WE ARE HERE

The pilot product of agitated nutsche filter dryer (ANFD) is a multifunctional device developed for multipurpose production operations. Promas Engineer’s ANFD is outfitted with numerous features subsequent the most recent styles and technological innovation such as, equal capacity filtrate assortment receiver underneath vacuum, solvent, restoration, compact style, heating preparations, chilling preparations, lifting & decreasing. The filters are intended to satisfy extreme cGMP and Food and drug administration specifications and demanding requirements for filters utilized in the manufacturing of pharmaceutical factors. All merchandise soaked surfaces are made without dead places, clean inner transitions, and no bolted connections to empower ideal cleanability employing CIP programs and best inspection pursuing the cleaning process. The filters have an openable filter foundation delivering quick entry to the filter inside factors for cleansing and inspection.


Promas Agitated Nutsche Filter Dryers are developed to meet all the requirements and are ideal for a extensive assortment of pharmaceuticals together with good chemical applications. Our equipment are appropriate for safe environments, and we have customised styles for cleanroom installation. Agitated nutsche filter dryer (ANFD) is pre-configured gear for multi-merchandise pilot-scale tests. It is a portable filtering technique that is basic to established up and use. When when compared to custom-developed devices, the standardised style eradicates the cost.

The pharmaceutical sectors depend on the correct technologies and companies for filtration, drying, and agitation. Our in-property manufacturing capabilities encompass a vast selection of tools, programs, and features that allow us to supply large-functionality and value-successful operations process options.

Working Basic principle


The basic attention to layout information can make it feasible to simplify the unit validation. The agitator is supported from the leading and is externally installed on the stirring, the addresses and the shaft seal. The shaft sealing is with a mechanical double monitor and a mounted bellow. The agitator’s arms are equipped with a especially developed surface area 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 direct to an incredibly successful mixing of the total model mass for the mixing and drying approach. The arms of the agitator are S-fashioned for much better launch of the merchandise. All soaked product surfaces are heated to attain the optimum heat trade spot feasible, resulting in fast drying instances and lower ultimate humidity.

Working Sequence

The agitated nutsche filter dryer entails refined valves and hydraulics manipulation this sort of that current installations are fully automatic.

Filtration Method

The slurry is poured into the filter, and force is used to displace the filtrate, leaving the cake on the filter media. There is a chance of segregation in slurries with a vast distribution of coarse rapidly settling solids and gradual settling fines, with the finer fraction settling over the coarse. Simply because the particles seal the cake and inhibit its generation, retaining 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 means of a spray ring or connections on best of the protect. A single of the benefits of making use of the Nutsche Filter is that it makes it possible for you to smooth the cake’s surface prior to spray washing it, guaranteeing that the total bed is uniformly cleaned. In a multi-washing method, washing effectiveness can be enhanced even far more if air or gas is not allowed to sign up for the cake, so the clean liquids persistently displace the treatments in a piston-like way.

Drying Method

Air or gas purges the item in the course of the drying stage till the trapped moisture is diminished to an asymptotic stage, at which point the cake is considered as dry as achievable. The cake is smoothed by alternating the rotation of the paddle or auger arms and applying regulated strain to its surface with the hydraulic method to obtain the most affordable achievable humidity articles. This stops air or fuel from escaping the mattress by sealing cracks in the merchandise.

Drying in the Vacuum

Scrape and de-lump the item whilst slowly rotating and decreasing the paddle arms to further decrease item humidity. To make the most of the Nutsche Filter’s drying abilities, think about heating parts like the vessel, filter ground, and paddles.
