How to Control the Moisture Content of a Dryer Well

Controlling moisture is the key to successful operation, usually through the use of relevant or more specific programs for offline flow analysis, in order to take timely measures to prevent serious problems and improve the efficiency of the dryer.

The manufacturer of the double cone rotary vacuum dryer introduces that under normal circumstances, if all inlet parameters remain unchanged, there should be no significant change in the moisture content of the product outlet during the operation of the dryer. However, in many cases, changes in inlet parameters will affect the occurrence of drying rate. These changes may occur at a lower frequency, using laboratory or desktop methods to measure the moisture content of the product, which can change the drying process conditions and achieve a constant moisture content in the dryer.

In many processing plants, the frequency of changes may be too high, requiring manual changes to exceed the measured moisture content during the drying process. In these cases, the use of online humidity sensors and continuous control systems can achieve the economic significance of constant product moisture. Another strategy to maintain a constant drying rate is to improve the heat and mass transfer rates of the dryer model. The temperature change (heat) during the measurement process can make the evaporation rate (mass transfer) predictable, while maintaining a constant outlet moisture content throughout the entire process.

The manufacturer of the double cone rotary vacuum dryer introduces that many instruments are convenient for monitoring and measuring the working conditions of the dryer, and obtaining measurements of air and product characteristics can lead to specific drying processes. By increasing understanding, it involves the overall efficiency of the factory and the quality attributes of the product.
