Methods for detecting the moisture content of materials

Thread Content

For the pharmaceutical industry, balancing the moisture content is of great significance in production. When the active pharmaceutical ingredient is placed in a certain environment for a sufficient length of time, its moisture content tends to reach an equilibrium value, known as the equilibrium moisture content EMC of that environment. Moisture content control is a crucial aspect in the pharmaceutical production process, as well as one that is difficult to manage. A moisture meter is currently the most widely used instrument in various industries for measuring moisture content. By using a moisture meter to determine the moisture content of drugs, it becomes possible to better control this level of moisture, reduce waste in drug production, and increase the efficiency of drug utilization. The online infrared moisture meter developed by Hangzhou Puyang Optoelectronics boasts top-tier performance metrics, surpassing the vast majority of other brands in terms of accuracy and stability. Near-infrared measurement technology features fast detection speed, no need for contact with the object being measured, no damage to that object, and the ability to conduct real-time monitoring online. Thanks to its environmentally friendly, rapid, and non-destructive characteristics, it has found wide application in many industries. It can be used at the discharge port of drying towers, in boiling fluidized beds, in front of belt scales, and in front of compressors during pharmaceutical manufacturing. It can effectively improve the quality of the boards produced and the first-time success rate in board production. Closed-loop control can save fuel and reduce the reprocessing rate. Currently, the adoption rate of infrared moisture meters in domestic pharmaceutical factories exceeds 70%, having completely replaced manual testing and resistive moisture meters. The test results are stable, with good performance. 15335330602
