DRYING SYSTEMS

Agitated Nutsche Filter & Dryers ( ANF / ANFD )

General Description :-

 

  • (ANF&ANFD) is a very popular technology which is used to meet the current era demands of chemical and pharmaceutical industries for drying and solid washing separation.

  • This technology is helpful in really difficult working condition. ANFD is considered ideal equipment for hazardous and toxic materials.

  • The solution is separated mechanically medium under vacuum or pressure. It contains specially designed height adjustable agitator for effective filtration and better mechanical discharge.

  •  Hence it ensures better recovery of solid. Various operations like washing, drying, mixing, crystallizing, extraction, etc. can be performed in ANF/ANFDs.

  • SERVOTEX   Nutsche Filter/Dryers are used for solid-liquid seperation under pressure and or vaccum. The closed operation ensures a consistent product quality,simple validation and also operational safety.
  • The advanced combination of agitation and hydraulics used in these filter/dryers make them versatile and user friendly. The resulting wet cakes can be re-slurried and washed thoroughly with water or solvents.
  • The discharge of cake is automatic
  • If the process demands filtration in a hot or chilled condition then same can be achieved.
  • Finally drying operation can also be conducted within the same equipment.
  • These filter/dryer can be customized for various processes such as Crystallization,Filtration,De-coloration,Washing and Drying with a variety of options namely different shaft seals,bottom enclosure mechanisms, CIP etc.
  • The size of selection of a filter /Filter-Dryer is purely determined by the volume of cake to be handled in a batch and also the nature of the material to be filtered.
