The processing of cassava mash (garri) over the years has been a lucrative business for farmers in Nigeria. Unfortunately, this business has been run in small scale due to the unavailability of the mechanized and industrial machine that will facilitate the production in large scale necessary for export purposes. This paper, is meant to bring to light The automatic controlled garri frying machine incorporated with microcontroller so as to improve on mechanization of the production of gari in Nigeria. The frying machine operates with an electrical heating element of 5kW and a gear motor of variable speed. This makes it an improvement on other machine which operates on charcoal or gas burner for heat sources to fry the cassava mash. And also a programmable controller is used for controlling the operation of the heating element and the gear motor, making it a semi-automatic machine. It has a display interface on the machine control panel that displays the instantaneous temperature of the garri. The machine operates with a peak temperature of 900C and it has a vibrator which maintain smooth frying operation, thereby avoiding bunning and caking or clustering of garri grains due to uncontrolled and unstable high temperature. The height of the machine is 920mm with a diameter of 700mm. The material used for the internal frying pan is stainless steel of 1.5mm thickness welded with a thungsten electrode to ensure that the garri is safe from any food poisoning as a result of corrosion. The body is constructed with mild steel of 4mm thickness. The top support frame is constructed with mild steel of 8mm thickness. The machine is supported with a pair of tyre to facilitate movement .After the construction, the machine was tested and it was found that the machine function optimally. The project can be mimicked by both the students of the department of mechanical and electrical engineering of to enhance their knowledge on mechatronics. Furthermore, it can be constructed in larger capacity to process more tons/hour for industrial purposes.
