Impurity Separating Machine for Paddy Rice

Abstract

The paddy seeds stored by farmers in cultivation need to be sorted through impurities such as husks, rocks, soil, sand and dust. The aim of this paper is to create an impurity separating machine to facilitate the separation of such impurities from the seeds of cultivated rice.This machine can sort impurities out of rice seeds. It have a 2-sieve, 3-layer system was used for separate. The first layer was a long oval sieve used for separate impurities larger than paddy, the second layer was a small circle hole sieve that receive the paddy, and the third layer is a tray to collect impurities that are smaller than paddy rice. It will fall from the second sieve. Induction motor are used instead of an engine and human power. Rice seeds that have not yet been sorted after harvest from the fields are sorted to keep the rice clean with this machine. Mix the impurities obtained from the sorting back into the grain with a ratio of 9:1 and then sort them with an impurity sorting machine. It was found that the result of impurities separation was 83.8 percent on average. This machine can reduce time, reduce labor and save cost than using the engine, including having a belt cover and circuit breaker to make it safe while the machine is working. It can also measure electrical parameters such as voltage, current, power factor and calculate electric energy values. By test install to find the size of the motor that is right for use. Get the right motor and make clean rice varieties for farmers to cultivate.
