Advanced R&D Filtration, Washing & Vacuum Drying Solution for Pharma, API & Specialty Chemical Applications
Process development and laboratory-scale trials require equipment that can accurately reproduce the critical steps of a production process. An Agitated Nutsche Filter Dryer (ANFD) provides an integrated solution for filtration, cake washing and vacuum drying within a single vessel.
DSEW – Dwaraka Sai Engineering Works offers R&D-scale ANFD systems from 2 Liters to 50 Liters, designed for laboratory development, process optimization and scale-up studies.
What is an R&D ANFD?
An Agitated Nutsche Filter Dryer is a closed process vessel that combines solid-liquid separation and drying operations.
Unlike conventional arrangements where filtration, washing and drying may require separate equipment, an ANFD allows these operations to be performed in the same vessel.
This makes it particularly useful during pharmaceutical and API process development, where maintaining product containment and minimizing product handling can be important.
R&D ANFD Capacity Range: 2 L to 50 L
Our R&D ANFD range covers:
2 Liters | 5 Liters | 10 Liters | 20 Liters | 30 Liters | 50 Liters
The equipment can be configured according to the process requirements, product characteristics, filtration area and desired operating conditions.
Key Features of R&D ANFD
1. Filtration
The ANFD is equipped with a suitable filter medium for solid-liquid separation. Sintered metal filter media can be provided for applications requiring robust and reusable filtration surfaces.
2. Cake Washing
After filtration, the cake can be washed inside the same vessel. The agitator helps in controlled cake mixing and washing according to the process requirement.
3. Vacuum Drying
Following filtration and washing, the product can be dried under vacuum. This provides an integrated approach to moisture removal without transferring the product to a separate dryer.
4. Agitator System
The agitator is designed to support process operations such as:
- Cake washing
- Cake mixing
- Cake smoothing
- Drying assistance
- Product discharge
5. Material of Construction
Depending on the application, the R&D ANFD can be manufactured in materials such as:
- SS316L
- Hastelloy
Material selection can be customized according to product compatibility and process requirements.
Sintered Metal Filter Media
For suitable applications, sintered metal filter media can be used as the filtration surface.
Sintered metal media provides a rigid filtration structure and can be selected according to the required filtration characteristics.
The filter media configuration can be finalized based on the product, particle characteristics and process conditions.
Applications of R&D ANFD
The 2 L to 50 L R&D ANFD range is suitable for:
- Pharmaceutical R&D
- API Development
- Process Development
- Specialty Chemicals
- Laboratory Trials
- Filtration Studies
- Cake Washing Studies
- Drying Studies
- Process Scale-Up Studies
Why Use an R&D ANFD?
During process development, it is important to understand how filtration, washing and drying parameters behave before moving toward larger production equipment.
An R&D ANFD provides the opportunity to study these operations on a controlled laboratory or development scale and generate useful process data for subsequent scale-up.
The integrated design also reduces unnecessary product transfers between separate filtration and drying equipment.
Customized R&D ANFD Solutions
Every process has different requirements. Therefore, the R&D ANFD can be customized based on:
Capacity | Filter Area | Filter Media | MOC | Agitator Configuration | Vacuum Requirements | Product Characteristics | Discharge Arrangement
Our engineering team can develop the equipment configuration according to the customer’s specific process requirements.
From R&D to Production Scale
The objective of R&D equipment is not simply to perform laboratory trials. It is to generate meaningful process information that can support the transition from laboratory development to larger-scale production equipment.
With R&D ANFD capacities from 2 Liters to 50 Liters, DSEW provides a compact solution for filtration, washing and vacuum drying studies across pharmaceutical, API and specialty chemical applications.
