In this process vacuum is applied on the top of the vessel through dust filter as agitated nutsche filter dryer as on bottom of the vessel, which will accelerate the drying process.

Our ANFD’s feature a differential mixing agitator and paddle that moves vertically for a thorough mix performance.

Versatility agitated nutsche filter dryer achieved in filtration, washing, re-slurring and drying with complete automation thus reducing the capital and operating costs. Additionally, these can be combined with automatic packing systems further downline. The ANFD is used to maintain a uniform cake, improving the quality of the delivered product. The key benefits of the S2 ANFD solution include; Slurry contents are kept fluidized until most of the mother liquor is filtered.

Views Read Edit View history. It consists of vessel with Dish ends and a perforated plate in between. Creation of a microenvironment limiting impact on the cleanroom. Particularly suited for agitated nutsche filter dryer handling of cytotoxic or highly potent material HPAPIthe De Dietrich solution has been agitated nutsche filter dryer with particular attention to ergonomics and practicality, whilst also maintaining cleanability.


The entire vessel can be kept at the desired temperature by using a limpet jacket, jacketed bottom dish and stirrer blade agitateed shaft through which heat transfer media can flow. Displacement washing serves several purposes — it removes the cilter and agitafed impurities while keeping the cake intact and it replaces the previous liquid with fresh liquid.

There are two types of drying that can be conducted — vacuum drying and convection drying.

Also solvent recovery, handling of toxic and hazardous materials without human intervention is easily achieved. No let off of toxic solvent vapors in the atmosphere. From an environmental and agitated nutsche filter dryer health perspective, safety is maintained throughout the process.

Compared to exotic alloy materials, chemical resistant coatings provide a lower coat of supply solution when processing highly aggressive substances. nutdche

This design is good for vacuum as well as high pressure applications. The filter should be sized appropriately to handle the solids volume that is being charged. Various materials of construction including L stainless agitated nutsche filter dryer, Alloy 20, C and others. Click here for information about Sunrax Process Technologies.

S2’s is part of a Group of Companies which includes Schematic Engineering Industries – a leading supplier of barrier isolators. Washing of the cake can be performed in the same tank by reslurrying the cake.

Side Discharge Valve – Metal-to-metal seals with minimal dead space, eliminating the agitated nutsche filter dryer issues that can arise with the use of o-rings.

Understanding the Nutsche Filtration and Drying Process

Filter-Dryers nugsche numerous advantages: The ANFD provides filtration under vacuum or pressure in a closed-loop system, a sealed vessel where solids can be discharged straightaway into a dryer. Designed and built by De Dietrich – perfect integration with your filter-dryer. The media should be determined based on the characteristics of the slurry including particle size and shape, cake porosity, and compressibility which are all factors that, when taken into account with the filter media selected, will determine filtration rate.

ANSI agitated nutsche filter dryer B After washing, the mother liquor can be refiltered. Remember me Remember me. Retrieved from ” https: Sterile filter-dryers For drysr requiring sterile manufacturing conditions, filter-dryer can be specifically designed to agitated nutsche filter dryer stem-in-place SIP capabilities, and eliminate all internal dead spaces.

This next step may be used after any filtration or wash, especially after the final wash, when gas is blown through the cake. The agitator is slowly lowered as it rotates, effectively moving product nutache the side discharge valve. Mutsche is charged into filter preferably by gravity flow from reactor installed above the filter or by slurry pump.

Agitated Nutsche Filter

The cake can then be discharged by lowering the agitator and rotating it in such a manner that it brings all the cake towards the discharge port. The ANFD comprises of a pressure vessel in which a main shaft rotates and also moves in the vertical agitated nutsche filter dryer.

Here, fresh wash liquid is sprayed on top of the solid cake taking care not to disturb the surface of the cake.

The liquid is forced through with pressure or vacuum.
