Perancangan Perangkat Pengering Ikan Otomatis Skala Mini
Water content is the water content contained in the material and expressed in units of percent. Water content can affect the texture of fish and cause the development of bacteria in fish. In general, people only know the process of drying fish by looking at the texture of the fish while the water content found in fish is in accordance with the Indonesian National Standard (SNI), which is 40%. The purpose of drying fish is by controlling the water content so that the fish can be dried in accordance with the Indonesian National Standard (SNI). The control system contained in this device uses a DS18B20 temperature sensor, loadcell sensor, relay, heating element, and cooling fan. The working principle of this device uses a heating element to reduce the water content or load on the fish and the cooling fan to remove the hot temperature from the cabinet which is controlled by a relay to regulate the temperature. The heater will be active when the temperature is less than 60°C and the cooling fan is not active, when the temperature is more than 60°C. The device will automatically stop the heater when the load value is smaller or equal to the value of the set point. Reduction of water content up to 40% according to the Indonesian National Standard (SNI) with a 250g fish load takes 1 hour 43 minutes, a 500g fish load for 3 hours 17 minutes, and a 1000kg fish load for 6 hours 25 minutes.
