The performance evaluation of multipurpose mixer was carried out using various volumes of water plus juice and water plus sugar. Various volumes of samples containing water plus juice and water plus sugar were first prepared and it was ensured that the same quantities of each of the samples were mixed by the multipurpose mixer and the conventional mixer. The results obtained for multipurpose mixer were compared with the performance of the conventional mixer under the same conditions. There exist a constant mixing time ratio (1:6) for the multipurpose mixer and conventional local manual mixer at 60, 120, 180 and 240 liters of mixers, but at 300 liters the mixing time ratio was increased to 1:7 and at 350 liters and above; the efficiency of multi-purpose mixer was found to be 75%. When compared with conventional mixer. The performance evaluation reveals that at higher content of liquid, the performance of the conventional mixer reduces, whilst there is an improved performance in the case of multi-purpose equipment. The reason for this cannot be far fetch from the fact that while the multipurpose mixer is power driven the conventional mixer is manually operated by an operator. The result obtained reveals what is obtainable at pilot scale analysis of the mixers. The study shows that mixers that are operated manually may not be advisable for medium scale industries and above where mixing of liquids or slurries are involved because conventional mixer are likely to take longer time of operation when it comes to large scale production and enhance increases production time and cost.
