Food processing industry, specifically flour production from cereals like maize, sorghum, millet,
and wheat, became more important for value additions in presently according to the cooking
restrictions and the quality needed for good products, particularly at SOSOMA industries LTD in
Rwanda. To get a quality product, various processing stages including cereals roasting, milling,
sieving, fortification and vitamins premixes, and packaging must be monitored and controlled on
real time. During roasting, the status of an industrial oven affects the quality of the product, and
needs to be considered and followed up on a real time basis. It uses wood fuel as a source of energy,
and when not controlled, can produce smoke flames and carbon monoxide in the working
environment that may affect the respiratory system of employees who are closer in proximity and
the working environment itself. When controlled well, it adds nutrients in the roasted cereals. In
this study, a qualitative approach of data collection like unstructured interviews, discussion and
field visit observation was used and data have been analyzed using content analysis techniques just
to obtain system requirements. Various electronic components such as sensors to capture the
physical environment, microcontroller to define tasks, SPI protocol to enable communication
between devices, and output devices to react to environmental change have been used to design and
develop a fully monitored and controlled industrial oven. Ultimately, the developed system was
tested positively and found to meet the industry oven requirements, so it was accepted at
SOSOMA industries due to its effective low cost, secured and friendly system.
