The Development of the rice sorting machine

Abstract

Thailand is an agricultural country. Most of the population consists of farmer. The rice is suitable to the climate of the country. And the main export of Thai is rice. The preparation of grain is also important.The farmer have to has an experience to choose the grain for growing the rice in farm. Good grian will give the high product. And good grain should completely free from contamination of disease and insect. Then it will be healthy seedlings. It is easy to harvest crops in a very high quality. Even it has good and high quality but it still has in impurities in the seed. Then the idea to create a project of sorting impurities from seeds. From the first it was built to help farmers to separate impurities such as grasses and husks. But the problem is the size of the maching is 140 x 150 x 160 cm which is larg and heavy, then it makes the inconvenient to move. The preparation of the project is to develop an interest in sorting impurities in grain. The objective is to reduce the size to a smaller size than before. And increase the work more efficiency. The main aim is to sorting impurities in grain. Preparing the rice and put into the machin, when power is opened. Rice will be flowing through the sieve, which it works as a distribution and contamination. Then it will fail down into the sorting room. Impurities will be removed, and the wind from the fan will blow the seeds. So we will get the good product and high quality. The results of the test. Wind is the best performance of the machine. Separating rice grains is 5.4 meters per second. The test of separating of the rice grains in 5 times and in the test of the 10, 20, 30, 40 and 50 kg, with a mixture of 10 percent of husk. the most effective of sorting rice is 10 kg. It can be isolated 99.30 percent with in 1.23 minutes.
