Abstract

The current working process of corn kernels is removed by crushing manually by hand so it is very tiring and low productivity. To speed up the shelling process, it is necessary to design a model of the corn sheller which is expected to be able to remove the corn kernels from the cob. The method used in this rotary method of removing corn kernels uses a prime mover in the form of an electric motor which is connected to the drive shaft through pulleys and belts that will process the release of corn kernels. Thus, this study is aimed to investigate the ability of shelling process to reduce the workload and increase work productivity. Corn sheller machine with rotary method with dimensions of 950 mm high, 755 mm wide and 750 mm long using a 0.25 HP electric motor as the main driver. This machine has 2 functions, namely as a corn kernel thresher and corn kernel size separator. In the corn kernel threshing section there is a sheller knife with a diameter of 76.2 mm and a length of 600 mm. The corn kernel separator is slightly conical in shape with a diameter of 250 mm on one side and 200 mm on the other. This is so that the corn can move from the side that is 200 mm in diameter to the side that is 250 mm in diameter. The corn kernel sheller and separator uses a 1” diameter shaft. This tool is also equipped with a blower that functions to clean corn kernels from the corn cob skin that comes off during shelling. Based on test results, the time for shelling corn seeds using this corn sheller machine takes an average of 8.30 minutes for 50 kg of corn cobs. While the time required for the manual shelling process for 50 kg of corn cobs is an average of 56.73 minutes. Work productivity by using shelling machine increased by 588% from 0.0084 manual shelling process and work productivity increased to 0.051 using corn sheller machine.
