The Filter-Wash-Dry (FWD) integrated equipment, commonly known as the Agitated Nutsche Filter Dryer (ANFD) or Filter-Wash-Dry System, is a highly integrated advanced unit operation equipment. This system can continuously complete three critical processes—filtration, washing and drying—in a single closed vessel, eliminating the need for material transfer throughout the entire production process.



Founded in 1976, Wuxi Zhanghua Pharm& Chem Equipment Co., Ltd. has been deeply engaged in the field of core equipment for pharmaceutical and fine chemical industries. It has accumulated extensive engineering experience in structural design, material selection, closed safety assurance and process scale-up verification of the filter-wash-dry integrated system.



This integrated process design is particularly suitable for production scenarios with stringent requirements for product purity, personnel safety, environmental control and regulatory compliance. It has now become one of the key core equipment in modern pharmaceutical and high-end material manufacturing sectors.

The revised national standard GB/T 30583—2026 “Post-Weld Heat Treatment of Pressure Equipment” has been officially released. In this revision, the Indentation Energy Difference Method has been incorporated into Appendix G and listed as an optional method for evaluating post-weld heat treatment effectiveness. Its inclusion signifies that residual stress testing based on instrumented indentation technology has formally entered China’s national standard framework.
