rice polisher principle is to use electricity on continuous moving parts and uses a manual system the regulator components. Components are driven by electricity like rubber rolls and air blower. Components are driven by manually like shutter, feed adjuster, roll gap adjuster and wind adjuster.
Water is used for soaking and steam generation. Electricity is the main energy source for these rice mills and is imported form the state electricity board grids. Electricity is used to run motors, pumps, blowers, conveyors, fans, lights, etc. The variations in the consumption rate of energy through the use of utilities during processing must also accounted for final cost of the finished product.
The paddy milling consumes significant quantity of fuels and electricity. The major energy consuming equipments in the rice milling units are; boilers and steam distribution, blowers, pumps, conveyers, elevators, motors, transmission systems, weighing, etc.
The hulling-principle of the third huller is based on centrifugal-force and is therefore called the Centrifugal-huller. The rice destoner consists essentially of the accelerating disc, the drive unit and the huller-drum. To achieve optimum hulling-efficiency, the disc must rotate at a speed in the range of 3000 to 4000 rpm. By opening the feeder-gate, paddy is fed into the center of the rotating disc. The impact caused by the rotating catchers of the disc is sufficient to crack the husks when they crush against the huller-drum. To avoid brockens, the drum is made conical and covered with a rubber cushion in the hulling area The high kinetic energy and air flow causes the husks, together with the brown rice, to be expelled at the bottom of the drum. Compared with the Engelberg-hullers, this machine requires much less power at a high-level capacity and also reduces brockens.
