Abstract

A screw conveyor type of pig feed mixing machine was designed, fabricated, and evaluated. The machine comprises the following major components; hopper, frame, mixing chamber, Mixing bar, screw conveyor chamber, screw conveyor, shaft, Electric motor, and pulleys. The uniqueness of this screw conveyor type of pig feed mixing machine lies in the uniqueness of its design where the mixing process and the dispensing process of mixed feed were carried out in one run of operation. Some design parameters such as the capacity of the hopper, the volume of the mixing chamber, shaft diameter, the power required were calculated for. The result derived from the calculated design parameters were used for the fabrication. The performance evaluation of the machines was determined in terms of the throughput of the machine, the machine efficiency, and its ability to mix various components of the feed. The machine was tested using feed ingredients that carefully divided into four equal weight of 15 Kg of fine rice bran, 5 Kg of corn brand, 2.5 Kg of the palate, and 2.5 Kg of coarse ground corn replicated thrice at four mixing durations of 5, 10, 15 and 20 min. The performance test shown that the average mixing time of feed ingredients in the mixing chamber was 12,5 min, the average time for a batch production process was 18.750 min, the average production rate was 1.4 Kg/min, and the average machine’s efficiency was 97% indicated that the mixing machine can be of tremendous usage to feed mixing. In terms of the machine ability to mix various components of feed the test revealed that the average degree of mixing in respect of the four mixing durations considered at 90,708 % attained at the average of 12.5 minutes of mixing time. The higher mixing performance for the mixing machine’s was 15 minutes plus 6 minutes of conveyed time. It was revealed that the degree of mixture approach to its equilibrium level at 15 minutes of mixing time with 97.460 % degree of mixing. Therefore, further mixing time will not produce a better degree of mixing.
