Thermosag India Pvt Ltd  is one of the biggest agitated nutsche filter dryer manufacturer in India. We own a high reputation in the Indian market for providing featured ANFDs that contain unique benefits and advantages.

What is an ANFD?

  • An Agitated Nutsche Filter-Dryer (ANFD) is a specialized piece of equipment commonly used in the fine chemical and pharmaceutical industries, particularly for filtering active pharmaceutical ingredients (API) after crystallization. This multi-functional equipment can perform various operations in a single batch, including filtering, washing, re-slurring, and drying, all within a fully enclosed vessel.
  • ANFDs come in a range of sizes, from 20 liters to 20,000 liters, and there are various options available, including cGMP, Pharma, and sterile applications, to meet different needs.
  • We offer a range of MOCs including Stainless Steel, Hastelloy®, other Nickel based and exotic alloys and also cladded, polymer-lined or glass-lined construction Suitable for a large majority of chemical products. Lab and pilot scale trials are also available.
  • Thermosag is one of the biggest ANFD manufacturers globally. We own a high reputation in the Indian market for providing featured ANFDs that contain unique benefits and advantages.

    Process We Follow at Thermosag India Pvt Ltd

    The main function of agitated nutsche filtration and drying is to isolate solids in batch-oriented processing. There are various methods of recovering APIs from a slurry, but the most obvious advantage of nutsche filters dryer is the combination of slurry filtration, product washing, and vacuum drying processes into a single unit.

    Where is Nutsche Filter Used?

    Our ANFDs perform efficiently in industries like Pharma and Chemical, wherein filtration and cake washing are required. The wet cake can be completely dried and discharged as a powder through the use of a jacket on the vessel, heated blades on the agitator, and operation under vacuum, all in one unit.

    Advantages of Nutsche Filter Dryers 

    1. Exceptional Solvent Recovery
    2. Flexible Filtration Options
      • Can be performed under vacuum or pressure
      • Maintains gaseous atmosphere
    3. Increased Safety and Efficiency
      • Reduced staffing requirements
      • No hazardous vapours escape
      • Personal safety ensured
      • Heat transfer surfaces maintain constant filtration temperature
      • No product handling by hand
    4. Thorough Filtration Process
      • Agitator rotates in multiple directions for thorough washing and re- slurring
    5. Versatile and Safe Treatment of Materials
      • Can treat toxic and hazardous materials
      • Preserves product purity
    6. Additional Product Features
      • Ability to blend the product before release
      • Low cost solvent cleaning option
      • PLC-based automation
    7. Streamlined Process and Lower Costs
      • Combined filtration, washing, re-slurrying, and drying in one fully enclosed, automated machine
      • Lower capital and operational expenses
      • Quick processing of large quantities
      • Reduced number of traditional filtration equipment
      • Designed for maximum product recovery yield

    FAQ

    Why use an Agitated Nutsche Filter Dryer instead of separate filter + dryer machines?

    Combining these steps in an ANFD saves time, labor, and contamination risk by performing all processes in one vessel—reducing transfers, handling hazards, and improving control. Agitation further speeds up washing and drying, ensuring uniform results.

    What are the important design features to consider when selecting an Agitated Nutsche Filter Dryer?

    Key ANFD design features include good agitation, strong heating/vacuum, reliable seals, easy cleanability (CIP), and safe solvent handling.

    What is the working principle of Agitated Nutsche Filter Dryer?

    In an ANFD batch, slurry is loaded and filtered to separate solids from liquid. The solid material is washed, dried with heat and vacuum, and smoothed to remove extra moisture. Finally, the dried material is discharged, and the vessel is cleaned for the next batch.

    Approximate cost/price range of Agitated Nutsche Filter Dryers in India?

    The cost of Agitated Nutsche Filter Dryers in India varies depending on capacity, material, and automation level. Smaller units are more affordable, while large, fully automated, and high-grade models for pharma or chemical use are priced significantly higher.

    What kind of maintenance is needed in an Agitated Nutsche Filter Dryer?

    Regular cleaning prevents buildup, while filter cloths, seals, and drives should be checked and replaced as needed. Ensure the agitator motor runs smoothly and confirm temperature and vacuum systems meet specifications.
