Solar Dryer Dengan Air Heater Berbasis Mikrokontroler Untuk Hasil Laut

Abstract

Food processing by drying method is done commonly, especially for fish and squid. In this way, dried fish and squid can durable through heating. Heating can decrease the water content, so it can inhibit bacterial growth. Now, people are still dry using traditional way to dry seafood under the sun, but this way is very dependent on the weather, so drying takes a long time. This research will discuss about inovation of solar dryer system that working by maximizing the absorption of solar heat and channeling heat, and then drying evenly using fan and motor to replace the object side to be dried, and additional air heater will be used if solar heat is not maximal. In additional, the tool also features a load cell sensor to scale the object of drying, as well as a microcontroller system to control the solar dryer and air heater. Finally, the results of this research show that’s a decreasing in water content 98% faster with drying temperature 60 ◦C, so it can help community productivity in managing seafood.
