Rancang Bangun Alat Pengering Pakan Ikan Dengan Sistem Pemanas Konveksi Paksa
The natural drying proses that is required to dry pellet fish have some shortages, such as : a
long time and need some time reversal process. Because of this dryer is designed using artificial
heating system with forced convection. Dryers is designed for the capacity of 2 kg per hour. It has
components : dryer room, plats, space heating, hot conduit, a chanel for the fan and the evaporation
air stream through all the components. LPG is used as fuel and heating burner is completed with
an on off system controler. To dry 2 kg of fish pellet with 30% to 15% water content required 5
pieces of plats 30 cm x 30 cm dry air flowrate 17 m3/menit. After drying, the water can be
evaporated from pellet was 0,3 kg. In one-time process dryer can produce 1,7 kg pellet. From the
test conducted, the time required to dry 2 kg of fish pellet only takes 32 minutes. With room
temperature is set 60-80 oC.
