Powder Systems Limited are pharmaceutical and chemical processing experts, offering a wide range of solutions for research, development, and large-scale applications. Our solutions are suitable for filtration, drying, and other processes, such as product sampling and product discharge, and we also provide aftercare services to support our clients.
We design and manufacture filter dryer systems used in pharmaceuticals and are recognised worldwide for our efficiency in solid-liquid processing. Our Agitated Nutsche Filter Dryers (ANFD) can scale-up from the laboratory to commercial manufacturing via our GFDⓇ, SimpleFilter and production-sized ANFD ranges. These systems efficiently wash and isolate solids while overcoming traditional production method limitations.
ANFD is a piece of equipment that facilities filtration and drying processes by combining the two into a single operation. It is commonly used in the pharmaceutical industry to produce APIs and other fine chemicals.
In a filter-dryer, the mixture of solid and liquid is filtered under pressure through a filter medium, which separates the solid and liquid components. The filter cake, which is the solid material, is then dried by introducing a gas, such as nitrogen or air, through the cake. This gas helps to remove the remaining liquid from the solid material and results in a dry, free-flowing powder. This is an incredibly simple explanation of the process, and there are various peripheral benefits and considerations. For more information, refer to our detailed blog on How an Agitated Nutsche Filter Dryer Works. ANFD provides several benefits over traditional drying methods, including reduced processing times, improved product quality, and lower production costs. It is particularly useful for products that are heat-sensitive, hygroscopic, or prone to oxidation.
