended period. Such a basic method has enormous promise, especially in regions where industrial preservation technologies are unavailable or inapplicable. The key objective is to run the entire system on clean and efficient energy like solar energy. The excess solar charge stored in the battery can be converted into AC to operate loads like lighting a bulb, especially in rural areas.
