DEVELOPMENT OF ECONOMIC INFRARED OVEN
Main Article Content
Abstract
Infrared oven was developed by using a card-board box as an oven and an infrared lamb for drying samples. The box wrapped with aluminum foil generated higher temperature at the center of radiated area than the uncovered one after infrared radiation was applied. Maximum temperature in the former reached 160 to 170 oC. In aluminum foil-covered treatment, temperature decreased from 120-130 to 106-107 oC at the distance of 1.5 and 4 centimeter from the center of radiation incidence respectively. Optimum distance between feed sample and infrared lamp was 12.0-12.5 cm. The results indicated that the best incubation period was 20 minutes which similar to the optinum period obtained from a conventional method using electrical incubator.
