Abstract
The study of temperature uniformity on multi-shelf drying equipment, using fuel as the drying energy was done. This study uses a 10-level dryer. The system of heat divider to the drying chamber is equipped with a sharp turn channel to equalize the temperature in the drying chamber. The hot gas distribution system is conducted by natural convection. This drying equipment system is also equipped with a combustion chamber, heat level, hot gas divider channel, drying chamber, and chimney. The type of fuel can be selected from LPG, fuel oil, and other solid fuels. In this test, the temperature in the drying chamber can be used between 60 and 90 °C. With a 60–90 °C, the temperature in the combustion chamber is 400–500 °C, the temperature in the hot gas channel is from 120 to 90 °C and the exhaust chamber temperature is 50–75 °C. From the test results, it was found that the temperature in the drying chamber between the first shelf to the highest shelf was 1 °C vertically, and the temperature difference was 0.2–0.5 °C horizontally. It can be said that the temperature distribution in the drying chamber is uniform. After being tested, the drying capacity for fish is 50–80 kg, drying time is 10–12 h with the water content of dried fish reach 12–15%. For drying fish 50 kg, requires 4 kg of LPG.
