ABSTRACT
This thesis is on the design of the building services requirement of a dairy plant. Investigation of the engineering services problems of four existing medium scale dairy plants at Kaduna, Funtua, Jos and Minna showed that the greatest problem of the dairy industry is sanitation, and the building services requirement being: Water (cold and hot) services, sewage disposal, Refrigeration and Airconditioning. The work therefore tried to optimize the design of these services based on production capacity of 18,000 litres of milk products per shift of 8 hours. Factors considered in the design included the number of people that work in the plant, the processes that the milk products undergo in the industry which determine temperatures of the various rooms, the hot and cold water demand the nature of wastes and waste treatment, and the refrigeration capacity. The work investigated pipeline and insulation problems and specified materials and sizes. The production capacity and processes determined the machine and equipment specifications. This in turn determined the plant layout and manpower requirement as shown in the organisation chart. The building services were then designed to suite the plant layout. Detailed designs of the plant layout and these building services are shown in Drawings 1 to 6 vi (folded and attached at the back cover). The various component designs are illustrated in figures 1 - 43 The design of the storm drainage system is based on the severest rainfall intensity in Kaduna as shown in tables 4-13 extracted from the Agro-Meteorological Bulletin of Nigeria (1980-1983).
