Design and Fabrication of a Mono-Bloc Mixer Extruder Machine for The Production of Gum From Cassava Starch
The machines for gum production from cassava starch are very expensive and complex which made it difficult for local cassava farmers to procure, install and operate. A simple machine known as Mono-bloc mixer extruder machine for the production of gum from cassava starch was designed and fabricated using locally available materials. Several experimental procedures were carried out which include the selection of materials for the machine, design calculations for the various parts of the machine, performance evaluation test and efficiency determination. Performance evaluation test and observation revealed that for best results, the cooking time of the starch solution with other gum additives should be 30minutes and the cooking temperature had to be in the range 800C – 950C (within the dextrinization zone). The results also revealed that the designed and fabricated machine could produce gum from cassava starch effectively and easy to install, operate and maintain. The machine produced had a capacity of producing 5.175litres of dextrin gum per minute and an efficiency of 85%.
