Solutions for Improving the Drying Effectiveness of Rice Dryers.

There are various methods for drying rice, among which the most convenient and efficient approach is to use a rice dryer to quickly reduce the moisture content of a large quantity of rice in a short period of time. This method is particularly suitable for customers with high yields, as it not only accelerates the drying process but also prevents rain damage or mold growth caused by adverse weather conditions. However, using a rice dryer does not always guarantee satisfactory results, which can be frustrating. Today, we will discuss some solutions for improving the drying effectiveness of rice dryers. While these methods may not apply to all models, most issues can be resolved by following the steps below.

The key factor in drying rice is temperature.

Once the temperature is adjusted properly, half the job of drying rice is done. Some users try to increase the efficiency of drying by setting the equipment's temperature very high, but this often results in either exploded or shattered rice grains, with very few remaining intact. In fact, low-temperature drying is necessary for rice drying. The internal temperature of the equipment should be maintained at 65-60℃. Of course, this also depends on the moisture content of the rice. If the moisture content is high, it may be necessary to raise the temperature by 3-5 degrees and repeat the drying process. The number of times and amount of precipitation required for drying should be determined based on the variety and moisture content of the rice as well as storage and processing requirements. Generally speaking, japonica rice with a moisture content below 18% should be dried once until it reaches a standard hardness level; while indica rice with a moisture content between 16%-20% should be dried twice. Grain that needs to be dried must be cleaned first to ensure that its quality after supply and heat consumption are reduced. After drying, grain must undergo a 2-4 hour cooling period. The power of the fan at the end of the equipment must ensure that there is sufficient voltage so that it can draw out high-humidity gas after drying. Unstable voltage can result in insufficient suction power which causes moisture to condense into water droplets at the end of dryer and drip back onto dry rice grains, increasing their humidity level once again.

The primary reason for the unsatisfactory drying effect reported by users is due to incorrect operation of the rice dryer.

Some users make minor modifications to the equipment, such as adding a bag at the fan outlet to avoid smoke scattering and affecting visibility, without realizing that this bag affects the suction power of the fan. As a result, a large amount of moisture accumulates inside the dryer and cannot be dispersed, leading to rice that is still relatively moist after drying. Therefore, it is recommended that users refrain from making any modifications to the equipment after purchase and follow correct operating procedures in order to achieve optimal drying results.
