Design and Development of a Domestic Biscuit Cabinet Tray Dryer

A locally made biscuit cabinet dryer to be operated in homes was designed and developed to prepare biscuits in Nigeria homes. A thorough study of the imported dryer for home use was done. Design drawings and calculations were established and the machine was fabricated with well selected materials and components all sourced locally. The 714mm x 574mm x 984mm box shaped cabinet was constructed using mild steel and fiber glass was used as insulator to control heat loss by conduction The performance of the fabricated cabinet tray dryer was finally evaluated against an imported cabinet tray dryer in using a t-test analysis at 95% confidence level, and the result showed that there is no significant difference between the locally fabricated and the imported dryers.
