IOT Based Smart Food Dryer

The solar drying system utilizes solar energy to heat up air and to dry any food substance loaded, which is not only beneficial in that it reduces wastage of agricultural produce and helps in preservation of agricultural produce, but it also makes transportation of such dried produce easy and promotes the health and welfare of the people. This paper presents the design and construction of a domestic passive solar food dryer. The dryer is composed of solar collector (air heater) and a drying chamber containing fruits and vegitables trays both being integrated together. The air allowed in through air inlet is heated up in the solar collector and heaters through the drying chamber where it is utilized in drying (removing the moisture content from the food substance or agricultural produce loaded). The design was based on the hybrid system. which is more reliable system is obtained for proper design specification. Locally available materials were used for the construction, iron body of container(painted), inlet and outlet fans (air ventilation system), mild steel metal sheet and net trays for wastage.
