DESIGN AND DEVELOPMENT OF COCONUT DE-SHELLING MACHINE.

摘要

Traditionally after drying of split coconut, the kernel and copra is weparated using traditional wooden mallet by taking the individual cups in hand. To over come this problem, a power operated coconut de-shelling machine was designed and developed. The capacity of the machine was 400 half cups per batch. The optimum average moisture content for maximum de-shelling efficiency(92.16%) was 35%d.b. The optimum speed of the de-shelling machine was 10 RPM and the time taken for de-shelling was 4 minutes per batch. Cost of the machine was Rs.27,100 and the cost of de-shelling 1000 nuts was Rs.53.00.
