<br/><br/> Common charcoal briquettes are made of coconut husk, they undergo certain processes<br/>using different machines to achieve the desired quality of briquettes considering the<br/>compactness, density, and its burning capacity. One of the machines that provides the<br/>molding process and determines the compactness of the charcoal is the briquetting<br/>machine. For common machines like this, they are using screw-shafts driven by the motor<br/>to press and push the charcoal powder mixture through the die/molder, it has a mechanical<br/>taper that gradually pushes through the mixture to perform compression and afterwards it<br/>formed a briquet. The main objective of this study is to develop a briquetting machine that<br/>could increase the rate of output compared to other machines. It has a dual extruder and<br/>two molders to increase the rate of output at a certain time, based on the results from<br/>50kg/hr. that produces 308 pieces of briquettes, the prototype can reach 134kg/hr. that<br/>produces 960 pieces of briquettes, this was achieved by adding additional compression<br/>section to the machine. An automatic cutting has been added as a feature of the machine,<br/>the purpose of this is to lessen the human intervention in terms of cutting the outcoming<br/>briquette from the molder and provide equal size and cuts to the charcoal. Test results<br/>showed that the machine could mold a briquette with an average of 80 pieces in span of 5<br/>minutes with an average weight of 11.2 kilograms. For the performance of the machine, it<br/>is presented to 30 evaluators and obtained the grand mean score of 4.82 equivalent to a<br/>descriptive grade of Excellent. This concludes that the developed prototype met the desired<br/>results and objectives set by this study.<br/>Keywords: briquette, extruder, screw-shaft, automatic cutting, briquetting machine
