5. Ease of Maintenance: Designing machines for easy cleaning, maintenance, and parts replacement.

Components of Rice Mill Machines

A rice mill typically consists of several interconnected machines, each with specific components:

1. Paddy Rubber Roll Husker:
   • Rubber Rolls: Two rubber rolls that rotate in opposite directions to dehusk the paddy.
   • Husking Chamber: The space where husking occurs, designed to optimize contact between the paddy and rubber rolls.
   • Husk Separator: A system that separates husks from the brown rice after husking.
   • Feeding Mechanism: Controls the flow of paddy into the husker for consistent processing.
2. Emery Polisher:
   • Emery Roller: A cylindrical roller coated with emery, used to polish the rice grains.
   • Polishing Chamber: The area where polishing takes place, ensuring even contact between the rice and the emery roller.

   • Discharge Outlets: Separate outlets for different grades of rice.
   • Feeding System: Controls the flow of rice into the grader to ensure consistent separation.

Working Principle of Rice Mill Machines

• Paddy Rubber Roll Husker

The paddy rubber roll husker operates based on the principle of differential speed and pressure. Paddy is fed into the husking chamber, where two rubber rolls rotating at different speeds create friction and shear forces that strip the husk from the rice grains. The husks are then separated from the brown rice using a husk separator, and the dehusked rice moves on to the next stage.

• Emery Polisher

The emery polisher works by abrasion. The brown rice enters the polishing chamber, where it comes into contact with the emery roller. As the roller rotates, it rubs against the rice grains, removing the bran layer and polishing the surface. Air blowers assist in removing the bran and dust generated during polishing, ensuring a clean and smooth finish.

• Grader Machine

The grader machine functions on the principle of size separation. Rice grains are fed into the grader, where they pass through a series of vibrating sieves with progressively smaller mesh sizes. Larger grains remain on the top sieve, while smaller grains fall through to the lower sieves. The process continues until the rice is sorted into different grades based on size and quality, which are then discharged through separate outlets.
