The pilot model of agitated nutsche filter dryer (ANFD) is a multifunctional equipment developed for multipurpose production operations. Promas Engineer’s ANFD is geared up with numerous characteristics following the latest patterns and engineering this kind of as, equal capacity filtrate assortment receiver below vacuum, solvent, recovery, compact design and style, heating arrangements, chilling arrangements, lifting & reducing. The filters are supposed to meet up with severe cGMP and Fda specifications and demanding needs for filters used in the production of pharmaceutical parts. All goods soaked surfaces are designed with no dead spots, sleek inner transitions, and no bolted connections to allow the best possible cleanability using CIP programs and best inspection following the cleansing process. The filters have an openable filter base supplying fast obtain to the filter inner parts for cleansing and inspection.


Promas Agitated Nutsche Filter Dryers are designed to meet up with all the specifications and are suitable for a wide range of prescription drugs together with good chemical apps. agitated nutsche filter dryer manufacturer are appropriate for risk-free environments, and we have customised patterns for cleanroom set up. Agitated nutsche filter dryer (ANFD) is pre-configured gear for multi-item pilot-scale testing. It is a transportable filtering method that is easy to established up and use. When in contrast to personalized-constructed devices, the standardised layout eliminates the expense.

The pharmaceutical sectors depend on the right technologies and services for filtration, drying, and agitation. Our in-home production capabilities encompass a broad assortment of products, systems, and characteristics that allow us to offer substantial-functionality and price-efficient functions process solutions.

Operating Theory


The standard consideration to style specifics helps make it attainable to simplify the device validation. The agitator is supported from the top and is externally mounted on the stirring, the addresses and the shaft seal. The shaft sealing is with a mechanical double display screen and a fastened bellow. The agitator’s arms are equipped with a especially made surface and drive the cake on the reverse clockwise rotation and blend and stir the cake on turning in the reverse course.

Simultaneous round and vertical motions of the agitator direct to an incredibly efficient mixing of the entire design mass for the blending and drying procedure. The arms of the agitator are S-formed for far better launch of the merchandise. All soaked item surfaces are heated to obtain the maximum heat trade spot possible, ensuing in quick drying occasions and low final humidity.

Functioning Sequence

The agitated nutsche filter dryer involves refined valves and hydraulics manipulation such that present installations are fully automated.

Filtration Procedure

The slurry is poured into the filter, and pressure is used to displace the filtrate, leaving the cake on the filter media. There is a possibility of segregation in slurries with a wide distribution of coarse rapidly settling solids and slow settling fines, with the finer portion settling over the coarse. Due to the fact the particles seal the cake and inhibit its manufacturing, retaining the slurry suspended with rotating arms for the duration of filtration aids in the formation of a uniform cake.

Washing Cake

Throughout the washing phase, the clean liquid is used to the cake by means of a spray ring or connections on top of the protect. One particular of the rewards of using the Nutsche Filter is that it enables you to sleek the cake’s surface before spray washing it, making certain that the whole bed is uniformly cleaned. In a multi-washing system, washing effectiveness can be improved even much more if air or fuel is not allowed to be a part of the cake, so the clean liquids constantly displace the remedies in a piston-like manner.

Drying Procedure

Air or fuel purges the product during the drying phase until finally the trapped dampness is diminished to an asymptotic degree, at which position the cake is considered as dry as feasible. The cake is smoothed by alternating the rotation of the paddle or auger arms and making use of regulated strain to its floor with the hydraulic program to accomplish the lowest achievable dampness content material. This helps prevent air or gasoline from escaping the mattress by sealing cracks in the merchandise.

Drying in the Vacuum

Scrape and de-lump the solution although slowly rotating and reducing the paddle arms to more reduce item dampness. To make the most of the Nutsche Filter’s drying abilities, take into account heating elements like the vessel, filter ground, and paddles.
