Destoner

If you ever visited a rice mill you would have seen a set of machinery for different tasks. Have you ever wondered how impurities such as small stones, traces of mud, soil particles are separated rice or wheat? For removing soil particles from the wheat stock the conventional methods is to wash it thoroughly and left to dry in the sun. However, this method only removes the soil particles and not the stones. Nevertheless this technique cannot be applied to rice. So, to deal with the problems of impurities, such as soil particles, small stones, and mud a Destoner is used. It is a machine that uses grain specific gravity to separate these impurities from wheat, rice, coffee beans, and paddy.

A Destoner comes in different sizes and design depending on the application requirements. It contains a vibrator motor that vibrates rice or wheat fed into the machine. Through this vibration the lighter material gets separated and filtered through a large sieve attached to the machine.

Manufacturers design several types of Destoner including connecting type destoner machine and vibratory destoner. These machines are equipped with webs for removing the soil particles and stones. When the machine starts, the stone gets attached to the web while the soil particles fall through the web. The stones move further to be collected in a boulder box. The smaller stones are taken to a trench with the help of a cross conveyor while the bigger stones are collected in a boulder box.

Structure of Destoner

A Destoner consists of mainly feed hopper, aspirating hood, a machine stand, a sieve box, an eccentric driving mechanism and some other components. In the machine a special rubber bearing is used for the hinge joints of the machines reciprocating oscillation mechanism. The rubber bearing can absorb strong vibration and ultimately protects components and parts from abrasion or friction with each other. Rice or other grains are fed though the feeder hopper which moves to the sieve box. When the machine starts it moves the sieve in reciprocating oscillation which leads to separation of impurities from the grain. These machines use different size of the mesh of the sieve to sift the impurities and collect in the sieve box. While operating the machine the slope angle could be between 10o to 14o to regulate the flow of the grain.
