The Food Preservation using a Solar Dryer Monitoring System

High-moisture foods like mango, chili, meat etc., are not able to use long days because they are easily decomposed due to changing atmospheres. So the primitive peoples followed different methods to preserve the food and used it for a long time without poisoning. The sun dryer is the usual method to dry the food, but it will take more than one day. The food drying process is done with fossil fuels, but the increasing population is increasing the cost of the fuels. So, the food drying process needs an alternative method to dry the food. In this paper, the food is dried and preserved by solar energy. The overall processes are continuously monitored and preservation of the food by Arduino microcontroller with different sensors such as moisture sensor, LDR, Temperature sensor and cooling fans. The result of this work is better than other existing work and dried food at a low cost.
