Polisher: how it works

  1. White rice from the whitener enters a chamber around a turning shaft.
  2. A very fine mist of water is sprayed in, which softens the bran dust still stuck to the grains.
  3. The grains rub gently against each other and against the screen, which wipes the surface clean and smooth.
  4. Air draws off the loosened bran and dries the surface before the rice leaves.

Main types

Water mist polisher
Polishes with a water mist; often called a silky polisher. The standard in modern mills.
Dry polisher
Brushes or leather strips rub the rice without water. An older, simpler design.
Single-pass and double-pass
One or two polishing chambers in a row; two passes give more shine.

Where it fits in the process

It follows the whiteners. Polished rice goes on to the length grader and the colour sorter.

Common questions

What does a rice polisher do?

It removes the fine bran dust left on white rice and smooths the surface of each grain. The rice looks cleaner and glossier and keeps longer, because the oily bran that turns rancid is gone.

Does polishing wet the rice?

No. The mist is very fine and the amount is small; the air in the machine carries it off with the bran, so the rice leaves dry. Too much water, though, makes the rice sticky and is a setting to watch.

What is the price of a rice polisher machine in Bangladesh?

We do not publish prices. The price depends on the type, single or double pass, how much rice it must polish in an hour and whether the machine is new or reconditioned. Send us the points listed above and we will quote.
