Controlling Temperature of Corn Cob Briquette Materials Using Automatic Induction Heater

Abstract

Corn Briquettes can be made using direct combustion such as burning of fuel. But this methode is unhealthy which can produce danger particles and smoke.  One methode to burn something without direct burning is using vessel reactor (oven). This research aims to built an electric oven using induction heater. Controlling oven temperature was conducted using induction heater automaticly. The temperature of the oven will be controlled automaticly by varied the induction heater. Oven was built of 3 (three) item induction heater and was set in 3 (three) condition. At first condition, first heater is set at 50^oC. After reaches 50^oC, the second induction heater is on, then at 100^oC the third induction heater is on. Maximal value of temperature is 300^oC. With Corn Briquette Materials is in the oven, it wil be created briquette charcoal. A microcontroller based thermocople K-Type sensor will control these condition. It achieves 50^oC, 100^oC and 300^oC each for 1^st heater, 2^nd and 3^{rd .}  For 20 minutes oven temperature reaches 50^oC, after next 100^oC in 1 hours and reaches 300^oC in 4 hours, the material reduces it’s weight about 20 grams in 4 hours starting in 50^oC.
