Why does drying rice result in more broken grains?

Using rice dryers to dry rice has become commonplace, with various types of equipment such as tower and drum dryers being used in different regions. People have different opinions on the equipment, but regardless, rice dryers have increased the speed of storing rice, solved many problems encountered during rice harvesting, and ensured an adequate supply of rice. However, some users may encounter issues when using these dryers, such as finding more broken grains after drying the rice. If the grains are broken, it will lower the quality of the rice and make it difficult to sell at a good price. Let's analyze why there are more broken grains during drying.

Why does broken rice occur during drying?

In fact, this is closely related to the drying process. The process of the rice dryer simulates the principle of natural sun-drying, but speeds up the process. Natural sun-drying takes 2-3 days to complete, but using a dryer only takes 2-3 hours. However, when rice encounters high temperatures and loses a large amount of moisture quickly, its surface will crack and break under the action of the lifting plate in the dryer, resulting in more broken rice. In summary, this is caused by improper handling of production processes and blind use. This is only one reason; another reason is that poor design of the internal structure of the dryer can also result in more broken rice. The lifting plate is a crucial part of the dryer; it lifts and agitates the rice to increase its contact time and frequency with hot air flow. If the design of the lifting plate is not reasonable, it may cause the rice to fall directly and break into pieces, resulting in a large area of broken rice. Other minor issues such as excessively high inlet temperature can also lead to an increased rate of broken rice, which needs to be addressed during production.

When we find that there is too much-broken rice, we need to analyze the reasons and find solutions promptly by adjusting equipment operating parameters. If you do not know how to solve it, you can contact technical personnel from the manufacturer for video guidance during downtime before resuming production once you have mastered it.
