An experiment to study the influence of shelling methods on corn quality and store-ability was conducted at Karawang Sub Station in 1983. Five moisture content (21-22 percent, 19-20 percent, 17-18 percent, 15-16 percent and 13-14 percent) and two shelling method treatments (hand sheller and grater/"parut") were used. The shelled corn was sundried to 12 percent moisture content and stored in plastic bags for 3 months at ambient temperature. At the end of drying process, the capacity of grater (parut) was 5,5 kg shelled corn/man/hour and 2,5 kg for hand sheller. The shelled corn quality of all moisture content treatments were 0.27-0.70 percent broken and 7.43-13.47 percent damage for grater respectively. The shelled corn quality at all moisture content treatments of hand sheller and highest moisture content of grater were completed on quality standard requirement with maximum 5.0 percent broken and 9.96 percent damage. At the end of 3 months storage, the grain damage were 35.0-0-40.76 percent for hand sheller and 60.60-68.69 percent for grater at all moisture content treatments. The lower damage were produced by lower moisture content treatments on both sheller.
