Nutsche Filters and Filter Dryers for Pharmaceutical Companies

Wire mesh can be used in a variety of ways in the pharmaceutical industry. One example is using sintered wire mesh in Agitated Nutsche filters for pharmaceutical processing. However, they can also be used for paints, dyes, and wastewater treatment.

Agitated Nutsche filters work by using a vacuum or pressure in a closed system for solid-liquid separation, wherein the solids can be immediately discharged via a side discharge valve into a dryer.

The filters themselves can be made from stainless steel, Hastelloy, and mild steel. Other components can also be made of rubber or glass lining, as well as polypropylene fiber-reinforced plastic (PPFRP). Components of a Nutsche filter include a dished vessel and a perforated plate with a filter disc on the bottom, although other parts can be added depending on the use case. The filter disc can come in the form of a filter cloth, sintered wire mesh, or perforated support plate with either metallic or non-metallic filter mesh.

Another part is the agitator, which performs a number of essential functions such as maintaining a uniform cake of slurry contents to allow for easier reslurry washing and refiltration of the mother liquor. Lastly, the hydraulic power pack or power unit keeps the system running properly.

Nutsche Filters Applications and Uses

Nutsche filters are great assets in the pharmaceutical industry, or any industry that requires the handling of chemical compounds. Agitated Nutsche filter dryers allow for active chemical ingredients (ACI) or active pharmaceutical ingredients (API) and chemical compounds to filter and dry within the same unit, thus reducing their exposure.

Wire Mesh for Nutsche Filters

Our 5-layer sintered wire mesh laminate is ideal for use in Nutsche filters in the pharmaceutical and chemical industries. This filter medium has the ability to operate under a wide variety of temperatures and pressures while maintaining its opening size. It has excellent corrosion resistance and mechanical strength. And unlike other sintered powder filter media, it has the ability to be cleaned by backwashing.

Sintered Wire Mesh Application: Nutsche filters for Pharmaceutical Applications

Our 5-layer sintered wire mesh laminates are available in a wide variety of filter ratings, in 316L Stainless Steel or Hastelloy. Our standard size 24″x48″ and 48″x48″ pieces can be cut and welded together to form larger circular filters and bolted or welded in place.
