Cheese was prepared in a small scale at the Department of Agricultural technology Laboratory Kwara State Polytechnic Ilorin, Kwara State, and analysis of some parameter was carried out on evaluation of cheese quality using graded levels of different plant extracts as coagulants such as C.procera, C.papaya, and lime fruit juice. The Parameters analyzed for were, Weight of the cheese, Colour of the cheese, pH of the whey, Time of coagulation, Texture of the cheese Taste of the cheese and Palatability of the cheese. At the end of the experiment, it was concluded that lime fruit juice can best be used as a coagulant in the production of cheese. The use of lime as milk coagulant gives the best cheese out of the three coagulants used. Although other two coagulants did almost equally well. | Abstract
Irrigation, which is the artificial application of water to the soil for the purpose of crop production, has been one of the major ways to increase the productivity of agriculture. Drip Irrigation which is one of the varieties of Irrigation has not yet been popularized because of its sophistication and high cost. As such, this project sets out to construct a simple and affordable drip irrigation system which comprises the PVC pipes, micro-tubings which are used to construct the flow paths and emitters or drippers. It was observed that the discharge per emitter for a particular position did not fluctuate much, rather there was a sharp increase in emitter discharge as the emitter regulator was adjusted upwards. This work recommends, among other things, that government(s) should encourage further research works in Irrigation, in order to develop simple and affordable Irrigation systems, both low and high-pressure ones. | Abstract
The solar drying system utilizes solar energy to heat up air and to dry any food substance loaded, which is not only beneficial in that it reduces wastage of agricultural produce and helps in the preservation of agricultural produce. Based on the limitations of the natural sun drying such as exposure to direct sunlight, liability to pests and rodents lack of proper monitoring, and the escalated cost of the mechanical dryers, a solar dryer was therefore developed to cater for this limitations. This project presents the design and construction of a domestic passive solar dryer, the dryer is composed of solar collector (air heater) and a solar drying chamber containing rack of three trays both being integrated together. The air allowed in through air inlet is heated up in the solar collector and channeled through the drying chamber where it is utilized in drying (removing the moisture content from the food substance or agricultural produce loaded). The design was based on the geographical location which is Abeokuta and meteorological data were obtained for proper design specification. The dimensions of the dryer was 94cm x 45cm x 101cm/ 20cm (length x width x height). Locally available materials were used for the construction, chiefly comprising of wood (gmelina), polyurethane glass, mild steel metal sheet and net cloth for the trays. |
