1. Pre cleaning
Although paddy grain may have gone through a cleaner before drying. Cleaning paddy prior to husking and whitening is crucial in attaining high milling recoveries.
2. Destoner
The de-stoner is an important component of the rice mill, The grain gathers a lot of stones and mudball during handling, which must be removed. The de-stoner is a simple vibrating deck and air blower that suspends the grain from the stones. The stones are thrown off in one end and the paddy in the other end.

3. Husking / de-hulling

Husking or de-hulling is a process for removing the rice hull from the rough rice. We use rubber roller husker.

4. Paddy Separator

In order to separate the remaining unhusked paddy grains from from the brown rice fraction and feed them back into the husker a paddy separator is used.

5. Polishing

White rice is produced from brown rice by removing the bran layer and the germ. The bran layer is removed from the kernel by applying friction to the grain surface rubbing the grains against an abrasive surface. The amount of bran removed is normally between 8-10% of the total paddy weight but this will vary according to the variety and degree of whiteness required.

6. Mist Polisher

Mist polisher is employed to brush off remaining bran dust and to create a characteristic gloss on the milled rice. In mist polishers, a controlled amount of water mist is injected, resulting in highly polished grain. Mist polishing improves the storability of milled rice because of the complete removal of the bran.

7. Length Grader

The major step in the modern milling process is the removal of the brokens from the milled rice, Length grading separates “head rice” from large brokens. Blending stations allow for mixing of head rice and brokens in the correct proportion, as specified by the grade standards. For instance, premium grade rice in the India allows for 95% head rice and 5% brokens.

8. Italian Color Sorter
Automated separation of grains based on color and surface texture.

9. Bagging Station

Milled rice is marketed in bags, and therefore bagging stations from an integral part of the modern rice mill. The sizes of the bags depend on the requirements of the customer. In our mills, milled rice is packaged in plastic / Non Woven bags of 25, 35 and 50kg, and packaging is fully mechanized.
