What are the 3 ways rice can be processed?

The main rice processing steps can be divided into paddy cleaning, paddy husking, and rice milling.

What are the parts of a rice milling machine?

The spare parts of a rice milling machine include the rice huller screen, the huller blade, and the whitening cylinder. Because of the frequent friction that occurs between these parts and the grain, many spare parts are easily worn down to some degree.

What simple machine loosens the husk of the grains?

Mixing varieties will generally lead to lower quality of milled rice. Rubber roll huskers produce the best quality. Engleberg-type or “steel” hullers are no longer acceptable in the commercial rice milling sector, as they lead to low milling recovery and high grain breakage. Separate all paddy from the brown rice before whitening.

How to improve the quality of the rice?

To improve the quality of the rice, factors such as the paddy quality and milling technology should be considered. To obtain good paddy quality: A moisture content of 14% MC is ideal for milling. If the MC is too low, high grain breakage will occur resulting in low head rice recovery.
