Murukku is a delicious south Indian snack product prepared at household level as evening snack and also during festival seasons. The developed semi-automatic murukku extruder comprised of electric motor, power transmission system, a self-reversing screw rod, dough barrel and piston, die, and collection tray. The performance evaluation of extruder was done under three different moisture content of dough viz., 24%; 25%; and 26% respectively, and also at three different speed of self-reversing screw rod viz.,18 rpm; 15 rpm; and 12 rpm respectively. The statistical evaluation of extruder efficiency and sensory evaluation of final product samples was done. The results indicated that the efficiency of murukku extruder was found maximum when the dough moisture is at 25% and the speed of self-reversing screw rod at 12 revolutions per minute.
