Every little thing you want to know about Agitated Nutsche Filter Dryer

The pilot model of agitated nutsche filter dryer (ANFD) is a multifunctional equipment produced for multipurpose manufacturing operations. Promas Engineer’s ANFD is outfitted with several functions adhering to the latest styles and technologies these kinds of as, equal potential filtrate selection receiver beneath vacuum, solvent, recovery, compact layout, heating arrangements, chilling preparations, lifting & lowering. The filters are supposed to satisfy serious cGMP and Food and drug administration specs and demanding demands for filters utilised in the production of pharmaceutical factors. All products soaked surfaces are made with no dead places, smooth interior transitions, and no bolted connections to empower ideal cleanability utilizing CIP methods and optimal inspection pursuing the cleaning process. The filters have an openable filter base delivering quick access to the filter interior components for cleaning and inspection.


Promas Agitated Nutsche Filter Dryers are made to fulfill all the expectations and are suited for a broad selection of pharmaceuticals together with fine chemical programs. Our machines are suited for secure environments, and we have customised designs for cleanroom set up. Agitated nutsche filter dryer (ANFD) is pre-configured gear for multi-item pilot-scale tests. It is a transportable filtering method that is easy to set up and use. When when compared to custom made-developed products, the standardised design and style eliminates the cost.

The pharmaceutical sectors count on the appropriate technologies and companies for filtration, drying, and agitation. Our in-house producing capabilities encompass a wide selection of gear, techniques, and attributes that enable us to provide high-efficiency and expense-effective functions process answers.

Functioning Principle


The standard interest to style information makes it possible to simplify the unit validation. The agitator is supported from the top and is externally set up on the stirring, the handles and the shaft seal. The shaft sealing is with a mechanical double display screen and a fastened bellow. The agitator’s arms are fitted with a particularly developed surface and push the cake on the reverse clockwise rotation and combine and stir the cake on turning in the reverse direction.

Simultaneous round and vertical motions of the agitator guide to an extremely effective mixing of the whole model mass for the mixing and drying method. The arms of the agitator are S-formed for far better launch of the product. All soaked solution surfaces are heated to accomplish the maximum warmth trade spot feasible, ensuing in swift drying times and low ultimate humidity.

Operating Sequence

The agitated nutsche filter dryer includes innovative valves and hydraulics manipulation this sort of that present installations are totally automated.

Filtration Approach

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 probability of segregation in slurries with a vast distribution of coarse fast settling solids and gradual settling fines, with the finer portion settling more than the coarse. Because the particles seal the cake and inhibit its generation, maintaining the slurry suspended with rotating arms in the course of filtration aids in the formation of a uniform cake.

Washing Cake

For the duration of the washing phase, the clean liquid is utilized to the cake by way of a spray ring or connections on best of the include. A single of the rewards of utilizing the Nutsche Filter is that it enables you to clean the cake’s area just before spray washing it, ensuring that the entire bed is uniformly cleaned. In a multi-washing program, washing performance can be improved even much more if air or gasoline is not authorized to join the cake, so the wash liquids consistently displace the cures in a piston-like manner.

Drying Procedure

Air or fuel purges the product throughout the drying phase until finally the trapped dampness is diminished to an asymptotic degree, at which position 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 stress to its floor with the hydraulic system to accomplish the cheapest achievable humidity content. This stops air or gasoline from escaping the mattress by sealing cracks in the solution.

Drying in the Vacuum

Scrape and de-lump the product although slowly and gradually rotating and decreasing the paddle arms to more reduce product dampness. To make the most of the Nutsche Filter’s drying abilities, think about heating parts like the vessel, filter floor, and paddles.
