Abstract :
In order to raise Chinese pills´ productive efficiency, a microwave resonator (MR) with a center hole is improved for measuring density and moisture content of Chinese pill material. When pill material passes through the center hole, its density and moisture will cause resonant frequency excursion (RFE) and microwave attenuation (MA). Under the same moisture, density is only related to MA. If RFE and MA are detected, we can calculate density and moisture content of pill material. Based on experimental data, a focusing fuzzy clustering algorithm is presented for modeling response characteristic of the resonator, then a microwave measurement device is designed, and a monitoring system for density and moisture content of Chinese pill material is developed by using this device. Testing results on a Chinese pill production line showed that the system had high measuring accuracy
