Design and Construction of an Electric and Automatic Incubator for the Incubation of Chicken Eggs at the Higher Institute of Technology of Mamou, Guinea

The objective of this study is to design and build an electric and automatic incubator for the incubation of chicken eggs. The methodology consists of: determining the geometric parameters of the incubator; choose the various electronic and electrical components; build the incubator; program the various commands, make the heat balance; draw the diagram of the whole system and experiment with the incubator. The incubator produced is characterized by the dimensions (80×66×32.5), with three (3) racks with an area of 3600 cm2 each and the number of cells per rack is six. The total daily thermal balance relating to the device is 2551.744 kJ. The average daily vacuum test temperature and humidity indoors and in the ambient are 37.24°C and 57.68% respectively. During the 21 days of incubation, the average internal temperature varied from 36.10°C (21st day) to 37.65°C (3rd day), with an average of 37.20°C. The relative humidity varied from 53% (7th day) to 74% (20th day), with an average of 59.61%. The device produced made it possible to hatch 470 eggs out of 540 in the incubator, i.e. a hatching rate of 87%. Keywords: Incubator, Chicken eggs, Design, Electric, Automatic.
