Agitated Nutsche Filter & Dryer (ANFD)
Filtration, Washing & Drying – All in One Sealed Operation
Shree Shakti Engineering Works designs and fabricates Agitated Nutsche Filter Dryers (ANFDs) used for critical solid-liquid separation processes in pharmaceutical, chemical, API, and intermediate industries. ANFDs allow filtration, cake washing, drying, and discharge in a fully sealed, GMP-compliant environment — eliminating product contamination and operator exposure.
Our ANFDs are available in manual, semi-automatic, and fully automated configurations, designed to meet FDA / GMP / cGMP requirements for sterile operations.
