Design and Construction of an IoT Solar Dryer for Semi-Dried Jerky

Abstract

This paper presents the design, construction of an IoT greenhouse solar dryer for semi-dried jerky. In the dryer, the heated air is controlled automatically by an IoT based system, and at the same time, the greenhouse absorbs solar energy directly through the polycarbonate transparent walls and roof. The results showed that the greenhouse solar dryer was a good dryer for semi-dried jerky. The semi-dried jerky after drying into the dryer was ensured for food safety with non-detected of total aerobic organisms, heavy metal, bacteria. The performance of the greenhouse solar dryer was test and temperature and humidity of drying process were collected through an IoT system.
