WE ARE HERE

The pilot product of agitated nutsche filter dryer (ANFD) is a multifunctional equipment produced for multipurpose producing functions. Promas Engineer’s ANFD is geared up with numerous functions adhering to the most current designs and technologies this sort of as, equivalent capability filtrate assortment receiver below vacuum, solvent, restoration, compact style, heating preparations, chilling preparations, lifting & decreasing. The filters are intended to meet extreme cGMP and Fda specifications and demanding requirements for filters utilised in the production of pharmaceutical components. All merchandise soaked surfaces are made with no lifeless places, sleek interior transitions, and no bolted connections to empower optimum cleanability employing CIP techniques and optimal inspection adhering to the cleansing approach. The filters have an openable filter base providing instant entry to the filter inside parts for cleansing and inspection.


Promas Agitated Nutsche Filter Dryers are developed to meet up with all the requirements and are ideal for a broad variety of prescription drugs alongside with good chemical programs. Our equipment are suited for risk-free environments, and we have customised styles for cleanroom set up. Agitated nutsche filter dryer (ANFD) is pre-configured products for multi-solution pilot-scale testing. It is a portable filtering program that is basic to established up and use. When in contrast to personalized-created units, the standardised layout eliminates the cost.

The pharmaceutical sectors count on the proper technologies and solutions for filtration, drying, and agitation. Our in-property manufacturing abilities encompass a extensive selection of gear, methods, and functions that allow us to supply higher-functionality and value-powerful operations method answers.

Operating Basic principle


The general interest to design specifics can make it attainable to simplify the device validation. The agitator is supported from the prime and is externally mounted on the stirring, the addresses and the shaft seal. The shaft sealing is with a mechanical double display and a fixed bellow. The agitator’s arms are equipped with a notably developed area and thrust the cake on the reverse clockwise rotation and mix and stir the cake on turning in the reverse path.

Simultaneous circular and vertical motions of the agitator guide to an very successful mixing of the total product mass for the mixing and drying procedure. The arms of the agitator are S-formed for better release of the product. All soaked item surfaces are heated to accomplish the optimum heat exchange area possible, ensuing in rapid drying moments and reduced supreme humidity.

Working Sequence

The agitated nutsche filter dryer requires advanced valves and hydraulics manipulation this sort of that present installations are completely automated.

Filtration Process

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 rapidly settling solids and slow settling fines, with the finer fraction settling above the coarse. Since the particles seal the cake and inhibit its generation, retaining the slurry suspended with rotating arms in the course of filtration aids in the development of a uniform cake.

Washing Cake

During the washing stage, the wash liquid is utilized to the cake through a spray ring or connections on best of the protect. 1 of the rewards of employing the Nutsche Filter is that it enables you to sleek the cake’s floor ahead of spray washing it, guaranteeing that the total bed is uniformly cleaned. In a multi-washing system, washing performance can be enhanced even much more if air or gasoline is not allowed to be a part of the cake, so the wash liquids consistently displace the solutions in a piston-like method.

Drying Procedure

Air or gas purges the solution in the course of the drying stage till the trapped moisture is reduced to an asymptotic amount, at which point the cake is deemed as dry as possible. The cake is smoothed by alternating the rotation of the paddle or auger arms and implementing regulated force to its surface with the hydraulic method to achieve the least expensive achievable dampness content. This stops air or gasoline from escaping the mattress by sealing cracks in the item.

Drying in the Vacuum

Scrape and de-lump the product although gradually rotating and lowering the paddle arms to additional lessen merchandise dampness. To make the most of the Nutsche Filter’s drying capabilities, take into account heating factors like the vessel, filter flooring, and paddles.
