An organic fertilizer mixer was designed and evaluated at Cavite State University —
Main Campus, Indang, Cavite. The principal components of the machine are the cover, inlet,
mixing chamber, mixing paddles, steering handle, outlet, main frame, and wheels.
The machine was designed according to the availability of local materials, ease of
operation and maintenance, and one-man operation. The machine also contributes to energy
saving because it was manually operated. The performance of the machine was only limited to
the evaluation of its capacity and mixing uniformity.
The test materials used were 4.8 kg cattle manure, 4.8 kg chicken manure and 0.4 kg of
sawdust. The machine was evaluated with three number of revolutions per minute: 60, 120 and
180 rpm. The average uniformity of mixing solid mixture with and without IMO is 82.72% and
80.96%, respectively. The capacity of the machine is 284.56kg/hr and 398.5 Ikg/hr for mixtures
with and without IMO, respectively.
The total machine cost was PhP20,436.5. The solid mixture without IMO has a payback
period of 1.15 years, breakeven point of 7,572.43 kg/year and benefit cost ratio of 2.73. For
mixture with IMO, the payback period was 0.44 years, breakeven point of
9,250.83kg/year and benefit cost ratio of 1.94.
