Design and development of a multi-tasks motorized ginger rhizomes juice expression machine

Manual ginger juice expression processes are tedious, unhygienic, and inefficient, affecting the quality and quantity of ginger juice extracted. Extraction by chemical means is complex, expensive, and requires high skill to operate. The developed motorized ginger juice expression machine performs two distinct unit operations: size reduction and separation processes. Major components of the machine include the feeding unit, pulverizing unit, juice expression unit, juice drainage point, waste outlet, frame, and power transmission system. The machine is powered by 2 H.P., 1400 rpm and 1 H.P., 1430 rpm prime movers, and the V-belts and pulley assembly speed are 646 rpm and 240 rpm, respectively. The developed expression machine offers an affordable and simple method of processing fresh ginger minimizing loss in ginger rhizome quantity and quality, and ultimately reducing postharvest losses.
