The pilot model of agitated nutsche filter dryer (ANFD) is a multifunctional device produced for multipurpose producing operations. Promas Engineer’s ANFD is geared up with many features adhering to the latest types and engineering these kinds of as, equal capability filtrate collection receiver under vacuum, solvent, recovery, compact design, heating preparations, chilling arrangements, lifting & lowering. The filters are meant to meet severe cGMP and Fda specs and demanding requirements for filters utilised in the production of pharmaceutical elements. All goods soaked surfaces are developed without dead spots, clean internal transitions, and no bolted connections to allow the best possible cleanability making use of CIP techniques and optimal inspection pursuing the cleaning process. The filters have an openable filter base providing instant access to the filter inner factors for cleaning and inspection.


Promas Agitated Nutsche Filter Dryers are developed to meet all the standards and are appropriate for a vast range of prescription drugs along with good chemical purposes. Our devices are suited for risk-free environments, and we have customised types for cleanroom installation. Agitated nutsche filter dryer (ANFD) is pre-configured gear for multi-item pilot-scale tests. It is a portable filtering program that is basic to established up and use. When when compared to custom made-created gadgets, the standardised style eliminates the expense.

The pharmaceutical sectors count on the proper technologies and providers for filtration, drying, and agitation. Our in-property producing capabilities encompass a vast variety of tools, programs, and characteristics that permit us to provide higher-efficiency and price-effective operations approach options.

Functioning Basic principle


The common consideration to design and style information makes it attainable to simplify the unit validation. The agitator is supported from the top and is externally put in on the stirring, the addresses and the shaft seal. The shaft sealing is with a mechanical double screen and a mounted bellow. The agitator’s arms are equipped with a notably developed surface and drive the cake on the reverse clockwise rotation and mix and stir the cake on turning in the reverse direction.

Simultaneous round and vertical motions of the agitator lead to an really successful mixing of the entire model mass for the mixing and drying method. The arms of the agitator are S-fashioned for greater launch of the item. All soaked item surfaces are heated to achieve the highest heat trade area possible, resulting in rapid drying moments and minimal ultimate humidity.

Working Sequence

The agitated nutsche filter dryer involves innovative valves and hydraulics manipulation these kinds of that present installations are entirely automatic.

Filtration Procedure

The slurry is poured into the filter, and stress is utilized to displace the filtrate, leaving the cake on the filter media. There is a chance of segregation in slurries with a extensive distribution of coarse quick settling solids and sluggish settling fines, with the finer portion settling over the coarse. Because the particles seal the cake and inhibit its production, keeping the slurry suspended with rotating arms throughout filtration aids in the formation of a uniform cake.

Washing Cake

During the washing phase, the wash liquid is utilized to the cake through a spray ring or connections on leading of the go over. A single of the advantages of making use of the Nutsche Filter is that it makes it possible for you to easy the cake’s surface area prior to spray washing it, ensuring that the whole bed is uniformly cleaned. In a multi-washing technique, washing efficiency can be improved even more if air or gasoline is not authorized to join the cake, so the wash liquids persistently displace the treatments in a piston-like way.

Drying Procedure

Air or gasoline purges the item during the drying phase until the trapped moisture is reduced to an asymptotic amount, at which stage the cake is considered as dry as possible. The cake is smoothed by alternating the rotation of the paddle or auger arms and implementing controlled pressure to its area with the hydraulic technique to accomplish the lowest possible humidity content. This prevents air or fuel from escaping the bed by sealing cracks in the product.

Drying in the Vacuum

Scrape and de-lump the item even though little by little rotating and decreasing the paddle arms to more reduce solution moisture. To make the most of the Nutsche Filter’s drying capabilities, contemplate heating components like the vessel, filter ground, and paddles.
