Broken rice is a common problem when using a rice milling machine<\/strong>. A high broken rice rate can reduce whole-rice yield, finished-rice quality, and overall profitability. The causes may include paddy moisture, machine settings, raw material quality, and equipment condition.<\/p>

Incorrect Paddy Moisture<\/h2>

Paddy that is too dry becomes brittle and is more likely to break in a rice miller<\/strong>, while excessive moisture can affect husking and whitening efficiency.<\/p>

Solution:<\/strong> Control paddy moisture before milling and adjust it according to the rice variety and processing requirements.<\/p>

Excessive Milling Pressure<\/h2>

A rice husking machine<\/strong> uses friction and pressure to remove the bran layer. Excessive pressure can create too much mechanical stress and increase rice breakage.<\/p>

Solution:<\/strong> Adjust the milling pressure according to the rice variety, grain condition, and required whiteness. Avoid using unnecessarily high pressure.<\/p>

Improper Rice Miller Settings<\/h2>

Feed rate, roller speed, airflow, and milling pressure all affect the performance of a rice mill machine<\/strong>. Incorrect settings may cause uneven processing and excessive broken rice.<\/p>

Solution:<\/strong> Follow the recommended operating parameters and make gradual adjustments according to actual milling results.<\/p>

Poor-Quality Paddy<\/h2>

Cracked, immature, or poorly dried paddy is more vulnerable to breakage during processing. Even a high-quality rice mill<\/strong> cannot completely eliminate problems caused by poor raw materials.<\/p>

Solution:<\/strong> Use well-dried, high-quality paddy and remove impurities and unsuitable grains through proper cleaning and grading.<\/p>

Excessive Feeding Rate<\/h2>

Overfeeding a rice milling machine<\/strong> can overload the milling chamber, increase friction, and reduce processing stability.<\/p>

Solution:<\/strong> Keep the feeding rate within the machine’s rated capacity. For a complete rice milling plant, make sure the capacity of cleaning, husking, whitening, grading, and conveying equipment is properly matched.<\/p>

Worn Rice Milling Machine Components<\/h2>

Rollers, screens, rubber parts, and other components of a rice milling machine<\/strong> can wear after long-term operation. Worn parts may cause unstable pressure and uneven grain processing.<\/p>

Solution:<\/strong> Inspect the machine regularly and replace worn components in time to maintain stable milling performance.<\/p>

Unsuitable Milling Process<\/h2>

Different rice varieties have different grain structures, hardness, and moisture requirements. Using the same settings for every variety can increase breakage, even when using a properly designed rice milling machine<\/strong>.<\/p>

Solution:<\/strong> Adjust the milling process according to the rice variety, raw material condition, and finished-rice requirements.<\/p>

How to Reduce Broken Rice with a Rice Milling Machine?<\/h2>

Reducing broken rice requires control of the entire processing process, not just the whitening stage. A typical rice milling machine<\/strong> production line may include:<\/p>

Cleaning \u2192 Destoning \u2192 Husking \u2192 Paddy Separation \u2192 Whitening \u2192 Polishing \u2192 Grading \u2192 Color Sorting \u2192 Packaging<\/strong><\/p>

Properly matched equipment, stable feeding, suitable operating parameters, and regular maintenance can help improve whole-rice yield and finished-rice quality.<\/p>

What to Check When Broken Rice Suddenly Increases?<\/h2>

If the broken rice rate suddenly increases when operating a rice milling machine<\/strong>, check these factors first:<\/p>
