Abstract
For the automation of Koji incubation process, microcomputer based Koji incubation system was built and applied to acquisition of the process variables, and to control of the Koji incubation process. The incubation variables included the relative humidity and Koji weight. And data measured were sent to the microcomputer by the interface device built with MC 6821 PIA. Incubation environment conditions -temperature and humidity- were controlled by the actuation of heater and mist sprayer with on/off signal generated by ASIC program. Aspergillus oryzae as a starter of the Koji and steamed barley as media were used and Koji was successfully manufactured both at
