Materials Selection And Fabrication Practices For Food Processing Equipment Manufacturers In Uganda

摘要

The food processing industry is one of the fast-growing sub-sectors in Uganda. The industry, which is majorly composed of medium and small scale firms, depends on the locally developed food processing equipment. Due to lack of effective materials selection practices employed by the equipment manufacturers, the materials normally selected for most designs are not the most appropriate ones hence compromising the quality of the equipment produced. This has not only led to poor quality food products due to contamination but could also turn out health hazardous to the consumers of the food products. This study involved the assessment of the current materials selection and fabrication procedures used by the food processing equipment manufacturers with a view of devising best practices that can be used to improve the quality of the food products processed by the locally fabricated equipment. Results of the study show that, designers' experience biasness and desire to minimize cost compromise the materials selection procedure. In addition to failing to choose the best material for a given application, most equipment manufacturers are commonly fabricating equipment with inadequate surface finish and improper weldments. This hinders the equipment's ability to meet food hygiene standards.
