Development of a dually operated biomass briquette press

Abstract

Technological transformation of biomass residues into briquettes is essential for industrial energy applications. This research was undertaken to design, fabricate, and test a dually operated screw press for briquette production. The machine was designed and fabricated using 0.3%-carbon steel, and its performance was evaluated for 30 min at an interval of 5 min. The efficiency increased with an increase in the resident time, and the values were approximately 95% and 80% at the end of the 30 min motorized and manual operations, respectively. The average capacity of the manual operation was 0.0025 kg s-1 and that of the motorized operation was 0.0055 kg s-1 . A single phase two horsepower electric motor was used to power the machine.
