The design of disc patterns for pepper mill

Abstract

The purpose of this research is to improve the pepper mill for increasing performance. The characteristic of the pepper mill is a trapezoid shape. The structure is made of angle steel and stainless steel sheet. The motor used a power unit is 1 hp, and send the power to the driving belt for driving the disc. There are new pattern of designed discs. The discs are made from stainless steels and have three different patterns on the surface of discs. Each test must measures the moisture contented of the pepper seeds. If the moisture is less than 9% can be milled. However, if the moisture is more than 9% that must be taken pepper seeds to sunning or drying. The test is 10 sets in each set of test using two samples of pepper seeds. In each test, pepper seeds must be weighted before the milling when they are milled the finish. After that, they are brought the milled pepper seeds to a weight and separated a size. The sorting by size is 5 sizes as a less than 5 microns, 150-250 microns, 250-425 microns, 150 microns, 425 to 1,000, and more than 1.00 mm. The results of research shown that pattern of discs will give the different pepper powder sizes
